If you have a sump pump check valve installed and it fails, your sump pump will not work properly. The check valve is designed to keep water from flowing back into the sump pit after turning off the pump.
If the check valve fails, water can flow back into the pit, which can cause the pump to turn on again and run continuously. This can be very frustrating and costly.

How to Tell if the Check Valve is Flawed
If you notice your sump pump is running more than usual, or if it seems to be running all the time, there is a good chance the check valve is bad.
You can also tell if the check valve is bad if you hear water flowing back into the pit after the pump has turned off. This is called a “water hammer,” it is a sign that the check valve is not working properly.
The Sump Pump Moved from its Original Position
If you notice your sump pump has shifted position, this is not normal. It could be a sign that the check valve is bad and needs to be replaced. If your sump pump has moved, it may indicate that the check valve is misaligned.
There are several reasons why a pump may move. One cause is ground movement, such as that caused by earthquakes or unstable soil in the basement of a home.
Defective Valves or Faulty Sump Pump
It is essential to have a quality product for everything you often use. This is especially important for sump pumps since they are responsible for keeping your basement dry.
If you have a defective valve or sump pump, it could cause extensive damage to your home. A professional should check and repair any defects as soon as possible to avoid further problems.
Debris Blocking Discharge
If you see or suspect that debris is blocking your check valve, it is important to have it removed as soon as possible. Blocked valves are one of the most common causes of sump pump check valve failure.
The debris can be anything from leaves and twigs to mud and concrete. If the valve becomes blocked, water will back up and eventually overflow into your home.
Current check valve technology can remove debris, but it may be done manually if the obstruction is severe. Check that water flows out of the discharge pipe after removing the blockage.
Reasons for sump pump check valve failure
There are several reasons why a sump pump check valve may fail.
Damaged rubber seal
One reason for check valve failure is that the flap or rubber seal may be damaged or worn out. If the flap is damaged, it may not seal properly and allow water to flow back into the pit. The rubber seal can also become brittle and break, allowing water to leak past it.
Sediment or debris
The most common reason is that they become clogged with sediment or debris. Over time, this can cause the check valve to stick in the open position, which will allow water to flow back into the pit.
Improper installation
Another reason for check valve failure is improper installation. If the check valve is not installed correctly, it may not seal properly and allow water to leak past it.
Broken spring
Another reason for check valve failure is that the spring may be damaged or broken. The spring helps to keep the flap closed when the pump is not running. If the spring is damaged, the flap may not close properly and allow water to flow back into the pit.
Cracked housing
The third reason for check valve failure is that the housing may be cracked or broken. This can happen if the sump pump is installed improperly or not maintained properly. If the housing is cracked or broken, water can leak out and cause the pump to turn on again.
