Fluidmaster’s PerforMAX toilet fill valve and 2” flapper kit includes a fill valve and solid-frame flapper with built-in adjustability so water levels can be fine-tuned for a stronger flush. Fluidmaster’s PerforMAX toilet fill valve and 3” flapper kit includes a fill valve and flapper with silicone seal that lasts up to 10 times longer than standard flappers. The PerforMAX toilet fill valve and specialty seal kit is designed to replace tower (piston-style) systems, which can be identified by the tower object with a round colored seal where the flush valve opens and lets the water out of the tank.
