The pump was replaced by the PO just before we bought the boat
. Seems to pump OK but when you lift
the lid there is always nasty brown water
in the bowl, even when pumping overboard
. Tried leaving the lid up and using fresh water
to flush with, same result. Thinking the vented loop vent is plugged and water siphoning back into the bowl. Should not be possible with the two check valves in the pump. I can get the joker valve out by unscrewing the cover, thought that would be easier than disassembling the whole pump. Diaphragm must be OK since the pump pumps and there is no leak. Hate to spend $50 for a whole kit if I only want to replace the joker valve.
Had two Lavac
heads on the boat
, neither one worked worth a damn. Replaced the aft one with a Raritan
Elegance. Pumping potties seem kind of crude, rude and socially unacceptable. Just my opinion.
