How do you test a well pump check valve?
This is easy to check. Turn off power to the well pump and run water after the pressure tank or in the house until there is no water pressure left. Using a tire pressure gauge check the Schrader valve on top of the pressure tank. It should be 2 PSI less than the cut-in or lower pressure.
Does a foot valve have to be vertical?
It is very important to install a Foot Valve in a vertical position to help insure a trouble free operation. If the installation instructions are not followed warranty or any warranty claims may be void.
Does a shallow well need a foot valve?
Foot valves are used in shallow well jet pump and deep well jet pump installations. The foot valve is required to be installed at the bottom of the well suction line piping. If you notice that a shallow well no longer has any water, one of the first things to check would be if the foot valve needs to be replaced.
What does a foot valve do on a well pump?
A Well Piping Foot Valve is a one way or anti-siphon valve which is installed on the pick-up end of the water pipe near the bottom of the well. The foot valve prevents water from flowing backwards out of the jet pump and well piping back into the well when the jet pump stops operating.
What is the main function of the foot valve?
A foot valve is found at the end of a pipe line in a suction lift application. They function as a check valve, but they also have a strainer affixed to their open end. The check valve is spring assisted. When the pump turns on, the pressure inside the pump column changes and the valve responds by opening.
How does a well foot valve work?
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.
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.
