Water lines on 97 Aerbus by Rexhall

We are having a problem with our water lines leaking under the floor of our Aerbus XL 3100. Does anyone know where we can get a diagram of the water line system or tell use how to get to them. It's not leaking under the motorhome, just coming up through the floor. Thanks

  • You’re not gonna find “plumbing plans” or any other for most any RV. And it’s old. Like asking if someone randomly knows where the plumbing lines are in a random home. There are clues but no roadmap for those who don’t know where to start. 
    With that, your RV system does not defy gravity and water doesn’t flow uphill, therefore something in your description of the problem is inexplicable. 
    Water coming up through the floor like an artesian spring AND not leaking down is not something that makes any sense. 


  • Sorry to say this but there is a very good chance nobody has a water system for your unit as very few manufacturers publish or even have diagrams for their systems. Any systems. As in any hobby, your skills or the lack of them will determine how this proceeds.
