Water in black tank after dumping????
Hi folks, I have a 30 gallon black tank, the other day I filled it to the top, then drained it into my 32 gallon 'Blue Boy'. It came up to near full, probably 2 inches from the top. I still have what appears to be an inch or so in the black tank looking down through the comode. I am fairly level.
Would it be normal to have a little still in the tank?
Thanks in advance!
