I'm not getting raw water supply to my Jabsco head. I'm guessing the intake is plugged. I dove the boat and stuck a coat hanger into the through hull, no luck.
Maybe blow it out (technically...in) with compressed air or water?
Could anything else be causing this? I didn't think so, as it seems to be naturally pressure fed. Normally, open the valves and the bowl starts filling. Close the valve and it stops. Fail to close the valves and sink the boat!
(And I'm ready for the jokes!
