NDBirdman Posted May 6, 2018 Report Share Posted May 6, 2018 Filled up the freshwater tank today in prep for an outing. Turned on the pump to check out the system/sanitize it. Got water everywhere we are supposed to with one exception. With the pump running, water is blowing out the city water connection. There is a hard rubber plug in it but it blows it out. I followed the city water line as much as I could, there is no valve to shut the line off preventing it from back flowing out the city water hose connection. It looks like the line goes in and connects to camper water supply right after the on board pump. Is there supposed to be a check valve or shut-off valve before the pump? There isn't one.
