Hi,
My mother in law's house has constant noisy plumbing and from what I read it is
caused by water hammer. It comes from the rising main, and not only when the
storage tanks are filling - but constantly!
There are two tanks connected to the rising main, a large one for household
water and a smaller one for the central heating both with ball cocks. I thought
I could replace both as they are of a much older type. When I went to turn off
the mains water I found that there is no stop cock inside the house and that
someone(?) had tar-macced over the one on the pavement outside.
Is there any way to install a stop cock on a rising main in-situ - like those
clamp type connectors. Does the cryo gas that freezes a plug of water in a pipe
work on the rising main. If it did I could easily cut it and insert a stop cock
in a few minutes.
The poor woman cannot sleep at night and I would become her favourite son-in-law
if we can solve this. Any help would be greatly appreciated!
