Pipes rattling - water hammer?

martinthebandit

It might just be that the top of your vent stack is blocked but, if it was me, I would be draining a sink full of water out while holding each of those plastic pipes you can see in turn.

If it makes a difference to the noise then that is the one I would be seperating from the others or securing better.

That open ended bit of pipe looks a likely culprit to me, where does it come from?

Oi,

Stop picking on an innocent piece of WC overflow pipe

Isn't being redundant enough for you?

Why does it's nationality matter?

Noise in pipework can be a nightmare to track down.

We also have had knocking etc I turned down the tap as you suggested and so far haven't heard any.
Thank you

But you've not solved the underlying problem. All you've done is get rid of the noise.

So would the solution to a nasty engine knock at 40 be to drive at 30 when you don't hear it?

How on earth can you compare?

It wasn't supposed to be a like for like comparison (I suppose I could have left less to the imagination though) but its the same principle. You don't remove the underlying problem with water hammer by throttling back the main stopcock - all you do is treat the symptom not the cause. What happens when someone opens it up again?

Perhaps you could enlighten us as to the cause?
