mains water
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 cock. 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. |
