What We Handle for Modesto Businesses
Drain Cleaning and Hydro-Jetting
Commercial facilities put far greater demand on drain systems than residential properties. Restaurant grease lines, floor drains in food service and industrial facilities, and high-use restroom main lines require professional clearing on a regular basis. Our hydro-jetting equipment clears commercial drain lines completely not temporarily.
Commercial Water Heater Service
High-volume hot water demand in commercial settings requires properly sized, professionally maintained equipment. We install and service commercial tank and tankless water heaters for Modesto restaurants, laundromats, salons, medical facilities, and property managers across Stanislaus County.
Gas Line Work
We offer licensed, permit-pulled gas line services for commercial properties, including new appliance connections, leak detection and repair, line extensions, and code-compliant installations. Modesto’s commercial food service sector depends on reliable gas infrastructure; Knights Plumbing has the licensing and experience to maintain it.
Backflow Prevention and Certification
Stanislaus County requires current backflow preventer certifications for commercial properties with irrigation systems, fire suppression, or commercial kitchen connections. We perform the testing and provides the required documentation to keep your property in compliance.
Leak Detection and Repair
Commercial property leaks often go undetected in walls, ceilings, and under slabs which run up water costs and damage building infrastructure before the problem becomes visible. We use advanced detection equipment to find leaks with minimal disruption to your facility.
24-Hour Emergency Response
A plumbing failure during business hours is a revenue emergency. Knights Plumbing & Drain responds to commercial calls in Modesto with the same urgency as residential emergencies. Our fully stocked trucks mean most plumbing services are completed in a single visit.
