We have two bathrooms in our rig, so also two black and two grey water tanks. Today was move out day. I was inside packing up, and Jason was handling the outside. We had put a Y connector on our tanks, and he had pretty much emptied everything and was just flushing them out. He was walking by (not even touching it!) and it exploded! Ok so maybe it didn’t explode but it broke and sprayed all over Jason. Let’s just say “sh*t got real”. I mean, I guess it could have been worse...it could’ve been me.
