Water leak under rig

I have a steady dripping from the bottom of the rig under the water bay on the battery side toward the center. I have replaced the main waterline to where it splits behind the hot water tank and have inspected everything I can see. Are there water lines between the bottom of the rig and the basement floor of the water bay? I don't see a leak from the water bay anywhere but the dripping seems to be getting worse. It only leaks when I am plugged into an outside water source.
Thanks

Not sure if your coach has a hose reel or not, but that is a fairly common leaking point. Where hose attaches to reel. I just chased a water leak in my coach for the last month or so, and it was coming off the Oasis hydronic heater. Not sure if you have one of those or not either.... Water leaks hard to pinpoint sometimes unless they are active while looking...good luck.. PS ...water can travel away from leak before it resurfaces... check all your bays for wetness...

It could be the pressure relief valve on the water heater, we had a similar leak experience years ago. Being hooked up to city water the expansion gap in the water heater filled with water and over powered the relief valve.

You need to find it ASAP and then dry out the basement floor sandwich. 

Your rear bulkhead will appreciate your efforts.

I think I'm past that point actually. I bought her as a project but life circumstances changed and I'm currently a full-time and haven't been able to do that work. My investigations have revealed the back part of the basement structure below the water bay is in need of replacement. I got her very cheap so I'm not upset but I don't have a place (or the funds currently) to have it done. I have read the section here on that and am contemplating doing the work myself when I can arrange different living arrangements because I would like to redo the rear bulkhead because the person who had it before me tried a shortcut and it caused the fiberglass to bubble. I see it's a lot of work but I also know I can put about $20g into it and still at least double my money if I decide to sell it after I'm done. My company went under doing Covid so pretty much everything is on hold besides what I absolutely need to do. I won't be taking her up north this year though which is kind of a bummer. Won't be able to do that until the big fix is done I think. I came back to FL from MI in November and I have some structure issues from the last trip...windshield etc...

"Won't be able to do that until the big fix is done I think".

Kenny, sorry to hear. I would definitely not drive that coach any distance with this issue. Best wishes.
