Compact, leak-preventing seal: The sealing plug’s compact structure forms a reliable seal for sink sewer outlets, preventing water leakage and helping keep counters and cabinets dry. Three functions in one device: Acts as a sealing plug, a debris filter, and a deodorizing cap for sewage outlets—reducing odors, blocking backflow, and stopping solids from entering the drain. Tool-free installation and replacement: Designed for quick, hands-on installation without extra tools or parts. Remove and replace the plug easily for cleaning or maintenance. Effective debris filtration: Built-in filter screen captures food residues, hair, and other solid particles before they enter the sewer pipe, decreasing the risk of clogs and slow drains. Practical performance and maintenance: Compact design fits into sink sewer outlets and sewage outlets while staying out of the way. The plug is simple to remove for rinsing or clearing trapped debris. Where it helps most: 1. Kitchen sink while washing dishes or prepping food — catches scraps and prevents leaks around the drain. 2. Utility or laundry sink — prevents solids from entering drain lines and reduces odors. 3. Bathroom sink or vanity — traps hair and debris and minimizes unpleasant smells from the drain. Why customers choose it: Solves common sink problems—leaks, odors, and clogs—without complicated installation or extra tools. Its integrated design replaces the need for separate covers, strainers, and deodorizing devices. Note: Designed for use with sink sewer pipes and sewage outlets as described; remove and clean regularly to maintain filtration and sealing performance.
