First Winterization, 2011 Jayco JayFlight G2 33RLDS.
I feel that I have adequately winterized my JayFlight G2 33RLDS for the first time but have a few concerns. I have drained both of the fresh water holding tanks along with the gray and black holding tanks. I isolated and bypassed my Atwood hot water heater with the provided valves and drained the tank. At first I left the hot water heater drain plug out. While towing from storage to my residence for final cleaning I noticed water splashing out of the hot water tank. I have read on this forum that there are two quarters of water that remains in these Atwood hot water heaters and that there is no need for concern, so I am not too concerned about that. I also read that it might not be a bad idea to return the plug to its proper location to prevent insects from making themselves at home up in there so I have done so. I turned off the main water supply to the electric pump from the fresh water tanks. I needed to do that in order to get the pump started with the antifreeze. I have gone as far as to purchase a city water hand pump and pumped from there as well to ensure everything has antifreeze in it, hot and cold water pipes at the kitchen sink, bathroom sink, inside and outside showers along with the pee traps and toilet.
I found two small valves in the bath room cabinet next to the inside shower located under the plumping for the outside shower. There are two pipes that go out of site under the floor. Not sure where but I turned them off as well. I am concerned about these valves and the pipe I can’t see because of their location and the under belly insulation and whether or not I should have turned them off. I am also concerned if I should reopen the main water supply to the electric pump. Looking for a little advice on these two items and anything that I may have missed.
