Winterizing tips for motorized RVs

Your water system is the most susceptible to damage during the winter months. If any water is left in the lines it can freeze, expand and rupture your pipes and hoses. To protect your rig from this unwanted damage, you will want to run RV antifreeze through your water system when winterizing.

RV Antifreeze

It is important to note the two different kinds of the antifreeze out there. RV Antifreeze is very different from the antifreeze that is put into the radiator of your car. RV Antifreeze is typically a non-toxic pink fluid and is used to protect your RV’s plumbing system. DO NOT get RV Antifreeze confused with the toxic antifreeze that goes into your car.

Cleaning the Tanks

Before you store your RV for the winter you will want to clean out all the tanks. It is best to start with the black tank, then your gray tank and lastly your fresh water tank. You will want to dump, clean, sanitize then flush with more water to make sure you clean everything out.

Emptying the Lines 

Before beginning, make sure your water heater is turned off and has cooled down. Once it’s cooled, empty it by opening the pressure valve and taking out the drain plug. Then you will want to go inside your rig and turn on all sinks, showers and toilet valves and run until no more water is coming out. Once you’ve cleared all the water out of your system, turn off your water pump. Next step, move valves to the “Sanitize/Winterize Lines” position and make sure the low point drains are closed for the antifreeze to siphon through the lines. Turn on the pump and open all your faucets again one at a time until you see antifreeze coming out.

The Battery

Make sure you protect your motorhome’s battery by disconnecting the negative cable. If left connected while in storage, your battery could drain resulting in a shorter battery life span.

General Winterizing Tips

  • Remove any food from your rig that can spoil or attract unwanted critters
  • Thoroughly clean your RV’s interior
  • Clean and store the sewer hose
  • Before storing is a good time to wash and wax your RV
  • Examine all exterior doors and window seals
  • Keep your RV out of direct sunlight if possible
  • Check plumbing vents, roof vents and air condition shrouds

As always, if you need assistance, please contact your local RV dealer.

 WARNING

Please note that repairs due to freezing are not covered under the terms of the Motorized Limited Warranty. Also, automotive antifreeze (ethylene glycol) and windshield washer antifreeze (methanol) are poisonous. Never use these products in your fresh water system. These products are harmful and may be fatal if swallowed.
