The first step in winterizing your camping trailer is to completely drain the water system. This includes the fresh water tank, water heater, and all water lines.

Draining the Fresh Water Tank

1. Locate the fresh water tank drain valve. It is usually underneath the tank.
2. Place a bucket under the drain valve.
3. Open the valve and allow the tank to drain completely.
4. Once drained, close the valve.

Draining the Water Heater: Winterizing RV Water Heater

1. Turn off the water heater and allow it to cool completely. Never drain a hot water heater.
2. Bypass the water heater if you have a bypass kit. This will prevent antifreeze from filling the water heater tank.
3. Locate the drain plug on the water heater. It’s usually at the bottom of the tank.
4. Remove the drain plug.
5. Open the pressure relief valve at the top of the water heater to allow air in and help the water drain faster.
6. Allow the water heater to drain completely.
7. Replace the drain plug, using Teflon tape to seal the threads.

Draining the Water Lines

1. Open all faucets, both hot and cold, including the shower and outside shower.
2. Locate and open the low point drain valves. These are usually located underneath the trailer, near the water lines.
3. Allow all water to drain from the lines.
4. Flush the toilet to remove any remaining water in the bowl and lines.

3. Bypass the Water Heater

If your RV has a water heater bypass kit, now is the time to use it.

1. Locate the bypass valves near the water heater.
2. Turn the valves so that the water heater is bypassed. Typically, this involves closing the inlet and outlet valves and opening the bypass valve.
