Noise when flushing toilet

[ultimatelightweight]

Hi Forum,

Newbie here so please don't laugh!

When flushing my toilet, for the duration of the time it takes to fill the cistern back up there is a loud noise. Can't really describe it! There are also vibrations felt when holding the inlet pipe. The noise has been happening for a few weeks now.

I've read some of the other posts on here and some say it's the float valve in the cistern. Is that possible? The noise isn't coming from the cistern, more like the pipes.

Could it be trapped air? I'm hoping it's not water hammer as all the pipes are under the floorboards!

I've tried consistently running the water feed into the tank, but that didn't clear the issue.

Any advise would be really great as the credit crunch is going to make a plumber callout ruin Christmas!

Thanks,
Ian

I'd start with replacing the ball valve assy or at least fitting a service kit to it.As these assemblies are cheap to buy just replace it if you have the DIY skills.

Had a similar thing which turned out to be the service valve on the inlet pipe. I opened it fully and the noise ceased.

Do you have one of these?

Just a thought.

Yeah I'll try that. Thanks for the suggestion.

Yes I do! Should I try adjusting?
