How to install water stopcock for toilet cistern

illusionek

Hello

Ive got a leaking toilet. The plumber is coming in couple days time but in the meantime I would like to minimize water damage. The current stopcock shuts off water for the whole bathroom and I was wondering if there is an easy way to fit one only for the toilet? I am not great at DIY but would like to give it a go if someone could guide me.

I was thinking to buy below pushfit stopcock

Below are photos of water connection and inlet of my cistern and I am hoping it would be as easy as replacing the black connector with the above.

Just about any 15mm ball shut off valve will do, push fits are easier but a compression will also work on plastic.

The black connector is part of the stainless steel hose that goes to the screw fitting underneath the cistern, i.e. you can't just swap it.



I'd go for one of these to sort things out:

1. Turn off the water, flush the toilet.
2. Get a carwashing sponge, old towel or something similar to catch any water in the pipe.
3. Unscrew the stainless steel hose from under the cistern.
4. Screw one end of the service valve to the cistern - only one end will fit.
5. Take the nut off the other end of the service valve and remove the brass olive which isn't needed.
6. Screw the stainless steel hose on to the service valve.
7. Cross fingers!
8. Turn on water and check for leaks.
9. Open service valve if it isn't already opened.

Someone may suggest a better way, but this should work and be fairly easy.

Just mend it.
Put up a photo of the inside of the WC system.

Hi - not meaning to contradict you or be clever, but isn't this assuming that the leak is from the fill valve? Of course, if it is this would be the way to go. But the OP refers to the possibility of water damage as a result of a leak from the toilet which could be a cracked cistern, the pipe between the cistern and the bowl, etc.? Is there something in the photos that makes you think the fill valve is leaking or are you just assuming that because it is the most likely cause?

Plumbing is fairly easy to learn, including fixing & replacing ballcocks.

The only time I have ever paid a plumber was for connecting up gas & that was purely for legal reasons.


However, fitting a stopcock is no easier than repairing the ballcock (fill valve) yourself. So I suggest replacing that yourself. Assuming that this not shutting off is your problem.



I presume it is adjusted correctly so the water level is below the overflow ?

Flexi hose with isolation valve would be easiest. Adding just an isolation vale would need an extra piece of pipe which I assume you don't have. The Black connector you have may need a tool to remove it.


How bad is the leak? Towels and bowls might be easier.

Turn off water, flush cistern, take flexi hose push fit off at wall/tiled end.

Unscrew at cistern end, Fit one of these, you get different lengths so measure first.

Tighten all up.


Or get plumber to fit whilst there.


What/where is it exactly leaking?
