Climb under the RV where the water heater panel is. You'll see a white circular (about 4 inches) that unscrews. Open it and you'll find 3 valves. Switch the position on all 3 valves. (Assuming they were in the correct position to start with)

Mine is a 3 valve system. Assume yours is as well. Close the cold water in and hot water out valves. Open the 3rd one. That bypasses the HW heater. There is also a valve back near the pump that has to be open in order to pump antifreeze through the system.
