When a drain backs up in a restaurant during the dinner rush, or a water heater fails in an office building on a Monday morning, Denver businesses need a commercial plumber who shows up the same day and knows what they’re doing. CO-PI Plumbing and Drain provides commercial plumbing services to businesses, property managers, and general contractors across Denver and the surrounding metro. We handle everything from drain cleaning and sewer repair to backflow testing, hydro jetting, new construction, and tenant improvement work.
If you manage a property or run a business in Denver and need a licensed commercial plumber, call us at (720) 930-7125 or request service online.
Everything will be okay, we are here to help!
Grease buildup, debris, and root intrusion are the most common causes of commercial drain failures in Denver. We clear main lines and secondary lines for restaurants, office buildings, retail spaces, and multi-unit properties. For heavy buildup and recurring blockages, high-pressure hydro jetting removes everything from the pipe wall rather than just punching through the clog. For restaurant and commercial kitchen drain systems specifically, our commercial drain cleaning services are built around the higher demands those lines see daily.
Sewer line problems in commercial properties don’t fix themselves and the longer they go, the worse the disruption gets. We diagnose, repair, and replace commercial sewer lines across Denver, with sewer camera inspection available to identify the exact issue before any excavation begins. For full line failures, our commercial sewer line repair team handles the excavation, repair, and site restoration.
High-demand water heater systems in restaurants, hotels, gyms, and multi-unit buildings have different requirements than residential units. We install, repair, and replace commercial water heaters through our commercial water heater services, including Ultra-Low NOx-compliant systems required under Colorado’s 2026 regulations, and we carry Bradford White and Rinnai-certified inventory.
Commercial gas line work requires proper permitting, code compliance, and coordination with the city and utility. We handle gas line installation and repair for Denver businesses and manage the permit process from start to finish. Full details on scope and process are on our commercial gas line services page.
Before any repair, excavation, or construction work, knowing exactly what’s in the ground saves time and money. Our sewer inspection and camera locating services give contractors and property managers accurate information before the work begins, and we can locate and mark underground lines for construction coordination.
CO-PI works with general contractors on core and shell builds, tenant finish projects, and commercial remodels across the Denver metro. We coordinate with inspectors, pull permits, and meet construction timelines. More on how we approach these projects is on our new construction plumbing page.
Most commercial plumbing problems don’t happen at convenient times. A grease trap backs up on a Friday night. A water heater fails the week before a restaurant opens. A backflow device fails its annual test and the water district sends a notice. CO-PI responds quickly, communicates clearly about what we find and what it costs, and gets the work done without creating a second problem.
We are a family-owned, licensed commercial plumbing company serving Denver and the Front Range. We work regularly with property managers overseeing office and retail portfolios, restaurant operators managing high-use drain systems, and general contractors who need a plumbing subcontractor that shows up on schedule and passes inspection.
A few specifics worth knowing:
CO-PI is Bradford White and Rinnai certified, which matters for commercial water heater installations and warranty coverage. We are fully licensed and insured in Colorado. We handle permitting and inspection coordination so you don’t have to track it separately. And we do not subcontract work out, so the team you talk to on the phone is the team that shows up.
