Common Causes of Sewer Backups in Commercial Properties in Maricopa County
Backups are disruptive, unsanitary, and expensive. In Maricopa County, commercial properties face unique stressors that increase the risk of sewer overflows. Heavy grease loads from kitchens, long lateral runs under parking lots, and aging materials combine with seasonal monsoon events to challenge drainage systems. Our experienced plumbers use sewer video inspection and flow testing to identify root causes and recommend reliable sewer overflow prevention strategies tailored to your site in Gilbert, AZ.
Backups often result from:
- Grease and debris accumulation
- Root intrusion
- Surcharge from municipal mains
- Undersized lines
- Back-pitched pipes
- Heavy storm events
Even well-maintained facilities can experience surcharging when city mains are overwhelmed during storms, pushing wastewater toward low fixtures like floor drains and basements. Older properties in areas like the Heritage District or The Islands may also have improper slope or undersized laterals that cannot handle peak flows. We diagnose each factor and present options ranging from targeted cleaning to permanent plumbing backup systems.
How we pinpoint the problem
We combine camera inspections, locating equipment, and line-by-line capacity checks to map restrictions, bellies, and cross-connections. This data drives the right fix, whether it is scheduled hydro-jetting, a root management program, or a commercial backwater valve installation to block reverse flow.
