Blue hose dripping water undercarriage

[eikaun@gmail.com]

Hello, we own a 2015 Crossroads 38RL. We have been in it since October 2023 and has not been moved. The last few days we've noticed a constant drip of water out the blue hose under the passthrough area on drivers side of RV. Not the hose with the shut off. Can someone please tell me what this is and if I need to worry about it? Thanks

I would guess that is your fresh water holding tank overflow. Chances are your 12 volt pump check valve is leaking back into the tank. You should have a hand valve at the pump between the tank and the pump you can shut off or you could open the tank drain and not worry about it until it get much worse. Try running the pump for a few seconds (with the city water turned off ) and see if you can flush it out .

Thank You, I did as you said and pumped some of the water out. As predicted no more dripping. I will check to see if there is water in tank in a few days.

We had to put a shutoff on that line because when traveling it would drain the fresh water tank.
