Don't know how many people you've helped over the years mate, but I've watched so many of your videos.. I can't afford to pay someone to do these jobs for me, and when a pipe started leaking, I watched your videos and fixed the problems with a pipe cutter and some speedfit push on connectors. Thank you so much.
Saving the day 9 years on! Thank you- this is one of the best explanations I’ve came across. I couldn’t work out what people meant with bleed off. Now I know- averted a potential bathroom disaster with the hot feed lol :)
You have literally relieved my anxieties thanks so much. No emergency services in Dublin although advertising 24hr services. I'm in a new house thanks 😊
Thank you! The diagrams really helped me understand how it all works. And I was able to find the correct gate valve I needed to close. My landlord is unable to source a plumber here in Dublin to fix niggly little problems around the house, so I’ve had to learn how to do it myself.
Great video ! Hi Dereton 33, We have a conventional system and not a combi I have a hot water tap in the kitchen sink that is dripping slowly and needs a replacement washer cartridge. Luckily we have isolation valves, Can I use a flat head screwdriver to turn off the hot water isolation valve that is under the kitchen sink and replace the part ? Or do I still need to turn off the gate valve to shut the hot water off, ? Thankyou in advance Paul
gave me a better understanding, i will investigate mine a bit more closely as i have a tap under the sink and also one in the airing cupboard maybe 2 i cant remember now. i have low pressure up in the bathroom takes an age to fill could opening up these taps give me more pressure upstairs in the bathroom if i turn on the hot tap and the cold together its terrible just dribbles.
Hi I was just about to give up finding the hot water turn off as I needed to change my bathroom taps and phone a plumber when I came across your video.. Brilliant and thank you, I have another problem my oil fired central heating works great accept fir the water heating.. It doesn't.. Have you got anything I can try Regards Frankie.
Hi Al I live in a 1960’s block of flats. My partner and I can not locate the stopcock for our bathroom! Sure enough there is a stopcock underneath the kitchen sink which my partner turned off but apparently that only stops water to the kitchen and not the bathroom! After watching this vid I looked into the airing cupboard and there is a red gate valve with one end going into the water tank and the other end into a pipe going somewhere else. Is this the valve we’ve been searching for to stop water supply to our bathroom/toilet??? Thanks for your vids they’ve helped us out many times😃
Do i have to also turn off mains cold stopcock, if i have turned off gate valve that leads to the bottom of my hot water cylinder, want to change downstairs kitchen hot water tap, thx
Do you need to drain tank fully to turn off hot water to bathroom hot water tap or is it sufficient to turn off water supply to the cylinder and then turn on hot water tap until water stops flowing - is this a partial draining of the tank ? It would be good to cover three cases 1 turn off water supply to house 2. Turn off cold water supply to taps etc 3. Turn off hot water supply to taps 4. If turning off water affects the central heating system
@@dereton33 Thank you . I turned off valve between the attic tank and hot water cylinder , then ran hot tap in a second bathroom . Water flow from hot tap quickly reduced to trickle . So this may be be sufficient to be able to remove and repair the hot water tap in the main bathroom
Thanks for your help!!! Quick question if you have time. I'm looking to replace my kitchen sink. I plan to use the stopcock to prevent cold water running to cold kitchen tap. For the hot tap I'll need to turn off the cold supply to the hot water tank in the airing cupboard? After this, will I need to drain the hot water in the hot water cylinder through the hot tap in the kitchen or should the hot tap in the kitchen stop flowing automatically?
Hi, hopefully you are still on TH-cam as I know this video was some time ago now but these videos have been very helpful over the years. I do have a question however which relates to me installing a new bathroom. I want to replace the bath but there are no shut of valves to the hot and cold feeds. Is it a case of turning the water off at the mains/stop cock or will I need to turn off the hot water feed to a gate valve which controls the feed from the unvented cylinder in the airing cupboard? Any help greatly appreciated.
Hi there, this will be my first DIY attempt at changing a tap washer. Here's what I remember from when I used to help my dad. Turn off main valve (Stopcock) from outside front of lawn. Run taps. Unscrew tap and change washer. Replace tap with new washer and "bobs ya uncle' - DONE. Now I don't really think it will be that easy so could you please give me advice to stop it from being balls up. I'm also going to turn hotwater cylinder off - at switch.
Hi Mandy, there should be a stopcock under your sink, which will make it easier to turn the water off. Also do not drain the tank unless it is a hot tap you are fixing. As you have a hot water cylinder and roof tank, see if you can locate a gate valve in your airing cupboard to turn the hot water off. It is always better if you do not drain the roof tank as you can get airlocks afterwards. The tap repair is as you say, in your description.
Thank you for your reply - thats awesome. And thats a few more bits I would have definitely missed so I appreciate your help and will get up in that boiler cupboard and under the sink. Thanks again!
Thanks again for your help Al. So would I be draining the entire tank when I turn off the gate valve feed to the bottom of the cylinder to fix a stuck tap in the bathroom (which is on the same level as the tank) or should I be turning off the valve where the water exits the tank?
