how often should backflow devices be tested
Simply put, a backflow preventer is a one-way gate for water. These devices are crucial in all aspects of water on your property â whether youâre thinking of water coming into your home or in your irrigation and sprinkling system. How Often Should Backflow Preventers be Tested? Ideally, backflow preventers should be tested at least once per year. You should receive a notice from the City of San Diego Water Department about 45 days before your testing is due. Theyâll send a reminder roughly 15 days before the due date. If there is no response, you may experience a loss of service. Let Juniper Landscape Company Install and Test Your Backflow Preventer
