OK I realise this is probably very basic....

When I flush the loo, the cistern makes a noise for a few seconds just
as the cistern finishes filling. The noise is like a mini foghorn. If I
turn on another cold tap in the house the noise goes away while the tap
is on.

I am guessing that the ballcock / valve my need replacing but is there
another wayI can fix this?

TIA

If you have a service valve

on the inlet pipe you could try turning that down a bit to reduce the
pressure,

Water hammer. Pipes probably need to be better clipped down.

Or not... Had fog horn type hammer from the coldwater storeage tank
here after I carefully clipped the pipe work to rafters etc. Slacking
of the clips so the pipe could move cured it.

I don't think there is a single known way to cure this sort of
problem, turn up/down the service valve a bit if there is one, change
the washer in the valve, clip the pipework more securely, unclip the
pipework, some combination of one or all of them...

You need to apply what little knowledge you have to something else.
Try paint by numbers.

Hi John

Have you recently turned off the main water supply to the house?
If so you may have "opened" the valve/stop-cock further than it was, and
introduced the problem.

If not then, as others have suggested, look at replacing either the washer
on the ball valve, or the whole water fill arrangement.
As TMH suggests, this will be a lot less disruptive if you have a service
valve on the feed (and 2 toilets preferably).

The washers can go quite hard and "vibrate" as the ball valve nears closure.

Thanks for all of the suggestions. It looks like I have a number of
things to try (keeps me off the streets....).

I really appriciate the help ... first thing to try, I think, is
replacing the washer, it looks to be the most simple solution.

Cheers
