Sometimes it really is just about tweaking the setup instead of replacing parts.
That’s true, but I’ve seen a few cases where folks kept fiddling with adjustments and ended up with a slow leak they didn’t notice for weeks. Ever checked if your water level is set too high or low? That can mess with the half flush more than people realize.

Yeah, that’s a big one. I’ve had a few calls where folks swore the dual flush valve was broken, but the real culprit was the float set just a hair too high. Once, I found the chain was actually catching on the overflow tube, which made the half flush act weird—like it’d start, then just dribble out. I always check for those little things before swapping out any parts. Sometimes it’s just a matter of adjusting the float arm by a notch or making sure the seal isn’t gunked up. It’s surprising how much those minor tweaks can throw things off.
Had a tenant once who swore up and down the toilet was haunted because the half flush barely worked. Turned out the flapper was just a bit warped and not sealing right. Funny how something that tiny can cause so much drama... I always double-check the seal and chain before touching anything else. Sometimes it’s just a five-minute fix, but folks expect a full-blown replacement.

Honestly, I get where you’re coming from, but sometimes it’s not just the flapper or chain. I’ve seen dual-flush toilets where the half-flush never worked right because the internal float was set too low from the factory. Adjusting that made a bigger difference than swapping out parts. Not every fix is a five-minute job, unfortunately...
Half Flush Never Seems To Work Right—Am I Missing Something?
I’ve been scratching my head over this too. Our place came with one of those “eco-friendly” dual-flush toilets and honestly, the half flush is pretty much useless. Tried checking the chain, the seal, even swapped out the button mechanism because I figured maybe it was sticking. Nada.
The float thing you mentioned makes sense though. I didn’t even realize you could adjust that until I watched some random YouTube video after getting frustrated enough. I fiddled with it, but it’s so touchy—one notch up and it’s like Niagara Falls, one notch down and nothing happens. There’s no in-between. Not sure if it’s a design flaw or just me being impatient.
Funny thing is, my neighbor has the same brand and his works fine. He swears by “just holding the button down longer,” which sounds a bit like a workaround, not a fix... Maybe these things are just finicky by nature? Or maybe there’s some magic combo of settings I haven’t found yet.
Either way, it’s definitely not always a quick fix. Sometimes I wonder if these water-saving toilets actually save water when you have to flush twice every time.
