People like you make the world a better place! Not only do you make videos to help thousands of us on TH-cam, you are also are a great neighbor! Thank you very much for the helpful video. Always a thumbs up!!
Thanks for the really nice comment! I'm always helping others, just the way I am. I'm lucky to have a very nice neighbor, some people have nightmare neighbors. We can sure use many more people like you on YT as well, you put a lot of effort into your videos to help people make the right decisions. Can't wait to see more Farmabago videos! LOL
It's actually a condemnation of modernity that his kindness in helping his neighbor is even remarkable. I remember when I was growing up, my father was always either helping or getting help from neighbors for various projects.
In today's world, you are lucky if you know your neighbor's name!
Woah. Apparently i found your neighbor. He is awesome. You are also awesome, Project Farm. Love your videos
Saved my butt with your video. I was replacing my daughter's 24 year old hot water heater and ran into the old PVC being expanded and the couplers wouldn't fit. I was ready to call a plumber and eat crow but decided to Google a resolution. Kudos to you!!! Picked up a heat gun and I was back in business! ❤
Oh to live in a climate where your well pump could reside outdoors! Such a Good Neighbor you are !
😀 Thanks for watching!
Your a genius. I have a 2500 gallon water tank and irrigation pump that broke at a PVC joint on the suction side. After cutting away the broken pipe the new 2 inch couplers would not fit. Your heat gun and soap trick helped me fix it in under an hour. I plan to leak test tomorrow after I let the glue set for 24 hours. Thank you so much.
Giving a thumbs up for helping a neighbor! I don't mean to knit pick, but I've been gluing PVC for over fourty years and was taught by the best at a very young age. When you twist the pipe after the glue, you should ALWAYS only twist in one direction,
about a 1/4 turn or better, not back and forth. I'm not going to bother explaining why, but let's just say it makes for a much stronger bond. I was also taught, and have always done so, when you are coupling two sides, you should glue both ends at the same time, then turn the pipe (in one direction only) between the two joints. That way, both connections get a twist, not just one end. Nice tip on the oversize pipe scenario...👍
I've been doing it that way since 1989, never any problem. One thing about PVC, if it's clean, when it's glued together, it never leaks. Thanks for watching!
Manufacturers recommended procedure, which is probably found on the can.
8. Push pipe FULLY into fitting using a ¼ turning motion until pipe bottoms
I'd also like to say that heating and bending pvc water lines are not in compliance with plumbing code or the manufacturers spec. Should have probably cut that pipe somewhere back beyond that 90 to a place that would allow a fitting to go on correctly.
And what's the point in talking about primer and inspections when it's obviously not getting inspected. I've heard that all sorts of plumbing is gotten away with in FL.
I'm from Wilmington NC, one of the strictest counties in the USA for inspections. I had to be a grade A student to make it. After years so trusty that I could pass an inspection on reputation alone... They practically write the international code from there.
Anyways good vid, and thanks!. Now that I'm out of construction and onto being a service tech $$$, this info may come in handy as a last resort for a temporary repair...
@Ryan Cook If the PVC pipe manufacturers can heat and flare the ends of the pipe, so can I, no difference. If I cut it further back, then end up with the same larger pipe, then I gave myself more work. As for the twisting, how exactly do you plan on twisting a 90 deg elbow when installing it? :-) Lastly, there's nothing temporary about the repair.
@@electronicsNmore I'm just a technical person, I have to be, there are specs and codes. So if the manufacturer must use hundreds of thousands of dollars worth of equipment and scientific engineering to mold PVC, it's ok for you to use a blow dryer, even though it goes against mnfg spec and the plumbing code. Ok... As far as cutting the pipe back to just under the ground, level, or just above, I am positive the fitting will go on correctly, and save you the time you spent heating up the fitting and destroying it's integrity. I could have made this repair in five minutes, and correctly by all standards. About glueing 90's onto pipe, simple, you dry fit a piece on the other end, glue the 90 on, give it a 1/4 turn until aesthetically straight shown by your dry fit piece, I do it all the time. Are you an electrician by trade and experience?
@@HVACLife it's not religious or obsessive, it's just the rules. It's not arguing over a particular way of doing things, it's letting the rules be known. There are many ways to do things correctly. Where I come from the code and mnfg spec are highly enforced, one could even fail an inspection for being a few inches to long on their hanger spacing. The rules are the rules, there's a correct way to do things and an incorrect way. It's not about what could work for a time. That's all. I still appreciate the video and may incorporate this technique one day as an emergency temporary repair.
Had a new replacement pvc toilet flange a bit tight over the existing pipe. This trick worked like a charm, perfect fit. Thanks for making this video!
Thank you for sharing, you never know when you have to make adjustments out of the norm. Yes, I understand a 1/4 turn is recommended, but it’s not the end of the world if you don’t. We are here to help each other and try to learn from one another. Thanks for sharing!
Have never run into this with years of repairing old things, but in the event of needing to know this, you my man, have saved me a lot of frustration!!! Thank you, and I try to be that same type of neighbor
Thanks for watching! Be sure to look over my very wide range of videos and share.
Did irrigation work for twenty years. Something wrong here. Wonder if he was using sewer coupling instead of pressure coupling. Have put together many miles of pipe and never ran into what he describes. Also wreaked that coupler by heating it like that.
You are BLOODY BRILLIANT! Obviously I had the same thought hence the search for this topic but thank you for your confirmation!!
I have been to my local Bunnings in Australia 3 times, every time sent home with the wrong pieces despite showing them the measurements required. Im not going back, Im doing it my way :). Thank you so much :)
Replacing an old water filter that sprung a leak. Cut the pvc pipes went to slide on the coupling and bam no amount of force was gonna slide I on. Kinda felt like I was standing in the middle of the road with no clothes on..LOL..
And your video came along and saved the day...THANKS!!!
Thank you so much for this! It is exactly what I needed when the shower pipe broke. I wasn't going to have water until I could cap it off and the caps would not go on. And thanks for being such a good guy, what I wouldn't give for a neighbor like you!

