Green Drain Inc GD3 Details

Never fear a dry drain trap again when you use this Green Drain GD3 3" waterless trap seal! This patented seal allows the flow of water and debris out through a floor drain while preventing pathogens, gases, odors, and pests from finding their way back into your commercial building by way of an infrequently-used drain. An innovative solution for industrial and commercial buildings, this waterless trap seal is easy to install and remove when needed, and provides time, water, and cost savings for your business.

This waterless trap seal fits floor drain pipes 3" in diameter and allows water to flow through at a rate of 34 GPM. It is made of durable UV-resistant ABS plastic for long-lasting use, and features a silicone sealing flapper and four flexible sealing ribs that ensure a proper fit. Whether you are outfitting new construction or retrofitting an existing space, this waterless trap seal can be used in either application.

When you want to ensure good indoor air quality and better sanitation in your commercial building, this trap seal with its one way drain valve helps you achieve your goal. It prevents drain odors, sewer / radon gas, or harmful biologic aerosols from infiltrating your building. Plus, it also helps to keep pests out. This is especially important to consider when drains are used infrequently so that the water in the traps evaporates, allowing odors and contaminants to escape.
