2005 305BHS New Owner - Leak Near Slideout

[theck4291]

So I just purchased this from a family member, actually I got this, a 1985 CJ5 Jeep with a plow, and an Exmark zero turn mower on a trade for a Kubota tractor, so I honestly came out way ahead. Anyways, I have a leak and I can NOT figure this out.

The leak is on the floor directly in front of the back bench on the slide out. I don't see any issue with the fresh water connection, nor the pipes that come off of that. There is a little sponge-thingy on the exterior of the camper at the bottom rear corner of the slide out that is soaked everytime I go out there. (Mother in law visiting for a few weeks and is the first occupant using it)

It is wicking up the floor and soaking the carpet. I shut off the water but it was still getting wet. I tried shutting off AC and it was still wet(but I didnt realize it rained that night)

So how I have it now is:

Fresh water SHUT OFF
Floor dried up(so I can see if it gets wet again)
AC ON (to see if the leak is caused by AC)
Camper was off level from settling- just releveled it
Hose for fresh water DISCONNECTED from camper, and all lines drained.

What else can I do/try? anyone else happen to have a leak in this location that knows how to fix this?

Has it rained? Old roofing caulk is known to cause leaks. Sometimes the gasket around the slideouts can cause issues too.

To test if it is piping issue. Put water in the FW tank. Turn on the pump. Sit back and relax. If the pump cycles periodically you have a FW plumbing leak.
