Review on Hotop Winterize Blowout Connecting Winterizing by Robert Viher

As the cold weather approached, I needed to unclog my RV's water lines to keep them from freezing and damaging my plumbing. to drain my lines (open drains at low point, open faucets, water pump on, etc.). went home and did it again. By hooking this up to my air compressor, I was able to drain a few more gallons of water from my lines - I was in shock. Worth the price to save on expensive repairs! You have to tighten the parts (easy to do) and I can add some teflon tape for a better airtight seal, but I only push 30psi through my lines so a small leak isn't a big deal
