Few tips, make sure the pipes are super clean, when soldering any fitting start on the easiest joint first as the heat will travel tovthe harder to reach joint, dont over heat, if the flame turns green you have over heated the joint and it will leak ive been a plumber for 45 years and trust me follow these simple rules and you will be an expert in no time
Thankyou,I am learning and a maintenance person have, i found a low heat,taking time to slowly heat joint doesnt burn off flux quickly and dabbling solder from other side of fitting works well,flows well every time
Probably harder with today's silver solder since it has a higher melting point. My shiny copper tubing starts getting dark before reaching the solder melting point. Perhaps it is the flux degrading. I keep the heat mostly on the fitting, not the tubing.
The color of the flame doesn’t have anything to do with how hot the joint is. I don’t quite have 45 years in the trade but I have spent my fair share of time with copper. I have a leak here and there but I’ve soldered many thousands of joints. I agree though, you should always clean your pipe and joint properly.

Roger is an excellent presenter - just the right blend of knowledgeable, skilled, and engaging. As a jeweller, I'm new to this specific kind of soldering, so I feel lucky to have stumbled upon your video before wading through a lot of other inferior content on TH-cam - thank you!
Clever tip about zig-zagging the solder as a rough measurement. I've seen those pre-soldered fittings at the store but assumed they were a new type of push-seal like Sharkbite We love listening to old-school British tradesmen who have a very professional attitude.
Great video, thank you Sir. My house was build in 1945 and I am doing a bathroom reno myself. Your video will surly help this first time solderer :) Thank you!!

Great footage on how it all works. And lots of important tips that I had not seen on other videos, like not overdoing it on the flux and making sure things are dry,
Nice & clear, esp. for beginners. One small appendium, IMV you are going in too close with the flame, and with MAPP gas, higher temperature, its easy to overheat the joint & burn the flux. I nearly always use a torch with butane/propane mix, lower temperature, takes a few seconds longer, but less likely to burn the flux. Also, butane mix a lot cheaper! I use the MAPP torch on bigger fittings when needed.
Regarding not using a naked flame in some places, I've used a paint stripping electric heat gun to solder Yorkshire fittings on 15mm pipes and it worked fine. Took longer to heat the pipe up but the solder flowed fine and made a good joint.
Got set of pipe tongs and heads from a charity shop gor £1 As a joke Work well enough though Take time to heat tho Used on that one joint a little too close for comfort to wall Rest i did old way from habit and speed
Thanks Rodger--another great video-I’m a retired Spark, but have soldered a few pipes in my time--I would concur with you, regarding cleaning the flux from the pipes--absolutely vital--I live on a private estate here in Northern Ireland, and quite a few of of the houses have has leaks in the original copper pipes, and the general consensus is that it was down to the plumber not cleaning the flux from the pipes--
It might depend on what flux exactly you are using. Also not deburring is said to cause leaks close to the joints not exactly at the joints, but close.
This came about just at the right time for me. Replacing an outside tap very soon and the new tap I bought has a Yorkshire fitting. I was going to look up a tutorial because, whilst it seemed obvious how to use it, I'm always keen to sanity check (especially as my soldering experience is all with electrics). You've saved me a search, and also stopped me from unnecessarily buying a specific soldering torch for pipework, as I now realise the gas torch I have will do the job 👍 Cheers. 👍
I used a sample of the SuperPower Plumbers SOS. incredible product Did my outside tap and fitted a radiator in the Conservatory. No leaks after 6 months and so easy to use.
Just started learning how to solder at college last night! This is the best 'learn how to solder' video I've seen on youtube so far, and I've spent all morning watching them all. Cheers mate, really simple but sound advice and tips you gave out!
Great to see you, been a while for me. I’d avoid the wet rag . It’s the rapid temperature change that causes uneven cooling and a possible bad joint. 🙂
Normally Great advise, I would always advise heating the bottom fitting 1st, as heat rises.. never use a wet rag as you say the fitting can crack wait until it has suitable cooled down..
I had to buy a jet swet tool for $60 and sweat in a ball valve because my valves off my water meter don’t hold. I replaced old softener with whole house filter. Looks really nice, I even tappconned mounts and 3/8 rod hangers coming off foundation wall. I used bread trick once prior, it does work you just have to act quick.
