Annual backflow testing is not typically required for homes, but it is not unheard of either. However, most backflow assemblies are found on commercial buildings or within common areas and HOA landscaping. Local water companies notify water account holders who have backflow devices that require testing.

Why do I Need My Backflow Tested?
What is a backflow assembly?
A backflow assembly is an approved, testable assembly which uses valves, in different configurations, to prevent polluted or contaminated water from reversing direction and flowing backward into a customer’s potable water plumbing or in the municipal water distribution system.
Who is required to have a backflow prevention assembly?
Any water customer with a cross-connection is required to install appropriate backflow protection. Federal and State laws require that water suppliers protect their water systems from contamination by requiring the installation and testing of appropriate backflow assemblies. Commercial and industrial customers and homes with dedicated landscape meters are required by City Ordinance and State Administrative Code rule R18-4-215 to install, test, and maintain backflow prevention assemblies. In addition, the City of Mesa has adopted the 2006 International Plumbing Code. This code specifies backflow requirements for water customers including all single family residences.
How do I know if I need a backflow prevention assembly?
If you maintain a cross-connection on your property, you must protect your family and neighbors, as well as other water customers, from a backflow event by isolating the cross-connection as required by code with a properly installed backflow assembly. Additional guidance to this end is provided on this website. Specific questions or concerns can be addressed by calling our Backflow Prevention/Cross Connection Control mailbox at (480) 644-6462.
Backflow Repair Services
Backflow prevention assemblies are designed to provide decades of protection. There are many regional conditions that can shorten the working life of a backflow preventer. Conditions such as excessive pressure, water quality, temperature or turbidity can all cause the assembly to deteriorate in its performance. Some backflow prevention assemblies may rarely need repair while some are repaired on a regular basis. The test data from the field test will determine the repair frequency. If the repair frequency becomes excessive it is important to determine the factors that are causing the unusual repair frequency. If the cause is due to excessive turbidity (dirt and debris), then a strainer may provide a longer duration between repairs.
If the backflow prevention assembly is failing due to water quality conditions such as chloramines or temperature, replacing the existing assembly with an assembly with different rubber and material composition may solve the problem. If excessive pressure is damaging the software parts, then a pressure regulator may be needed. Evaluating not only the field test data but also the cause of the failure is important to ensure a proper repair frequency.
Backflow preventers can fail for a variety of reasons, including:
– Broken check valves
– Leaking from the relief valve
– Debris
– Worn springs
– Cracked or shifted rubber parts
– Excessive pressure, water quality, temperature, or turbidity
Backflow preventers can fail over time due to wear and tear. The most common sign of a failed backflow device is frequent water leaks.
Other signs include:
1) Drains draining slowly
2) Water leaking around the property, even after changing the pipes
Backflow preventers can fail in areas that don’t have access to treated municipal water supplies. When a backflow preventer fails, the public water supply can become contaminated with bacteria and/or viruses.
The life expectancy of a backflow preventer is 5 to 10 years. DCV assembly backflow preventers should be tested at least once every year. RPZ assembly models should be tested annually and rebuilt every five years.

Backflow Replacement
Unlike new backflow installation when there is a current backflow that needs to be replaced the Technician will get the info of the backflow in questions and find the replacement.
They will then remove the old backflow and replace it with the new one. There will most likely be some work that needs to be done on the copper pipe with either extending the opening or replacing some of the pipe that feeds into the backflow.
When the technician is there they will bring the backflow up to code for the height from the ground and the distance from the wall.

Who can install a backflow prevention assembly?
The installation of the backflow prevention assembly is the responsibility of the customer. The assembly may be installed by a property owner, plumbing contractor, or a general contractor, subject to the Rules and Statutes of the Arizona Registrar of Contractors. Permits are required to install these assemblies. Permits are issued by the City of Mesa.
-
Generally, the backflow prevention assembly must be located as close as possible to the water service connection, but must remain on private property. Individual cross-connections must be isolated with a properly installed backflow assembly at the connection point to the potable water supply.
-
It is the sole responsibility of the customer to ensure that the assembly is in satisfactory operating condition at all times. The City of Mesa Water Resources Department will send notices to regulated customers advising them when an annual test is required on their backflow assembly. The customer must contact a recognized Backflow Assembly Tester to perform the test. If any repair work or maintenance is performed on the assembly, a recognized Tester must retest the assembly immediately and submit the test results to the City of Mesa.
When a backflow needs to be replaced we will get a permit from the city your business is located in and work with you on time of installation as we will have to turn the water off for the building unless there is a water shutoff before the backflow preventor.
