•Excellent Anti-Backflow PerformanceA high-performance one-way drain pipe valve that is expertly-crafted to allow liquids to flow in only a single direction and prevents nasty sewage backup. Featuring a smart automatic rebound design that opens 90° during draining and quickly closes tight when water pressure is gone. It ensures that water won’t get clogged and runs smoothly anytime without the need for manual operation anymore. Additionally, this drain gasket also offers an incredible sealing effect to successfully block-off liquids from coming out and spilling through the connection. Making it the perfect piping addition to discharge liquid without backflows and keep water lines from wastewater contaminants for a hygienic wash cycle. 

•Maximum Odor-Sealing EffectThis reliable anti-backflow laundry pipe gasket adopts an incredible air-tight sealing quality. It effectively stops strong sewer-smelling gasses from leaking out and permeating everywhere in your living space which can lead to respiratory problems. The washing machine drain valve also comes with a multi-layer sealing ring for a much better odor-blocking ability. Furthermore, its automatic rebound plugging also works to guarantee that no insects and pests could climb up after draining. Eliminating the risk of pesky creepy crawlers from invading your home and causing food contamination, spreading of disease, property damage, and various health issues.
