How to dewinterize your rv

0 Comment




As the snow thaws and you begin making plans for summer trips the first step is to prepare your RV.  Over the winter you’ve protected your waterlines with RV antifreeze.



Over the winter it’s possible leaks have developed. As we clear the waterlines keep an eye out for any leaks from cracks or incorrect hook ups.

Begin by filling the fresh water tank so we can fully flush out the lines. This will clear antifreeze and stale tank water. A product like Tank Fresh can also be used (1 cup for every 30 gallons) to help flush the waterlines.

Second prepare your water pump by securing all plumbing connections. Turn on the pump on briefly to begin pushing fresh water through the lines, while watching closely for any leaks then turn the pump off.

If all the connections look tight go ahead and start fluting the antifreeze out by turning the pump back on. You’ll want to run all your taps including: sink hot and cold water, the shower hot and cold, flush the toilet. Continue this until the water runs clear. During the process keep an eye on the pump to ensure no leaks begin.



Once you see the water running clearly fill the water heater once again. Look to see if your water heater has a bypass kit, if so put it back into the regular position. It’s important to only switch the bypass once you’ve run all the hot water taps until clear to ensure you’re not filling the hot water tank with antifreeze.

Place the plug back in the hot water heater and run the tap hot for 5 minutes in the kitchen. You may hear the tap spit and make noise as the waterlines refill as the hot water tank is also filling. Once the tank fills up you’ll get a steady flow of water. The tank is likely 6 gallons so expect it to take some time.



During the winter seals have potential to dry out or or move due to dirt or blockage. As you hook up your RV to city water look for a clean seal on your check valve. If water begins shooting out turn off the pump. This means your check valve has become unseated. You’ll need to take off the screen from the hookup and try to push the check valve back into place. If it does not reseat then you’ll need to replace the check valve.

As you prepare to dewinterize your RV be sure to check the weather to ensure temperatures will remain above freezing. There’s potential for burst pipes if temps fall agains once you’ve cleared all the antifreeze.

Now that the weather is warm and you’ve dewinterized it’s time to enjoy your RV.
