We just redid some plumbing
, including the feed to the hot water
tank. As part of this, we took out the QEST check valve and installed a bronze swing check valve. Now, the hot water
tank is acting as an accumulator: It has enough pressure that the water will run up to 20 seconds (from one faucet) before the pump quicks on. Similarly, the pump the runs for up to 20 seconds after you turn the faucet off. The pressure at the faucet seems higher, as well, but then I never measured it.
I suppose this could be normal and we had something wrong before, but the delay is a bit disconcerting. We haven't turn the heating
element on because of it. Is it normal? Are we over pressuring our hot water tank somehow? (We tested the TPR valve, it seems to work) Am I just panicking because I have been overwhelmed with projects the last two weeks?
