Drain & Sewer Services in Modesto, CA
Modesto’s tree-lined streets are one of its best features. For your sewer line, they’re a constant threat. Root intrusion is one of the top reasons Modesto homeowners call us for sewer service. And it’s one of the most misdiagnosed problems in plumbing. Knights Plumbing & Drain has been serving Stanislaus County since 1995, and we know the difference between a drain that needs cleaning and a sewer line that needs repair.
Call (209) 319-0546 for a drain or sewer inspection today.

The Modesto Drain & Sewer Reality
Homes in Bret Harte, Sunnyside, and the College Area were built before 1970, and many still have original clay or cast iron sewer laterals. Hard Central Valley water accelerates scale buildup. Modesto’s mature tree canopy means roots are always probing for the nearest moisture source. These aren’t hypothetical problems; they’re what our plumbing technicians find on camera inspections every week in Modesto neighborhoods.
