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 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.
