Half flush never seems to work right - am I missing something?

Holding the lever down a bit longer is pretty much the exact hack I used. Not fancy, but hey, if it works, it works...

Funny enough, I’ve run into this in a few rentals. Sometimes those dual-flush systems just aren’t matched well with the old pipes or the bowl shape - like you said, more of a “quarter flush.” Had one tenant who swore by just using the full flush every time, efficiency be damned. Honestly, unless you’re on brand new plumbing, half flushes rarely do the trick.

Yeah, I’ve noticed the same thing - half flush just doesn’t cut it in my place either. I tried adjusting the float and even swapped out the flapper, but still ended up double flushing half the time. Kind of defeats the purpose, right? I guess unless you’ve got newer plumbing, it’s just not worth the hassle.

That’s exactly what I keep running into. I mean, I love the idea of saving water - my inner tree-hugger is all about it - but when you have to flush twice, it’s like the universe is mocking your eco-friendly intentions. I’ve got one of those “dual flush” toilets that’s supposed to be all high-tech and efficient, but honestly, the half flush is more like a polite suggestion than an actual flush. It’s like, “Hey, maybe this will work... or maybe you’ll just have to try again.”

I even tried the old “if it’s yellow, let it mellow” routine for a while, but my partner was not amused. Apparently, there’s a fine line between saving water and grossing out your housemates.

I’m curious - has anyone actually had luck with these things in an older house? My plumbing is from the 70s (and not in a cool retro way), so maybe that’s part of the problem. Or is it just that some toilets are better at pretending to be eco-friendly than actually being eco-friendly? I keep hearing about people who swear by their dual flush setups, but I’m starting to think they must have magic pipes or something.

Anyone ever try one of those retrofit kits that claim to make any toilet “dual flush”? I’ve been tempted, but I’m skeptical after my last attempt ended with a minor bathroom flood and a very soggy bath mat.

I tried one of those retrofit dual flush kits a couple years back, thinking it’d be a quick win for water savings. Ended up with a leaky tank and a handle that felt like it was about to snap off every time I used it. My house is from the late 60s, so maybe the old plumbing just isn’t made for these “modern” upgrades. Honestly, I think some toilets just aren’t built for half flushes - no matter how much you tweak the float or swap out parts, they just don’t have the right design. The only person I know who’s happy with theirs has a newer toilet that was made for dual flush from the start... Maybe that’s the trick?

Honestly, I’ve wondered the same thing. Those retrofit kits always seem like a good idea until you’re fiddling with a wrench at midnight, right? I’ve seen older tanks where the flush just doesn’t have enough “oomph” for a half flush to actually clear anything. Did you notice if the flapper was sealing properly after the install, or was it just constantly trickling? Sometimes the chain length or the angle of the handle makes a difference, but I agree - some of those old tanks just aren’t built for these upgrades. Maybe it’s a case of “if it ain’t broke, don’t fix it”… or at least don’t try to make it fancy.
