Yeah, I’ve noticed the same thing with those kits. The flush just isn’t strong enough on some older toilets, no matter how much you tweak the float or swap out the flapper. Sometimes you can get a bit more power by making sure the chain isn’t too slack, but honestly, if the bowl wasn’t designed for dual flush, it’s usually a losing battle. I’ve even seen people over-tighten things and end up with leaks. Just gotta be careful not to force it—sometimes it’s safer to stick with the original setup.
Yeah, I totally get where you’re coming from. Those retrofit kits just don’t play nice with older bowls. I’ve tried dialing in every adjustment, but sometimes the design just isn’t meant for it. Honestly, you’re not missing anything—sometimes it’s just not worth the hassle.

That’s been my experience too, but I’ll admit I keep trying to make it work because I’m stubborn and, well, cheap. I bought one of those universal dual-flush kits thinking I’d save a few bucks on water, but my old toilet just wasn’t having it. Half flush would barely move anything, so I’d end up flushing twice anyway. Kind of defeats the purpose, right?
I even tried swapping out the flapper and fiddling with the chain length, but it was like trying to teach an old dog new tricks. At some point, I started wondering if I was spending more time and money on “fixes” than I’d ever save on my water bill. Sometimes the old stuff just wants to do its thing and be left alone. If it ain’t broke (or at least not flooding the bathroom), maybe it’s fine to let it be.
Honestly, I’ve seen this play out a hundred times—those universal dual-flush kits are a gamble, especially on older toilets. The half flush just doesn’t have the oomph if the bowl wasn’t designed for it. I once spent an afternoon wrestling with one, adjusting everything from the float to the chain, and in the end, it still needed two flushes for anything more than a tissue. Sometimes you’re better off letting the old tank do its thing and saving your energy for something less... splashy.
Yeah, I hear you. Tried those kits on a few of my rentals—once on a ‘90s Kohler and it was a nightmare. Even after tweaking the float and fiddling with the seal, half flush just didn’t cut it unless you’re flushing a spider or something. Honestly, unless the toilet was made for dual flush, you’re probably better off sticking to the original setup. Sometimes “universal” just means “fits nothing perfectly,” you know?
