Can anyone please help with a noisy water pipes problem?
It's developed over the past few months and what happens is this....
Shortly after drawing hot or cold water from the downstairs or upstairs
taps, a loud "moaning" noise can be heard from the supply pipes to the cold
water tank in the loft. There is also some vibration on the pipes. The
racket goes on for about five minutes.
Turning on a tap (upstairs or downstairs) and letting it run for a few
seconds stops the noise temporarily, but it returns a minute or two later
and, again, takes about 5 minutes to subside.
I seem to recall reading stuff about "water hammer" and wonder if this is
what I've now got! If so, what's the cure? If not, has anyone got better
ideas on the source of the problem?
Thanks in advance....
