Backflow Testing in Mesa, AZ

Signs it is time for a backflow visit

• A letter or email from Mesa Water Resources says a test is due on an assembly at your property
• Water drips steadily from the relief port or a test cock while the irrigation runs
• An earlier tester left a failed result and the repair never got scheduled
• You are adding drip zones, a pool fill line or a fertilizer injector to the landscape system
• Outdoor zones lost pressure after someone worked on the valve
• The brass body is cracked, green with corrosion or crusted with white mineral scale

How the rules work in Mesa

Water and sewer in Mesa come from the City of Mesa, so its Water Resources Department sets the cross-connection rules. The program document is specific about who may do the work: the tester must be recognized by the city under Mesa City Code 8-1-4C, must use a gauge calibrated every year, and must follow the USC Manual of Cross-Connection Control. After the test, the report goes in through the city's online tester portal within ten business days. Questions about a particular assembly go to the program at 480-644-6462 or [email protected].

Mesa water is hard. The city's water quality report puts the average near 12 grains per gallon in the City Zone and about 16 grains in the Eastern and Southern Zones. Scale on check valve seats and relief valve parts is a common reason an aging assembly stops holding a clean reading, whether the house is near Downtown Mesa or out by Phoenix-Mesa Gateway Airport.

A new install or a relocation is a permit question for Mesa Development Services, Permit Services, at 55 N. Center Street.

What shapes the price

• Test only, or test and repair. A device that passes on the first try is a short visit. A leaking relief valve or a check that won't hold means parts, labor and a second test.
• Assembly type and size. A reduced pressure assembly has more internal parts than a pressure vacuum breaker or a double check.
• Condition. Heavy scale or a split body can make replacement more sensible than a rebuild kit.
• Access. A device buried in shrubs or set low inside a box takes longer.
• Paperwork. Filing through the portal is part of the job; ask whether it is included.

What happens when you call

The call connects you with an independent plumber who works in Mesa. Keep the notice handy, say whether the device serves irrigation, a pool, a fire line or a business, and ask the plumber to confirm they appear on the city's recognized tester list. If water is pouring out of the assembly, close the irrigation valve or the main shutoff until help arrives.
