Screeching toilet - what could I try?

[RufusA]

This is my Atlas toilet

and this is the inside

I have had a problem with my toilet for months. It screeches away. This never happens when flushing the toilet but sometimes a few minutes after it has refilled with water. However, sometimes it will just start screeching in the middle of the night, seemingly without provocation. It can continue screeching for about 40 minutes before stopping. Turning a tap on in say the kitchen can cause it to start screeching.

There is always a temporary cure. If I lift the tank lid and press the float down just a touch to release some water, the screech stops instantly.

I know very little about plumbing. I was wondering if anybody could give me any advice on how to try some things to stop the screeching noise.

Thanks.

Renew the fill valve or service it.

OK, can I replace it with any fill valve? I know the original was a A201 fill valve, but a quick Google and I don't think you can buy it anymore.

Also, is it difficult to replace, do you need a plumber? or is just a case of turning off the water, unscrewing and replacing.

Thanks.

Turn off water supply to toilet, lift arm on float valve and rotate 90 degrees. The top will come off, remove washer, replace washer and refit top section. Turn water back on and test.

thanks Andy, I'll give that a go. Got to go and get my new washer tomorrow first though!

I replaced the float valve with a new one from B&Q (only £12) and that has totally corrected the problem. No more screeching!

Thanks a lot guys for your help.