Thank you. Just finished City and Guilds level 2 Plumbing and Heating which I really enjoyed! It was a great course. Anyway soldering was a weak point initially, but I got much better with practice, and thank you for some really good tips. I use wire wool rather than emery but that's because it was what I was shown Cheers.
When I first did my Craft City and Guilds we had to learn how to wipe lead joints still got the scar to prove it, as molten lead flowed out of my moleskin onto my wrist never happened again after that
Really interesting, I have a tiny, tiny leak on a push fit joint and I suspect the pipe if just slightly distorted, I think a solder joint might just cap it off. I will give it a go!
Pro Tips: When soldering a wet water supply pipe (for repair) ball up some loaf bread and stuff it into the pipe. Also, after sweating the pipe and while it is still nice and hot (right after applying the solder), brush on more flux to clean up the solder joint if you have made a mess of it. Not emphasized on this video: in order for the capillary action to work ideally, the heat from the torch should be applied to the fitting opposite of where the solder is applied (and well into the center of the fitting). This is to draw the solder into the joint effectively. Avoid contacting the flame with the solder!
If you use flux to clean the joint you risk cooling it too quickly which can cause it to fail. If you solder properly there shouldn’t be any cleaning required
i like your soldering video. Very clear and helpful and timely. Hoping to join copper tap tails on new Kitchen mixer tap to pipe work on the back wall but the sink is 3 inches proud of the wall because we had deeper worktops fitted. I hate flex hoses on taps, I want to replace it with all copper. First timer here. Thank you.
after ive taken the heat away i use the flux brush again to clean the joint while its still hot then use the wet rag to clean it down while warm and it makes the joint/solder super clean and easy to see, i check the joint with a little torch and a tiny dentist mirror to look for pinholes, has never let me down to this very day and i feel that extra confident to move on knowing that chances are there not going to be a leak, the worst thing is to do alot of soldering like when doing a full system and not be super sure as you move along cause if you do a system and fill it and you have a leak theres gonna be alot of work to back track on to find a leak
Great video, thanks. As a keen self builder, done all that you've shown, but nice to see the experts say the same. End feed always looks so nice and neat, especially with formed bends. PS. I always deburr the pipe inside :)
I'm a retired electrician/plumber (and never deburred) but am glad that you're a patient perfectionist. I always use wire wool pads to clean before and after although, I only use before soldering if the pipe is in an awkward place and I really don't want to go back and re solder it. Yes you're right, end feed are so neat when soldered correctly. I had a guy change my boiler a couple of years ago and his soldering was so good that you couldn't even see any solder on the end feed joints. I had to put my glasses on and shine a torch on the joints to just make out a very fine silver ring inside the joint. This guy was a master plumber. You often see plumbers cake solder all over the joint and pipe. I sometimes used solder ring joints for convenience or when I only had a couple of joints to make and they're not so bad. I also used compression fittings when cutting into the mains to fit a shower or washing machine as the pipes were often constantly wet and you also have a certain amount of adjustment with compression fittings, also you can easily turn an existing elbow into a tee joint. I must say that I've never used the new push fit plastic pipe and fittings so far (apart from old waste pipe fittings) and I feel that many builders have started to use the new push fit systems so they can fit kitchens and bathrooms without having any real plumbing skills. I've often come across their work under a bath, in an airing cupboard or in a loft. Just loads of unsupported un clipped spaghetti all over the place. Happy plumbing my friend.
