The State of California requires backflow devices to be tested for proper operation annually. The City of Perris notifies owners of testing requirements each year; a list of certified testers acceptable to the State is included with the notice. Failure to correct any deficiencies and demonstrate passing results is a cause for potential cross-connections and may result in the termination of water services. Our request complies with City’s Municipal Code (1972, § 14.10.080; Ord. No. 1196, § 2(part), 2006), which states that upon the city’s determination that a clear and immediate hazard to the city’s approved water supply exists, the city shall make a reasonable effort to advise the involved responsible owner or water user of the necessity for and its intent to, immediately discontinue/terminate water service.

While single-family residences are not generally required to have a backflow device, you can help prevent backflow contamination in the following ways:

• DO NOT leave hoses attached or submerged in unsafe water such as fertilizer or cleaning solution.
• Confirm that anti-siphon type irrigation valves are installed on irrigation valves.
• Install a hose bib vacuum breaker. Please note that most new homes are already equipped with anti-siphon faucets.
