Sometimes the disc from cutting out the opening for the 3" pipe can be left in the tank and will plug the outlet. Who knows, since you've had the TT for a few years, maybe "someone" put something into the tank they shouldn't have.

After having an in-tank flusher, I have found that it works much better than a back-flush elbow, but you want to use it to clean your tank (when dumping at the CG) to get the tank clean before you head home. I only use our elbow now to watch what's coming out (and to provide an angled transition).

The solution is prevention. Add 4 or 5 gallons before you use the tank, use lots of water when flushing #2, and fill the tank up before you open the valve. Resist the temptation to skimp on water to extend the time before you need to dump the tank.

You might try getting a stiff, hard-walled garden hose and pushing it up into the tank and down into the tank to try and break up the solids and clear it. A plumbing snake might work in through the outlet.

If all else fails, you can use liquid drano. Our owner's manual actually says to use it if needed and we did use it once. It MUST be the version that does not attack metal and DO NOT ever dump it into an on-site septic disposal system or you can permanently damage it. If you use this, you'd want to tow your TT around a bit to slosh the contents around inside the tank. Your tank will end up clean as a whistle.
>Might need to try this. I have a wand I can stick down in the tank that has a 90 degree pointed outlet spout that I am hoping I can use to break it all up so it will drain.
>I also wonder if the Flush King as suggested in previous posts will even be that effective. The drain pipe goes from the side of the camper to the back side of the black tank, takes a 90 degree turn then hits the valve then goes into the tank. My local RV dealer claims the 90 degree elbow at the entrance to the tank renders the Flush King pretty well useless and he even had on in stock I was prepared to buy until he talked me out of. If all else fails I still might try it.
