The Fluidmaster 502P21 PerforMAX flapper is pretty versatile and should fit most toilets that use a 2-inch flush valve. But although it's labeled as 'universal,' it's not guaranteed to work with every single toilet out there. For instance, some Toto and certain Kohler models might need a different size or setup.
The manufacturer suggests it's great for high-efficiency toilets with flush rates between 1.28 and 3.5 gallons per flush. However, from our research, we found that some folks had trouble with it fitting perfectly in their specific toilet. To avoid any hassle, it's a good idea to measure your toilet's flush valve size before buying.
The flapper is designed with an adjustable dial that lets you tweak the water flow, which can help save water—a nice bonus if you're looking to cut down on your water bill. It's made of corrosion-resistant materials and includes Microban protection against bacteria and chlorine, which should help it last longer, even in tougher conditions.
Installation is usually quick and takes less than 10 minutes, so if you like simple DIY projects, you'll probably find setting this up pretty straightforward. Many people mention how easy it was to install and how well it stopped leaks. Plus, the water-saving feature is a hit, helping maintain a good seal for efficient flushing.
But, it's worth mentioning that while most feedback is positive, there are a few reports about fitting and durability issues, especially with hard water. If your toilet has an unusual setup or diverges from the standard 2-inch valve, it's wise to double-check the measurements and compatibility before buying.
Overall, the Fluidmaster 502P21 is popular and effective for a lot of folks, but making sure it fits can save you from any headaches down the line.
