RV Winterizing to Protect the Water System


With the beginning of fall, it’s time to decide if your RV camping season is over. Parking your recreational vehicle for the winter or RV winterizing, as it is better known as, requires some preventive measures to make it ready for next spring. And preparing the water system to protect it from freeze and damage is one of the most important factors of RV winterizing. The following tips will help you to protect your water system of your recreational vehicle during the harsh winter months.

To begin your RV winterizing drain the fresh water tank of your recreational vehicle.  Now drain the hot water heater. Next, you need to dump and flush the gray and black water tanks; also, remember to leave the gray water valve open.  You will need a compressed air adaptor and screw that into your recreational vehicle’s fresh water inlet. While applying compressed air, make sure the pressure is less than 20 lbs/sq inch.

Now open each faucet and make it one valve of your recreational vehicle at a time. This helps the compressed air in forcing the water out of the RV’s inlet. In addition, don’t forget the toilet and shower of your recreational vehicle.  In addition, you need to remove the hot water tank’s drain plug so that the compressed air can blow out the remaining water. Once all the water is removed, you need to reinstall your recreational vehicle’s drain plug. Then remove source of compressed air and the adapter.

Look for the by-pass valve of your recreational vehicle’s water heater and close it. Also, remove the water line running from the fresh water pump to the fresh water tank. Insert RV antifreeze at the end of the water line. Now start the vehicle’s fresh water pump to run for a few minutes, until it sucks the antifreeze. When the pressure in the water system builds up, it will stop automatically. Once again open the valve of every faucet and until the red RV antifreeze appears. Shut the faucet. Finally remove the water line from the jug containing RV antifreeze and reattach the same to your fresh water tank.