Awesome video! Saved me so much time repairing the PVC break. Thank you!
Great video, had a similar issue, also on the suction piping to my well pump. Reading the comments here is good for a laugh too, 500 "Why not buy the right fitting next time?" yet not ONE of them actually says what that magic fitting is.
Thats why I am watching this channel. Sometimes something elaborate and sometimes just everyday routine problem solving.

A neighbour like you is a blessing ...
Thank you. 😊 Be sure to watch my video today at 5pm, it's educational and hilarious.
This worked perfectly for me with a TOTO wall mount toilet elbow that was not compatible. Thanks much!
A heart of gold you have. God bless you..
Thanks for the kind words!
Outstanding idea ! I was looking around for someone who could precision lath the inside of a coupler. I will give this a try. The pipe in the ground is 40 yr old thin wall 3" pvc and there are no couplers available anywhere I have searched. Doing this with a 3" sked 40 coupler should work. I had not thought about heating up the coupler. Fingers crossed ! Just a follow up a little later from commenting, it worked ! Boy, am I happy, thanks again for the tip !
Glad I could help! Be sure to check out my PVC tips and tricks video playlist as well.
Only issue I see with installation is the lack of unions for ease of pump removal later on. Nice solution to larger pipe problem!
Another one of your great commonsense fixes, Doug! Thanks for sharing & Happy New Year.
Thanks, and same to you!
Going through this issue now. Was a bit puzzled as I buy all of my fittings from the same hardware store and just ran into this. I thought maybe with the Artic blast here in Texas back in late Feb, that "new" manufacturers surfaced creating the issue. I will definitely use this method. Thanks for sharing

Never used heat to stretch a fitting. I have used heat to pull broken pipe out of a fitting. Thanks for the tip.
That itself is a great tip!

Thanks for watching!
Great demo!!
I wish I knew about heating to make joint fit before now! Thanks!
It’s crazy how often I come across oversized PVC. Back in the late 70’s to early 80’s apparently the different manufacturers all had the same ID but to prevent different brand fittings and pipes from being used they changed their OD just ever so slightly. I work for a large water utility company. We end up having to use Bolted Couplings to connect our copper or brass pipe to their private lines.
This by far gives a cleaner appearance. When we are done my work all get buried. Great video and great tip.

Thanks for watching Paul!
I very much appreciate your share of knowledge thx
You're welcome! Be sure to share.
If you have cracks or holes you can soak pvc with the glue softening it . Then take your fingers pinch it closed like clay. It re hardens in a few hours strong as new.
I fixed SDR sewage pipes in ground this way for years.
Excellent work Thanks
Interesting idea! Thanks for watching
@Aamir Tariq yes it take s several application s of glue on crack then pinch softened pvc together it will reharden.
@Aamir Tariq the glue heats the pipe therefore softening it

Another tip for a solid glue connection is to debur the ends of the pipe after it's cut. If not the ridge left after cutting will just push the glue into the fitting when the pipe is pushed in. Like a syringe. You don't want that syringe effect.
Very helpful Thanks👍
Thanks for watching!
Thanks, you have very helpful videos. PVC does get brittle after a while, probably from the UV from the sun, I can see that happening. This is good to know, in case I ever run into that situation.
Yes, it gets very brittle. Thanks for watching Pete!
@@electronicsNmore I was recently impressed by ceramic brake caliper paint from an Advance auto parts store. About $10 for a large spray can, and after inspection it would block sunlight from damaging the pvc. This paint covers well- a little goes a long way.
Use schedule 80 above ground
Well done great job 👍🏻

