Ospreybob Posted March 6 Share Posted March 6 Water leaks out of the city water connection when nothing is connected to it and we run the pump. I am thinking that the check valve in the city water line is not working. Anyone have experience with this problem? Can I get to the check valve so it can be replaced? Thanks in advance for your advice! Bob Link to comment Share on other sites More sharing options...
rich.dev Posted March 6 Share Posted March 6 Yes it might be check valve, but look into the inlet of your fresh and city water connectors, you will see a hex. (I think its 1/2”) fitting like the below piture, tighten that hex. fitting and hopefully that will solve your proble. . 3 2023 Elite II, Hull# 1386, Lithium Platinum Package (640AH, 400W Solar, 3000W Xantrex Inverter) Truma water heater & AC TV: 2024 Silverado 2500HD 6.6L 10-Speed Allison Link to comment Share on other sites More sharing options...
jd1923 Posted March 6 Share Posted March 6 It would need the hex tightened when leaking upon hookup. Since the City Water is leaking when running the pump from the Fresh Tank, it must be the backflow preventer (check valve). You have no sig, so can't tell hull number, but for ours in 2016 these are in the back of the basement/trunk (see pic). 3 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

Ospreybob Posted March 6 Author Share Posted March 6 Thanks, folks, for all the great input. Much appreciated! I'll try to tighten the hex as a first step. I appreciate the large bolt suggestion! We own hull 747. If it is a bad check valve, is the valve separate from the city water fitting or integrated into it? Bob Frank Link to comment Share on other sites More sharing options...
