Need help with water systems
Lynn,
My 1999 has three drain valves. One on the main tank (ball valve lever) and two nylon valves on the ends of lines draining the hot water tank. Those are located under the right rear seat. Your model may be different, but you should be able to see or feel these by following the pex tubing from the water tank. My guess is someone left those open after winterizing the unit.