Hi, I want to replace taps and isolation valves on sink in upstairs bathroom. Would you just turn the mains off under the sink downstairs and turn the taps on the upstairs basin (the basin you are working on)?
@@dereton33 Hi, It is F & E, on the off chance the gate valves at the hot water cylinder in the press don't work, what would you do? Thanks in advance 👍
Thanks. I need to change the kitchen sink hotbtap washer. Set up is Like yours with gate valve in air cupbd. If i close this will the hot tank all need draining from taps first? How much roughly is this in litres? Thank you.
Can’t find a video on how to repair a leaking hot water tap in the bathroom . Old type plumbing with hot water tank and separate hot and cold taps . Water dripping from hot tap only . If I turn off water supply to the hot water cylinder and drain the hot water by running a hot water tap , will this affect the sealed central heating system ?
Try this one. th-cam.com/video/2RkoG1Di7OM/w-d-xo.html It shows kitchen tap but it will be the same process for bathroom taps. You can safely empty the tank it will not effect the heating system.
@@dereton33 Thank you . Unfortunately that video is for a cold water tap in the kitchen where the mains water is turned off under the kitchen sink . Mine is a different case . I have a hot water tap dripping in the bathroom . How to isolate the water supply in this case to the hot water tap and is the central heating affected in this case if the hot water supply is turned off and the cylinder drained ?
Hi, I'm changing my kitchen monobloc tap. I found where to turn off the cold water mains supply tap but I have a condensing boiler (Potterton Powermax HE with integrated hot water storage tank). There is no tank in the loft and the boiler is in the airing cupboard downstairs. There is one red gate valve in the cupboard on a pipe which feels cold, even when the heatings on. So, the question is: do I only have to turn off the cold water mains stopcock to stop both hot and cold water supply or do I need to turn the red gate valve as well? I have been reluctant to just turn it and see, in case I damage the boiler in some way. Also do I have to turn the boiler off as well? Thanks.
Once the valve feeding the hot water cylinder is turned off the water from all the hot taps will be off. There will be a small amount in the pipes to drain when it is first turned off.
I need to replace my hot water tap but my gate valve is very old and I’m worried it might start leaking.would it be possible to turn the main water supply off from outside and just run the hot until it’s empty? Thanks
hi nice video. I have found the stopcock and its fully off, the cold water is off and i have checked all of the pipe under the sink and all the way to the stopclock but stil the hot water tap is running. there was valve to turn but its on the cold water pipe and i cant see any on the other pipe. I,m now stuck as to what to do ?
So if I want to change the taps on the sink & mixer taps on the bath, I have to let the system tank drain out after turning the hot water supply off? Annoyingly, there's no isolation valves on the pipework.
I've got two red handled taps in my airing cupboard, one turns easily and the other seems stuck. The one I think feeds the cold water into the hot water tank, when closed, does not stop the hot water flowing. I waited for about a minute for the hot water to stop, but no luck. Can you think of a reason why this is the case? Also, the reason for this is I need to replace the valve in the cold mixer tap in the kitchen. If I don't shut off the hot water, will be changing the cold valve mean I'll have a big hot water leak? Cheers J
hey i live in a old 1960s trailer i cant find a shut off valve for the hot water to kitchen sink and it leaks bad where would i find a shut off valve only for kitchen sink , should i start looking around the water heater?
Hi, so ive always been curious. i have 2 stopcocks 1 under the sink (like always) and i have another in my bathroom in the top corner. ive closed it off and the toilet still flushes. just curious if you have any idea what it could be used for? and is it worth just keeping it closed? thanks Ps i like in a block of flats if that has anything to do with it.
Very good demo, love the drawings! However, I am struggling to find the way to shut off the hot water on a Megaflow HE SystemFit pre-plumbed unvented water heater. If I turn off the cold feed to it the cold taps and wc's stop flowing but the hot taps keep running. Do I just have to wait until the whole system is empty in this case? (This is in a ground floor flat )
@@dereton33 thank you, I’ve also watch your videos about the low water pressure with hot water. Do you have a video removing the pipe connected to the emotion and water tank as I can’t afford a plumber?
I just had Thermostic Shower put in and hot water keeps running hot and cold and the hot tap in sink does the same and in Kitchen. We have a Combi do you have an idea what's causing this?
Thanks for your great content! I need to change a kitchen hot water tap & unfortunately it doesn't have a means of isolation on the pipework. I have found some gate valves in the loft next to the cold water storage tank, if i isolate the valves in order to stop the hot water do i need to do anything to prevent damage to the boiler or booster pump. The boiler is in an airing cupboard with a hot water cylinder below it. Thanks in advance!
Great vids! Quick question if i want to change a hot tap downstairs and want to isolate it i just close the cold feed to the bottom of the hot water tank and open the hot taps for a few minutes?
+dereton33 Ok i was under the impression that i'd have to drain the whole water tank but this isn;t so apparemtly as the hot feed is at the top of the tank. Any way to avoid airlocks?
