Where is the foot valve located? 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.
What happens when a foot valve goes bad?
A common cause is a failed check valve. 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 does a foot valve go on a well pump?
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. Similar to the check valve, the foot valve prevents water from flowing back out of the jet pump.

How do you know if you have a leaky foot valve?
It should hold the pressure for longer than an hour without cycling. If the pressure holds, your pipe and check-valve are not the problem. Check for leaks between the well and the house. If the pressure doesn't hold, the leak is in the well.
How do you check a well check valve?
Shut off the water supply to the check valve. Follow the water line backwards (the flow of water is indicated by an arrow on the check valve) and switch off the next valve. Wait 15 to 20 minutes for the water pressure to subside. Check the valve for debris by tapping its side with the handle of a screwdriver.

How do you get a foot valve off the bottom?
One option is to build a simple A-frame out of wood and anchor it to the lake bottom. Another is to run the line through a concrete building block. Keep your foot valve at least 30 cm off the bottom, and at least one metre below the lake's surface, to account for water-level fluctuations.

Where is the check valve located 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.
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 much does it cost to replace a well valve?
The device itself ranges from $35 to $600, while professional labor costs between $100 and $400. Expect to pay between $70 and $250 for a backwater or check valve, including install.

What is the purpose of foot valve?
Foot valves are designed to keep the pump primed, allowing the liquid to flow in, but not out. There are screens that cover the valve opening that will become clogged after a period of time – especially when they are used to extract water from wells or in ponds.
How do I know if my well pump valve is bad?
Usually when a check valve fails the water will run backwards after the pump shuts off, and the pump will start again even when no one is using water. But if you have two or more check valves, the lower one can be masking the problem of a bad upper check.
Where do you put a check valve on a shallow well?
The check valve should be installed in the suction side piping as close to the source of water as possible. It should not be installed within 2' of the pump's inlet, or anywhere on the discharge side of the pump. A foot valve functions just like a check valve plus has a strainer on it.
How long do check valves last?
Now for the verdict: in most cases, a check valve will last approximately 10 years.

How much pressure can a foot valve hold?
A foot valve doesn't damage the piping to which it's attached. " In general Flomatic valves are pressure rated 400 psi or 920 feet of water pressure. This does not mean that a valve can be set at a well depth of 920 feet.
