COLDDD Water-sealing Drain Core
SFDL Instructions
Designed for superior odor control and backflow prevention. Equipped with an expanded rubber ring, it fits drainage openings with diameters of 1.5 to 2.0 inches. With its advanced water-sealing principle, it keeps your space fresh and clean. Made from durable 304 stainless steel, it's easy to install and maintain, making it perfect for bathrooms, kitchens, and more.
Why does water remain at the bottom of the drain core?
The drain keeps a bit of water at the bottom to stop bad smells and water from flowing back. This water barrier is like a mini-pond that gets refreshed every time you use the drain.
How should I choose between the 2.4‘’ and 3.3‘’ depth specifications?
The deeper the specification, the more water it holds. If you're going to be away on a trip or business for an extended period without draining, the deeper specification will maintain the odor control for a longer time.(2.4''-20days ; 3.3''- 40days )
