Drain the fresh water tank – To do this, simply open any faucet in your RV and let it run until the water stops. This is a crucial first step in winterizing your RV because it not only removes water that could potentially cause your pipes to freeze and burst but also saves you from getting sprayed when you open the drains or unscrew the plug on your water heater.
Open low point drains and drain any water out of them – Keep in mind that they may be difficult to find, but you need to make sure you find them – draining the water out of your low point drains is very important when you winterize your RV.
Turn your electric water heater off.
Drain hot water heater.
Remove all the water from your water heater and drains – To do this, hook up compressed air to the city water inlet. Blow all of the water out of the water heater and low points .
Remove the rest of the water from your RV – Close the water heater and low point drains. Open all faucets while they are under pressure to blow all water out of the faucets, tubs, showers, toilet and outside shower.
If you have a filter, remove it and install a filter bypass – This will prevent antifreeze from ruining the filter. If you plan on replacing the filter you can skip this step and leave the filter in place.
Add antifreeze to your RV – Find the water pump and disconnect the suction side of the pump. Install a hose with fitting onto the pump and insert the other end of the hose into a jug of antifreeze. Make sure you use RV antifreeze – never, never, NEVER use automobile antifreeze when winterizing you RV.
If you have an antifreeze outlet on the exterior of the trailer then connect a hose to that outlet and locate the valve off of the pump and turn that valve so it will suck out of the hose and not the tank
Turn the bypass valve on the water heater to the bypass position – If your water heater does not have a bypass valve, you may try either of these two options: either fill the water heater with antifreeze (it will require about six gallons) or disconnect the lines from the rear and install an inline fitting to manually bypass.
Move antifreeze through your whole system – Turn on the pump and run antifreeze through both the hot and cold side of all faucets in the sinks, through the shower faucet and hose, and through the toilet and outside shower. This requires about 1.5 gallons of antifreeze.
Unhook the pump and reinstall the hose to the tank or if equipped with exterior outlet then disconnect the hose and turn valve back to normal postion
Pump antifreeze into the city water fill – Use a hand pump to protect the check valve.
Pump antifreeze through the black tank rinse to winterize the check valve.
Clean all sinks, tubs and showers thoroughly – antifreeze can stain!
It's important to clean the RV out completely before you store it for the winter so there is less chance of rodents getting into the RV. It's also a good practice to remove the batteries from the unit and place in a dry cool area and charge every 30 days. If batteries are not removed they will freeze and split over the winter and you will need to buy new batteries in the spring.
Properly winterizing your travel trailer RV will ensure years and years of camping memories and a fully reliable rig!
