I am having my boat worked on at a local boat yard. Bottom paint, fixing the bangs and dings. I of course didn't have anything to do with, they just appeared one day. I would like to drain the water from the tanks and bildge while the boat is in the yard. I can't find a release valve for the fresh water tank or the holding tank. and the bildge pump has done all it can and i still have water.Any sugestions???
