Older Phoenix Sewer Lines
In west Phoenix neighborhoods built in the 1950s and 1960s, like much of Maryvale, sewer laterals were often clay or cast iron. Clay pipe comes in short sections joined every few feet, and after sixty years, roots have found many of those joints. Cast iron corrodes along the bottom and can crack or collapse.
Newer north Phoenix homes have PVC or ABS lines, where problems are more often from settling, damage or buildup.
Alex & Bros Plumbing serves west and north Phoenix from our base in Peoria. Alex does the work himself and explains what he finds.

Monsoon Season and Your Sewer Line
Phoenix monsoon storms bring heavy rain in short bursts. If your sewer line has cracks or open joints, rainwater and groundwater can seep in and overload the line. A line that barely keeps up on a normal day can back up during a storm.
If your drains slow down or back up during summer storms, the sewer line likely has openings that need repair. Getting it checked before monsoon season is a lot less stressful than dealing with a backup during one.

Repair and Replacement Options
- Clearing. We cut roots and clear buildup to restore flow.
- Diagnosis. We figure out where the damage is and what kind.
- Section repair. Excavate and replace a damaged section with PVC.
- Full replacement. Replace the whole lateral when there are multiple problems.
Some sewer replacements in Phoenix require a permit. We will let you know. For more detail on each option, see our main Peoria sewer line page. For simpler clogs, see drain cleaning in Phoenix.
Tree Roots in West Phoenix
Older west Phoenix neighborhoods often have mature trees in front yards, sometimes planted right over the sewer line decades ago. Ficus, mesquite, eucalyptus and palo verde all send roots toward water, and older clay pipe joints are an easy entry point.
Root intrusion usually starts slowly. A line that drains fine most of the time backs up during heavy use. Over months, the root mass grows until the line blocks.
Cutting roots restores flow. If the pipe is in good shape apart from one or two joints, a section repair at those joints is often the best long-term fix. If roots are in multiple places, full replacement usually costs less than repeated clearing. We will tell you what we see and recommend the least invasive fix that will actually hold up.

What Phoenix Homeowners Say
I was referred to Alex because the scope of work was beyond what my usual plumber could handle, and I couldn’t be happier with the recommendation.
S. Camilla Madison-Wilson
Alex arrived at our house on short notice. He did a great job and explained the cause (which I always appreciate) of the clogs, so I can hopefully prevent in future. Prompt and courteous. I recommend him and his brother.