@@alemgas No my friend. I had worked in electronics for some time and so I found electrics quite easy to get into as it's much simpler than electronics. So I was completely self taught and set up as a self employed electrician for about 4 years. There were no laws to stop you doing this back in the 70's 80's and 90's (and there still isn't now, apart from the part P tax} and my work was often passed by the MEB and MANWEB, when I worked in Wales and I was often complimented on my good workmanship. I sometimes worked on site contracts beside college trained electricians and I also worked for two quite big well known companies. Some of the workmanship from some of the so called trained electricians was appalling. Many of the sparky's just signed up to be an electrician on careers day at school and so that's what they ended up doing. But many of them didn't have a natural aptitude for the job. I feel that I did. So I got into plumbing because people were asking me if I could fit electric showers. So I fitted an electric shower in the house where I still lived with my parents. My dad did the plumbing and I did the wiring and it worked out fine. I then had a go at the plumbing myself and found that it was quite easy using compression joints. I Then bought a blow torch and experimented with solder ring joints in my garage and that was a massive game changer. The joints were so cheap and neat and they didn't leak. So I was now a plumber. I installed washing machines, kitchen sinks, bathrooms and outside taps. I also fitted gas cookers, fires and boilers. Some of the plumbers I worked with on building sites were qualified plumbers but also did gas work because it was basically just plumbing. We had the necessary gauges and test equipment to for leaks but of course, it wouldn't be enough these days as it seems that nothing can be done on a boiler these days without an hours worth of computing. So no my friend I am certainly not a dabbler. I was a carpenter when I left school in the early seventies and later did painting an decorating. I've also been a carpet fitter. I started work at the age of seventeen and retired at the age of 48 so I've crammed a lot in. Oh and yes I've seen many "electrician" dabblers along the way. Kitchen fitters are the worst who think they're electricians. They don't understand that when you reduce a cable size you need to fuse it accordingly. Thanks for your reply.
To add a bit of extra solder to a solder ring fitting is just daft, you may as well save some money & just use end feed fittings. A lot of my pipework is in chases behind tiles, feeding showers & basins so the low profile of copper end feed fittings is essential.
Thanks Roger. My dad taught me to always heat the pipework leading into the joint first and then move towards the fitting, and make sure you run the heat around the circumference of the fitting to ensure even heat.
Hi Chris I think copper is such a good conductor that it heats fairly evenly and quickly. If you mess around too long the flux evaporates so, in my opinion, just get on with it.
I worked for a local authority. We weren't allowed to use end feed on potable water only Yorkshire as it was guaranteed lead free solder. We went virtually all crimp for instance purposes.
As a DIY plumber I'm chuffed to learn that I've been doing it right all along but using the Yorkshire pre-soldered fittings. However, I apply far less flux, using my finger to apply the slightest trace of flux on all the surfaces. This means it doesn't run down the outside of the pipe and makes a much neater job. And I've never had a leak yet ... if you see what I mean.😉
Try the grey flux with added powdered solder. MUCH, much neater jobs and once the flux turns to silver (from grey), you apply the solder. It is thicker, so less ugly "spills".
I like your videos a lot. With this one I was checking if I was doing a good job these days, since I'm building myself a new central heating system with 2000l buffer tank. Cutting copper pipes and soldering is so rewarding. I had to fix one joint where copper to brass joint is screwed in to iron fitting and it was leaking, since I've put too little sealant string. I separated it in a minute with no problem, fixed the threaded joint and resoldered back together. If only it would be a bit cheaper. Copper pipes are really expensive.
Had a kitchen to replumb a while back. Plumber was there to fit some radiators. Said he didn’t have time to replumb it so I did it myself. He was watching me constantly and I ended up with a leak and he danced about the room 😂😂 ohh how I laughed a few days later when he had to come back for a leaking radiator
As a DIYer I ended up buying an expensive blow torch because the cheap one flared when upside down and the tip heated up and I burned myself. I also use a mirror to check that the solder has flowed all the way round.
I like to use scotch brite for cleaning, gets around all bends and into tight corners better. As for air pressure testing, especially on compression fittings, I’ve noticed it takes much less pressure than water to leak- thought that was interesting.
I’m a heating engineer by trade. Not bad on the soldering. But just a few things. you should start from the lowest joint and work your way up, never top down; when you get to the top joint the heat should be then hot enough to instantly feed your flux in with little heat. Also mapp gas is a pain in the arse for soldering, gets everything too hot too quickly, strongly suggest always soldering with propane on a gentle heat and take your time 👍🏻
What you say works in reverse, start from the top and the fux runs down. Then when you do the bottom you have only to apply a little heat and the solder will draw up. You can then remove the heat and avoid the solder runnning down the pipe. With your method the heat is still in the bottom when you do the top so it can run. Also Mapp gas is now just propane but they kept the name Mapp.
been a plumber for 40 odd years and remember being a bright eyed apprentice going into the plumbing merchant and always getting my professional plumbers magazine just to go to the end of it to read your joys of being a plumber,,,lol now i know
Solder comes from the same root word as solid. Solidus "solid", solidare "fasten together". It's the French that turned the Latin into soudur which is where I assume the American pronunciation came from. You can call it so'der if you like, just make sure your joint is so'id.
