$51.95~~$60.94~~

Detailed Description

The Green Drain GD104 is a 4-inch waterless floor drain trap seal built for commercial and residential settings where infrequently used floor drains are susceptible to drying out and allowing sewer gases, pests, and harmful aerosols into occupied spaces. Constructed with a UV-resistant ABS plastic frame and a silicone rubber sealing flapper featuring four flexible sealing ribs, it installs with a simple press-fit into existing 4-inch drain openings with no tools or modifications required. The one-way valve design permits water to flow freely at up to 73 GPM while providing reliable sewage backflow protection and blocking odors, insects, radon gas, and harmful biological aerosols. Its waterless operation eliminates reliance on a constant water supply, making it a practical green technology solution that supports LEED certification efforts and improves indoor air quality across commercial kitchens, mop rooms, HVAC areas, and more.
