We just purchased our first RV, a Sundance 3300CK, and it appears the Black Tank valve is leaking by. I noticed during the walkthrough with the dealer that the Black Tank valve did not go in as far as the Grey Tank valves, but he operated them and did not show any concern. Therefore, I thought that this was "normal." We have taken 2 trips and both times there was 3-5 gallons of waste waiting for me when I pulled the cap off! Any suggestions on how to fix this issue? The dealership is a considerable distance from our home, and I would like to fix it myself, if possible.
