Dealing with a running, slow-filling, or noisy toilet? This Korky 528T Fill Valve is made to fix those issues in TOTO G-Max and Power Gravity toilets. The pack includes two valves, so you've got a spare or can do multiple bathrooms. It's designed to be quieter than many other fill valves and has a higher refill rate to keep your TOTO flushing properly. Installation is tool-free and super simple: just remove the old valve, adjust the height (from 7.75 to 13.5 inches), lock it in place, and connect the refill tube. The kit comes with everything you need: the valve, tube, clip, nuts, washers, and even a tamper-proof key. With a 5-year warranty, it's a reliable fix that can save you water and hassle. Say goodbye to toilet troubles!
