Ready for Reliable Commercial Plumbing?
Our commercial plumbing team is ready to keep your business running smoothly.
Restaurants and food service establishments have some of the most demanding plumbing requirements of any commercial property. High-volume kitchens generate enormous amounts of grease, food waste, and wastewater that can overwhelm standard plumbing systems. Duluth Plumbing Co specializes in restaurant plumbing services including grease trap installation, sizing, and maintenance; commercial garbage disposal systems; three-compartment sink installation to meet health code requirements; floor drain maintenance and cleaning; and hot water system design to meet the high-volume demands of a commercial kitchen.
Grease trap compliance is one of the most critical plumbing issues for food service operators in Duluth. Local regulations require grease traps or interceptors to prevent fats, oils, and grease from entering the municipal sewer system. An undersized, poorly maintained, or malfunctioning grease trap can result in code violations, fines, and sewer backups that force you to close your doors. We install properly sized grease traps for new restaurants and provide scheduled maintenance services to keep existing systems compliant and functional. Our maintenance program includes pumping, cleaning, and inspection on a schedule that meets regulatory requirements and prevents problems before they occur.
Commercial dishwashers, ice machines, and beverage systems all require proper plumbing connections with backflow prevention. We install and maintain these connections to ensure they meet health codes and operate reliably. When equipment breaks down, our fast response time helps minimize disruption to your business operations.

Office buildings, retail stores, and mixed-use commercial properties have unique plumbing needs that differ significantly from residential systems. Higher occupancy means more demand on restroom fixtures, water supply systems, and drain lines. Duluth Plumbing Co provides comprehensive plumbing services for commercial offices and retail spaces including restroom fixture installation and repair, water fountain and bottle filler installation, break room plumbing, tenant improvement build-outs, and ADA-compliant fixture upgrades.
For property managers overseeing multiple commercial units, we offer maintenance contracts that provide priority scheduling, reduced rates, and regular preventive inspections. Proactive maintenance catches small problems before they become expensive emergencies. A leaking pipe in a commercial building can damage inventory, equipment, and tenant improvements, and may expose the property owner to liability claims. Regular inspections of supply lines, drain systems, water heaters, and shut-off valves help prevent these costly scenarios.
Tenant improvement projects often require plumbing modifications — adding restrooms, relocating sinks, installing new water supply and drain lines for specific business needs. Our commercial team works efficiently within occupied buildings, coordinating with other trades and minimizing disruption to existing tenants.
Multi-Unit Properties
Multi-Unit Residential and HOA Plumbing
Apartment complexes, condominium buildings, and homeowner associations face plumbing challenges that require a plumber experienced with shared systems. A plumbing problem in one unit can affect neighboring units, common areas, and building infrastructure. Duluth Plumbing Co has extensive experience with multi-unit properties and understands the urgency of resolving issues quickly to prevent cascading damage and tenant complaints.
Common multi-unit plumbing services we provide include shared sewer line maintenance and cleaning, individual unit repairs and fixture replacements, main water line and riser pipe maintenance, water heater replacement in utility rooms and individual units, backflow prevention device installation and annual testing, and emergency response for leaks and flooding that affect multiple units. We work directly with property managers, HOA boards, and building maintenance staff to develop maintenance schedules and emergency response plans tailored to each property's needs.
For large multi-unit properties, we offer annual plumbing assessments that evaluate the condition of the entire building's plumbing infrastructure. This includes inspecting main supply lines, shared drain and sewer lines, water heaters, shut-off valves, and common area fixtures. The assessment report identifies current issues and prioritizes recommended repairs, helping property managers budget effectively for plumbing maintenance and capital improvements.
Need Commercial Plumbing Maintenance?
Keep your property running smoothly with proactive plumbing maintenance from our experienced commercial team.
Backflow prevention devices are required on most commercial properties in Duluth to protect the public water supply from contamination. These devices prevent water from flowing backward through the plumbing system, which could introduce pollutants, chemicals, or bacteria into the municipal water supply. Local water authorities require annual testing and certification of backflow prevention devices by a certified tester.
Duluth Plumbing Co employs certified backflow prevention testers who can install new devices, perform required annual testing, make repairs to failed devices, and submit certification paperwork to the local water authority on your behalf. We maintain testing records and send reminders when your annual test is due, ensuring you stay in compliance and avoid penalties. Failing to maintain required backflow prevention can result in fines and potential water service disconnection.
Emergency Service
24/7 Commercial Emergency Plumbing
A plumbing emergency in a commercial property can halt business operations, damage inventory and equipment, create safety hazards for employees and customers, and expose you to liability. Duluth Plumbing Co provides true 24/7 emergency plumbing service for commercial properties throughout Duluth and surrounding areas. When you call our commercial emergency line, we dispatch an experienced commercial plumber immediately.
Our commercial emergency trucks carry the parts, tools, and equipment needed to handle most emergency repairs on the spot. Common commercial plumbing emergencies include burst pipes and major leaks, sewer line backups, gas line leaks, water heater failures, flooding from any source, and broken main shut-off valves. We provide temporary solutions when needed to get your business operational quickly, then schedule a permanent repair at a time that minimizes disruption. Every commercial emergency call includes a detailed report documenting the problem, the repair performed, and any recommendations for preventing recurrence.
Preventive Programs
Commercial Preventive Maintenance Programs
The most cost-effective approach to commercial plumbing is preventing problems before they occur. Duluth Plumbing Co offers customized preventive maintenance programs for commercial properties of all types and sizes. Our maintenance programs include scheduled drain cleaning and inspection, water heater flushing and maintenance, fixture inspection and repair, shut-off valve testing, backflow device testing, and seasonal preparation. Each program is tailored to the property's specific systems, usage patterns, and regulatory requirements.
Preventive maintenance typically costs a fraction of emergency repairs and significantly extends the lifespan of your plumbing infrastructure. Our commercial clients consistently report fewer emergency calls, lower repair costs, and better tenant satisfaction after implementing a maintenance program. Contact us to discuss a maintenance plan designed for your property's needs and budget.
New Construction
Commercial New Construction and Tenant Build-Out Plumbing
Whether you are building a new commercial property from the ground up or renovating an existing space for a new tenant, Duluth Plumbing Co provides expert commercial plumbing design and installation services. We work with general contractors, architects, and property owners throughout the Duluth area to deliver plumbing systems that meet code requirements, support the intended use of the space, and are built for long-term reliability.
Our commercial new construction services include plumbing system design and layout, rough-in plumbing for new buildings, fixture selection and installation, water heater and boiler system installation, gas line installation for kitchens and heating systems, fire sprinkler tie-ins and coordination with fire protection contractors, and final inspection coordination with local building officials. For tenant build-outs, we specialize in adapting existing plumbing infrastructure to meet new tenant requirements — adding restrooms, relocating kitchen facilities, installing specialized equipment connections, and ensuring all modifications comply with current building codes and ADA requirements.
Our commercial plumbers are experienced with the specific code requirements, permitting processes, and inspection standards in Duluth and throughout Minnesota. We pull all necessary permits, schedule required inspections, and ensure every installation passes on the first inspection. This saves time and avoids costly delays on your construction timeline.
