A friend of mine ahd the same problem.

He had a Rule 750 with 3/4" discharge hose.
about 6" from discharge had inline check valve by whale??
Every thing worked great BEFORE installing the new check valve then
the Rule would run great but no water would discharge.

He, on my advice, **** canned teh check valve and used a Groco bronze
vented loop. Problme solved.
Pupm works fine.
