Best With One caveat: Fluidmaster Universal Toilet Kit

Buy on Amazon

Fluidmaster has been making great kit for years, thanks to a combination of clever design and appropriate materials. This toilet kit does not have an overflow pipe. Essentially, this kit eliminates two of the most common malfunctions that cause a toilet to continuously leak water, the flapper and float/valve assembly. It fits 2” flush valve toilets including kohler, toto, and american standard & more. The 400carp kit features a universal design, fitting most 2 flush valve toilets, as well as corrosive. The flow valve is a standard float-based control.

This unit is probably best if you're forced to fix a non-standard drain seat, or a drain seat cracked on top and where the adhesive putty of the FluidMaster makes for an easier repair than dismounting the tank and replacing the whole drain seat. There's also a little roller valve attached to the refill hose, and a flapper adjustment, both intended to give you ways to save water. It’s also very easy to adjust for pretty much any tank size and has other adjustments you normally don’t get with other units.
