In this fourth blog in our “Ask an RV Tech” series, we ask our resident expert, Hank Dudley, “Is there anything special I should do to my RV plumbing system in the winter?”. Hank says, “Absolutely! As you winterize your RV, you will need to drain all tanks and water lines by opening the low point drains. If you live where the temperature drops below freezing, you will want to use a special non-toxic RV anti-freeze.” Some people just blow out the water lines, but that may not get out all of the water. You’ll need to drain the fresh water, the septic, and the water heater, making sure that all the valves are closed afterward, so that you don’t lose the anti-freeze that you’re about to pour in. Begin by adding anti-freeze to the fresh water tank. Turn on your water pump and open all the faucets until you see the pink anti-freeze begin to flow and then turn the faucets off. This may take four or five gallons. Flush the toilet until you see the pink anti-freeze in the bowl. If your lines run dry at this point, you’ll need to add more anti-freeze. Turn your water pump off and pour a little anti-freeze down each trap, including sinks and shower, as well as an additional gallon or so down the toilet to winterize the tank. Remember… Even if you use your RV in the winter time, you will still need to do this when it is not in use. Do you have a question you’d like us to ask Hank for you? If you do, you can comment here, or post it to our Facebook page!
