Can I call it a repair, if I didn't use any tools, duct tape, or glue?
For several months now, I've noticed a water hammering in the pipes when I shut various faucets throughout the house. I know that's bad, it puts stress on all the pipes.
At each faucet, the typical set up is to have about a 6" extension of pipe rise above the take-off point. This traps air, and provides a cushion against the sudden closing of a faucet against the non-compressible water. Over time, that air gets dissolved into the water.
So I finally thought of it when DW was around to open & close faucets on command (well, OK, I asked nicely
). We use our cordless phones as walkie-talkies (need to be within range of the base station). I close the valve to the well pump - pressure tank side, have her open faucets set at middle (half hot, half cold), and I open the faucet in the basement to drain and let air into the system. Took just a few minutes to run through all the faucets, then turn pressure back on and close them as they pushed air out of the lines (but the air in the anti-hammer sections is trapped).
It worked. No more water hammers! Only one of the faucets coughed up some sediment and crud, I may have to clear some of the filters in the aerators over the next few days, but I'm glad I got this done.
