Chandler is a separate city with its own municipal water and sewer utility, so Chandler homes are not on City of Phoenix water and plumbing permits come from Chandler's Development Services Department. Plumber Phoenix is a free referral line, not a plumbing company. Call the number on this page to be connected with a local plumber in Chandler.

Where Chandler sits in the East Valley
Chandler is a Maricopa County city in the southeast part of the metro, about 17 miles from downtown Phoenix as the crow flies. It was founded in 1912 and incorporated in 1920, and the 2020 Census counted 275,987 residents. Interstate 10, State Route 87, the Loop 101 Price Freeway and the Loop 202 Santan Freeway all cross or edge the city. Downtown Chandler is the historic core, while the area around Chandler Fashion Center and the newer master-planned subdivisions show how much of the city went up in recent decades. Large employers such as Intel and Northrop Grumman make it a tech and commercial center as well as a suburb.
A city utility with several water sources
The City of Chandler bills residents for water, sewer and solid waste through Chandler Utility Services (480-782-2280). Supply is a mix. The Pecos Water Treatment Plant treats Salt and Verde river water from the Consolidated Canal plus Central Arizona Project water and SRP well water, the Santan Vista plant (shared with Gilbert) treats CAP water from the Colorado River, and city wells add groundwater. All of it is disinfected with chlorine rather than chloramine.
Hardness is the plumbing issue people notice. The city says it runs from roughly 5 to 20 grains per gallon depending on the area, with a citywide average of 16.5. That level of minerals builds scale inside tank and tankless water heaters, clogs aerators and shower cartridges, and is a big reason softeners are common here. On the safety side, Chandler keeps a service line material inventory and says it has not found any lead service lines.
Permits and gas
Development Services runs the permit counter at 215 E. Buffalo St. (480-782-3000). The city's homeowner permit manual lists like-for-like replacement of a residential water heater or water softener as exempt from a building permit, while adding a gas line inside the house needs a permit with a gas riser schematic, and irrigation systems and plumbing beyond ordinary repairs need permits too. Chandler also requires backflow protection on residential lawn irrigation, typically a vacuum breaker, or a reduced pressure assembly where chemicals are injected.
Southwest Gas serves Chandler. If you smell gas, leave the house first, then from outside call 911 and Southwest Gas at 877-860-6020.
Housing and what is different from Phoenix
The median Chandler home was built around 1997, so the typical call involves slab-on-grade houses with copper or PEX supply lines, water heaters worn down by scale, and irrigation valves rather than old galvanized piping. Compared with Phoenix, the main differences are the utility (Chandler, not the Phoenix Water Services Department), a harder average water supply, and Chandler's own permit rules. When you call, say what is leaking or backing up and whether the water is off at the meter, and you will be connected with an independent plumber who works in Chandler. Cost and timing are set directly with that plumber.
