Lippert’s Floe 636 automatic winterizing system simplifies the process — a lot. First designed and distributed in Ireland for caravans, the system is basically a small air compressor system with a pressure switch and isolation valve that is permanently built into the RV’s plumbing system.
Installation is straightforward with a few changes in the procedure depending on the RV, so we won’t go into all the details of installing it in our 2015 Montana. However, it’s simple, and there are videos online that demonstrate how it’s done (including this one by Lippert: support.lci1.com/videos/floe-integrated-water-drain-owners-video). It’s entirely up to you how sophisticated you get with the installation, but the basics include a 12-volt DC connection and a plumbing fitting. Everything you need is included in the kit.
The system, which retails for about $200, works as advertised and is quite a convenience. It can be found at your favorite RV store or on Amazon (https://amzn.to/2ZiQyjS). Northerners who drive South to flee winter’s cold weather will appreciate the ability to dewinterize on the road, and then when returning, continue to use plumbing normally until they get closer to winter weather.
