The original bathroom by the office was running this morning. Not sure how long it had been in that state. A couple of jiggles and pulls and I was able to get it to stop. I left the lid off the back as a warning. Hopefully someone with more skills than I have can fix it.

That… is not the flapper I was expecting. You’re going to need an air force tech for that one.

Yea, it’s been that way for quite some time … though it has been doing much better recently. It used to get stuck on every time it was flushed. We really just need to completely replace the guts.

What is it that gets stuck? On the flapper style the chain often gets tangled but I can’t tell what might be the cause on this style
Ughh. That’s an overly complicated setup that uses uncommon parts. It looks like the flush handle works a cable instead of a chain. And that the flush valve, instead of a flapper has multiple adjustments and rides up and down a tube.
Gutting and starting with conventional components is the recommendation I would give.
A complete conventional kit probably costs less than any one if the three main parts for this setup, and would certainly be less maintenance over time.
Unless one of our members is familiar with this setup it’s not worth messing around with, and should be just downgraded.

Try hacking into the mainframe. 
wow thats extravagant.

This is one of the toilets that you lift the handle for one use or push the handle down for the other use. It limited the amount of water used if there wasn’t much to flush. Originally there was a note on the tank cover.

I’m generally all for innovative things like that but since there’s no onsite maintenance and this is something that could potentially go unnoticed for days, I would support replacement with more reliable and easy to fix hardware.

A better way would be a smaller flush handle within the main handle with its own chain, it would operate a smaller valve right through the top of the large valve.
Large handle would open the main valve.
Small opens the small valve.
Each is set like normal with the chain links.
Water is conserved on all modern toilets! 
Not when I eat Taco Bell
With a normal flapper, that would only make the toilet flush slower. The flapper doesn’t close until there’s insufficient water in the tank to keep it afloat. I’m not sure how the internals work on the installed system but it sounds like that wouldn’t work here either. Again it limits the amount of water that’s allowed to go through by time, but flow rate.

You would need a tube on the small flapper so that its higher up in the cistern. So when the #1 chain is pulled, the water level only goes down to the top of the tube, if the #2 chain is pulled then all the water is drained.
Then we have a chain that says #3 and just gives Oh quotes from Home.

I think your tube theory would work. I considered that but thought it would save on materials to have the built in double flapper scenario. I also thought the chain setting limited how high the flapper goes when flushed and therefore how quickly it dropped… because I’m dumb.
That makes sense. So who’s ready to make a gazillion dollars and save all the water!

The handle works itself loose then the box on the back of the handle comes loose from the base and it stops engaging the cable correctly. I think a silicon / rubber washer was left out of the install to allow the handle to snug up and not work its way loose.
I have the same unit at home and once adjusted it works well. I also have a spare unopened unit if we need replacement parts.
