I use Calgon and dawn as my tank cleaner/deodorizer and I thought plenty of water. I'm definitely frustrated!
I agree with others - TP is not a problem to worry about. Once you figure out this current dilemma, please feel free to flush TP.
The cutout in the tank is a good possibility. The idea of sending a camera up the outlet line is the BEST ANSWER. Towns and municiapalites regularly send robotic cameras sown the sewer mains to look for breaks, blockages, and illegal connections.
Roto-Rooter plumbers have similar equipment. Heck, most plumbers today will have a drain camera, or be able to rent one from the local rental depot store.
It's just effluent, solids, and waste paper. My 2 year old can fill a diaper up with it, and I deal with it on a daily basis. We all do it. Whatever you send up the line should be hosed off and then sanitized with bleach. No Biggie.
There are only so many places that restrict flow - and the most likely culprit is something bridging across the tank wall where the outlet pipe is molded.
A camera will get you the truth as to what you are dealing with. Then, you can formulate a plan to go after it. Other than that, we are all shooting in the dark so to speak. Sending copious amounts of water up the line may help dislodge it , but if its a floating piece, it may very well block again.
the sewer line is typically conected to the Black Tank at a molded outlet, and the 3" pipe is generally JUST connected with some adhesive goo and a stainless steel pipe clamp. It should not be PVC Welded to the tank. This is so people can do exactly what you're going to do - disconnect the pipe at the Black tank, reach into the tank, and grab the offending blockage.
It would be best if you had a septic pumper truck pump the tank first, of course. But... its just poo.
Folks - this is just one more reason why I have no desire to go "seasonal."
