...with 25 PSI of air pressure in the lines 😁 Yesterday was sunny and a whopping 50° outside, so I decided to check out the motorhome for any damage done by our sub freezing temps (mid 20's for five hours). First I connected the MH to our water line and checked for leaks, nothing, phew. Then I disconnected the water line and hooked up my air compressor to blow out all the internal lines of water. Did this so that all the lines were blowing air, but knew the hot water tank wouldn't be fully drained. So forgetting that the compressor was still running, I started unscrewing the drain plug. Suddenly, the plug blew out of my fingers and I was deluged with cold water😢. The plug disappeared somewhere into the bushes next to the RV. Duh I thought, still had air pressure. So anyway, a new plug arrives tomorrow but I can rest at ease if the temperature drops knowing that all the lines are cleared of water. Still a small amount in the fresh water tank, gray and black tanks, but I'm not worried about them. We rarely drop below freezing for more than 5 or 6 hours during the winter, so no need to fully winterize.
