I suspect your coach still has the factory original hot water heater that did not have a manual drain. Rather, the coach uses a pneumatic valve to switch the hot water tank inlet/outlet opening from supply to drain. I your case, I would guess the valve is stuck in the drain position. These valves become inoperable over time and need to be discarded when a new hot water heater is installed. If you water heater is original it needs to be replaced before you have a leak that soaks the bedroom area. In general, the valve in question is connected directly to the hot water heater and has a pneumatic connection towards one end, a copper supply line in the middle and a smaller copper drain line towards the opposite end. Take the valve end plate ( spring loaded)off the end opposite the pneumatic supply and tap the piston back toward the center of the valve. The repair can either be quite easy or quite messy depending on the state of repair of the water heater and the pneumatic valve. The valve may also be located in a tight area where access to, and replacement of the end plate is difficult. Do not pressurize the air system prior to making the valve repair.
