What You'll Need:
- Non-toxic RV antifreeze
- Cleaning wand
- Water heater bypass kit (your RV may already have one)
- Water pump converter kit (if your RV does not already have one)
Empty the holding tanks. Make sure to go above and beyond just draining the tanks, use your black tank flush to completely get any gunk out, or use a cleaning want from inside the RV to blast out any unpleasantness so that it doesn't sit around all winter.
- Get all the water out. Sometimes draining the system just isn't enough! Use an air compressor, but keep that PSI low, around 30 - 50 psi to avoid blowing out the water lines. Make sure that all the water faucets are open, or you could have an expensive and explosive situation on your hands! Don't forget about the water heater either, as it'll need to be drained before winterization.
Get it pumping. Time to get that antifreeze into your RV's system! After bypassing the water heater, use the line that connects to your fresh water line and stick it right into the antifreeze bottle. Ensure that you've closed all the faucets that you opened earlier before turning on the water pump. This will get the water system to start sucking up that pink antifreeze into the system like a toxic strawberry smoothie!
- Let it flow! One by one, open each faucet until the antifreeze starts to flow out, then closet them up again! Don't be afraid to bust out in your parody version of Let It Go, and your water lines won't be Frozen this winter. Don't forget to get that antifreeze flowing into the toilet too!
