Question: 1 / 400

What happens to all water during the winterization of an entire RV water system?

It is completely treated

It is replaced with antifreeze

During the winterization of an entire RV water system, all water is replaced with antifreeze to prevent any freezing damage that could occur in the plumbing and appliances. This process is essential in cold climates where temperatures can drop below freezing.

The antifreeze is specifically formulated for RVs and is safe for use in potable water systems, ensuring that the pipes and fixtures do not freeze, crack, or burst when temperatures drop. By introducing antifreeze instead of just trying to drain the water or leaving it in the system, the risk of damage is significantly reduced. This practice allows the RV to be protected effectively during periods of non-use in winter.

Other approaches, such as merely draining the system, may lead to residual water that could freeze and cause issues, which makes replacing water with antifreeze the most reliable and thorough method for winterization.
