Drain Backing Up When Laundry Runs - Arizona Main Line Guide
Why This Happens
Your washing machine dumps 15–30 gallons rapidly. If the main line is partially clogged, it forces water into:
tubs
showers
toilets
floor drains

Causes
Main line clog
Root intrusion
Grease buildup
Collapsed pipe
Improper slope
Vent blockage
Arizona - Specific Causes
Clay sewer pipes in older AZ homes crack easily. Desert trees (mesquite, palo verde) aggressively invade sewer lines.
Fixes
Camera inspection
Hydro-Jetting
Root removal
Pipe repair
