Why is my water thumping?

You’re most likely to hear banging pipes when the water is turned off, and it can happen near water-using appliances, such as washing machines and toilets, when the automatic fill valve shuts off.
Why does my water pump make a humming noise?
at WATER PUMP PRESSURE SWITCH NOISES. Clicking may be a normal on-off switch sound, but humming from the pressure control switch may indicate a stuck relay and risk control burn-up; other humming sounds traced not to the pressure switch itself but to the water piping and water pump may also be normal.
Why does my kitchen faucet make a thumping noise when I turn it on?
