The Check Valve is a fitting that has a flapper that acts as a one way trap door by allowing the water flowing out to open the flapper while the pump is running. When the pump stops the water in the discharge line forces the flapper or trap door closed.

There is a secondary benefit to having a Check Valve, it helps prevent the constant recycling and re-pumping of the same water left in the discharge pipe when the pump shuts off.
