I hear you on the universal kits. They’re like those “one size fits all” hats—sure, they technically fit, but you end up looking ridiculous and your head still gets wet. I’ve seen more than a few Frankenstein toilets where someone tried to save a buck with a generic part, only to call me later when the half flush stops working or the tank starts singing at 2am.
Honestly, chasing down the right part can be a pain, but it’s usually worth it. Manufacturers love making things just different enough that you have to buy their stuff—keeps us all on our toes (and them in business). I’ve tried the zip tie trick too... let’s just say my socks were not happy about it.
If your half flush is acting up, nine times out of ten it’s either a mismatched part or something’s not sealing right. Sometimes it’s just a tiny washer that’s off by a millimeter. Funny how something so small can cause such a headache.

Ain’t that the truth. I’ve spent way too much time chasing leaks just to find out it was a gasket not sitting quite right. I get the appeal of universal kits, but honestly, they’re more trouble than they’re worth in the long run. I tried swapping in a “universal” flush valve on my old Caroma and the half flush just never worked right—ended up with double the water bill that month. Sometimes it’s just worth biting the bullet and hunting down the OEM part, even if it means waiting a week for shipping.

I get where you’re coming from, but I’ve actually had decent luck with universal kits—at least with newer toilets. Sometimes it’s just a matter of tweaking the float or adjusting the chain length. Have you tried fiddling with the settings before giving up on the universal parts? It’s a bit of trial and error, but I’ve managed to get a pretty solid half flush after a few adjustments. Not saying OEM isn’t better, but sometimes the “universal” label just means you need to tinker a bit more.
Honestly, I’ve run into this exact headache with older Caromas. Universal kits are kind of a gamble—sometimes they’re close enough, but those dual-flush mechanisms can be weirdly picky about the geometry inside the tank. The half flush especially seems to depend on the original valve design and how the water drops. I remember spending way too long trying to get a “universal” one to work on my aunt’s old toilet, and no matter how much I adjusted the chain or float, it either barely flushed or dumped way too much water.
One thing that helped a bit was making sure the seal at the bottom of the flush valve was sitting perfectly flat. Even a tiny tilt can mess with the timing of the half flush. Also, some of those universal kits have a little dial or slider for adjusting the flush volume—easy to miss if you’re not looking for it. But honestly, with some older models, it just never feels quite right unless you go OEM.
I get why people want to save a few bucks, but after fighting with it for hours, sometimes it’s just not worth the hassle. If you’re seeing your water bill spike, that’s a sign something’s definitely off. I’d say if you’ve already tried tweaking everything—chain length, float height, even checking for leaks around the seal—it might be time to bite the bullet and track down the original part. Not fun, but at least you know it’ll work as intended.
Funny thing is, on newer toilets, I’ve had way better luck with universals. Maybe they’re just designed with more standardization in mind now? Either way, I totally get the frustration. Sometimes “universal” just means “universally annoying to install.”
I’m right there with you—tried a “universal” kit on my first place and it was a mess. Half flush either trickled or just acted like a full flush. I thought I was being clever saving money, but honestly, tracking down the OEM part was way less stressful in the end. Sometimes it’s just not worth the hassle trying to make something fit when it clearly wasn’t designed for it.
