2018 2106 fbs sewer leak
From North East Texas
Just bought a slightly used 2018 model 2106 fbs and took it to Lake Dequeen,Ark this last week and had a problem with the black water tank.
Before I took it up I accidentally connected my water hose at home to the black tank flush connection and turned on the water. It hadn;t run long before water started to come out from under the undercover around the drain pipe. I turned the hose off and the water quit coming out,so I thought no harm.
Jump to last week at the campground and after three days of little comode use the sewer started coming out from under the undercover in the same place the water came out earlier, it was smelly sewer water, There was not water backed up into the comode and the tank gauge showed half full.
I've looked for plumbing diagram but not luck. Has anyone had this happen and what possible cure or fix is there?
I would appreciate any and all responses.
