Funny, I used to blame the toilet too until I realized the half flush just needs a bit more TLC. Sometimes those little holes under the rim get gunked up with hard water deposits—scraping them out with a wire fixed mine. Float height matters, but honestly, I’ve seen some tanks where even after adjusting, it’s still weak. Guess some designs are just stubborn.
Yeah, those little rim jets are sneaky. I’ve seen folks pour a gallon of vinegar in the tank and let it sit overnight—works wonders on mineral buildup. But honestly, some dual flush models just don’t have enough oomph, no matter what you do. I’ve even swapped out the flush valve on one and still got the same weak half flush. Sometimes it’s just a design that’s more about saving water than actually getting the job done. Kind of annoying, but that’s plumbing for you...
Had the same headache with a couple of units I manage. One trick that helped: I took the tank lid off and watched the half flush in action—turns out, the chain was a hair too loose, so the flapper wasn’t opening fully. Tightened it just a notch, and suddenly the half flush had way more kick. Not saying it’s always the fix, but sometimes it’s just those tiny adjustments that make a difference... though yeah, some models are just underpowered no matter what you do.
Had a similar battle with my dual-flush, and honestly, I started to think it was just mocking me. I’m all about saving water, but if you have to flush twice, kinda defeats the purpose, right? Anyway, here’s what worked for me, step-by-step:
1. Took the lid off (careful, those things are heavier than they look).
2. Watched the half flush like it was a science experiment—turns out, the button wasn’t pushing the mechanism down far enough.
3. Adjusted the little plastic arm inside (mine had a tiny screw to tweak the height).
4. Gave it a test run with some tissue—success, finally.
I do agree, some models just don’t have the oomph, no matter how much you tinker. But sometimes it’s just a matter of fiddling with those weird little parts inside. If only toilets came with a user manual written in plain English... or maybe a YouTube channel for “Toilet Tweaks 101.”

Honestly, I’ve lost count of how many times I’ve had to explain to folks that half-flush issues are usually just a matter of adjustment, not a design flaw. The plastic arms and those tiny screws are the real culprits most of the time. But yeah, some models are just cheap—no amount of fiddling will fix a weak flush if the design’s bad. Manufacturers really need to step up their game with clearer instructions and better build quality.
