Hoses and Pipes

If a leak is suspected on the pressure side of the system, or if a hose or pipe has been disconnected on the pressure side, the connections should be checked for leaks with a soapy water solution. With the AIR pump running, bubbles form if a leak exists.

CAUTION: Refer to AIR Check Valve Caution in Service Precautions.
