Does your bugs, foul odors, or sewer gas emitting from your facility floor drain? Drain-Net offers a number of simple solutions to prevent this common drain problem. Both the Green Drains and the Drain Lock with Odor and Bug blocker feature one way drain valves to let water drain, while preventing odors and bugs from escaping the drain.
