When winterizing there is no need to add RV Antifreeze to the hot water heater. Just follow the steps listed below:
1. Make sure that the water heater is off and cool and that the RV's water pump is off and that the RV is not hooked up to city water.
2. Open up the Water Heater's drain plug and Pressure relief valve and completely drain all of the water out of the water heater.
3. Now put the water heater bypass valve into bypass position (depending on the model and make of RV you have the bypass valve is normally located on the back of the water heater)
Note From RVing Al: If your RV is not equipped with a water heater bypass valve you can buy an After Market Water Heater Bypass System.
Draining and bypassing the water heater is only one of the many steps you need to take to properly winterize your RV. You may want to take a look at video below to understand the whole process.
