Sewage backing up right now? The first hour
- Stop using water everywhere in the house: no flushing, laundry, dishwasher or showers. Every gallon goes into the blockage.
- Keep people and pets away from wastewater. Open windows.
- Check if it is the City's side. If neighbors are backing up too, or sewage is coming out of a manhole in the street, report it to Phoenix Water Services: 602-262-6691 weekdays, 602-261-8000 after hours (City of Phoenix).
- If it is only your house, the blockage is almost always in your line. Call us and a licensed contractor can clear it and camera it.
Clog or broken line? Signs to watch for
One slow sink is a fixture clog. Multiple drains together point to the main sewer line. Repeat clogs on the main line usually mean something physical is wrong: roots, a broken joint, a sag or collapsing pipe.
- Several drains back up at once, especially the lowest ones (tub, shower)
- Toilets gurgle when the washer drains
- Sewage smell outside near the cleanout, or a patch of yard that stays wet or unusually green
- You have had the main line snaked more than once in a year
- Water comes up out of the cleanout

What breaks sewer lines around Phoenix
Roots
After grease, roots are the City of Phoenix's number two cause of sewer blockages; it specifically names oleanders and advises against planting trees or large shrubs over or near the sewer line or cleanout (Phoenix Water Services).
Aging pipe
About 40% of Phoenix housing was built before 1980 (Census ACS 2024). Cast iron from that era corrodes from the inside; Orangeburg fiber pipe, used in older parts of Phoenix, softens and flattens (KTAR).
Ground movement
Expansive and collapsing soils are common across Arizona and can rupture pipelines as they wet and dry (Arizona Geological Survey). Caliche, the cemented calcium carbonate layer common in Valley soils, can make digging slow and add to excavation cost (University of Arizona Extension).
Grease and wipes
Cooking grease hardens in the line; "flushable" wipes do not break down like toilet paper.
Cast iron under a slab: repair, reline or reroute
Most Phoenix homes sit on a concrete slab, so the first stretch of drain often runs under the floor. When cast iron under the slab cracks or scales shut, there are three honest options: break the floor and replace the bad section, line the pipe from the cleanout without opening the floor, or abandon the old run and reroute a new line around the house. Lining avoids jackhammering tile and cabinets, but the pipe must be descaled and still round. Rerouting can make sense when the line under the slab is failing along its whole length.
Ask the contractor to mark on the camera report where the slab section starts and ends. It changes the price more than almost anything else.
Who pays: you, the City or a warranty plan
In Phoenix, owners maintain the line from the house to the city main, but the City repairs a broken section inside the public right-of-way for single-family homes and duplexes (City Code 28-5). A camera locate shows where the break is, which decides who pays.
Optional warranty plans exist: the City of Phoenix partners with American Water Resources for water and sewer line protection (City of Phoenix). Read the exclusions. In 2025 a Tempe homeowner paid $11,000 after a warranty company called tree root damage pre-existing (azfamily).
Sewer Line Repair: common questions
How do I know if my sewer line is broken or just clogged?
A clog clears and stays clear. If the main line backs up again within months, or the camera shows cracks, offsets or roots through a joint, the pipe is damaged.
Do I need a permit for sewer line repair?
Clearing and cleaning do not. Replacing a sewer line generally needs a plumbing permit and inspection; Tempe and Glendale state it outright. Your licensed contractor should pull it and include it in the quote.
Can sewer repair be done without digging?
Often, using a spot liner or full CIPP liner through the cleanout. Collapsed pipe and deep bellies usually need at least a small excavation.
Is the sewer line under my yard the City's responsibility?
In Phoenix, the line on your property is yours to maintain. The City handles single-family laterals only where the broken section is inside the public right-of-way.
