How Do I Stop a Well From Banging?
Banging in wells is caused by the movement of water between your well pump and the pipes that connect it to the faucets in your home. Well pumps regulate water pressure by turning on and off to increase or decrease the pressure respectively. This process is known as "cycling" and, over time, can cause strain on the motor and wear on the components. The banging you hear is the sound of a high volume of water moving quickly through the pipes as the pump shuts down and can be controlled by minimizing the cycling of the pump. Does this Spark an idea?

1
Adjust the water pressure on your well's pressure meter. Normal water pressure is between 10 PSI and 60 PSI. Be careful not to set the pressure too high or your pump may remain on constantly.

2
Recharge your pressure tank. Drain all the water and reopen the gate valve to allow water back in. This will prevent your tank from being waterlogged, which can be a cause of banging. Pressure tanks rely on air pushing water out of the tank when the pump is turned off and a lack of air can cause the pump to cycle more than usual.

Install a cycle stop valve in your pressure tank. These valves help vary the pump's cycling rate to match your water usage and should stop the banging. For home use, a 1-inch valve is suitable.
