Glendale's Water Services Department runs the city sewer, while the pipes inside your home and the line out to the city main are yours to keep clear. When a sink, tub or toilet backs up, a plumber can find the blockage and clear it. Call the number on this page to be connected with a local plumber in Glendale.

Why do older Glendale homes clog more often?
Housing data put the median Glendale home at 1985, which means a good share of the city was built before plastic drain pipe became the norm. In those houses a plumber may find cast iron under the slab, where rust scale and rough interior walls catch grease and paper, and clay or older pipe in the yard, where joints can shift and let in roots. Newer homes still clog, but the cause is more often what went down the drain than the pipe itself. If your house is older and the same line keeps backing up, ask about a camera inspection after the clog is cleared.
Is a backed-up main my problem or the city's?
Glendale Water Services handles wastewater collection and treatment for the city. As a rule, a clog in your fixtures or your building sewer is a private repair, and a plumber starts there. If the plumber clears your line to the property edge and water still will not flow, or you see sewage coming from a manhole in the street, the problem may be in the public main and the city should be called. One wrinkle: homes in the Hedgepeth Hills area between Loop 101 and Mohawk Drive, 47th to 51st Avenue, are City of Phoenix water customers, so check your bill before calling about water service there.
Will drain work in Glendale need a permit?
Clearing a blockage with a cable or jetter is service work. Glendale Building Safety says replacing drain or waste piping does require a permit, so if the plumber finds a broken or collapsed section that has to come out, permit work is part of the fix. A plumber who does that kind of repair should handle the application.
A local note
Some lots in downtown Glendale receive non-potable irrigation water from Salt River Project. That water runs in its own system and is not part of your sewer, but standing water from irrigation in the yard can be confused with a leaking cleanout. If you see water at the cleanout cap on a day without irrigation, call a plumber.
