Main Line Drain Cleaning in Phoenix, AZ
If all the drains in your Phoenix home are running slow, or if you hear gurgling from your shower when you flush a toilet, the problem is likely in your main sewer line. This large pipe carries all wastewater away from your home, and a clog here affects everything. We specialize in professional main line drain cleaning, using powerful equipment to break through and remove deep blockages.
Blockages in Your Main Line
The main sewer line can become blocked by several common factors:
- Tree Root Intrusion: Roots growing into pipe joints to seek water.
- Grease and Sludge: Years of buildup from kitchen drains narrowing the pipe.
- Foreign Objects: Things that shouldn't be flushed accumulating into a mass.

Warning Signs of a Clog
Don’t wait for a total backup. Call us if you notice these early warning signs:
Multiple Slow Drains: The problem is affecting your whole house, not just one sink.
Toilet Gurgling: Air being pushed back through the drains when you use the shower or washer.
Sewage Odor: Foul smells coming from utility areas or floor drains.

Powerful, Safe Main Line Cleaning
We use professional-grade drain augers that are strong enough to reach and cut through the toughest clogs. For chronic buildup, we often recommend a video inspection to confirm the cause, followed by hydro-jetting to completely scour the interior walls of the pipe for a long-lasting clean.
