One of the Hinckley ACA rally attendees had an unpleasant problem when the Black ABS pipe in the wall between the kitchen and bath broke dumping all the sink water onto the floor.
It seems on his coach WRV mounted an electrical box on the floor and when the kitchen slide was extended the flexible drain hose caught on the box pulling sufficiently to break the ABS in the wall.
After several attemps by a number of fellow Alpiners P.P. successfully made the repair.
To see if you could have a similar problem pull the two drawers out of the end of the kitchen cabinets across from the refrigerator. You should be able to see the flexible drain hose on the floor. Inspect to see if there are any obstructions that the hose can get hung up on.
If you have the electical junction box located there fashion a shield from plastic, vinyl flooring or a flexible piece of metal or wood and attach it to the floor with screws in front of and behind the box so that the hose slides smoothly up and over the electrical box.