American here and I'm curious about the L getting dropped in our pronunciation too. I'd seem silly if I was the only local pronouncing the L so I just go with it.
As a fellow plumber I concur to leave the pipe well alone once soldered. What’s the point in using a wet rag to save yourself a minute or so, risking it leaking once you fill up? I saw a Polish plumber solder a joint three times in a row and each time it leaked, and each time he applied a wet rag seconds afterwards. I took over from there lol. Also I’ve been called out to repair corroded pipes which were no more than three years old, caked in flaky green old flux plumber too lazy to clean properly. With Yorkshire fittings what can happen is the solder can either drip out, or doesn’t look quite right when you can’t see a nice solder ring all the way around the fitting. So then you add more solder just to be sure, which kind of defeats the point of using them and at more expense. Also I always make a pencil mark the depth of the fitting, as frequently the pipe moves/gets knocked and you think it’s probably ok, but then you have to be 100% it is in properly. Having a pencil mark means you know for sure everything is ok.
I've always found those pipe cleaners/deburrers, the ones with the stiff wire heads, work well to start with but as they wear they make less contact with the pipe, and it's back to steel wool
I personally do prefer old fashioned copper pipe and soldered fittings, they have stood the test of time, unlike modern stuff. I also like to wipe round the joint with the flux brush while hot to wash the joint leaving it clean and shiny followed by a wet cloth to remove flux. Takes a bit longer but im no longer in it to make money, i only do stuff at home now, like James, I had enough years ago and went to work for somebody on a permanent site. 👌 Just a comment, the middle brach of the tee, the side facing the camera didn't seem to get the full solder flow.
Nice one Roger you got the job. I tend to start at bottom, heat rises and I play the flame onto the pipework first with a little flash of heat onto the fitting as the flux flows. Never had a joint leek in 50 years. Biggest soldered fitting would be 75mm Yorkshire in the winter. This took two blow torches and some solder and not just one fitting, thousands. My pet hate is uncleaned joints, very unprofessional.
, I am amazed when people tell me they have never had a leak, I have had loads over the years. I had one leak which was due to a hair in the flux brush coming loose. The best ones are where I forgot to solder a fitting and it held for ages. Do you debur?
@@SkillBuilder did this just last week! Soldered a 22 - 22 - 15mm tee. Totally forgot to solder the 15mm bit! I'm a painter and decorator by trade so maybe should stick to that in future! 😆
Great stuff Rodger,,, I'll be interested to see pressure test on pipework, it's something I haven't done yet but would save me alot of heart ache going forward.
Nice info on the set up. I was hoping you would talk about another key thing to understand and that is the science around heat and how the solder reacts to it to draw it into the connections.
Great video. When should we use MAPP gas then. I chose it so I could do big sizes and brass fittings (which were always a problem for me even with lead solder). Many thanks
@@SkillBuilder still called Mapp gas here in Ireland. sold everywhere, not cheap though, still it's the only bottle (with the Rothenberger super fire torch) that will work upside down. something that's very improtant, those stupid gas torches you buy in DIY stores can only work in the upright position. soldering under ideal conditions is one thing, soldering virtually standing on your head is something else, well you know what i mean...
@@SkillBuilder , MAPP was a trademark name representing methylacetylene-propadiene propane (48% methylacetylene, 23% of propadiene, and 27% of propane) having a flame temp of 5300 °F when mixed with oxygen or 3,670 °F when combusted with atmospheric air. Propane burns at 3,600 °F. MAP Pro gas (or any of those yellow cans) sold today is propylene (99.5%) and propane with a flame temperature of 3730 °F
I do my own plumbing. But it was nice to know how much solder to use on the none Yorkshire joint. I'll remember that. The good old bur or not to bebur the cut joint.
