Frequently Asked Questions
Q: What drain sizes is this self-closing drain core compatible with?
A: This drain core is designed for standard 3-inch round floor and sink drains. The unit measures approximately 7 × 8 cm (2.75 × 3.15 in), making it a fit for most common household bathroom and kitchen floor drains. Please measure your drain opening before purchasing to confirm compatibility.
Q: How does the odor-proof and insect-proof feature work?
A: The drain core uses a gravity-activated silicone seal. When water is not flowing, the self-closing flap seals shut, blocking sewer gases and small insects from traveling up through the drain pipe. When water flows through, the weight opens the flap to allow proper drainage, then it closes again automatically.
Q: How do I clean the drain core?
A: Simply lift out the removable inner stainless steel strainer and rinse it under running water to remove accumulated hair and debris. The outer body can be wiped clean with a damp cloth. No special tools are needed for removal or reinstallation.
Q: What materials is the drain core made from?
A: The drain core is constructed from a combination of ABS plastic, food-grade silicone (for the sealing flap), and stainless steel (for the strainer and top cover). The stainless steel surface is electroplated for added durability and a polished appearance.
