On our TM the water heater drain valve is located in front of the street side wheel - almost directly below the water heater. Just in from there is the 20 gallon fresh water tank drain. That drain may also be used to drain the cold water side of the street water connection lines. Toward the bumper, street side is another set of drains, one for hot water and the other for cold water street connection water lines..
