Ok, so here's what I did and what I found:
I left work for two hours.
Got home and checked the floor. It was only wet in the bathroom. The carpet was soaked in a couple areas.
I turned on the hose to the RV again and immedietly water came down outside in the back left corner. It comes down in two spots .. near the bathroom and at the very back by the bumper. The RV is at an incline in our driveway so I assume that makes sense since it would ride the frame back.
I went inside and felt the back of the toilet where the metal pipe goes down through the floorboard, and it was wet and had slight drops, but NOTHING to the point where it would create the steady stream of water going outside. So, although I have something I need to tighten down/seal there, the cause doesn't seem to be at that pipe.
I opened up the small panel on the outside of the RV by the toilet where the electrical hookup is, and noticed the floor was wet where the cords and hoses rest. However, the ceiling above it was dry. It goes back to the left (towards the front of the vehicle) so I assume that since its on an angle the water must be coming farther from the left and going down the incline. In that same compartment is the water hookup on the outside.
I stopped troubleshooting from there, turned off the water, and ran to Home Depot. I rented a dehumidifier for $40 for the next 24 hours and set it up in the bathroom in the RV. I then turned on the heater in the RV as well and closed all the doors to the outside. Then I drove back to work.
When I get home tonight, I hope it'll be dry.
My next step will be to troubleshoot, but I don't know RVs so I don't know what all I should look at.
My thoughts at the moment are:
- Check where the hose connects to the RV, and make sure the fittings on the opposite side are tight.
- Aim a flashlight in the electrical compartment on the outside and if I turn on the hose, see if water is gushing out from somewhere.
The thing is, I would think the issue would be from above (toilet) and not below because if it was below the wood and the carpet in the bathroom shouldn't be wet. Right?
Anything else I should look for in the toilet? Do the toilets have any water hookups inside the plastic, not just at the pipe in the back?
Thanks!
