Slab Leak Repair in Glendale, AZ

Is a Glendale home likely to have one?

Glendale's housing has some age on it. City-data figures put the median home at about 1985, which means a large share of houses have copper supply lines that have been buried in or under the slab for decades. Copper in that position can wear through where it touches stone, rebar or another pipe, and a joint made during construction can let go after years of pressure swings. Slab-on-grade construction is the Valley norm, so when a line under the floor fails, there is no basement or crawl space to catch it; the water goes into the soil and up into the floor.

Could it be a drain line instead?

Yes, and the difference matters. A supply leak runs all the time because the line is under pressure, so the meter moves even when no one is using water. A leak in a drain or waste line under the slab only leaks when something drains, and it often shows up as odor, damp flooring near a bathroom, or slow drains rather than a spinning meter. Glendale's Building Safety Q and A states that replacing drain or waste piping needs a permit, so a sewer-side repair under the slab is permitted work. A camera inspection usually settles which kind of leak it is.

Who do I call: the city or a plumber?

Glendale Water Services, at 623-930-4100, handles the public side of the system. If water is surfacing near the meter or in the street, call them. If the meter shows a leak but nothing is visible outside, the leak is almost always on your side and a plumber is the right call. One wrinkle: homes in the Hedgepeth Hills area, between Loop 101 and Mohawk Drive from 47th to 51st Avenue, are City of Phoenix water customers, so their meter-side questions go to Phoenix instead.

A Glendale note

Glendale keeps a service line material inventory on its Lead and Copper page. It covers the line from the main to your home, not the pipes under your floor, but it is a useful reference if you're deciding whether to repipe an older house rather than patch one more leak.
