The Floe 636 is a permanently installed, 12V-powered drain-down system that uses low-pressure compressed air to push water out of every line in your RV plumbing system -- hot and cold -- in just a few minutes. Forget the antifreeze mess or hauling a separate compressor hookup outside. The Floe lives inside the rig and does the work at the push of a button, whether you are winterizing for the season or purging stagnant water after a long sit.
Traditional RV winterization means either pumping antifreeze through every line or wrestling with an external blow-out adapter and a shop compressor. The Floe 636 eliminates both. It connects directly to your main cold water supply line via the included T-connector and uses a built-in 12V compressor to deliver a controlled 15 PSI air charge -- enough to move water through the lines without over-pressurizing fittings or valves.
The process is simple: connect the system once during installation, then whenever you need to drain down, power it on and open each faucet -- hot and cold -- one at a time. Water is pushed out efficiently and completely. Independent testing shows the system removes up to 99.95% of bacterial buildup from inside your plumbing lines, making it just as useful for a mid-season sanitation flush as it is for end-of-season winterization.
T-connector included for tapping into your main cold water line. No external hookups needed after installation.
Compressed air purge clears stagnant water and the bacteria that colonize it -- useful after storage, not just at winterization.
Low enough to protect your fittings and valves, effective enough to fully evacuate lines on a typical single-axle or Class A coach.
Certified for contact with potable water. Safe for use in drinking water plumbing systems in RVs, boats, and trailers.
Once installed on your cold water main with the included T-connector, the Floe 636 draws 12V power from your RV's house battery or shore power system. When activated, the internal compressor builds pressure and introduces air into the plumbing system. You then open each faucet -- starting at the fixture closest to the pump and working outward -- until water stops flowing and only air discharges. Repeat for hot lines by opening the water heater bypass if equipped. The entire process typically takes under five minutes on most coaches.
No antifreeze is needed with this method (though some owners in extreme climates add a small amount to P-traps as extra insurance). The system can be used as frequently as needed -- after a camping trip, before a storage period, or any time you want to flush old water from the lines.
The Floe 636 mounts to a wall or cabinet in your wet bay or utility compartment. Overall dimensions are 7.87 inches long x 6.69 inches high x 2.36 inches deep, and it weighs 1.8 lbs, so it fits easily in tight spaces. The T-connector included allows you to splice into the cold water main without cutting out a pipe section -- a standard push-fit or compression T depending on your plumbing type. 12V power is wired to a convenient switched circuit or directly to the house battery with a fuse.
Compressed air has always been one of the most efficient ways to remove water from pipes. We’ve just made this process more convenient and accessible. Instead of paying somebody to perform this task for you, Floë makes it easy to drain your fresh water system, the moment you need to.
In no time, you can get back to enjoying water that’s ready for your family, friends, and pets to use. Or you can prep your RV, trailer, or boat for winterization — preventing frost damage to your pipes and fresh water tank. Whether you’re operating with a 12-volt power supply or you have access to the main AC outlet, both the Floë 636 and Floë 868 are easy to install and even easier use.
