This is my third winter as a travel trailer owner and I ran into an issue that I have not experienced before and I was hoping to get some help from the experts.
I went through the typical winterizing process of by passing the hot water tank, pulling the drain plug on the hot water tank, etc. When I got to the step of putting antifreeze into the water lines, I noticed the water pump was not drawing in the antifreeze. I have a bypass line that sucks the antifreeze into the water system and I triple checked the bypass valve was positioned correctly. It is worth noting that my TT is connected to a city water hookup at a campground that has shut the water off for the winter. Therefore there is no water supply and the fresh water tank is empty. I was under the impression that as long as the antifreeze bypass line was hooked up, I wouldn't need water in the system but maybe that is my mistake. I think my next step is going to be taking a bunch of jugs of water to the campground to fill the fresh water tank to see if I can get the pump to start pumping again, but if anyone else has any thoughts it would be greatly appreciated.
