Inside Diagram of Black Tank

Hello, wondering if there is a diagram of the inside of the black tank flush system for a Paradigm 390MP. Need to see where the sprayer is at in the tank. Accidentally dropped a handled scoop into the toilet tank when adding the refuse disolver and need to know if it is going to cause any problems with the sprayer. Also need to see the drain pipe diagram to know if it is going to get stuck when trying to flush the system. Please help, thank you.

Did you ever get an answer? I have a similar situation.

Just my $0.02 on this 2 year old thread (LOL) but a small scoop is unlikely to cause a problem — certainly not with the sprayer. The sprayer is likely to be near the top of the tank at the drain end. In the unlikely event that, when dumping, it stopped at the dump valve it would cause the valve to not close but would be eventually be flushed out.

What an interesting/unfortunate problem. I would guess, that eventually it will be a problem. I don't think there is an easy fix to this. However, I would offer this as a possible remedy, before this does become an issue. Most plastics can be cut and then welded back together...like a kayak. All you need is a similar plastic and a heat gun.
--Drop the tank when empty.
--Cut any access you need at the top and remove it. Then weld the piece you cut out, back in place.
--OR you can go for total replacement.
I am interested to hear the other ideas floating around here!

EDIT: I forgot to say that I would try fishing it out first!

We dropped a toilet brush (approx 12” long with looped brush). I believe I need to try and get a scope with a claw to get it out. Just testing the forum to see if anyone has had issues of plugging with similar dilemma
