Water Well Check Valve Leaking

This typically happens with swing type check valves in which flow reversal downstream causes the valve to close abruptly resulting in a pressure wave that propagates throughout the pipe.

Water well check valve leaking.

Evidently drainback with vacuum break is done. Next remove the handle from the stem and then loosen and remove the packing nut. The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. A leaky foot valve or check valve allows water to drain slowly down the well piping and flow back into the well.

Replacement is your only option. First shut off the water to the leaking water valve. At some point this will reduce the pressure in the pressure switch causing the pump to cycle back on to increase the pressure. If you have a leaking pressure relief valve on you well you should find this vi.

Remove the old washer and slide on the new one. A wet area developing anywhere along the route of the well piping often is a telltale for a leaky well pipe. Water hammer water hammer is a pressure surge or high pressure shock wave that occurs when a fluid in motion is forced to stop or change direction suddenly. Check the pressure tank s air valve.

How to replace or install leaking or broken well water pressure relief valve. In one case iron bacteria to clog the pipe leading to the pressure switch which causes the pressure switch to incorrectly sense the pressure.
