Questions & Answers

Why can't a regular air compressor be used with this adapter? My desire is to install a PVC or copper extension line to my existing plumbing with a block valve, and a female end to use this on each of my summer rentals to make winterization easier.

      All brass fittings and was easy to use. I recommend looking up the Youtube video when assembling for the first time. Was able to use my 400P-RV pump to winterize my Fifth Wheel. A quality product and reasonably priced.

      Failed to hold pressure
      Per the instructions I set the regulator to 30psi. As soon as I tried to connect the regulator to the RV's blowout plug the pressure dropped to zero. Multiple attempts. 100% failure rate.

        Seems to be good quality and worked well for me the first time I used it. Pressure adjustment knob is a little clunky feeling but it worked so not an issue.
