    • great value, works well
Size: Universal to Fit 99% of Toilets Style: Fill Valve
Universal fit, whisper-quiet, and simple install.This completely solved my noisy, running toilet issue. True to its promise, it features a universal design that fits perfectly with zero hassle. The height adjustment is incredibly easy to set, and it fills the tank in complete silence.

    • Works great with no leaks or fuss.
Size: Universal to Fit 99% of Toilets Style: Fill Valve
Easy to install, fit well in a Glacier Bay toilet (smaller tank size but had no compatibility issues). Seals perfectly well with hand-tightening, had no issue adjusting the length to make sure it filled up to the line on the overflow tube. It came with a little metal clip that grabs onto the overflow to direct water into it. It looked like it was kind of far but it's actually designed to have the water flow perfectly out of it. I cut the black tube to size in my case so it wouldn't push the device too hard. Had a few leftover pieces at the end. It even comes with a piece that will break off if you mess with the fill valve length adjustment (for tenant, apparently). ... show more

    • Korky for Toilet Tank.
Size: Universal to Fit 99% of Toilets Style: Fill Valve
Toilet went the other day. After fighting with the old one I decided to replace it When I saw the Korky it was a no brainer. I have always used these in the past. So It took 15 minutes to install. It fits great and the water flow is powerful. It came with everything I needed. They last a long time. Very quick and works great. ... show more

    • Good price and easy to install
Size: Universal to Fit 99% of Toilets Style: Fill Valve
I bought two for my house. Installed both and they are working fine. The design looks interesting can be adjusted based on how much water to be used. One installed, that adjustment is not easy.

    • Excellent budget valve
Size: Universal to Fit 99% of Toilets Style: Fill Valve
I replaced my fluid master that was intermittently sticking. Simple plug and play, about a 20 minute job and no leaks so far. Easy to adjust the water levels of tank and bowl. Appears to have fewer parts and seems to be working as it should. Not any noiser than the old one. Can recommend so far.
