1st year living n our RV. the campground owner said leave your blackwater tank open. NEVER NEVER do this!!!!! The tank clogged and it filled up to throat on the toilet. Now as you can imagine this creates an issue.
The trailer was underpinned with a 24 x 36 inch access box off the side for water and sewer connections with a lid and that was my starting point. Snake in hand I entered and removed the 3 inch sewer connector and started the snake up the line... my thoughts right then were hmmmm 50 gallons sewage 1 outlet a valve a small box...
I looked like Robin Williams in the movie RV lol. About 5 years later after remodels and living in this RV last summer I found a clean-out on the line that would of saved me from as said in the movie and as said by my wife "Ur not the one covered in fecal matter" lol. ALWAYS keep tanks closed and add water my 1st lesson in RV life.
