I hear you on the frustration—half flushes can be finicky, especially in older setups. I’ve lost count of how many times I’ve been called out for “phantom flushes” or weak half flushes that just leave stuff behind. Sometimes it’s a design flaw, sometimes it’s mineral buildup in the rim jets or the siphon. Ever tried cleaning out those little rim holes under the bowl? It’s gross, but I’ve seen a surprising difference after scraping out the scale. Curious if anyone’s had luck with that, or is it mostly just a temporary fix before things clog up again?
Honestly, I’ve had mixed results with cleaning out those rim jets. Sometimes it helps for a while, but if the buildup’s bad enough, it just comes back in a few months. I usually use a bent wire or even an old toothbrush to get in there—gross job, but it does make a difference. Have you ever checked the float or the fill valve? Sometimes if the tank isn’t filling up enough for the half flush, it just doesn’t have the oomph to clear the bowl. Wondering if that could be part of what’s going on for you.

I’ve totally been there—scrubbing those rim jets is like a weird rite of passage. But yeah, I found out my fill valve was set too low once, so my “eco” flush was basically just a sad trickle. Tweaked it up a bit and suddenly things actually cleared. Not glamorous, but hey, less water wasted and no double-flushing.
Funny, I had a similar issue last year. I kept fiddling with the button and even swapped out the flapper, but it turned out the float was sticking just a bit—barely noticeable unless you really watched it. Once I cleaned that up and made sure the fill valve was set right, the half flush actually started working like it should.
One thing I always wonder about is whether messing with those adjustments too much can cause leaks or wear things out faster. I’m always a bit cautious, maybe overly so, but I’d rather not end up with a slow leak under the tank. Anyone else ever worry about that? Sometimes I feel like these “eco” toilets are more finicky than they’re worth, but maybe that’s just me being paranoid...
I get what you mean about being cautious—sometimes it feels like if you breathe on those adjustment screws the wrong way, something else starts acting up. In my experience, as long as you’re not cranking things super tight or forcing parts, you’re probably fine. I’ve had more trouble with cheap replacement parts than with the actual adjustments themselves. The “eco” models do seem a bit more sensitive, but I guess that’s the tradeoff for saving water (and a few bucks on the bill). Still, I’d rather tweak a float than deal with a mystery leak under the floorboards...
