How to Winterize Your RV: 9 Easy Steps

You can easily winterize your RV by yourself as it’s an easy task. But, irrespective of whether you or an expert RV technician winterize the RV, the crucial thing is preparing your RV for the cold. So, you should learn the easy 9 steps to complete this winterizing job.

RVers own different types of RVs. Thus the winterizing process is not the same for all RVs. So the best task is to follow the owner’s manual before starting the process of your RV winterization. However, you may need to perform additional winterize steps as some RVs consist of additional components. The extra parts in RV include an ice maker, washing machine, or dishwasher.

Step 1: Dump and Drain

Start the winterizing process by dumping and draining the grey and black water holding tanks. Ensure that both the grey and black water holding tanks are empty and clean.

Step 2: Drain your RV’s freshwater tank

Step 3: Clear out your RV line’s water

For clearing the water in the RV lines, follow the simple steps below:

  • Prevent the going back of water into the RV’s holding tanks by placing a bowl below the faucets
  • Open the faucet’s cold side by turning on the water pump as long as there is a lack of water or no water in it.
  • Close the faucet’s cold side and open the faucet’s hot side as long as there is no more water
  • With every shower and sink, which are RV’s inside and outside, you have to repeat these above steps.
  • Now under the low-point drain valves, place a bucket.
  • Open these drain valves and remain them open.
  • Locate the water heater’s pressure release valve. If there is an anode rod with the water heater, you can assist in the draining process by removing the rod after pressure release.
  • If there is a black water flush, you can blow out the black flush inlet and city water line.
  • If any faucets remain open, close them.

Step 4: Use the water heater’s bypass valve and then bypass the RV water tank

Step 5: Use RV Antifreeze to Protect the Lines

From the converter kit of your water pump, find out the siphon tube and then insert the line into the pink RV antifreeze’s one-gallon jug.

Note: Already, many new RVs may have the installed water pump kit and siphon tube for installation. But if you lack this kit, you should first disconnect the line with the fresh water tank. Then connect the water pump inlet’s box to the pink RV antifreeze jug.

Step 6: Through the system, push the RV antifreeze

  • Turn the water pump on. As soon as flowing the pink RV antifreeze is visible, you should instantly close all low point drains.
  • Until you see the pink RV antifreeze flow through the low point drain, outside and inside of the RV, you should open the toilet valves, faucets, and showers.
  • Repeat this entire process for the faucet, both hot and cold sides.
  • For releasing the faucet’s built-up pressure one more time, you should open the faucet and close the water pump.

Step 7: On the RV’s outside, through the water intake line, push the pink RV antifreeze

  • A small-cap covers the inlet. At first, take it off and remove the inlet’s small screen cover
  • Use a screwdriver to push on the valve as long as you don’t see the antifreeze
  • Replace both the cap and the screen

Step 8: Drain the siphon tube

  • Keep the tube in your pink RV antifreeze bottle but keep it over the liquid.
  • Start the water pump to help drain the left fluid from the tube to the lines. If there is left any remaining antifreeze in the box, you should lift the hose or turn the sink on to help its drain.
  • Wipe down it by stopping the water pump and then sow the siphon tube

Step 9: Use the P-traps to pour the RV antifreeze

  • In your sink, shower, or toilet’s p-traps, pour the pink RV antifreeze’s half cup amount
