Yikes! I was just telling a friend a few days ago, "Everyone has a black Tank story or something that went haywire...".
We have another one although thankfully it turned out a lot better than it might of. Last post I mentioned a unique thing about our current campground at Ocean Pines - it was formerly a Mobile Home park that was converted to an RV campground.
And -- the sewer connections for each site are positioned directly between where the two rear wheels are on the RV. That puts them in the middle of the camping spot instead of off to one side near the water and electrical.
That normally would not be an issue. It was a little inconvenient laying flat and crawling under the motorhome to hook up the sewer. But that's what I did. Made the connection fine. In fact I did that before Pam put down the jack's so I had a little more room to get under there.
I even propped up the hose along the way to make sure it was draining downhill. It was working well. I was feeling good about this. Thinking of everything and such...
Two days later I decided to empty the tanks and I started with the black tank. It seemed to be draining and then stopped. Hmmm. You can see where this is heading...
I looked under the wet bay followed the sewer hose back. Hmm. I found the problem. It seems that I made sure the hose avoided the tires and went around them. But it was directly under the DS rear jack.
Oh boy! This could get exciting. The black hose was now completely fuel up to the point where it was squished. If I removed the hose in the wet bay connection I could drain that part of the hose but really had no where to drain it.
For this effort I needed my boots, plastic tarp to lay on the puddles, and wet ground and the pads for the jacks so I could easily tell where not to reposition the hose. Then we had to pull in the slides and raise the jacks.
