Hello all
This is a new installation a friend of mine has just had completed in her cafe.
She can't contact the plumber who did the job for some reason. Not picking up.
It's only a week old.
He has just fitted a sink in a part of the cafe and the pipes are hammering like hell
when you turn off the taps so much so that they are jumping out of the clips and
you know how tight those things are. They won't even reach the clips in some places.
It's as though he has cut them too short.
The joints are all compression and there are 10 x 90 degree elbows in each of hot and cold
water supply that I can see and maybe a few more that I can't see.
For now I have turned down the mains pressure as much as I can and it has gotten rid of the
hammering on the cold supply but the hot still has a ping. That's because the only
means I have of reducing the pressure on the hot supply is an iso.
The problem with this is that there are dishwashers and central heating needs
to consider so I would rather have full mains pressure and to that end I consider this
a temporary solution at least for a couple of days.
I attach a picture of what's going on under the sink. If this guy doesn't turn
up in the next few days I am thinking of removing everything under the sink between
the isos and the taps and replace it with flexi hoses.
Will that help dissipate any of the energy in the pipes? I mean through movement
off the flexi hoses?
Take a look at these pics. Is there any kind of small expansion vessel available that
might be suitable for this? To buffer the shock?
The wastepipe is leaking too, which is easy I know, but I am reluctant to get involved
given this is only a week old and I don't want to give this guy an excuse to wash
his hands of it by touching it.
Any advise appreciated.
Cheers
