Flushing toilet makes a loud noise

[Mike-H]

When I flush the toilet there is a loud groaning noise. It sometimes sounds like a steam boat has pulled into the bathroom If I turn the sink cold tap on after flushing the sound increases.

I’m sure it is something easily fixed but I can not see what is causing the problem.

Thanks, Mike.

Hi Mike.

It's probably caused by an old diaphram washer in your valve, vibrating just as the valve closes.
Turn the water off.
Strip down valve, taking note how to reassemble.
Replace diaphram washer (usually a round black disc).
Reassemble.

Simples.

or fit a new valve which you may find quicker and easier

Later, you can repair the old one at your leisure on the kitchen table, as a spare, if you want, but they are not expensive.

Thanks for the advice. Sounds like I need to do some graft then.

Yup about 5 mins work, such a graft

[Mike-H]

Are all valves the same?

So i'm lazy, shoot me plus I will need to take the damn thing out find a replacement and refit. Now if i only lived near the local plumbing merchant life would be so much easier.

looks a bit like this-

If that is the right height then i'm sorted. If not they do an adjustable one

for £4 i think I'll just get a new valve. credit crunch... whats that?

[seco services]

i prefer these better.

Do they work with ball cistern? They do not have the arm that I would expect to see.

[seco services]

no they don't have a ball they have their own float.
fit any cistern.
more chance of fitting them than the ball type as the ball needs more room for ball/arm.

[Mike-H]

so that one part replaces the valve, arm and ball? It should fit into the existing space and magically shuts knows to stop filling the cistern.

Crickey, whatever next, lights that work at the flick of a switch?

You cheeky scamp. They look like affiliate links. I may not know diy but I know websites

Thanks for the info. I used your links, but I will probably drop by the store on route home and pick one up.

Cheers,
Mike.
