LOUD humming from water tank

[weggy1985]

Hi, I'm making this post not for me but my neighbours! They appear to have an issue which causes their plumbing or to be more specifically (I think) their water tank in the loft to making a extremely loud humming noise.

Now the noise only appears to start when they use the water and therefore I believe it is coming from their main pipe which fills their water tank in the loft.

Does anyone know what exactly could be wrong and how they can fix it. I'd really like to get a good night sleep for once (yes it really is that loud!).

Any help would be massively appreciated.

It will almost certainly be the ball valve assy. Simply replace it. Cheap job.

Where would this ball value be? Is it on the main tank itself? I'd like to go to them with some advice if I can so they can fix it. The more detail you can give the better. Again I'm very grateful

As advised this is likely to be the float valve filling the main cistern in the loft.

Either strip and refit or replace with

Okay, any idea how much it would cost to fit this?

Also just to give more detail, the sound it makes sounds a bit like someone blowing over the top of a beer bottle but 100 times louder. Just to check we're on the same terms.

Thank you

Dead simple replacement, so long as access is good enough.
As the others have said, it will be the ball valve - these can make noises anywhere between a hooter and a machine gun.

The last (and most accurate description for the particular situation) was "it's like the QE2 coming into harbour"
