Is there a check valve on a submersible well pump?
Check valves are designed to permit water to flow in one direction and are a requirement on all submersible pump installations. Their job is to prevent water in the column above the pump and in the pressure tank from draining back into the well when the pump shuts off.
How many check valves are in a submersible pump?
The placement and number of check valves required for a system is based on the depth of the pump setting in the well. Installation of 200 feet or less require one check valve on the pump discharge and one on the surface of the well. Settings 200 feet or deeper may require multiple check valves.
Does my well have a check valve?
Many well pumps have built-in check valves. Even if a pump does have a built-in check valve, we recommend that a check valve be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply.
Where is well pump check valve located?
Check Valve Located at the top of the pump to prevent back flow into pump and hold the head of water in the system.
Is there a foot valve on a submersible pump?
Nearly all well pumping systems, one line jet pump, two line jet pump, or submersible well pump, require a foot valve installed at the bottom of the well piping.
How do you know if check valve is bad in well?
It draws more power, causing a sudden, inexplicable surge in your electricity bills. If your pump is working fine, there is a possibility that your check valve has gone bad, allowing water from the pressure tank to flow back into your well. When the pressure switch senses pressure drop, it turns on the pump again.
Do well pumps have built in check valves?
How do I know if my well pump valve is bad?
Where is the foot valve on a submersible well pump?
In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump.
Do I need a check valve if I have a foot valve?
We recommend using only one check valve or foot valve in a pump system. A foot valve should be at the inlet to the suction line of turbine, centrifugal, and jet pumps. A check valve should be placed as close as possible to the discharge of a submersible pump.
