Key benefits Prevents odors and leaks: well-sealed construction blocks sewer gas and resists dripping for a cleaner, safer sink area. Flexible, space-saving routing: retractable and bendable design lets you shape the pipe to avoid obstacles and maximize under-sink space. Simple installation and compatibility: works with sinks that have or do not have an overflow, and installs quickly without complex modifications. What’s included Each package includes 1 plumbing kit. Main features Flexible and adjustable: extendable/retractable length and multi-directional bendability let you route the drain around plumbing traps, cabinets, and other obstructions. Leak-resistant seal: designed to maintain a tight seal at connections to reduce the risk of leaks and unpleasant odors. Compact design for small spaces: ideal for compact vanities and crowded under-sink areas where rigid piping is difficult to fit. Universal application: suitable for kitchen sinks, bathroom sinks, bathtubs, and other standard household fixtures that require a flexible drain connection. Performance and compatibility Fits installations with or without overflow openings. Adjustable shape allows you to customize the connection to match the available space and existing plumbing layout. Provides reliable drainage performance while simplifying maintenance and replacement. Practical use scenarios Kitchen sink retrofit: reroute the drain around a disposal unit or cabinet shelving without replacing rigid pipes. Small bathroom vanity: fit a compact sink into a tight cabinet by bending and shortening the pipe to avoid the back wall or storage compartments. Bathtub or utility sink: create a custom drain path in older or nonstandard installations where fixed-length piping does not align. Installation tips Align and attach to the sink outlet, adjust length and bends to clear obstacles, then secure connections to ensure a tight seal. Check all joints for tightness after installation and run water to confirm proper drainage and no leaks. This flexible sewer pipe provides a practical, adaptable solution for common drain problems, combining odor protection, leak resistance, and space-saving flexibility in one plumbing kit.
