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.
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?)Apr 30, 2018.

What does a foot valve do?

How long do check valves last?
While typical component lifespans are application specific, manufacturers suggest metal and plastic check valves should be replace every 5-7 years whereas check valves manufactured from rubber may remain fully serviceable for up to 35-50 years.
Does a check valve go before or after a pump?
The most common installation is at the pump. A check valve may be installed on the suction side of the pump to maintain the pump’s prime in the event of a pump shutdown. A check valve will be used commonly on the discharge of the pump to prevent backflow from the downstream system, when the pump shuts off.
What is the best foot valve?
PVC foot valves are a good choice for most applications; they are cost-effective and lightweight. However, in applications that require temperatures or pressure that don’t allow for PVC, or that require specific chemical resistant materials, there are metal valve options like brass and stainless steel.
What happens when a check valve goes bad on a well pump?
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.

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.
How far off the bottom of a well should the 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.
Do you need a foot valve on a shallow well?
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 is shallow well?
A shallow well is a hole which has been dug, bored, driven or drilled into the ground for the purpose of extracting water is a well. A well is considered to be shallow if it is less than 50 feet deep. The source of a well is an aquifer.
Do shallow well pumps have check valves?
Do I need to use a check valve or foot valve with this pump? Yes. The check valve should be installed in the suction side piping as close to the source of water as possible.
How far should check valve be from sump pump?
Best height ( unless owner’s manual states otherwise) is two to three feet off of the top of the sump pit. This way your sump pump motor doesn’t have to work as hard as when your check valve is in lower position.
