What is a foot valve for a water pump?
What is a foot valve for a water pump?
A foot valve is a type of check valve that is typically installed at a pump or at the bottom of a pipe line (hence the name). Foot valves can be found in ponds, pools and almost anywhere there is a pump. These special valves allow the pump to stay primed, letting liquid to flow in, but keeping it from flowing back out.
Can a pump work without foot valve?
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. If there wasn’t a foot valve in place, the water would flow downward through the pipe, back to its original source. The pipe would be left empty of water, instead filled with air.
What happens when a foot valve goes bad?
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.
What’s the difference between a check valve and a foot valve?
Check valves and foot valves are designed to stop water from going backwards when the pump shuts off. Check valves are normally on the discharge side of pumps, and foot valves are on the intake of pumps.
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.
Where is the foot valve on a pump?
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 price of foot valve?

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?)
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.
What is foot valve used for?
Foot valves are used to prevent the backward flow of water through the pipe when the water pump is turned off, thus the column of the water in the pipe is maintained and all the issues are resolved.
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.
When to use a foot valve?
A foot valve is a component used with a pump to help the pump stay primed, ensuring that when people turn it on, it will immediately begin pumping water. Foot valves are found in wells, attached to pool cleaners, and in other settings where fluids are being pumped.
What are the functions of a foot valve?
What are the applications of the foot valve Extraction of water from underground water wells Industrial Rural fire protection HVAC Irrigation Car wash system
What is the function of foot valve in a well?
A foot-valve is located at the bottom of a well and acts like a one-way check-valve allowing water to go up the pipe toward the house but not drain backward into the well. A foot-valve is only used in a jet-pump situation (where the pump resides above ground and shoots some water down the well to help lift more water back up).
What is a foot valve on well?
Foot valves are a type of check valve and are placed at the pump’s wet well. Unlike other valves, a foot valve is created with a larger flow area than the actual pipe size to make sure that there is less head loss.
