What does a foot valve do in a well?
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 happens when a foot valve fails?
A leaky foot-valve or check valve allows water to drain slowly down the well piping and flow back into the well. It can drastically increase your electric bill and occurs when no water is being drawn from the system. Unfortunately, a leaky foot-valve or check-valve is not the only cause of intermittent cycling.
Can a foot valve get clogged?
A clogged foot valve could be reducing the rate at which the pump can pick up water from the lake. A worn, damaged, or debris-blocked impeller in the pump itself could be the trouble as could an air leak at the pump (do you see bubbles in the output water?)
Why is a foot valve needed?
Why Are Foot Valves Needed? Foot valves are beneficial because they prevent damage to water pumps that can occur due to dry runs, as well as stopping wastage of energy. These valves are a necessary part of all water pumping systems.
Which is better foot valve or check 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. The check valve slamming shut from a full open position when the pump is cycling repeatedly is the main cause of check valve failure.
How long do well foot valves last?
The plastic pipe, usually lasts quite a while. Unless you have an extreme amount on minerals , like calcium, the PVC pipe should last longer than you. It’s the galvanized connect pipes the corrode rather quickly. The foot valve will need replace ment bout every 15 years , give or take a few years.
Do you need a check valve with 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.
