My husband and I installed a new kitchen faucet a few days ago (we are not plumbers). Ever since then, when you shut off the hot water (or when the dishwasher runs), it makes a banging noise. From our internet research, it sounds like a water hammer. There seems to be all sorts of solutions on the net, but some even contradict each other. We did try draining the air out of the pipes, but even that had very different methods for how to do it, so not sure if we did it correctly.
Note, before we installed the new faucet, there was never a sound when you shut the hot water off.
Any thoughts on what to do? THank you
