Chandler businesses get water and sewer from the City of Chandler, which also requires backflow devices to be installed, maintained and inspected, and permits run through the Development Services Department on Buffalo Street. Hard water and busy restrooms keep commercial plumbers here steady. Call the number on this page to be connected with a local plumber in Chandler.

How Chandler's system shapes commercial work
The City of Chandler runs water, sewer and solid waste, all billed through Chandler Utility Services at 480-782-2280. Water reaches buildings from the Pecos plant, which treats Salt and Verde River water from the Consolidated Canal plus CAP water, from the Santan Vista plant shared with Gilbert, and from city wells. Disinfection is chlorine rather than chloramine. The city puts hardness anywhere from about 5 to 20 grains per gallon depending on the area, with a citywide average of 16.5, and that is hard enough to cut into the efficiency of storage heaters, boilers and steam equipment.
The city requires backflow prevention devices to be installed, maintained and inspected wherever a property could push contamination into the mains, and that includes lawn irrigation. The city's line for inspections, meter sets and hydrant leaks is 480-782-3700. Permits come from the Development Services permit counter at 215 E. Buffalo St. (480-782-3000), with inspections scheduled at 480-782-3100. Chandler's service line inventory has not turned up any lead service lines. Gas comes from Southwest Gas; anyone who smells it should leave the building, then call 911 and Southwest Gas at 877-860-6020 from outside.
Repair now or plan a replacement
| Situation | Often a repair | Often a replacement or upgrade |
|---|---|---|
| Commercial water heater | Element, thermostat or relief valve fails on a younger unit | Heavy scale, tank leak or demand that outgrew the unit |
| Restroom fixtures | Flush valve diaphragm or sensor trouble | Cracked china or an outdated layout during a remodel |
| Kitchen drain line | A grease plug cleared by cleaning or jetting | Repeated stoppages from a sagging or broken section |
| Backflow assembly | A failed check or relief part replaced and retested | A body that is damaged or no longer meets the requirement |
Signs to act on
- Restaurant drains that gurgle or back up after a full service
- Tenants reporting lukewarm water by mid-afternoon
- Irrigation backflow devices dripping or spraying at the relief port
- Damp drywall behind a restroom wall or under a breakroom sink
- Meter readings climbing while the building is closed
Timing and seasonal notes
Many Chandler buildings are from the late 1990s on, since the citywide median year built is 1997, so original water heaters, valves and flush hardware are reaching the age where they fail in clusters. Summer heat pushes cooling towers, ice machines and irrigation hard, which is when weak backflow devices and supply valves tend to give out. Scheduling a heater flush or fixture rebuild for a slow season, or before a lease turnover, keeps the work off your busiest days.
