fog horn noise from cold water pipes into toilet after flushing

[emma williams]

Hi When I flush my toilet the cold water pipe feeding into the toilet has a very loud noise sounding like a fog horn which you can hear in other rooms an I can feel the pipe vibrating. It I push on the pipe slightly it stops but as soon as I let go it starts again. Anyone know what this might be?

This is my first house, I have no plumbing knowledge at all and don't know if I need to call a plumber or if its something that might be easy to fix. Im hoping its an easy one as the roof has also started leaking so could be an expensive month!

thanks for your help!!!!!

Liable to be the fill valve in the cistern, could be a diy job, all depends on what the access is like to the valve.
Either way not expensive to fix

If it is a ball valve type fill valve (plastic valve with ball float on end of long arm across width of cistern) then it would make a fog horn noise if on high pressure mains water and diaphragm washer is worn.
New diaphragm washer should sort it, or have the valve replaced with a fill valve (preferably with brass tail) more suitable for quiet fill on high pressure

Yes it is a plastic valve with a ball on a long arm. cheers!

When this happens in flats or old peoples blocks they all get shy about flushing the bog in the night cause the neighbours all know what they have been up to...its an easy fix but most probably a simple plumbers job

And most of us are fairly simple 😉

Thanks for the kind replies. Out of interest how much roughly would I expect to pay to get it fixed? just as a guide when I ask local plumber cheers!

Depending where you are based, shouldn’t be more than a callout fee. £40 - £80?

Struggle to get a plumber to turn up to things like this in my experience. Always seems to be some little niggle when I’m away and no ones interested in an easy few ££.
