Admin What does a foot valve connect to?
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 a foot valve and how does it work?
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 is the foot valve and why it is required?
The foot valve is a lift check valve which is usually installed together with suction strainers in the suction line. It prevents the suction line from running empty after the pump is stopped (also see Valve).
Where do you put a foot valve?
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. This protects against loss of prime in the well piping system.
What is the function of sluice valve?
A large valve in which a rectangular or circular gate slides across the opening. It has been used in oil tankers to permit gravity flow from tank to tank, with the valve being operated from the weather deck.
Can foot valve be installed horizontally?
The flapper type check & foot valves work using gravity. They use a disk and rubber or leather flapper attached at one side of the opening. These are generally installed vertically but can be installed horizontally as long as the flapper closes down.
How deep should a foot valve be?
To prevent sand and sediment from entering pumping system, foot valve/strainer should be at least 5 ft. (1.5 m) above bottom of well.
