Extended Floor Drain with multilayer stainless steel pipe and builtin backflowprevention Key benefits Durable, longlasting construction: Multilayer stainless steel pipe design resists breakage and corrosion so the drain maintains reliable operation over time. Prevents wastewater backflow: Builtin backflowprevention mechanism automatically seals when no water is present to stop wastewater from flowing back, and opens smoothly during drainage for continuous use. Fast, reliable drainage: Straightdrop internal structure minimizes resistance and allows rapid water flow, keeping drainage consistent even under heavy load. Easy, flexible installation: Simple pushfit setup with an adjustablelength flexible connector for broad compatibility with common pipeline heights. What makes it practical Function and performance: The straightdrop internal path directs water straight into the drainage system for efficient outflow. The automatic sealing system protects against odors and backflow without manual intervention. Material and durability: Multilayer stainless steel construction provides structural strength and long service life while resisting damage and wear. Compatibility and sizes: Fits a range of pipeline heights and configurations — compatible with 146*72mm, 56*72mm, 86*72mm, and 116*72mm setups. The flexible connector adapts to small variations in alignment and length for a straightforward pushfit connection. Installation and use Pushfit connection for quick fitting and adjustment on site. Adjustable flexible connector accommodates differences in pipeline height and positioning. Opens automatically when draining and reseals when idle for maintenance backflow protection. Typical applications Residential bathrooms and shower areas where reliable, fast drainage and backflow protection are required. Laundry rooms and utility areas that need a durable drain able to handle frequent, heavy water flow. Commercial kitchens, service areas, or small commercial facilities where corrosion resistance and consistent drainage performance are important.
