How to Winterize RV Water Lines

As winter sets in, it becomes imperative for RV owners to prepare their vehicles for the cold weather. One crucial aspect of this preparation is winterizing the RV water lines to prevent freezing and potential damage. Below, we will guide you through the process of winterizing your RV water lines, ensuring they remain in good condition during the colder months.

1. Gather the necessary tools and materials:
Before starting the winterization process, gather the following items: non-toxic RV antifreeze, a water heater bypass kit, a water pump converter kit, a wrench or pliers, a water pressure regulator, a hose, and a bucket.

2. Drain the water system:
Begin by draining the entire water system. This includes the fresh water tank, hot water tank, and all water lines. Open the RV’s faucets, both hot and cold, and allow the water to completely drain out. Don’t forget to drain the water heater as well.

3. Bypass the water heater:
To prevent antifreeze from entering the water heater, install a water heater bypass kit. This will allow you to skip this step during winterization, saving on antifreeze and simplifying the process.

4. Prepare the water pump:
Locate the water pump in your RV. Remove the inlet hose and attach a water pump converter kit. Place the other end of the kit into a container filled with RV antifreeze. Turn on the water pump and open each faucet, one at a time, until the antifreeze runs through them. Repeat this process for both hot and cold water lines, including the toilet and shower.

5. Flush the toilet:
To ensure the entire system is protected, flush the toilet until antifreeze is visible in the bowl. This will also help protect the seals and valves from freezing.

6. Clean the exterior:
While winterizing the water lines is vital, it’s also essential to clean the exterior of your RV. Remove any debris, dirt, or grime that may have accumulated during your travels. This will help protect the vehicle’s exterior from potential damage caused by the winter elements.

7. Store the RV:
Once the water lines are winterized and the exterior is cleaned, find a suitable storage space for your RV. A covered or indoor storage area is the best option, but if that’s not possible, consider using an RV cover to protect the vehicle from snow and ice.

No, once you have winterized your RV water lines, it is not advisable to use the water system until it has been properly de-winterized in spring.

6. Can I leave water in my RV’s water heater during winter?
It is best to drain the water heater to prevent freezing and potential damage. Install a water heater bypass kit to simplify the winterization process.

7. Should I keep the RV water pump on during winter?
It is recommended to turn off the RV water pump during winter to avoid any potential issues or damage caused by freezing temperatures.

By following these steps and taking the necessary precautions, you can successfully winterize your RV water lines, ensuring their longevity and preventing costly repairs due to freezing. Remember to perform regular maintenance checks throughout the winter season to ensure everything remains in good working order.
