When temperatures drop below freezing, any water left in your RV's plumbing can expand and cause costly damage. Winterizing takes an afternoon and saves a lot of headaches in spring.
- Drain the fresh, gray and black tanks, then flush the black tank.
- Drain the water heater. Turn it off first and let it cool.
- Bypass the water heater so you don't waste antifreeze filling it.
- Pump RV-safe antifreeze through the lines until pink fluid runs from every faucet, shower and toilet.
- Pour a cup of antifreeze into each drain to protect the P-traps.
- Remove or maintain batteries, close the vents and cover the roof if storing outside.
