Water Backflow Check Valve?
I have not used my freshwater tank since I bought my trailer because the first time I tested it I noticed I had a cracked filter and the pump would not pump water. At the time I was doing that testing, the trailer was hooked up to the campground faucet with the water turned off.
I finally replaced the filter and put in a new pump at the same time (quieter, variable flow, etc) but quickly ran into a problem. This time, while testing, I was not hooked up to campground water I just left the outside hose dangling and unhooked while checking out the system. When I turned on the pump, everything worked fine except that the pump, along with feeding the interior faucets, was pumping water out of my freshwater tank through the inlet hose where I hook up campground water. I figured there must be a check valve or switch somewhere in the system that is supposed to prevent that.
I have a 1986 LIMITED 34 foot Airstream
Anyone know what to do about this problem, if there is a check valve, where is it, etc?
Thanks
