Pipe Rattle

[Henryvl]

I have been getting a tapping/knocking in the cold water pipes, when I turn on a tap or flush the toilet.

If I turn on a tap slowly there is not problem.

The pipes are well lagged/cushioned so I do not think they are banging against anything.

Last week the ‘Water boys’ dug up my main stop cock outside my house, looking for a leak.

They found one, and did the repair.

I suppose it is logical to assume that this increased the water pressure to the house?

So far I have turned off my stop cock in the house, turned on all the taps and flushed the toilet.

Then I turned the water back on, but the problem is still there.

It seems as if it is a pressure thing, but any advice to remedy this would be most appreciated.

I don’t have a pressure gauge, (until it arrives from Amazon) but I turned the cold tap in the kitchen full on, and it took approx 3 seconds to fill a 1/2 litre jug.



Thank you,



Henry.

A shock arrester may help you, in the meantime try closing the stop cock half a turn.

Do you mean the stop cock in the house?

No luck with that.

I have checked my water pressure with a gauge = 78psi
