Honestly, I hear you on the troubleshooting, but I’ve actually had better luck with the newer dual-flush setups than the old levers. Maybe it’s just my house’s water pressure or something? The half flush was super weak at first, but after swapping out the cheapo flapper it came with, things improved a ton. Ever tried one of those aftermarket kits? Sometimes it’s less about the button and more about the guts inside... though yeah, the float adjustment is still a pain.
It’s reassuring to hear someone else has had a better experience with the newer dual-flush setups. I was skeptical at first, especially after reading so many complaints about weak half flushes, but it’s interesting how much difference a simple flapper swap can make. I’ve noticed the stock parts that come with these toilets are often just the bare minimum for function, not really optimized for efficiency or longevity.
Water pressure definitely plays a role, but I’ve found that even in my older house (where pressure isn’t exactly stellar), tinkering with the internal components can go a long way. I tried one of those universal dual-flush conversion kits last year—honestly, installation was a bit fiddly, but once I got the float adjusted just right, it worked better than expected. The trickiest part was getting that balance between water savings and actually clearing the bowl... not always as straightforward as the packaging suggests.
I totally get what you mean about float adjustment being a pain. It’s one of those things where you think you’ve got it set perfectly, then two days later you’re back in there making tiny tweaks because something’s off again. It’s almost like these systems are more sensitive than they need to be.
One thing I’d add—sometimes mineral buildup around the valve or flapper seat can mess with performance too. A little vinegar soak every now and then has helped keep things running smoothly for me. Not sure if that’s common knowledge or just something my dad drilled into me growing up.
Anyway, it sounds like you’re on the right track experimenting with different components rather than sticking with what came in the box. It’s kind of satisfying when you finally get everything dialed in and see your water bill drop a bit... even if it takes a few rounds of trial and error to get there.
Getting the half flush to actually do its job can be a real headache. I’ve run into the same thing—sometimes it feels like you’re just sending a trickle down the bowl and hoping for the best. You nailed it about the float adjustment being finicky. What’s worked for me is making tiny tweaks, then flushing a few times to see if it holds up, instead of just setting it and walking away. Sometimes you think you’ve got it, but then a day later, nope.
One thing I’d add: check the chain length on the flapper or flush valve. If it’s too tight or too loose, you won’t get a good seal or enough lift, which messes with both flushes. Also, if your tank water level is set too low (sometimes to “save water”), it can make the half flush almost useless. I usually bump it up just a bit above the manufacturer’s line—seems to help without wasting much extra water.
And yeah, mineral buildup is sneaky. I’ve seen some tanks where the valve seat was basically crusted over... vinegar soak is a solid tip. Sometimes I’ll even use an old toothbrush to scrub around those parts if things look gunky.
It’s definitely a process of trial and error, but once you get it dialed in, it’s worth the hassle.
Honestly, I’ve been down this road and it drove me nuts for a while. The half flush on ours was basically useless until I realized the button itself wasn’t always engaging the mechanism fully—just a little off-center. I ended up popping the lid off and watching how the parts moved when I pressed each button. After a few tweaks to the chain and a tiny bump to the water line (like you mentioned), it finally started working better. Still, it’s never quite as strong as I’d like, but at least it’s not just swirling around doing nothing. Sometimes these “eco” features feel more like a puzzle than a solution...

That’s exactly what I ran into—half flush just kind of swirling and not really doing much. I’ve always wondered if these dual-flush systems are more about ticking a box than actually saving water, especially when you have to flush twice half the time. You mentioned tweaking the chain and water line, which helped a bit. Did you notice if the flapper itself was sealing properly? I found on mine, the rubber had a tiny warp, so even with adjustments, it never quite worked as intended.
I get the idea behind these “eco” features, but sometimes I question if the design is really optimized for everyday use. Is it just me, or do some of these mechanisms seem overly complicated for what should be a simple function? I’m all for saving water, but not if it means extra hassle or wasted time fiddling with parts. Maybe there’s a sweet spot with older models and a simple displacement device instead...
