Do shallow wells have foot valves?
Watch out: without a working foot valve, a shallow well jet pump is likely to lose prime and will stop working properly, risking loss of water supply to the building and even damage to the pump itself. The check valve is a one-way valve that lets water flow up from the well and into the well piping.
Is there a check valve in a shallow well pump?
Because shallow-well jet pumps use water to draw water, they generally need to be primed–filled with water–before they’ll work. To keep water in the pump and plumbing system from flowing back down into the well, a 1-way check valve is installed in the feed line to the 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. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.
How to diagnose a bad foot valve in a submersible well?
Check for leaks between the well and the house. If the pressure doesn’t hold, the leak is in the well. Winch the well the rest of the way out. If you determined the leak is in the well you have a leak in either the well pipe or a bad check valve.
What happens if the check valve on a well fails?
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. If the valve fails, water streams back down the well, and the pressure switch turns the pump on again.
Where is the foot valve on a well pump?
This article series describes the foot valve used on well piping for water well Pumps & Water Wells: we explain what a foot valve is, how they work, why they are used, and how to diagnose troubles with this special in-well check valve found at the bottom of well piping in some wells.
What causes a foot valve to stop working on a well?
When the system doesn’t hold pressure on the well side I think there are no leaks in piping, check valves, foot valve, pump body. So when a pump still won’t develop pressure I think that there is an impeller, seal, or voltage problem.
