Couldn’t agree more about the float height—people underestimate how much half an inch can matter with these things. I’ve had a few jobs where the “eco” flush was basically just a decorative button until we tweaked the water level. Funny you mention the drop-valve style; I’ve seen those outlast the fancier designs by years, and they’re way less finicky if you get hard water. The food coloring trick is a classic—saved me from chasing phantom leaks more than once. Honestly, sounds like you’ve got a good handle on it. These setups are never perfect, but you’re definitely not missing anything obvious.
Honestly, the number of times I’ve seen “eco” flushes that barely move a tissue is wild. Half an inch on the float and suddenly it’s Niagara Falls—go figure. I’m with you on the drop-valve style; less to go wrong, especially if your water’s got more minerals than a geology lab. Ever mess with those dual-flush setups where the cable stretches out and never resets right? Drives me nuts. Curious if anyone’s actually found a brand that gets the half flush right without constant fiddling...

I hear you, but I’ve had surprisingly good luck with the Geberit in-wall setups. The cable’s pretty beefy and, as long as you don’t yank it like you’re starting a lawnmower, it seems to reset every time. For half flush, I actually found tweaking the flush volume (there’s a little dial inside the tank) made a bigger difference than the float height. Maybe worth a shot if you haven’t already? Mineral buildup is still a pain, though—no escaping that if your water’s hard.

That dial’s a lifesaver, honestly. I used to mess with the float forever and barely noticed a change. Still, I swear some brands just never get it right—no matter how much you tweak. Maybe it’s just me, but I feel like the cheaper setups are always finicky.

Funny thing, I've actually had more trouble with the “premium” models. Sometimes all those extra features just mean more stuff to go wrong. Honestly, if the half flush isn’t working right, I’d double-check the flapper or seal too. Sometimes a tiny bit of buildup messes with the whole mechanism—no amount of dial-turning will fix that until you give it a clean.
