I just bought a house that has a kitchen faucet that bangs when the faucet is opened- not when closed. It doesn’t happen on any other fixtures. Also, when you try to use the sprayer, the water shuts off and the sprayer just dribbles. When you release the sprayer lever the water doesn’t come back on for a second, then bangs and comes back on. This is driving me nuts! any help would be appreciated.
