      Allows the flow of WATER & DEBRIS while blocking GASES, ODORS & PESTS.

      GREEN DRAIN is the unique new standard for floor drain trap seals. Self-cleaning – water free – protecting against odor, gases and bugs!

      A product designed to solve problems of odor, pests and sewage buildup often seen in other commercial and industrial floor drains. Our product’s design is based off of our extremely effective and popular urinal cartridge technology, which has been tweaked to fit a much wider variety of applications. This simple, effective floor drain solution has already earned the regard of plumbers across the nation. Traditional floor drain technology poses a variety of problems in terms of maintenance and safety. The Green Drain™ solves these major problems in a big way.

      The Problem
      Plumbing systems, along with open and exposed drains are potential sources for contamination that provide a hospitable habitat for waterborne pathogens, especially for Legionella.

      The Solution
      The Green Drain™ reduces exposure to hazardous sewer gases and disease causing pathogens that harbor within drain lines and plumbing systems. It is the ecofriendly, preventative solution that will lead to improved outcomes for worker & patient health, while exceeding the lifespan of traditional chemical applicants that harm the environment.

      The threat of disease carrying pests that hide in your drains. (I.e. Drain Flies, Cockroach’s, Fruit Flies, Silver Fish)
      The need to pour pesticides, chemical applicants and deodorizers down the drain.

      Conserves Water and Water Related Expenses 
      Eliminating the need for Continuous trap primers, but not to be used in lieu of, per UPC requirements within The US.
      Dramatically decreasing evaporation within Traps.

      The risk of harmful sewer gasses intruding your facility through drain lines.
      Costly chemical expenditures.
      Plumbing related call‐outs.
      Exterminator related call‐outs and call‐backs.
      Timely drain maintenance by Facility Staff and Plumbers.
      Sewer load.
      The chemical impact on our oceans and environment.


      • Easy to install & easy to remove. No pliers needed
      • Requires no caulk or expensive installation tool
      • Saves a significant amount of time, water, costs & energy
      • The 3½” fits in the barrel of most commercial cast iron drains for an easy retrofit into existing drains


      Series inline floor drain trap seal with UV resistant ABS plastic frame, silicone rubber sealing flapper and four flexible sealing ribs. Tested and certified to the ASSE 1072 Standard and listed with IAPMO and I.C.C. Specify connection size (2″ (51MM), 3″ (76mm), 3 1/2″ (89mm) or 4″ (102mm))​

      Used in the outlet connections of floor drain bodies, or the inside of floor drain strainers to seal the opening to prevent odors, sewer gases, and insects from entering up through the floor drain grate. The Green Drain’s four flexible silicone sealing ribs ensure easy installation into openings that have variations in size. The Green Drain will open to allow drainage and close when there is no water flow. The Green Drain can be used in either new construction or retro-fit applications where trap primers were never installed.

      Prevents the following from entering through the top of floor drains:

      • Odors and sewer/radon gases
      • Insects and harmful pathogen spread

      Drain flies appear in homes, rest rooms of commercial buildings, sewage disposal plants and agricultural facilities that handle moist animal waste. Restaurants, schools and other public buildings may be avoided when drain flies are a nuisance. Bronchial asthma can be caused by inhaling fragments and dust of dead flies. Since these flies originate in filthy conditions, there is the possibility of physical transmission of microbes of human health concern. Drain flies can carry bacteria and other microorganisms from egg-laying sites to food and surfaces that come in contact with food.

      The Green Drain can help to prevent drain fly infiltration and potentially fatal cross contamination and infection spread caused by unprotected drains. The Green Drain is an economical Drain Trap Seal Device that allows water to flow down the drain while preventing Pests, Odors, and Harmful Gases/Pathogens from infiltrating the living or work space.

      Life Cycle
      Drain fly larvae grow and feed in polluted, shallow water or in highly moist organic solids prevalent in drains. The life cycle of drain flies can be completed in one to three weeks. Adults live about two weeks, with old ones dying and new ones emerging.

      The most effective way to prevent drain fly infestations is to eliminate their breeding places. Inside buildings, this would include cleaning the drain pipes, drain traps and other plumbing system components in an attempt to eliminate the bacterial scum (gelatinous rotting, organic matter) that regularly forms on the surfaces of plumbing.

      Pesticide Treatments
      There are no insecticides registered for use in drains or sewage systems, as they can cause major damage of sewer and sanitation systems. In most cases, the larvae seem to be resistant to such treatments.


      1) Remove the grate or strainer.

      Installation 1

      2) Match the opening size (2”, 3”, 3.5”, or 4”) with the product size.

      Installation 2
      3) Place the appropriate size Green Drain into the floor drain body outlet connection, or the throat of the strainer. The four flexible silicone sealing ribs ensure easy installation into openings that have variations in size.
