Low Tech ......Toilet/Tank Issue

I'm not sure this is the right forum but...
Have a new to us 5ver. All our previous experience was with a small class b with a 6 gallon black tank and lots of driving.
The fifth wheel has a 30 gallon black tank. The toilet has a 1 foot drop through two 45 degree bends to get to the shallow end of the tank. With the toilet valve open I can just see a small crescent into the tank.
Twice now, when camping in one spot for a week or so, the toilet pipe has plugged. I do not believe the tank is full, I believe it's just a result of too much poo, not enough water and not enough movement to slosh stuff around....a poo pyramid if you will.
I assume the solution is to just flush more water down with the solids.
The complication is; we are hyper resource conservative(water/power/propane etc.)/off grid campers and want to maximize our time between dumps.
Is there some Magic Poo Grease? (Great product name huh?:B ) or a process we are missing? Or a poo liquefier in a bottle? (Us being hyper resource conservative also means we're cheap so we probably aren't putting as much chemical in the tank as we should.)
I really don't want to have to use a stick to unplug it again as the s#!^^y end has to come back through the camper!
I would appreciate your thoughts and wisdom....no matter how s#!^^y they may be.

    Best thing is to use more water... But, if you really want to conserve water and are "off grid", don't use the black tank! Use the campground facilities, outhouse (if available), or woods if boondocking.
  • My thought is to blast that pyramid and get it over with.

    I have a flexible wand with an attachment on the bottom the twirls. When necessary that takes care of my poo pyramids. Got it at Wally World.
  • MORE WATER!!!

    We keep an ice cooler in the 5er, and pour all the water from the cooler into the black tank.

    We're pretty carefull off-grid, but with a 40 gal black tank we can go 10 days like this without trouble (that's as long as we have tried). I don't know how long you're planning to be off-grid, but 30 gal black is a lot.

  • The best solution would probably be to coat the two elbows that connect to the tank. I use a liquid wax product for that purpose but I would bet that furniture polish or any other product that makes plastic slippery would work.
  • they do make a enzyme that RV dealers sell. it costs about $12 a bottle down here. don't ask me the name of it. It won't do you any good at my age. I used it in Yuma when I forgot to close the black tank valve. it ate up a lot of stuff before I was able to empty again.
