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.
What happens when a check valve goes bad?
A check valve is designed and installed into a line or pipe in such a way to allow the fluid to flow only one direction. When a check valve fails it allows the fluid o flow in either direction. This action may cause a pump to fail or the fluid to flow back through the pump when it is stopped stopped.

Do submersible pumps have a check valve?
Check valves permit water flow only in one direction and are required on all submersible pump installations. Some submersible pumps have built-in check valves, and are suitable for operation without an external check valve, provided the pump setting is not too deep. Where should a check valve be installed?
What is a check valve?
Check valves used on well water system piping are used to hold pressure in the system when the pump stops. Check valves on well piping also prevent backspin of the well pump, water hammer and upthrust inside the pump. These problems can damage the well pump. [1]
Where should a check valve be installed on a submersible pump?
On a submersible well pump installation, if your well water pump does not have a built-in check valve [many submersible pumps do have a check valve], a line check valve should be installed in the discharge pipe within 25 feet of the pump and below the drawdown level of the water inside the well.
Can you use a check valve on a jet pump?
Many plumbing experts advise that unless the check valve is part of a water tank makeup air system, it's best to use just one check valve is needed and just one should be installed in most cases. . If the check valve on a jet pump has failed, it makes sense to replace the valve, or if needed, the pump assembly.
What is a spring loaded check valve?
Spring loaded check valves close quickly, prevent water hammer, and protect the pump or impeller assembly from back-flowing; most importantly a properly functioning check valve prevents loss of prime in the well piping system.
Do you need a second check valve for a submersible well pump?
Watch out: Other well installers and plumbers do not agree with the Water Systems Council advice cited above. These experts recommend that you do not install a second check valve on submersible well pump systems; rely on the valve that is on the submersible pump.
What is a check valve on a sump pump?
Check valves on sump pumps: Check valves are used in other plumbing applications as well, such as on sump pump drain lines to prevent back-flow of water from the sump pump exit piping into the sump pit when the sump pump turns off. See SUMP PUMPS GUIDE.
Is a foot valve a check valve?
The foot valve is itself a check valve. For deep wells (hundreds of feet) the well pump manufacturer will usually recommend additional check valves at intervals in the riser pipe. But there are special requirements for check valves on water supply systems and pump systems used fire fighting applications.
Why do I need an external check valve on my pump?
External check valves are usually installed on impeller type pumps to prevent loss of water or unnecessary head pressure at the impeller.

How to tell if a check valve is leaking?
Place a hand on the valve and put your ear next to the valve if the temperature of the fluid will allow you to do so safely. Any sound of fluid running indicates a leak.

This is a type of check valve because it only allows flow in one direction. Similarly, where does the check valve go on a pool pump?
Why does my water pump cycle back on?
At some point, this will reduce the pressure in the pressure switch, causing the pump to cycle back on to increase the pressure. This is called intermittent pump cycling. 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 ...
What is a leaky well pump?
Water is essential to life, but a malfunctioning pump can be a real hassle. A leaky foot-valve or check valve allows water to drain slowly down the well piping and flow back into the well. At some point, this will reduce the pressure in the pressure switch, causing the pump to cycle back on to increase the pressure.
How to stop a pump from leaking?
A leak anywhere in the system can cause your pump to cycle intermittently. The key is to narrow down the location as much as possible. Start by closing the main valve to the house. The main valve is the one just beyond the pressure switch.
Where is the foot valve located?
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).
