Score: 85/100Rankings
The Danco FLT231T HydroStop is a flapperless toilet repair kit that replaces traditional rubber flappers with a sturdy vertical-closing tower mechanism. It utilizes patented S.T.O.P. Technology to prevent bowl overflows and features a chemical-resistant silicone seal with a stainless steel cable. Ideal for homeowners seeking a permanent solution to leaking toilets.
The Fluidmaster 5401GBP4 is a durable 3-inch adjustable silicone flapper designed primarily for Glacier Bay and similar high-efficiency toilets. Its main limitation is its lack of universal fit, making it less suitable for non-compatible brands. It is best suited for owners of Glacier Bay toilets seeking a long-lasting upgrade with water-saving adjustability.
