2-Inch Dual Flush Valve Replacement Kit – Fix Leaks & Wobbles, Fits Most 2-Piece Toilets (Glacier Bay, Kohler, Toto, American Standard)

About This Product

If your toilet is running constantly, flushing weak, or wobbling like crazy, you don't need a whole new toilet—you just need this dual flush valve replacement kit.
It's designed for most 2-inch two-piece toilets (not one-piece models), and it's compatible with big names like Glacier Bay, Toto, Kohler, American Standard, and Aquasource.

Just check your flush valve opening (2.
4 to 2.
8 inches) and button hole (1.
9 to 2.
2 inches) before ordering.

This kit gives you both full-flush and half-flush options.

Full flush blasts away solids with no issues, and half-flush uses way less water for liquids—good for your water bill and the environment.
You can even adjust the water level to fine-tune performance.

It's a smart upgrade that restores factory-level power without calling a plumber.

The kit includes everything: flush valve, push button, mounting bolts, and a thick rubber tank-to-bowl gasket.

All the parts are high-quality ABS plastic that resists corrosion and wear.
The extra-thick seal stops leaks for good, and the reinforced design handles varying water pressure without cracking.

Installation is flexible—you can adjust the push-button rod length and overflow pipe height to match your tank.

Trim the button stem if needed, leaving about 1mm clearance for smooth operation.

Everything is water-tested before shipping, so slight moisture on parts is normal.
This is a straightforward, durable fix that'll make your toilet flush like new again.
