It started to come into the living area. Waited almost another hour b/f trying to flush it out again- no problems that time.
I did flushed it the day b/f b/c toilet was blocked. We unplugged it and I washed out the black tank no problem.
Any help/advice appreciated… not sure what I did -
ALSO- I looked at the underbelly where it was pouring out of and push it a little and water came out. Now I’m worried about my undercarriage.
I'm assuming from your description that you had the black flush hooked up, and filling the black tank up.
The rule of thumb that I use is this: when it's EMPTY or not much in it, like after a weekend of camping, I ONLY run the black flush for 5 minutes. Then, I drain, and I run it for 5-7 minutes. We're fortunate that our indicators still work on our black tank, and I stop filling when it gets to full or 5 minutes whichever comes first.
As for spilling out, as long as you can get your floor pretty dried out, I wouldn't be too concerned about, but I'm also assuming that you didn't have a lot of nasty sewer water that came out either.
For what it's worth, I understand what you were dealing with, with the clog. For whatever reason, our Pinnacle has done that one us twice, and we've never had another RV ever do that to us, and before anyone asks, YES, we do run a lot of water down there, and do NOT have a poop dome. We've gotten lucky both times that it was plugged, because I filled the black tank up with the wash, and then it had enough force to adequately drain.
Good luck getting yours all sorted out...
