Question:
Is it possible to connect a “quick connect “ attachment so it can be used to blow water from RV lines?

Hey Kim,
We do have a piece from Camco called a blow-out plug, # CAM36143. This would install in your city water inlet port and then you could hook your Air Lift compressor up to blow out those water lines. The compressor itself does not have an adapter that would do so. You'd simply screw it into the city water inlet and attach the compressor like a normal air fitting.
What kind of trailer are you wanting to use this on/

Yes I have used this quick connect fitting many times. Works great. My RV manual recommends setting the regulator down to 40 psi. I open each fixture individually to clear out water then use RV antifreeze for added protection from freezing. Definitely a must have for winterizing.

The blow out plug for compressor quick connect to City Water port on the trailer works well to blow out the lines for winterizing. Just set the compressor to not exceed 50 psi or put a pressure regulator on the line as well because the plumbing in the trailer is not designed for high pressure...make sure all faucets and valves are open when blowing out the lines.
