    • Very fast shipping

Just as described, works great.

    • Easy to use!
Very simple to assemble. Watched a couple of YouTube videos before using. Set my compressor outlet pressure to 45 psi. Attached my water hose pressure regulator prior to using. Started with emptying hot water tank and opened low point drains before moving inside to the pump inlet hose per other’s recommendation. Blew out water from the pump after learning there’s a check valve in there preventing water from back flowing. Followed the directions of opening the furthest valves one at a time allowing water to blow out. Moved out to the city water hook up and again followed directions of opening valves furthest from the water supply including outdoor shower and exterior water spigot. Opened the fresh water fill and blew that clean ensuring that inlet valve is clear. Afterwards opened all faucets and poured about a cup of rv antifreeze into the drain ptraps and toilet. All in all took about 15 minutes. I really prefer this method as we use our trailer throughout the winter and really don’t want to have to clean out antifreeze from the pipes every time we use it. Where we live the nighttime lows dip into the low teens with the rare single digits with daytime temps in the mid 40’s to low 50’s. ... show more

    • Winter Water
Winterizing your camper needs more then just adding the antifreeze. You must blow out all water in pipes and this does the job. No more freezing pipes.