Hi Roger. Good video. I have been following your videos for some time, and always enjoy your content and help. Regards this video, i go back to the Eighties decade when i did a little DIY on my home copper pipes in Yorkshire and add solder joints. They turned out well, and i enjoyed the process. I am commenting today with a question for you. In Australia where i live, doing your own plumbing and electrical work is illegal for the general public. I think changing washers over is the limit for the general public here. What is the story over there in Great Britain regards the public doing their own plumbing work? Cheers, Greg.
@@jonh1808 doing your own electrical work is high-risk. and stupid really. all electrical work should be done by a qualified electrician. why risk a fire or even worse, somebody gettin' toasted....
Great video! Question: If I'm capping a pipe, how do i ensure no flux is left on the inside where I can't see it or clean it out with flowing water? Should I just make sure not to flux all the way to the pipe's end?
Flux is not as corrosive to copper as some people imagine. It is a worse problem in steel radiators where it lies in the bottom. I would not worry about a little bit in a dead leg
Interesting. I've always brazed copper pipes but I find I cannot get enough heat with the map gas torch on a 3/4 inch t piece fitting. I'll definitely be using solder now. Do you use resin cored solder?
You quote an example of residue flux eating through the pipes over 15 years.. It only takes 5-6 years to cause leaks if flux is not cleaned up - first hand experience of bad plumbing outcomes here.
Great video Roger. Doing up an old house at the minute and it has compression joints everywhere which have been there for about thirty years. Should I replace all of them with soldered joints?

Is it a case of using abrasive to remove the flux? Any other methods?

I air test section by section then I can put the floorboards down with the pipes under pressure. I can then reinstate the room and move on.
Wet rag is bad practice. Cools the pipe too quickly and messes things up.

I must say that I've never used the new push fit plastic pipe and fittings so far (apart from old waste pipe fittings) and I feel that many builders have started to use the new push fit systems so they can fit kitchens and bathrooms without having any real plumbing skills. I've often come across their work under a bath, in an airing cupboard or in a loft. Just loads of unsupported un clipped spaghetti all over the place. Happy plumbing my friend.
@@alemgas No my friend. I had worked in electronics for some time and so I found electrics quite easy to get into as it's much simpler than electronics. So I was completely self taught and set up as a self employed electrician for about 4 years. There were no laws to stop you doing this back in the 70's 80's and 90's (and there still isn't now, apart from the part P tax} and my work was often passed by the MEB and MANWEB, when I worked in Wales and I was often complimented on my good workmanship. I sometimes worked on site contracts beside college trained electricians and I also worked for two quite big well known companies. Some of the workmanship from some of the so called trained electricians was appalling. Many of the sparky's just signed up to be an electrician on careers day at school and so that's what they ended up doing. But many of them didn't have a natural aptitude for the job. I feel that I did.
So I got into plumbing because people were asking me if I could fit electric showers. So I fitted an electric shower in the house where I still lived with my parents. My dad did the plumbing and I did the wiring and it worked out fine. I then had a go at the plumbing myself and found that it was quite easy using compression joints. I Then bought a blow torch and experimented with solder ring joints in my garage and that was a massive game changer. The joints were so cheap and neat and they didn't leak. So I was now a plumber. I installed washing machines, kitchen sinks, bathrooms and outside taps. I also fitted gas cookers, fires and boilers. Some of the plumbers I worked with on building sites were qualified plumbers but also did gas work because it was basically just plumbing. We had the necessary gauges and test equipment to for leaks but of course, it wouldn't be enough these days as it seems that nothing can be done on a boiler these days without an hours worth of computing.
So no my friend I am certainly not a dabbler. I was a carpenter when I left school in the early seventies and later did painting an decorating. I've also been a carpet fitter. I started work at the age of seventeen and retired at the age of 48 so I've crammed a lot in. Oh and yes I've seen many "electrician" dabblers along the way. Kitchen fitters are the worst who think they're electricians. They don't understand that when you reduce a cable size you need to fuse it accordingly. Thanks for your reply.
@@truthseeker7794 Nice :)
@@seane6616 Thanks Sean. I'm just sipping a glass of newcastle Brown now. What's your line of work my friend.
i just couldnt believe you let that flux sit on your right hand the whole time. good video.
What is the problem? It is Laco not Everflux.
