Special Features

  • PERFECT FIT FOR 3-INCH DRAINS: Specifically engineered to fit standard 3-inch general-purpose floor drains and pipes (PVC/ABS). Ideal for upgrades in basements, laundry rooms, bathrooms, and garage floor drains. (Please measure your drain opening diameter before purchasing).
  • SUPERIOR SPRING-LOADED MECHANISM: Unlike common silicone "duckbill" seals that rely on soft rubber memory, our core features a durable 304 stainless steel spring. This active mechanical design ensures the valve snaps tightly shut every time, preventing deformation and aging.
  • HIGH FLOW & ANTI-CLOG DESIGN: The hinged flapper opens fully up to 90 degrees under water pressure, achieving a rapid drainage speed of up to 1.1 L/S (17 GPM). This high-capacity flow allows water and debris to pass through instantly without backing up, solving the slow-draining issues often seen with restrictive silicone diaphragm seals.
  • EFFECTIVE ODOR & BACKFLOW BLOCKER: Keeps your home fresh by tightly sealing against sewer gas and bad smells. The strong spring tension also acts as a reliable backflow preventer, stopping wastewater from rising back up during heavy rains.
  • TOOL-FREE INSTALLATION: No plumber or tools required. Simply remove your existing drain grate and press this seal into the pipe. The high-quality rubber gasket ring ensures a snug, leak-proof fit instantly.