Any thoughts what you’d do if the pipe is smaller than the fitting? I have a pool drain pipe that’s just slightly smaller than a 3 inch pvc I need to repair. Thank you!
Very nice fix
Thank you Ed!
Great video.
Thanks! Please share.
Thank you
You're welcome!
Never had this problem before but good to know what to do if it ever happens. Thanks.
You're welcome! Be sure to share the link. Thanks
Very nice fix. Maybe could have put a union there to allow for easy uninstallation if necessary. Many Thanks
Hi there. If PVC, it's much cheaper to just cut the pipe and use a coupling. If the pipes are all galvanized, a union is definitely the way to go. Thanks for watching!
I'm installing a drain pipe in my yard. French drain from retaining wall to a channel by back porch. Then I need to connect a PVC pipe or some type of hose that is smaller in size to go through a backwall fitting. It barely rains in Phoenix but, since ground is hard, when it does my backyard floods and water sits for several days. So , since it doesnt rain a lot I'm not concerned about the smaller pipe not keeping up with water filling drains.
You can also sand both pieces I build swimming pools and have used this truck and also sanded as well sometimes the heat makes the PVC brittle after it cools good video sir 👍
The size difference was too much to sand. I never noticed the heat making the PVC brittle, but UV light definitely makes it break much easier over time. Thanks for watching!
Genius!!
Glad you enjoyed my video. Please share the link. Thank you!
Nice idea! used it to join 8mm hose with a 5mm one.
They could hardly fit inside but barely managed to push far enough to secure fit.
after watching your video, I heat them up a bit with a lighter and it slided in perfectly easy!
Thanks!

Can you do this if the PVC is threaded? For example, I need a pvc adaptor of 1-3/4 but can only find 2" or 1-1/2. Which would should I get?
Nice work neighbor1
Thanks Rick!
Nice
Thanks for watching Dan!
Can I use hairblower? :D great idea btw, I have exactly the same problem
FYI if you don't have a heat gun, you can stick a piece of PVC, or plastic conduit in the exhaust pipe of your truck with a rag as a gasket to force the exhaust through the pipe and it will get soft so you can bend it all around.
Not too fond of that idea, use rapidly boiling water.
@@electronicsNmore where are you going to find a pot of boiling water big enough to put a whole stick of conduit in? I'm not talking about stretching a coupling, I'm talking about odd shapes you want to contour
Is this method. For / a pvc pipe that expanded over the years ?????

Is the size difference due to one being PVC and the other being CPVC? The water supply lines in my house are CPVC and I found out the hard way that, for reasons that are beyond me, the sizes of that and regular PVC differ despite having the same marked size.
I thinks it's due to many years of pressure and heating from the Florida sun. I'd expect the same thing to happen in Nevada and Arizona.
cool

I guess Florida is the only place this could happen? Very convenient that it was all easy to get to.
No. Anywhere in the southern part of the USA, where the pump is outside. In freeze prone areas, the pump is usually in a room.
Oh. I thought other places in the South got below freezing often enough to make outdoor water pumps too prone to freezing to be outside. Thanks.

You can do this to make a "hub" or "bell" end if you don't have a coupling as well. Saves a trip to the store.
I have videos demonstrating that. :-)

