Well pump check valve installation.

This is called intermittent pump cycling. Many well pumps have built in check valves. Normally the first check valve should be installed on or directly above the pump. A leaky foot valve or check valve allows water to drain slowly down the well piping and flow back into the well.

On a submersible well pump installation if your well water pump does not have a built in check valve many submersible pumps do have a check valve a line check valve should be installed in the discharge pipe within 25 feet of the pump and below the drawdown level of the water inside the well. Install the valve with dye imprinted flow arrow in the correct direction. For those that don t pump installers usually install a check valve in the well immediately above the submersible pump.
