A change of idea that makes it less work. For those with an older camper prior to the city water hose fixture (only gravity fill). The photo below is 4 parts: $7 for a replacement cap (a forstner bit 3/4" hole cut in top), a pipe thread waterline fitting, a male pipe thread to female hose thread adaptor, and the hose thread air pressure fitting. I used 5 minuter epoxy to join cap to pipe fitting.
Simply unscrew water cap on camper, put this cap on and use compressor at 30lbs to blow out water in system out the rear petcock drain.
Sure hope this works as it is getting cold here and I want to winterize the water tank. We leave in January for the southwest. My hope is to once far enough south, fill the 20 gallon water tank for 3 weeks in Big Bend. We will also carry suitcase water. After the three month wandering around we head back to the Northeast and I can use this cap with my onboard compressor to blow out the tank should the temps still be below freezing. It is mostly for when we are out in the desert I want to have a lot of water.
yup it worked!
