Backflow Testing in Gilbert, AZ

What happens when you call

The number on this page connects you with an independent plumber who works in Gilbert. Start by saying what prompted the call: a notice, a leak, a failed result, or a project such as a new irrigation system, a pool fill line or equipment in a shop or home business. Then describe the device if you can see it, including the brand and size stamped on the body and whether it has test cocks. The plumber will tell you whether the job is a test, a rebuild, a replacement or a new install, and whether Town inspection is likely to be part of it.

If the device is spraying, close the irrigation valve or the main shutoff before the call. Don't cap a relief port; that defeats the protection.

Cost factors

• Scope. A test on a working device is the smallest job. Repairs, a retest and replacement add up from there.
• Device type. A reduced pressure assembly has a relief valve and two checks to service; a pressure vacuum breaker is simpler.
• Size. Larger commercial assemblies take more time and cost more in parts.
• Location. Internal assemblies inside a building or ceiling space can take longer than one in a front-yard box.
• Inspection. New installs may need a Town permit and inspection.

Local conditions in Gilbert

Gilbert runs its own water utility, blending Salt River Project and Central Arizona Project surface water with groundwater from Town wells. Backflow is handled on the building side of the Town by Development Services, under Inspection and Code Compliance. The program's emphasis on internal assemblies means devices aren't only at the meter: lines inside a building that feed equipment, chemical systems or other hazards can need their own protection. Questions go to the Town's backflow inspection specialists at (480) 503-6714 or (480) 503-6715, and general permit questions to the One Stop Shop at (480) 503-6700.

The Town pages reviewed don't state a test interval for a typical single-family home, so check with the specialists if you are unsure whether a device at your address is on a schedule. Housing in Gilbert is fairly young, with a median year built around 2003, and many homes from the Heritage District out along Higley Road have irrigation devices that have never been rebuilt.

Before the plumber arrives

• Find the device and clear plants or gravel around it
• Locate the shutoff for irrigation and for the house
• Have any Town notice or past test report on hand
• Note any chemical injectors, pool fills or equipment tied to the supply
