          Toto replacement
          I was a little hesitant about installing this Toto replacement because I thought it was be hard. It was actually easy to install all you have to do is follow instructions and I replaced value in 23 min. I also, watched Korky on YouTube with helped which helped.

            I know it looks exactly like the cheaper white Korky valve (instead of blue Toto original), but I can confirm I bought a cheap white one in the past at the same time as an expensive blue one, and the expensive blue one outlasted the cheap one. $15 extra is not much to pay for when the slow leak the cheap white one caused for days until my utility notified me of continuous water use probably costed more than $15 in water costs. This one also lets you adjust the amount of water that flows out to the bowl, where the cheap white one doesn't.

            Easy to install. Clear directions. Needed an adjustable pliers to loosen the existing nut on the bottom outside of tank and I used a razor blade to shorten/cut the water fill tube to the correct length. The new outside nut was hand tightened.

            I replaced my old Toto Fill valve with this Korky valve after the original one started making loud noise every time Its filling the tank. My original Toto valve lasted for 8 years and I'm hoping that this one will last the same or longer. This Korky valve is quiet and easy to install and adjust.Just follow the instructions that comes with it.

            Repacked the green Toto fill valve
            The fill valve was easy to install but follow the instructions carefully. The most challenging part was removing my old valve nut. After trying all my tools at no avail, I went and bought a channel lock plier which did the trick. I like the fact that I can adjust the tank to bowl ratio. Worth the extra money for this one.
