Was taking another look at the pump out hose arrangement. Beings a how the exit is low and the hose will be exposed to effluent 100% of the time, how about using schedule 40 PVC pipe to connect to the tank? Then route the pipe under the tank (there is just enough room) and up above the tank top where it can connect to a piece of hose. Probably could route the pipe all the way up near the fitting and use a 6" hose for the connection.
Thoughts?
Also, what do you use for the vent hose. Mine's just hardware store hose and that has to permeating!
Appreciiate all opinions,
Joe
