Winterize the Plumbing of Your RV Water System

Winterize the Plumbing of Your RV Water System

Here are the steps to winterize your camper:

Drain and flush black and gray water tanks

Locate the tank drain valves and open them to drain the fresh water tank. Let the water flow out until it is all gone.

Use a long hose (at least 12 feet) to extend away from your camper for proper drainage.

Once drained, you can begin flushing your tanks with fresh water from the city connection or a garden hose. Flush each tank until the water runs clear.

Prepare, drain, and bypass the water heater

It is important to take this step. Turn the water heater on and let it reach a temperature of at least 120°F (49°C). Once the water is hot, turn off the power switch or disconnect from shore power if connected.

Drain the freshwater tank and low point drains, bypass the freshwater tank

Locate the low point drain and open it to drain the freshwater tank.

The water will flow until it is all gone. Use a long hose (at least 12 feet) to extend away from your camper for proper drainage.

Flush the water lines with antifreeze using the water pump converter kit

Once you complete the draining , water lines will be drained. Fill the fresh tank with RV antifreeze to help in winter storage. A water pump may help. Some RVs have a water heater. Turn on your hot water faucet to allow the antifreeze to flow through all the lines. Let the water heater run for about 10 minutes before turning off the faucets. Remember to remove any inline water filters. This is because antifreeze can damage them.

Blowing the Water Lines Out with the air compressor

Once you pour antifreeze in all the water lines, you can use an air compressor to blow out any remaining water from the water heater. Connect an air hose to a compressor and attach it to the city connection or low-point drain line. Reduce the pressure gradually until the faucets stop producing water. Turn off the compressor and unhook the air hose once all of the water has been removed.

Final plumbing winterization steps

Once you completely drain water lines, it is time to winterize the plumbing of your RV water heater system. Open all the faucets and shower heads to allow the antifreeze to run through them. With all the drain valves open, pour RV antifreeze into each drain until it comes out of the nearest faucet or shower head.

Finally, seal all drain valves to prevent water from entering the lines during winter months. Your camper is now ready for storage.

Your vents are an important place to check for pests during the winter. First, ensure your vents are covered with a screen or mesh to prevent critters from getting in. Then, if you have any gaps, seal them off with foam insulation strips or caulk. You should also be aware of where the vents lead and ensure those access points are sealed.

If pests have entered the vents, a professional should be contacted. They will be able to safely remove any pests and provide advice on how to prevent them from getting back in.

Inspect your vents regularly throughout the winter season and seal them off properly. In this way, you can rest assured that your camper is protected from unwanted visitors


You need to check the roof of your camper for any cracks or holes that pests may use to enter. If you find any, seal them up with caulk. You can also use a pesticide spray on the roof to help keep out pests. Follow all safety instructions when applying the spray and wear protective gear if necessary.

Doors and windows

You must check all windows and doors to ensure the seals are in good condition. Look for broken or cracked seals that may allow pests to enter your camper. If necessary, you should replace them with weather-resistant door and window seals.

Exterior spraying

You can also spray your exterior walls with a pest repellent to keep insects away. It is especially important if you store your camper outside during the winter. Again, check the manufacturer’s instructions carefully, and apply the repellent in a well-ventilated area.
