What is a check valve used for?
A check valve ensures water, oil, or gas flows through a pipe in a unidirectional manner, preventing backflow and contamination.
What is the difference between a check valve and a backflow preventer?
While a check valve and backflow preventer serve similar functions, a check valve uses a hinge system to keep fluid or gas flowing in only one direction, and closes if it tries to move the other way. A backflow preventer uses increased pressure to control the direction of the flow.
