Remove the clamp from the check valve.
Disconnect the AIR hose from the check valve.




Before replacing a check valve, test the valve for proper operation.
Install a vacuum pump to the nipple side of the check valve, AIR pump side.

Pump the vacuum pump to 10 inches Hg and observe the gauge.

Replace the check valve if the vacuum bleeds down to zero within 5 seconds.

if defective, to replace, unscrew from airpipe and install new 1. re attach hose and clamp. done