@@electronicsNmore Oh cool. This vid showed up in my recommended vids. I'll have to subscribe and check out the rest of your videos. People posting stuff like this is what makes TH-cam so great.
Also,u made me think, how's heating up the pipe and putting a 1-1/4" flaring tool inside the pipe,to make it into a coupling
You can stick the coupler in the exhaust of a diesel equipment motor like a skid steer and it does the same thing. We take the same diameter pipes and heat them and shape them over their own caliber pipe which is what they do with one end if them anyway at the factory
You mean a tailpipe expander?
@@electronicsNmore no you just slide it over the pipe and it expands on its own it's really soft stuff you leave it on there and it hardens in the shape of one
Just did this earlier today and then saw this video.
Thanks for watching Ben! Be sure to rate thumbs up and share.
You can also use this method to connect 1/2" sched-40 PVC to 3/4" sched-40 PVC without a coupling if necessary.
Yes
why was the existing pipe too large? never seen that with stuff from the 1970s up until today. Was it actually 1-1/2" (probably not, that would be a lot larger)? Was it a non-standard pipe to begin with? (not Iron Pipe Size (IPS)?) Very strange...
Since the stretch-n-form worked, the old pipe must have been fairly uniformly too large, but why?
I've seen it happen at least 4 or 5 times over the past 30 years. Could be heat or UV related. Thanks for watching!
@@EDesigns_FL As long as it is standard pipe using standard IPS sizes, the different schedules are all the same outer diameter. The wall thickness changes, changing the inner open diameter. Doesn't matter if it is class 125, class 200, schedule 20, 40 or 80. All IPS sizes maintain the same outside diameter and can use the same fittings.
@@EDesigns_FL I wondered if somehow CPVC was involved in that system but the color sure looked like normal PVC (vs the yellowish CPVC).
The only PIP brand I know of is NAPCO, and their PIP starts at 6in and goes up from there! (I have a mix of 8in and 10in NAPCO, and some "gated" in 6in and up that may be a different brand. I don't know if any of it is IPS compatible or not.. my IPS experience ends at 4in nominal.)
@@EDesigns_FL The O.D. doesn't change on a PVC pipe, the I.D. does. If the O.D. changed by schedule, you'd have to change fittings as well.
We use a mapp gas torch the same you use for soldering it's an old trick you can also join pipe to pipe if you have no fittings

Nice video. Who else spotted the frog at the 8:10 mark?
I see no frog. LOL
@@electronicsNmore Look at the top edge of the pot. Now I see that is probably your foot. Lol.
What have you seen of tests using solvent without primer with pvc joints/junctures on constant pressure systems?
th-cam.com/video/1o4E2pdEv-s/w-d-xo.html
@@electronicsNmore I saw that, and, apparently there's no practical justification to use primer, - that primer doesn't make a useful difference, at least in the 1/2 to 1'' range of PVC pipe.
I had this exact problem! Neither sanding nor any combination of swear words helped, but heating hopefully will!
It's fairly common. Worst case you can cut the pipe way back and it should be OK.
There's gotta be cement and primer inside tbe pipe. Does that not leak into the tap water?
You always get some primer/cement inside the pipe. It dries fairly quick, and what doesn't dry, turns to a white looking thin plastic when water comes into contact. You always flush the system after doing repairs. This well is used for lawn watering. Thanks for watching!
Nice job showing this, done it many times, but next time! put something down so not to stain bricks/concrete or what ever is below
No need to, I flipped over the brick, they were just laying there. If it was a nice clean concrete pad, then yes, lay down a rag or piece of heavy cardboard. Thanks for watching!
UV from the sun degrades the PVC and makes it brittle like that. Painting new PVC that will be exposed to the sun will extend it's life.
Can I come and live next to you?
Me too
Don't forget to sand every end of the pipe or the inside if you are fitting gives better bond whit the glue
Can you do this on both sides if you needed too?
Yes
Awesome hack but honestly not everyone has a heat gun. Is there any other way to do this just in case? Of coarse without having to buy a reducer fitting.
You can also heat the fitting in vigorous boiling water, or in a small toaster oven set at a MAX temp of 250 Deg F. A temp of 225F is ideal.
@@electronicsNmore Niiiice! 🤜🤛
Does this affect the long-term integrity of the pvc at all?
No
You should mark the 6” pipe to allow you to check it was fully inserted in to each fitting.
It was fine, every little bit of PVC pipe doesn't have to slide in for the connection to be strong. It's extremely rare for me to have a PVC solvent welded connection leak. Thanks for watching!
Think you can do this with a shallow pot of hot water inlue of heat gun. Good advice still.
Yes, but it doesn't get as flexible as the heat gun. The fitting gets more "rubbery" with the heat gun. Thanks for watching!
why no union coupling joint?
(this is not a bash, just wanna know your wisdom on the above project)
Hello. There was no reason to spend the extra money because the cast iron pump housing is very well made, and we normally replace only the motor. The motor simply unbolts. Thanks for watching!
So if they are the same size, why didn't it fit. Was it a difference in manufacturers, was it metric and SAE. Shouldn't all manufacturers have same dimensions and standards. Would the heating alter and weaken the molecular integrity of the plastic.
Good video, thanks for sharing.
Why don’t we see size mismatches with galvanized and copper pipe? If 2 pieces are the same trade size, why don’t they fit? Please explain Bobby.
@Rodolfo Gomez. I think it's due to years of pressure and heat. As for heating the plastic, the factory heats the plastic exactly the way I did to create slip ends on 10 foot sections of PVC pipe.
Is the difference because the larger pipe is made for high pressure and the coupling for waste pipe ( low pressure ) , in the uk we have slightly different sizes so the two can't be mixed up
No, both SCH 40.
How'd it turn 🔵
Just fine. Thanks for watching!
