Safe, chemical-free clearing: Designed to remove blockages without corrosive cleaners. The built-in pressure relief safety valve reduces the risk of sudden overpressure for safer operation in sinks, pipes and drains. Replaces harsh methods: Provides an effective alternative to chemical drain openers and plungers/pistons, delivering strong clearing power without exposing you or surfaces to toxic substances. Multi-purpose performance: Clears hair, fabric fibers, tea leaves, leaves, grease and similar debris from kitchen sinks, bathroom drains, shower channels and small pipes. Complete size set: Includes four interchangeable suction cups in 5 cm, 6 cm, 11.5 cm and 20.5 cm to match a wide range of drain openings and pipe sizes for better sealing and more effective clearing. Simple and reusable: Easy to attach and switch suction cups to match the problem; reusable for repeated use without additional supplies or chemicals. Practical compatibility: Works on sinks, floor drains, shower drains and many standard pipe openings where a tight suction seal can be formed. Typical use scenarios: Kitchen sink clogged with grease and food particles: Select the appropriate suction cup to form a tight seal over the drain and clear the blockage quickly without chemical cleaners. Bathroom hair and fabric build-up: Use the smaller suction cups to target shower or basin drains and remove hair and lint safely and effectively. Tea room or utility sink with leaves or debris: The larger suction cup covers wider openings to dislodge lightweight debris and restore flow. What you get: A chemical-free drain clearing kit with a pressure relief safety valve and four suction cups (5 cm, 6 cm, 11.5 cm, 20.5 cm) to handle common household blockages safely and repeatedly.
