How To Winterize Your RV
Winterization is an important component of the care and upkeep of any seasonal vehicle, like an RV. Follow our tips for winterization to ensure that your RV is protected during the cold months and ready to go when it's warm again!
First, drain all of the water from the water holding tanks. Then, remove the water from the water heater. Look for a drain located on the bottom of the heater.
You can get a blowout plug from most RV parts stores. Hook this plug up to your RV's city water inlet, and hook that up to your air compressor. Blow air into the system at around 30psi. Then, go around your RV, opening each water valve one at a time until all the water is blown out of the lines. Do this for both cold and hot water lines. Don't forget to flush the toilets.
Once you are finished, turn off the compressor and take off the blowout plug. Open a faucet to release the pressure in the system. Now it is time to pump antifreeze into your lines. The easiest way is to buy a valve that allows your pump to pump the antifreeze straight from the bottle into your system. You can get these at an RV parts store. Depending on the type of RV, you may need a few gallons. As you pump the antifreeze, open the faucets one at a time to see if antifreeze comes out. Once the antifreeze comes out of any of the faucets, you know it is in the system thoroughly.
To finish, pour a cup of antifreeze down the drains. Pour a cup or two into the toilet and flush it. Now, your system's lines should be protected from the cold. Finish the winterization by covering your RV to protect the exterior from the elements!
