Do i really want to try this?
Fairly new to this 98 Dolphin, and only used the black tank rinse once and it worked fine.
I Decided to plug in the rinse hose to the fitting on the side of the black tank and rinse again since it's been awhile. Turned on the water and it started spraying out of the fitting instead of going into the tank. Turned it off and tried tightening but still no go. When I loosened the fitting, there was a bit of spray back of clean (hopefully) water; nothing appeared to be going in.
I know that there is a check valve to keep from contaminating the fresh water supply so I figure the check valve is stuck and not letting the fresh water in. I'm hesitant to try poking around on the check valve and possibly getting a shot of unmentionable stuff in the face.
I'm open to suggestions-
