Water...please tell me it's gonna be ok!

We had a mishap in our new to us 2013 tt. I haven't even slept in it yet:( we are letting my parents stay in it during a visit this weekend. Someone turned on the shower when the water was off and left the valve open. Then someone locked the door and turned the water on outside. I was standing outside a few hours later and was wondering what that dripping noise was. It was coming from the underbelly. The shower filled up and water was running down the floor to the front left side of the trailer. Fortunately, I had the trailer pitched down and to the left. I vacuumed all of the water and punched a hole in the underbelly to let it drain. I will run a dehumidifier tomorrow all day and keep the windows open and roof vent open as much as possible for the next week. Anything else I can do? Will the underbelly dry up or will I have a mold problem?

I think I am going to be sick now! : ( my parents feel terrible about the mess.

    I agree with this, too. We've had a "flood" and once it was dried up, it didn't get moldy. IF your underbelly has insulation, you may want to see if you can get to it to dry it out.

    PS -- reminds me of when my folks borrowed my old MH. Brought it home after 2 days and told me there was a "stink" in the holding tanks....they'd poured 3 gallons of chemicals in it but the stink was still there. ???? I'd cleaned it out...couldn't figure it out. I asked if it was possibly LP they were smelling. My step dad informed me that LP doesn't have a smell (yeah, right --- I know -- he was wrong). SO, since he delivered it to my house, I waited till I got off work and opened the door. OMG.....they'd left 2 burners ON and not LIT, the smell of propane dang near knocked me on my a$$. I reached under the rig and turned it off. They had NO idea they'd turned on the burners without lighting the burner!!!!!!! (and yes, I HAD told them it didn't have an electronic ignition). They had driven it 250 miles to bring it home!!!!!!! That was the last time I let anyone use my rig.......:)
  • Although it's kind of a pain I would pull the underbelly and take a look. Or at least pull the corner where it was dripping out and see how wet it is. You might get lucky and only have to replace a corner of the insulation.

    Honestly though a roll of insulation from Home Depot is $13. You could pull the underbelly, let it dry for a week and then put new insulation in and put the screws back in. It really isn't that big of a job once you get started.

  • Water fitting blew off on backside of our water heater while we were sleeping.......water ran for hours, flooded kitchen/living room area, down into basement storage compartment and into underbelly

    For the underbelly.....I unscrewed the rear portion across back of 5th wheel and the front portion across the front of 5th wheel......stuck 2 fans in rear and let them blow for 2 days then sealed it back up. NO issues.

    Insulation in our underbelly is foil/bubble/foil....doesn't absorb water

    Good luck!
  • You will likely have to remove the underbelly covering and all the insulation as it is probably soaked and mold will be growing in that. Plus the underside of the floor is probably wet also and it will be a real problem later if not dried out asap. Good luck to you sir.
