Shower / Hot water making huming noise

Lord_kit

Hi All,

Hope you can give me some advise on whats going on.

I turn on my hot water tap in my bathroom and the pipe behind the shower is making loud humming nose. It's not a banging noise just very loud.

I then tuned off the stop tap., which is under my sink downstairs.

We have a combi boiler, if that makes any difference? reading other forums it looks like there is Air trapped in the pipe.

Any ideas on what i would need to do?

Cheers,
Ketan

The pipe may be loose and reverberating, or there may be air in it

does it happen when the rads are on too?

what are Rads?

I think there must be air in it?

How do i get rid of it?

Its almost certainly not air. With a combi boiler everything is on mains and you don't get airlocks at mains pressure.

Try reducing the flow rate of your cold water supply by closing the stop c o c k slightly. You only need to reduce it a little bit.

Try that and tell us what happens.

Cheers

Well it turns out i've got a leek.

Looks in my bathroom, when i opened the stop tap a little. I can see water leaking near the radiator.

Also this has now gone under the bath room tiles, and started dripping down stairs :-(

Time to call the insurance company / plummer.

Thanks all for the quick replies
