A damaged check valve can allow reverse flow, leading to system pressure loss and erratic operation. Crown, the OE maker, lists this aftermarket replacement part under number CR121819. The check valve permits fluid to move in one direction only, using a spring-loaded disc or ball to block backflow. When the valve fails to seal, the system may lose prime or experience uncontrolled reverse movement. During a pressure test, a leaking check valve often produces audible chatter or visible pressure gauge fluctuation. Verify the serial number or application, then call (562) 693-7748.

Part number variants: CR121819, cr121819
