Residents who received a survey from Aqua Backflow about how their water supplies are connected to the public delivery system are urged to respond promptly and set up an inspection.
Federal and state regulations require every municipal water supplier to make sure all customers have devices installed to prevent water already inside the structure from flowing back into the public water supply, which may create contamination issues.
Residential and commercial backflow preventers are required in a range of applications, including lawn irrigation, fire sprinklers, hot water heating, swimming pools and water features. Some require annual testing and maintenance by a licensed plumbing contractor at the property owner’s expense.
