Why does my toilet keep running and how does this kit fix it?A constantly running toilet is usually caused by one of two problems: a faulty flapper or a malfunctioning fill valve — both of which are included in this kit.

Problem 1: Faulty Flapper — The flapper is the rubber seal at the bottom of the tank that holds water in until you flush. Over time, flappers warp, harden, or develop mineral buildup, preventing them from sealing properly. Water slowly leaks from the tank into the bowl, and the fill valve periodically turns on to refill the tank (sometimes called "phantom flushing"). The 502 Flapper in this kit creates a tight seal and features an adjustable dial to optimize flush volume.

Problem 2: Faulty Fill Valve — The fill valve controls water entering the tank after a flush. When it wears out, it may not shut off completely, causing water to continuously run into the tank and down the overflow tube. The 400A Fill Valve in this kit is the industry standard for reliable, quiet operation and features anti-siphon technology required by plumbing codes.By replacing both components (plus the flush valve, lever, and hardware), this kit addresses virtually every cause of a running toilet and gives you a completely rebuilt tank that should work trouble-free for years.
