Basics of Check Valve

A check valve is a fluid control valve that admits only one direction of fluid flow. The ball, needle, and diaphragm are the three most essential check valves. Ball check valves are the most frequent check valve used in domestic plumbing. 

The term derives from the valve’s function to prevent backflow. Check valves can also be utilized in various applications that need one-way flow.  The best check valves for sump pump systems are critical components.

How Do Check Valves Work?

All best sump pump check valves should be installed correctly and with the correct check valve type for the specific sump pump system. Improper installation or the wrong check valve can lead to significant problems down the road. Check valves are essentially valve bodies with two flaps operated by a spring.

• When the valve is mainly used to prevent backflow, one flap locates inside the pipe and the other outside the line attached to the building or sump pit wall.
• When the fluid is flowing away from the building, the force of the fluid against the external flap will push the flap upwards. This will cause the internal flap to open and let the fluid from the discharge line into the sump pit.  
• When the fluid stops flowing away from the building, the external flap will fall back down and close off the flow from the discharge line into the sump pit.

This cycle will continue whenever the sump pump is in operation. There are many best sump pump check valves, each with advantages and disadvantages.
