Josam offers a waterless trap seal for floor drains. TSI® can be used in outlet connections of floor drain bodies or the inside of floor drain strainers in commercial facilities such as restaurant kitchens, bars, and food-processing facilities to help seal the drain opening and preventing odors, sewer gases, and insects such as drain and fruit flies from entering up through the floor drain.
Available in 2″, 3″, 3.5″ and 4″ sizes and can be used in either new construction or as a retrofit. TSI® has a one-way valve that eliminates the odors while allowing water to pass through. It features an attached silicone skirt that prevents insects and rodents from entering. Installation of the TSI® is quick and easy and eliminates the need for chemical applications and excess water needed for treatments, saving time and money. Trap Seal Insert solutions help increase indoor air quality, protect the public health, and provide sewage backflow protection while preventing drain odors, pest infiltration, sewer/radon gas infiltration, and harmful biologic aerosols. It has been tested by ASSE, UPC, and ICC-ES. Click here to visit the TSI® product page https://www.josam.com/catalog/JOS/pl=TA/88240
