I get where you’re coming from, but I’ve actually had better luck with some of the newer dual-flush models. The trick seems to be regular cleaning—especially if you’ve got hard water. If you let the buildup go, yeah, they get fussy fast. But with a bit of maintenance, I’ve seen them last years without much hassle. The old tanks were solid, sure, but I don’t miss the water bills from those days...
I see your point about maintenance making a difference, especially with hard water. Still, I’m not totally convinced that regular cleaning is the whole answer. You mentioned:

That’s fair, but in my experience, even with consistent upkeep, some dual-flush models just don’t deliver enough force on the half flush. I’ve tried a couple of brands (can’t remember the exact models, but both were less than five years old), and it always seemed like the half flush was more symbolic than functional. Maybe it’s the design or maybe it’s just my luck, but I’ve ended up double-flushing more often than not—which kind of defeats the purpose.
I do agree about the old tanks being water hogs, though. My water bill dropped noticeably after switching. But I wonder if there’s a sweet spot between efficiency and reliability that manufacturers haven’t quite nailed yet. Some of these newer toilets seem to prioritize saving water over actually clearing the bowl, which can get frustrating.
Curious if anyone’s found a model where the half flush actually works as advertised without needing constant tweaks or deep cleans. Or maybe it’s just a matter of adjusting expectations? Either way, I’m still on the fence about whether the trade-off is worth it.
Honestly, I get where you’re coming from. I’ve tinkered with a few dual-flush setups, and even after swapping out all the seals and making sure the mechanics were spotless, the half flush just felt… underwhelming. Like, it’s technically doing something, but not always enough. I do appreciate the lower water bill, but yeah, sometimes it feels like you’re trading one hassle for another. Maybe there’s a magic brand out there, but I haven’t stumbled across it yet. Hang in there—sounds like you’re not alone in this weird half-flush limbo.

I get what you mean, but I’ve actually had the opposite experience with a couple of dual-flush setups—specifically the Toto Aquia. Maybe it’s just luck or my water pressure, but the half flush on mine handles most jobs just fine. Not saying it’s perfect, but I haven’t run into the “two flush minimum” problem as much as folks seem to online.
That said, I do think a lot of these systems are way too finicky. If the tank isn’t filling up quite right, or if the float’s even a little off, the half flush basically turns into a glorified drizzle. And yeah, some brands are just... not up to snuff. But I wouldn’t write off all dual-flush toilets as being stuck in “half-flush limbo.” Maybe there’s more to it than just the seals and mechanics—sometimes it’s just a mismatch between the setup and your plumbing.
Funny thing is, I’ve seen more issues in newer builds than old houses. Go figure.

Man, that hits home. I had this “eco-friendly” dual-flush thing installed during my bathroom reno last year—brand swore it’d save me money and water. Half flush is supposed to be for “liquids only,” but in practice? It’s like a polite suggestion. Sometimes it works, sometimes... well, let’s just say I keep the plunger within arm’s reach.
I figured maybe I got a dud or messed something up on install (wouldn’t be the first time). Ended up fiddling with the float and adjusting the chain length more times than I’d care to admit. At one point, it was flushing so weakly I thought maybe a hamster could clog it.
What’s wild is my neighbor across the street has some ancient tank from the ‘80s—single lever, no frills—and that thing could probably flush a potato without breaking a sweat. Meanwhile, my fancy new toilet is out here struggling with tissue paper.
I do think water pressure makes a difference though. My place is at the end of the line on our street, so sometimes it feels like we’re running on gravity alone. Maybe that’s why these newer systems are hit-or-miss in newer houses? Or maybe there’s just too many variables for one-size-fits-all hardware.
Anyway, I haven’t written off dual-flush totally yet (I mean, when it works it really does save water), but yeah... definitely not as foolproof as they make it sound in those glossy brochures. Sometimes you just want your throne to do its job without all the drama.
