Connect downpipe to flush mechanism
 

I don't think this is doable but I said I'd ask. Old flush high level mechanism was replaced with new one, and the new one is crap in comparison, it keeps sticking & I've not found any reason why, it's A1 ok when out of the cistern. He wants the old one back if possible.

The old one the fixing nut was jammed on, had to angle grind it off, so there are 2 problems.
1. The projecting threaded brass is too short - thre's a lot of thread but the plastic cistern is very deep at that point. So I doubt it's fixinnable
2. I don't see how to connect the downpipe to it
Non-problems:
3. the cut off end is rough, but that can be tidied up

Is there some way to connect the downpipe?

Would something like this work?

Connect it to the brass inside the cistern and then thread it through the hole and connect downpipe to it. Not sure how your setup seals the hole in the cistern but that would have to be done here too obviously.

I did a quick Google for Plumbing thread extenders which came up with a few variations on this.

If there is a few mm of brass thread showing you could use a female BSP
to solvent weld adapter, easily available, to double as connection and
backnut. If there is no thread showing, is the cistern thick part wide
enough to counterbore it at about 3" diameter? Not sure how, a
router??
