Water is the traditional method of sealing out noxious gases from working/living areas in North America. Traditional trap primers allow approximately 4oz of water to enter the drain every time a toilet/urinal is flushed. This is a HUGE waste of water.
SureSeal is a waterless trap barrier that prevents sewer odors and insects from entering living/working areas. SureSeal meets and surpasses ASSE1072, opens with 4 ounces or less of water and won’t reduce nominal drain flow.