To add a bit of extra solder to a solder ring fitting is just daft, you may as well save some money & just use end feed fittings. A lot of my pipework is in chases behind tiles, feeding showers & basins so the low profile of copper end feed fittings is essential.
well done for this amazing video, thank you so much because it's very helpful to me thanks once again.
Thanks Roger. My dad taught me to always heat the pipework leading into the joint first and then move towards the fitting, and make sure you run the heat around the circumference of the fitting to ensure even heat.
Hi Chris
I think copper is such a good conductor that it heats fairly evenly and quickly. If you mess around too long the flux evaporates so, in my opinion, just get on with it.
I'd always heat at the centre of the fitting, not the pipe itself
I worked for a local authority. We weren't allowed to use end feed on potable water only Yorkshire as it was guaranteed lead free solder.
We went virtually all crimp for instance purposes.
The best videos on the internet. Al Gore invented the internet, you know. You know that, right?
Thanks for the good tips mate.
As a DIY plumber I'm chuffed to learn that I've been doing it right all along but using the Yorkshire pre-soldered fittings. However, I apply far less flux, using my finger to apply the slightest trace of flux on all the surfaces. This means it doesn't run down the outside of the pipe and makes a much neater job. And I've never had a leak yet ... if you see what I mean.😉
Interesting. I shall try that and if it doesn't work, I'll be coming for you. You tryna mess up my work???
i use my heat to burn/blow it away or just wipe it, solder should follow the heat into the fitting.
Try the grey flux with added powdered solder. MUCH, much neater jobs and once the flux turns to silver (from grey), you apply the solder. It is thicker, so less ugly "spills".
Try applying flux with finger splits, you only do it once! Tradies fingers always split during cold weather 😅
@@paulstokes393 Good point but my fingers split during the winter whatever. Super Glue to the rescue!
I like your videos a lot. With this one I was checking if I was doing a good job these days, since I'm building myself a new central heating system with 2000l buffer tank. Cutting copper pipes and soldering is so rewarding. I had to fix one joint where copper to brass joint is screwed in to iron fitting and it was leaking, since I've put too little sealant string. I separated it in a minute with no problem, fixed the threaded joint and resoldered back together. If only it would be a bit cheaper. Copper pipes are really expensive.
Clearly explained and demonstrated, good job!
Had a kitchen to replumb a while back. Plumber was there to fit some radiators. Said he didn’t have time to replumb it so I did it myself. He was watching me constantly and I ended up with a leak and he danced about the room 😂😂 ohh how I laughed a few days later when he had to come back for a leaking radiator
Thanks, good job explaining!
Great video Rodger, very useful
As a DIYer I ended up buying an expensive blow torch because the cheap one flared when upside down and the tip heated up and I burned myself. I also use a mirror to check that the solder has flowed all the way round.
I like to use scotch brite for cleaning, gets around all bends and into tight corners better. As for air pressure testing, especially on compression fittings, I’ve noticed it takes much less pressure than water to leak- thought that was interesting.
Simple and very understandable explanation. Thanks for the class
I’m a heating engineer by trade. Not bad on the soldering. But just a few things. you should start from the lowest joint and work your way up, never top down; when you get to the top joint the heat should be then hot enough to instantly feed your flux in with little heat. Also mapp gas is a pain in the arse for soldering, gets everything too hot too quickly, strongly suggest always soldering with propane on a gentle heat and take your time 👍🏻
What you say works in reverse, start from the top and the fux runs down. Then when you do the bottom you have only to apply a little heat and the solder will draw up. You can then remove the heat and avoid the solder runnning down the pipe. With your method the heat is still in the bottom when you do the top so it can run.
Also Mapp gas is now just propane but they kept the name Mapp.
That flux tool is rad, I want one!
Great video, as always from a great Channel 🙏🏻
Also very neat soldering roger
been a plumber for 40 odd years and remember being a bright eyed apprentice going into the plumbing merchant and always getting my professional plumbers magazine just to go to the end of it to read your joys of being a plumber,,,lol now i know
always blood , sweat and tea,,lol
Mint video, really useful. Thanks.
Solder comes from the same root word as solid. Solidus "solid", solidare "fasten together". It's the French that turned the Latin into soudur which is where I assume the American pronunciation came from. You can call it so'der if you like, just make sure your joint is so'id.
