Review on Winterize Your Trailer with GOLDPAR Blowout Adapter: Say Goodbye to Frozen Plumbing! by James Broome

I recently disinfected my RV for a trip to a warm location in early April. As expected, the weather in Indiana dropped below freezing a few days before we left. Instead of redoing the antifreeze, I used this adapter to blow air out of the pipes. It worked perfectly with my air compressor. Check your owner's manual, keep your PSI down (mine's around 40), and turn on the faucets. Maybe I'll do that next fall, who knows.
