I get what you mean, but I’m not convinced it’s always just the cable tension or seal. Sometimes I wonder if the flush valve design itself just isn’t up for the job, especially with older cisterns. Has anyone tried swapping out the whole assembly, not just tweaking the kit?
Swapping the whole flush valve assembly made a big difference for me, actually. The old design just wasn’t sealing right no matter what I did—new seal, cable tweaks, nothing helped. Once I put in a modern dual flush valve, it finally started behaving. Some of those older setups just don’t play nice with newer parts. If you’re already elbow-deep in the cistern, sometimes it’s just easier to start fresh.
That’s a solid move—sometimes those old flush valves just aren’t worth the hassle. I’ve tried swapping seals and fiddling with the linkages too, but it always felt like chasing my tail. Did you notice any difference in water usage with the new dual flush? I’ve read some models don’t actually save much unless you dial them in just right. Either way, getting rid of that constant leak is a win.

Yeah, that’s been my experience too. Some of these dual flush setups are more hype than help if you don’t tweak the settings. Half flush can be pretty weak, especially if the float’s not adjusted right. I’ve seen folks end up double-flushing, which kinda defeats the purpose. Still, anything’s better than a leaky valve constantly running up the water bill.

Yeah, I’ve noticed that too. If the float’s off even a little, the half flush barely does anything and you end up flushing twice. Honestly, I’ve had better luck just making sure all the seals are tight and nothing’s leaking. Dual flush is nice in theory, but unless it’s set up just right, it doesn’t always save much water. Sometimes feels like more hassle than it’s worth.