Honi soit qui mal y pense. Funny always thought ‘Mericans dropped the L to sod off…
American here and I'm curious about the L getting dropped in our pronunciation too. I'd seem silly if I was the only local pronouncing the L so I just go with it.
Don’t you mean the English pronunciation!?
@@paulfrost8952 No, we call it solder in England, not so'der.
@@petebateman143 mea culpa ah I thought you meant the Americans called it solder, as they seem to think they speak English🫢🫣
Excellent advice and tutorial as usual Roger.
Thanks 👍
Love you! 😂🥰
plumber parts I can't believe I called it plumber's parts
@@SkillBuilder ha! Everyone does! 😂🙈
As a fellow plumber I concur to leave the pipe well alone once soldered. What’s the point in using a wet rag to save yourself a minute or so, risking it leaking once you fill up? I saw a Polish plumber solder a joint three times in a row and each time it leaked, and each time he applied a wet rag seconds afterwards. I took over from there lol. Also I’ve been called out to repair corroded pipes which were no more than three years old, caked in flaky green old flux plumber too lazy to clean properly.
With Yorkshire fittings what can happen is the solder can either drip out, or doesn’t look quite right when you can’t see a nice solder ring all the way around the fitting. So then you add more solder just to be sure, which kind of defeats the point of using them and at more expense.
Also I always make a pencil mark the depth of the fitting, as frequently the pipe moves/gets knocked and you think it’s probably ok, but then you have to be 100% it is in properly. Having a pencil mark means you know for sure everything is ok.
I've always found those pipe cleaners/deburrers, the ones with the stiff wire heads, work well to start with but as they wear they make less contact with the pipe, and it's back to steel wool
You are right, though I don't like steel wool because it is bitty
Thank you for this masterclass. You are a Jedi master of pipework!
Very well explained, you're one of the best on TH-cam.
I personally do prefer old fashioned copper pipe and soldered fittings, they have stood the test of time, unlike modern stuff.
I also like to wipe round the joint with the flux brush while hot to wash the joint leaving it clean and shiny followed by a wet cloth to remove flux. Takes a bit longer but im no longer in it to make money, i only do stuff at home now, like James, I had enough years ago and went to work for somebody on a permanent site. 👌
Just a comment, the middle brach of the tee, the side facing the camera didn't seem to get the full solder flow.
Fantastic content 👌 👏 👍
Rodger master class is phenomenal! Thanks for making it available.
Nice one Roger you got the job. I tend to start at bottom, heat rises and I play the flame onto the pipework first with a little flash of heat onto the fitting as the flux flows. Never had a joint leek in 50 years. Biggest soldered fitting would be 75mm Yorkshire in the winter. This took two blow torches and some solder and not just one fitting, thousands. My pet hate is uncleaned joints, very unprofessional.
, I am amazed when people tell me they have never had a leak, I have had loads over the years. I had one leak which was due to a hair in the flux brush coming loose. The best ones are where I forgot to solder a fitting and it held for ages. Do you debur?
@@SkillBuilder did this just last week! Soldered a 22 - 22 - 15mm tee. Totally forgot to solder the 15mm bit! I'm a painter and decorator by trade so maybe should stick to that in future! 😆
@@SkillBuilder Why? it's all down to preparation. How many joints do you think I've done over the years?
I will only deber micro bore pipes for obvious reasons.
@@Martycycleman 2 joints thats why you've had no leaks! Or you've never been called back to sort any out because you sound like an arrogant c***.
Great stuff Rodger,,, I'll be interested to see pressure test on pipework, it's something I haven't done yet but would save me alot of heart ache going forward.
Excellent. Very helpful. Thanks. God bless.
Nice info on the set up. I was hoping you would talk about another key thing to understand and that is the science around heat and how the solder reacts to it to draw it into the connections.
Hi Jay
The trick with all these videos is not to overwhelm the viewer. Some people care about the science and others don't
When heating, should you heat the pipe or the fitting or a bit of both, for the solder to pull correctly?
Excellent training video thanks
induction? is that something one can use where "no open flame" rules?
