I spent the better part of the day under my RV covered in shit. I had no problem cutting the valve. Getting the gate out was easy too. Too bad nothing happened after that. There is also a blockage……sigh. Called a friend with a snake and he snaked it, which led to the discovery that there was not enough water in there. Combined with that, heavy burping, water jets and an entire bottle of Dawn, I got enough drained that I could add water and a digester bomb. The toilet works, but the tank is still not draining. Tomorrow I will try some more. I have a feeling this is gonna take a couple days and i just took the best shower ever. Bedtime
