Now I am literally thinking "oh crap"!!!
After numerous failed attempts my only option was to remove the valve and deal with about 40 gallons of poop!!! I'm not going to describe the mess, it was big!!! When I finally was able to remove the valve I found a disc of plastic completely covering the valve inlet. At the factory when they drilled out the tank openings one of the pieces was left in the tank, it eventually made its way to the valve and stopped all flow.
I cussed Thor for several days after the incident! Luckily I was at my home campground and not on the road, had more stuff available to deal with the mess.
If I had a flush king I might have been able to clear the blockage temporarily but still would of had to deal with the plastic disc at some point. I wouldn't wish this to happen to anyone!!!

Factory drilling of the outlet holes in these tanks and letting the cut-out piece drop back into the tank is very common. That round piece of plastic may lay in the bottom of the tank for years and never cause a problem, or like has been described above you may have an issue with it.
I am not a plumber but common sense tells me that the best way to dislodge something from my gate valve is to blast water from the outside in, forcing whatever is in the gate valve back into the tank. Using a Flush King plus only putting Scott's RV butt wipe in the tank has kept me trouble free with my sewer systems in 3 different RV's, 3 years of which involved full time traveling.
