When it comes to winter storing an RV, protecting the plumbing system is a top priority to avoid costly repairs. Many RV owners traditionally blow out their water lines to remove any remaining water, but this method doesn’t always guarantee complete protection from freezing temperatures. Using RV antifreeze designed specifically for potable water systems is a safer and more effective solution. Unlike standard antifreeze, RV-specific antifreeze is non-toxic and formulated to prevent freezing while protecting seals and hoses from damage.

Blowing out the water lines can leave residual water in small nooks and fittings, which may freeze and expand, causing cracks and leaks. In contrast, RV antifreeze fills the entire plumbing system, providing a consistent barrier against freezing throughout all pipes and tanks. According to RV experts, antifreeze is recommended especially in climates experiencing prolonged freezing conditions, as it offers greater peace of mind and reduces the risk of winter damage that can lead to expensive repairs. For comprehensive guidance on winterizing your RV plumbing, many RV lifestyle resources and manufacturers suggest antifreeze use as the most reliable method.

Additionally, properly winterizing your RV’s water system with antifreeze can also prevent corrosion and buildup in your pipes during storage. This helps maintain the longevity and performance of your plumbing components when you’re ready to hit the road again. Whether you are a seasoned RVer or new to the lifestyle, understanding the benefits of using RV antifreeze over simply blowing out your water lines can save you time, money, and hassle in the long run.
