Repiping in Glendale, AZ

Is my Glendale house old enough to need a repipe?

Possibly. City-data figures put Glendale's median home at about 1985, which puts many houses around the age when original copper starts to develop pinholes. Older homes near Downtown Glendale can have galvanized steel supply lines, which rust inside until flow drops off. Newer homes in the northern and western parts of the city usually have copper or PEX and rarely need a full replacement.

Age alone does not decide it. A plumber looks at the pattern: one leak can be repaired, but repeat leaks in different rooms, rusty water and weak flow everywhere point toward new pipe.

Does it matter who supplies my water?

A little. Glendale Water Services runs the water and wastewater systems for most of the city. The exception is the Hedgepeth Hills area, from Loop 101 to Mohawk Drive between 47th and 51st Avenues, where homes are City of Phoenix water customers. Either way, the utility's responsibility ends at the service line, and the pipe inside the house belongs to the owner. Glendale maintains a service line material inventory through its Lead and Copper page if you want to check the buried line to your home.

Some downtown lots also receive non-potable irrigation water from Salt River Project. Those irrigation lines are separate from the drinking water plumbing and should never be tied into it during a repipe.

Will the repipe need a permit?

Glendale's building permit Q&A says replacing drain and waste piping requires a permit, and gas piping work does too. The Q&A does not spell out every supply-line scenario, so the plumber should confirm with Building Safety, Codes and Services before starting a whole-house repipe. If the job also replaces drain lines, a permit is required.

A local note

Most Glendale houses sit on concrete slabs, and the original supply lines often run under the floor. Rather than breaking up concrete, plumbers usually run the new lines through the attic and down inside the walls to each fixture. That keeps future leaks out of the slab, though it means attic runs need to be supported and protected from the summer heat. Ask how the plumber handles that, and whether patching and texture are part of the price.
