Hello,
Our pipes keep making "kicking" noises when the (cold) taps are turned on. I saw that a PRV was cheaper to buy than a pressure gauge so I bought the Comap PRV from Screwfix. Has anyone used one of these? How do they work to reduce the pressure?
I fitted the supplied gauge but could not leave it in place permanently because it leaked. Do you have the same problem with yours or is mine faulty? I wonder why they don't supply a washer of some sort to stop this?
With the screw turned to allow maximum pressure, my supply appeared to be 4 (bars?). Turned down to the recommended 3 (bars?) the kicking noises have gone.
It came with some clever adaptors that allow 15mm pipe to fit inside
22mm connections, I presume by friction. Are these reliable?Whilst on my hands and knees under the stairs where the water enters the house, I found that there is a slight leak. The water enters the house in a black plastic pipe. This pipe looks 22mm. It goes into what looks like a 22mm to 15mm straight adaptor from which runs 15mm copper to the stop c*ck. The 22 to 15mm compression fitting and the pipes were wet. Possibly the copper pipe was wet from condensation onto the cold pipe but I would not expect the plastic pipe to have condensation; I'm thinking that it is more likely that there is a leak.
There's not much of the plastic pipe to play with. What's the best solution: change the 22mm olive? Should I use one of those Fernox leak sealing pastes?
Thanks, Stephen.