Thanks, very helpful
Very nice video. How to solder and where to add heat when soldering a shut off valve that has nylon parts like nylon ball ?
Great film, thank you Roger. 👍👍👍
Great tutorial as always 👍
amazing skills
Great video. When should we use MAPP gas then. I chose it so I could do big sizes and brass fittings (which were always a problem for me even with lead solder). Many thanks
I am not sure MAPP gas is sold now. They kept the name but it is propane
@@SkillBuilder still called Mapp gas here in Ireland. sold everywhere, not cheap though, still it's the only bottle (with the Rothenberger super fire torch) that will work upside down. something that's very improtant, those stupid gas torches you buy in DIY stores can only work in the upright position. soldering under ideal conditions is one thing, soldering virtually standing on your head is something else, well you know what i mean...
@@SkillBuilder , MAPP was a trademark name representing methylacetylene-propadiene propane (48% methylacetylene, 23% of propadiene, and 27% of propane) having a flame temp of 5300 °F when mixed with oxygen or 3,670 °F when combusted with atmospheric air. Propane burns at 3,600 °F. MAP Pro gas (or any of those yellow cans) sold today is propylene (99.5%) and propane with a flame temperature of 3730 °F
@@JemicoTX So assuming my x2 yellow cylinders from a few years ago are real MAPP I'm going to have to relearn again. Thanks for the info
I do my own plumbing. But it was nice to know how much solder to use on the none Yorkshire joint. I'll remember that. The good old bur or not to bebur the cut joint.
Excellent presentation! Thank you!
Great tips Roger
Love copper . Those pre-solder are great (I double up and solder on edge ( belt & braces Roger lol )
Awesome vid mate. I'm about to attempt to fix a shower breach myself because my insurance company only covers the rendering & paint. Wish me luck.!
wow clean as hell. thank for this.
So you just have to touch the edge of the joint in one spot with the soldering wire and it will flow all around?
YES
@ Thanks
As a Yank, I have to apologize for what we have done to the King's English. We've made a right dog's meal of it! Thanks for the video, just the same 🙂
Hi Roger. Good video. I have been following your videos for some time, and always enjoy your content and help. Regards this video, i go back to the Eighties decade when i did a little DIY on my home copper pipes in Yorkshire and add solder joints. They turned out well, and i enjoyed the process. I am commenting today with a question for you.
In Australia where i live, doing your own plumbing and electrical work is illegal for the general public. I think changing washers over is the limit for the general public here. What is the story over there in Great Britain regards the public doing their own plumbing work? Cheers, Greg.
@@jonh1808 doing your own electrical work is high-risk. and stupid really. all electrical work should be done by a qualified electrician. why risk a fire or even worse, somebody gettin' toasted....
Great video! Question: If I'm capping a pipe, how do i ensure no flux is left on the inside where I can't see it or clean it out with flowing water? Should I just make sure not to flux all the way to the pipe's end?
Flux is not as corrosive to copper as some people imagine. It is a worse problem in steel radiators where it lies in the bottom. I would not worry about a little bit in a dead leg
Interesting. I've always brazed copper pipes but I find I cannot get enough heat with the map gas torch on a 3/4 inch t piece fitting. I'll definitely be using solder now. Do you use resin cored solder?
No not resin core just plumbers lead free and flux.
In the States a lot of plumbers call it "sweating" or like you mentioned "sottering" :)
That's great tips, cheers.
You know when you're on a job, what do you do to extract soldering fumes when you're in tight places?
I hold my breath
@@SkillBuilder LOL 😆😅
Seriously though, what do plumbers do, especially when you're using the leaded solder? 🤔
Excellent and to the point
Great video and great information
You quote an example of residue flux eating through the pipes over 15 years.. It only takes 5-6 years to cause leaks if flux is not cleaned up - first hand experience of bad plumbing outcomes here.
Great video Roger. Doing up an old house at the minute and it has compression joints everywhere which have been there for about thirty years. Should I replace all of them with soldered joints?
If they aren't leaking and you don't need to change them then leave them but if you need to run new pipes I would solder them.
First time seeing pre flux fittings before!
It is not genrally required because you get flux inside the pipe end. I just do it out of habit
Is it very common for a solder joint to fail later down the line?
