Turned mains off but hot tap is still running water

MoonMotorway · 03-11-2023 04:52PM #1

I need to replace the tap in the kitchen. There's a valve in the hot press to turn and that turns the water off from the mains. As far as I know.

I turned that. The cold water taps in the bathroom stopped. The hot taps still rain but the pressure was much lower.

However the water still ran in the kitchen. I need to replace the kitchen tap.

I looked under the sink for isolation valves but there are no isolation valves under the sink.

I found this connection over to the side and it's connection to the cold water pipe and also the dishwasher. Would this be an isolation valve? Do I need a special key or tool to turn it? If so, that should look after the cold but how about the hot?

If you have a cylinder in the hot press, post a picture of it.

There's a cylinder in the hot press but I am not at home right now to get a picture of it.

MoonMotorway · 03-11-2023 05:37PM

I'm not at home to take a picture of the cylinder but I know there are two more red levers located in the hot press. I don't know what they do.

It's under the sink in the kitchen, look harder.

It's the valve on the cold feed to cylinder. If you have trouble identifying the valve then the picture will help.

I always thought the mains valve was downstairs. Usually in the kitchen somewhere.

The mains will feed your kitchen cold tap, so if there's water still running from that tap , you haven't turned off the mains.

The mains will also feed your attic tank, which in turn feeds the hotpress.

The hotpress cylinder will feed the bathroom Taps (hot and cold,which is why you don't drink from the bathroom taps) and it will also feed the kitchen hot tap. So you need to turn the valve in the hotpress for the hot water supply to kitchen off.

The cold water supply comes from mains. So you need to turn two valves off.

If your kitchen is an extension your mains maybe in the spot the original kitchen sink was in ...that's where ours is.

I turned valves in the hotpress. The water in the bathroom stopped. The hot water in the kitchen stopped but the cold in the kitchen kept coming in with a strong flow. I let the water run for about 20 minutes too but still now reduction in the cold flow to the kitchen.

is there a water meter fitted outside the house ? If so, there will be a valve which controls the mains water to the kitchen

The cold water in the kitchen flows directly from the mains, not from the tank, so once you find and close the right valve, it will shut off immediately.

It is almost certainly under your sink and it should be something you can open/close by hand. Think the "look harder" advice above is correct.

I investigated under the sink. I can't find any value under the sink.

There is a water meter. What do I need to turn the water off there? Will a screwdriver work?

If it's conventional and good the two leavers in the hot press will be hot and cold isolation valves. The rising main isolation under the sink will cut off water to the cold sink tap and everything else, but it would need you to drain down the header and the hot water cylinder before the taps stop running. Switch off both the leavers in the hot press.

There might also be other isolators for the central heating.

This is under the sink. The pipe marked with an orange line is a waste water pipe. The other two is for hot and cold. The cold leads further up to a dishwasher valve. There's no valves lower down or above these pipes.

MoonMotorway · 07-11-2023 09:55AM

I am not able to get a good picture of the hotpress and tank.

You've the hotness end sorted out (hotwater stopped).

You will probably need to stop the cold at the meter. I'd take that opportunity to fit a valve beneath the sink, unless you can find your house isolation valve (if fitted) in the meantime.

Would I be able to pick up an isolation valve in any hardware shop? There's a small local hardware shop to me. I won't get a chance to get into any of the bigger hardware shops? Or will I order online for delivery hopefully this week. Should I hold off on work for another few days or will I keep trying to get a plumber (puke🤮). I rang many plumbers over the month and it's impossible to get one. I rang one plumber yesterday and he was due to phone me back in the evening and that was a lie. That was probably plumber number 6 at this stage.

MoonMotorway · 07-11-2023 10:37AM

By any chance is this what I am looking for, for installing an isolation valve under the sink.

No, it would work but they are for toilets and taps. What you want is a gate valve with a red ring handle.

MoonMotorway · 07-11-2023 10:46AM

Thank you for your reply

So something like this?

My copper pipes look flimsy. Will it hold something like this? What size do I get? I don't know what size fitting I have under the sink. I presume it's standard.

Do I need any other extra tools or rubber rings?

Would it be easy to install? Would it go on the pipe between the water in and the flexitail hose?

I feel this is a call a plumber tbh.

I'm very pro DIY. To a point.

For the tap replacement job or for adding and isolation valve or for both?

I cant get a plumber right now. I need to stop a leak from the tap. There's a person at home with no comprehension and won't minimise the use of the sink/tap.

Once I figure out how to stop the water in the kitchen, I would be somewhat ok going ahead with taking out the old tap and installing a new one.

I suppose I could stall on adding an isolation valve until I have a plumber.

Wearb · 07-11-2023 11:29AM

I'd agree that fitting a new isolation valve (I'd go for a quality lever valve) is best left to someone with experience. You'd have a flood if it gave way.

listermint · 07-11-2023 11:31AM

I think for all of it. You're unsure what fittings to use. Your unsure if the pipe will take a fitting that it's intended to be used on. You're having trouble locating how the house is fed and which source is for which part of the system.

Which leads me to think you may make fundamental mistakes in installing these fittings causing further issues.

I'm not trying to be mean. Just realistic plumbing may come across as easy. But it's not. Especially when there is water pouring on to a kitchen floor.

Replacing the tap should be fairly straight forward once I get the water turned off.

I am not trying to be stingy or save money by trying this myself. I cannot get a plumber. At this rate I will have to dip into nearby counties to try and get a plumber from somewhere else and with the way plumbers behave I will have to book as many as possible and see if one of them turns up to do this job.

I cannot get a plumber.

There is no saving money in what I am doing and the tools I am buying anyways.

I will forget about adding an isolation valve for now.

There is a water meter door in the ground on the road but I don't know if it's ours or the neighbours. It looks more likely the neighbours because it's located closer to them.

I can't find another door. I don't know if there's anything in the grass ditch.

MoonMotorway · 07-11-2023 01:38PM

I rang two more plumbers there and no luck. They are f*cking useless.

I need to figure out how to get the cold water to stop in my kitchen. There's definitely no isolation valves under the sink. I pulled the levered in the hotpress and I only managed to get the hot water to step. What am I doing wrong. Do I need to leave a tap running for a while and empty the tank? I am not able to climb into the attic if there's any work need to be done there.

I am not able to identify the meter outside and if it's the neighbours or not.

Wearb · 07-11-2023 03:15PM

"Do I need to leave a tap running for a while and empty the tank? "

No.

You already know how to stop the hot side.

Wearb · 07-11-2023 03:19PM

If you can't get a dedicated plumber for some of those small jobs, try some property maintainence companies, or handy man/woman.

MoonMotorway · 07-11-2023 03:25PM

The levers I turned in the hotpress were located up high in the hot press.

There is a pipe coming down from the tank in the hotpress. I wonder would it be this that would manage the kitchen water.

Further left to the lower picture, is a pump on the same pipeline. I would have presumed that would be boiler.

Turned mains off but hot tap is still running water
