Pipe noise near stopcock

[Chuck]

Chuck – So you mean there is an issue on the supply side between the house and the main in the street?

I was just pointing out that water coming in from the main will be at ground temperature, perhaps 10-15°C cooler than it is inside your house. If this is the mechanism there would probably be a slight delay before the clicking started and it would gradually slow down after a minute or two of running water.

Another possibility is your water meter is knackered. Here's a recording of a fairly noisy one:


If this is the issue the clicking rate will vary with flow in a fairly repeatable and persistent manner.

Noise can propagate quite quite well along a pipe full of water.

There are doubtless other possibilities but those would be high on my list of possibilities to consider.

Zzzjim – yes there are compression joins in the pipework past the stopcock, what is “Best’s technique”]........

I think zzzjim was just saying my idea of connecting above stopcock with temporary pipe to outside would confirm if noise is at or before (outside) the stopcock.

Ah right feel a bit stupid asking that now!!!

Anyway just went outside and lifted the cover for the water meter with the tap running and I can hear the exact noise I'm hearing in the house in there so I think it could be the meter. Rang the water company and they are going to come out and have a look!

(Thanks Chuck )
Just wait n see time !

(No such thing as a "Silly" question)

Yes fingers crossed they sort it!

Thanks all for your help and advice, I'll let you know how I get on.
