Black tank flush pouring water on to ground beneath RV.

[HVrunner]

I tried my black tank flush the other day for the first time. Water poured out on to the ground under my 2015 24R MBS. I thought I would take a quick look underneath to see what might be the problem. After reading several posts on this forum I had an idea of what to look for before taking it in to be repaired under warranty. The lines were either never connected or it froze during the winter it sat on the dealership lot and broke the clamp or burst the tubing. Not sure which.

I will add a new length of tubing and two clamps and save a five hour round trip to the dealership for warranty repair.

It's hard to tell, but sure looks like they were never connected.

The fitting looks dirty like there was never a line connected to it,

There was some black sealant in the end of the blue PEX tube coming from the exterior hose fitting. It was probably never connected.
