Somewhere on here someone just had a catastrophe with sewage being pushed back through their trailers system when they left the gray tank open, and the campground had a major problem. I will leave mine closed till dumping.
Yuck
Exactly ^^^^^^^^^ . Leave it open and you're taking a big risk. I can't fathom the mess and stench if it backed up into a trailer while being away. Honestly it won't kill you to pull the grey valve every other day.
Now if I can just remember to shut the water off when we leave. And yes, I've seen water flowing out of a camper while the owner was gone. I shut it off from the main. It was running like a waterfall out of every possible place near the floor line. I didn't bother the guy to see the damage when he return, the look on his face was enough. I felt sorry for him.
