Definition - What does Foot Valve mean?

Foot Valve is a type of a check valve that is created to maintain a large flow area so as to reduce the head loss. This valve is either made up of PVC plastic or stainless steel. It is installed at the lower section of pump suction line but inside the wet well. It should be made of high quality material as it maintains the pump between the pumping cycles thus improves the pumping efficiency.
