Biofilm is an odor causing bacteria that can adhere to the inside of plumbing lines. If not properly treated, all water lines become coated with bacteria that grows at room temperature and contaminates the water. We have taken steps to make sure that the water coming from our waterlines is bacteria free. We use a system called Sterisil. The Sterisil is engineered to prevent the growth of odor causing bacteria and provide safe and clean water to our patients.