I think I have the Cold Feed System which I worked out looking at your pretty good diagrams incidentally, I find it takes ages to turn the hot water off after closing a gate valve. However I was wondering if I put a normal stop valve on the copper pipe that comes out the top of the hot water cylinder, then I could turn off hot water instantly without draining the cylinder itself. Is this safe to do and why fo typical systems not have a stop valve on this out pipe already?
@@dereton33 Thanks bro, I looked all over the net and never noticed one on the others so assumed it shouldn't be there. I guess I'll have to drain the entire hot water tank before embarking on any job with hot water taps

Great video - one question...am about to replace my kitchen mixer tap for the first time with a new kitchen mixer tap - so from what I have googled - I know to turn off the combi-boiler, turn off the stopcock, and turn the 2 screws on the hot and cold pipes (of that kitchen sink) from "vertical" to "horizontal" - but if I do all that, do I still need to turn all the "individual flow-controls" to OFF on various things, like upstairs bath, bathroom sink, bathroom toilet, etc? Or does doing what I listed before that suffice? Thanks from London :-)

Make sure all taps are open fully, but low pressure in the bathroom is usually because the supply is fed from a roof tank.

Hi I live in a 4 bedroom house building 1957 UK my water pressure of hot water is too high about 60° I would like to decrease The Hotness of water can you tell me how do I do that
Turn down the stat on your tank.
wish you lived by me,dereton .iam trying to change my hot waterbath tap.ive tured the gate valve of going in to my cylinder,and allso every stop cock valve in and around cylinder all so the main cold valve . but the hot walter is still coming out slowly,for a bout 1hrs now dosent seem to be stopping,will it stop eventually and how long ,please. i cant wait to fix this bloody hot top,done the cold one about 2hs ago
The gate valve is letting by. Best now to turn the mains back off, turn the gate valve on. Then run the hot tap until it completely stops.
Great video - one question...am about to replace my kitchen mixer tap for the first time with a new kitchen mixer tap - so from what I have googled -
I know to turn off the combi-boiler, turn off the stopcock, and turn the 2 screws on the hot and cold pipes (of that kitchen sink) from "vertical" to "horizontal"
- but if I do all that, do I still need to turn all the "individual flow-controls" to OFF on various things, like upstairs bath, bathroom sink, bathroom toilet, etc?
Or does doing what I listed before that suffice? Thanks from London :-)
You only need to turn the screws on the vertical pipes ( ballafix valves) to horizontal position, nothing else.
Many thanks for such a quick and welcome reply 🙂
How to turn off heat water to hot water tap in the bathroom . I have a dripping hot water tap . What is best way to repair it ? Do you have a video on this subject ?
Depends if you have an F and E system or a combi boiler. I have lots of videos on tap repairs. Check out my channel.
@@dereton33 great thanks . I will check out the videos . Great videos by the way !
@@dereton33 No combi boiler . Hot water tank . No valve under theE sink . Do I turn off supply to hot water tank and then drain the tank by turning on hot water tap ? Any need to re-pressure central heating after doing this ?
Went to replace kitchen sink tap in my new house (built 2003) couldn't work out how to isolate hot, isolated stopcock under sink, ran taps downstairs until flow was zero. Took existing tap apart, lastly taking off hot water pipe annnnnnd.... Drenched???? Wtf... I changed upstairs shower unit doing exact same and no water came out hot or cold. Anyone reading this, especially OP as this is a great wee video with any ideas/advice?
There are two outlet pipes from hot water tank with iso valves, but they seem to be for radiators.
Helllllllllllpppppppp for future plz. Cheers in advance.
Drain the hot tank. Turn off the mains and run the hot water tap until it stops running.
Thanks Al. But I have always wondered why the gate valve for the hot water is on the input to the tank only and not to both input and output.
No problem Tom.
I have a blue plastic tap with a red button on it, in a cupboard near my kitchen sink.
Is it a stopcock and what's the red button for?
I would need to see a picture of it.
dereton33 hi, thanks for your reply. Here is a link to a video of it. th-cam.com/video/rhhGv1m9Al8/w-d-xo.html
It is the main stopcock, with a locking red push button. Thanks for the video.
Great video and advice as always, keep them coming 👍🏻
Thanks 👍
Very helpful. Thank you.
A work man turned the water off in my mothers house then asked my elderly mother to go up stairs and turn all the taps on. Is there any reason why you would do this? I’m just worried that she was being tricked in some way.
Only if he needed to repair a hot tap or a leaking pipe on the hot feed pipe.
If it is a Combi can you just turn the main off?
Yes Paul.
Perfect! Good man .
No problem.
Great advice! Thanks
No problem.
You have an earring cupboard? Fancy!
Airing
@@dereton33 just a joke brother
Great help .Thanks

In case of a seized under sink main water tap just heat it up with a blow torch for 15-20 seconds and it will loosen up and turn.
Dont burn the house down though.
If changing hot tap in bathroom do I close gate valve in aring cupboard
Yes. If it does not work then drain the tank.
