WATER HEATER STORAGE
Water Heater if the motorhome is to be stored during the winter months, the water heater should be
drained to prevent damage caused by freezing water contained in the water heater.
To drain the water heater, first turn “off” all electrical power, turn “off” the LP gas going to the water
heater, then turn “off” the water pump. Open both the hot- and the cold-water faucets to drain the water
lines and open the drain on the water heater to drain the entire system.
When re-activating the water heater after the motorhome is taken out of storage, make sure that the
entire water system, including the water heater, has been filled with water and the lines have been
purged of any entrapped air before relighting the water heater. Failure to do so may allow the water
heating element to be turned “on” before it is immersed in water; thereby, causing the premature failure
of the heating element and voiding the warranty.
PRESSURE RELIEF VALVE
The relief valve for over-pressure and over-temperature conditions is located on the exterior of the water
heater. This valve will operate if the water temperature reaches or exceeds 210°F or if the water pressure
reaches or exceeds 150 psig.
Since the water system in the motorhome is a closed system when all water valves are shut, the water
heating cycle can raise the temperature and, consequently, the pressure, of the water in the water heater;
thereby realizing pressure increases approaching 150 psig.
Should this pressure (i.e., 150 psig) be reached, the pressure-relief valve will begin “weeping,” that is,
minor dripping or leakage from that valve until the pressure drops below 150 psig, at which time the
pressure-relief valve will re-seat itself and restrict the water flow. This is normal operation and should
not be a cause for alarm. Do not obstruct or block the pressure-relief valve in any way, as this would
keep the valve from functioning normally and protecting the hot water system.
NOTE: WHEN WINTERIZING YOUR COACH, REMOVE THE WATER FILTER.
