In the Trades
I have been in the well & pump business for many years, however I have run across two jobs recently with the same problem, noisy plumbing. The noise is in the trunk line, about 15' away from the tanks. The noise sounds like a Clarinet is being played when the water is turned off at a faucet or toilet. I have checked the tanks for proper pressure, one was a Well X Trol, the other a Well Rite. Annular pressure between bladder and shell was 38psi each. The pumps were drawing the correct running amps, dead head pressure against a valve & gauge was within specs given the size of pump, pump setting and static level. The pumps are hung on 1" 160 psi poly with 1"160 psi poly offsets. The trunk lines are 3/4 copper tubing with 1/2 branches going to the sinks & toilets. The noise seems to occur when the system is at the high end of the pressure differential, 60-65 psi. The noise occurs even if the pump is not running, so it isn't due to vibrations in the wet end of the pump unit. The noise can't really be felt or heard in the tanks, so I don't think it is a check valve problem. Both systems use ball valves rather than stop and waste valves. On the job today if you put your hand on the pipe where the noise is coming from it muffled it a bit, but you could still feel the sound coming through the floor.......The houses are about 20 years old.
Any ideas?
