Works well but rod was slightly too long

The button mechanism itself is excellent. I had to cut the actuator rod down significantly for my shallow tank, which required a hacksaw. Would be nice if it came in pre-cut sizes.

Solid construction

Feels much heavier and more premium than the original plastic button that came with my toilet. The click action is satisfying and responsive. Deducting one star only because the gasket was a bit tight to seat.

Saved me from buying a new toilet

The plumber quoted me $200 to replace the whole tank lid assembly. This $20 part did the exact same job. Very happy with the durability so far after three months of use.

Perfect replacement for my old broken button

My original flush button snapped off, and this universal kit was a lifesaver. The adjustable rod made it easy to fit my specific tank depth. Installation took about 15 minutes with basic tools.

Good quality but instructions could be clearer

The chrome finish looks great and feels sturdy. However, the diagram in the manual was a bit vague regarding the locking nut placement. Once I figured it out, it works perfectly.

Sleek design upgrade

I bought this not just to replace a broken part but to upgrade the look of my guest bathroom. The matte black option is stunning and matches my new faucet perfectly.

5 FAQ

Q: What tools do I need for installation?

A: You typically only need an adjustable wrench or a pair of pliers to tighten the mounting nut. If your existing rod is metal and needs shortening, a hacksaw might be required.

Q: Can I install this without turning off the water supply?

A: While it is technically possible since you are only replacing the top button assembly, we strongly recommend turning off the water and flushing the tank to empty it before starting installation to prevent water spillage.

Q: Does the chrome finish resist tarnishing in high humidity?

A: Yes, the button features a high-quality electroplated chrome finish with a protective clear coat specifically treated to resist tarnishing and corrosion in humid bathroom environments.

Q: Is the actuator rod compatible with dual-flush systems?

A: This specific model is designed for single-flush mechanisms. For dual-flush toilets, please check our 'Dual-Action Universal Kit' listed in the related products section.

Q: Will this fit a toilet tank with a 35mm hole?

A: Yes, this universal actuator is designed to accommodate holes ranging from 25mm to 40mm in diameter, so a 35mm hole will fit perfectly.
