Why Winterize Your RV?

It’s no secret winter in the North West can get cold, what most people don’t know is why they should winterize their RV. This short article will cover the potential hazards of not winterizing your RV and give you a thorough understanding of when to take advantage of our winterization and de-winterization services.

What Is RV Winterization?

An RV Winterization is a service that RentForFun RV provides to keep your RV’s fresh water and waste water systems from freezing up and causing damage to your RV. The process is designed to remove water from all of your water systems including:

  • Fresh Water Tank
  • Water Lines
  • Water Heater
  • Water Pumps
  • P-Traps
  • Waste Tanks

How Is Winterization Done?

A typical winterization is done one of two ways:

1. Blow-Out Method

The blow-out method is done by first draining the water out of your RVs fresh water tank, and water heater. It’s then hooked up to a pressurized air tank and every line is cycled with positive air pressure blowing the water into the waste tanks. The final step is done by draining your waste tanks and then adding coolant to every drain to ensure any residual water is treated with chemical.

2. Anti-freeze Method

The anti-freeze method is done by draining water out of your fresh water tank, and your water heater and then treating your fresh water lines with anti-freeze solution to ensure they don’t freeze.


When spring comes around and the winter temperatures normalize above freezing it’s time to undo the winterization. The process of de-winterization is simply the reverse of winterization. The drain points are plugged, fresh water lines hooked up and fresh water filled to test for any leaks.
