Loud explosion while backwashing black tank
Today I was doing my regular duty of emptying/backwashing the black water tank. I had emptied both the grey and black tanks and was in the process of backwashing the black tank. Now I know it says not...

Been there, done that also. In my case I was talking to the neighbor when the big boom happened. :o Tank split front to back. I also had a sprayer hose pop off, but that was more like a pop than a boom. Hope yours was a sprayer, but it most likely was a split. :(
Throw away any fiberglass insulation that got wet as it's compromised. You can but some new pink stuff at Home Depot pretty cheaply for when the time comes.
As far as building pressure I'm not sure what causes that. But I do know based on the inspection I made during dis-assembly that the vent was not dropped into the tank and it was not plugged. I have always wondered if the noise was actually the sound of the tank splitting open under just the weight of the water in it. But then again I could swear that the trailer jumped a bit when the boom happened so who knows.
