Fluidmaster 523A Universal 2” & 3” Super Flapper
Every retailer dreads the cycle of frustrated customers returning the wrong part, exasperated after multiple trips to the store, only to find out they’ve once again purchased the incorrect size. The plumbing department frequently contributes to this issue. Enter the Fluidmaster 523A Super Flapper, a simple yet innovative solution that eliminates guesswork and ensures a proper fit for most toilets.
One of the biggest pain points for customers replacing a flapper is determining whether their toilet uses a two- or three-inch valve. Many toilets manufactured before 2005 typically use a two-inch flapper, while newer models, especially high-efficiency toilets (HET), are likelier to have a three-inch flush valve. However, this isn’t always the case. The Super Flapper resolves this with its universal adjustable design. It easily adapts to both two- and three-inch flush valves, ensuring that customers don’t have to worry about picking the wrong size.
The Super Flapper is built for performance and water efficiency. Its adjustable dial allows users to customize the flush rate, optimizing water usage based on their toilet model. With the EPA’s WaterSense® program encouraging water-saving measures, homeowners can fine-tune their toilet’s performance to prevent water waste. By improving flush efficiency, this flapper helps homeowners lower their water bills while maintaining a strong and reliable flush, preventing common problems like weak or incomplete flushing.
