However, the benefit of a functioning backflow preventer is the protection of health of those in proximity to it, as well as other water customers in the area (i.e. The cost of installation and testing is often paid by the water customer.

If a water customer has a cross connection protected by a testable backflow preventer, they may expect a letter from the water system periodically requesting it to be tested by a professional tester with ASSE 5110 certification. Failure rates of protective devices can be substantial in some communities and vary based on several factors. As with any mechanical device, backflow preventers have been shown to fail. Some types of backflow preventers require periodic testing at some frequency to ensure they are functioning properly. A local water system cross connection inspector should have the specialized training necessary to identify cross connections and determine what level of protection is needed. There are many types of backflow preventers, and it is important to match the chosen backflow prevention method with the specific situation. The basic function of a backflow preventer is to stop water from flowing backwards.

A common way to control a cross connection is to install a backflow preventer.

In order to protect public health from the risk of backflow, the SDWA works together with the Michigan Plumbing Code requirements to control cross connections. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) oversees public water supply programs to identify and prevent cross connections throughout Michigan. To identify and prevent cross connections in community water supplies, Part 14 of the Michigan Safe Drinking Water Act Administrative Rules (SDWA) prohibits cross connections and requires each water supply to implement a cross connection prevention program including inspections, testing, recordkeeping, and education. Cross Connection Prevention In MichiganĪ cross connection is an unprotected plumbing arrangement through which backflow can occur. These backflow events have resulted in documented contamination in water systems across the country, but most cases of backflow are left undetected. These are examples of backflow, and contamination during a backflow incident can occur through the plumbing and points of use. Other times, pumps or water heating devices in homes and businesses can overcome the water system pressure. This can result in siphoning of unknown materials into the drinking water. Though difficult to detect, water pressure can sometimes be disrupted causing water to accidentally flow backwards. This helps ensure contamination cannot enter the system through points of connection or leaks. Water distribution systems are designed to operate with continuous positive pressure.
