How to Winterize a Travel Trailer Water System

To begin, you will have to drain your water tank by opening the drain valve. Next to the water tank drain valve you will find your antifreeze fill valve. Simply put the clear hose into your jug of non-toxic RV antifreeze, turn the bypass valve so that it points to the antifreeze draw tube, and turn on the water pump to prime the system. You should see the antifreeze being drawn in immediately. Once the system is primed, you can turn on both the shower and sink to run antifreeze through the lines.

Run the faucet in your sink on both the hot and cold settings to ensure all lines get coated in antifreeze. Once antifreeze has run through the entire system, you can remove the drain plug from the hot water on-demand system, shut your water tank drain valve and turn the bypass valve to the off position. 

When the last freeze date has passed in your area, simply insert the drain plug in the hot water on-demand system and rinse your water lines out. A good method is to begin to fill the water tank with the drain open allowing the tank to flush while you run the shower and the tap on both hot and cold. Once the antifreeze is gone and the water runs clear, flush the system for a few more minutes. Let the tank drain fully.
