Commercial plumbing for restaurants, retail, offices, and multi-unit buildings — grease interceptors, commercial water heaters, backflow assemblies, ADA fixtures, and code compliance. Scheduled around your operating hours to minimize downtime.
Commercial Plumbing is one part of our plumbing installation coverage in Michigan. For the full picture — symptoms, costs, and when to repair vs. replace — start with the complete Plumbing Installation guide, or browse every plumbing installation service we offer.
Commercial plumbing runs harder and under more code scrutiny than any home system — a restaurant's grease line, a multi-unit building's risers, an office's ADA fixtures, and the backflow assembly that protects the potable supply all carry consequences if they fail: health-code citations, tenant complaints, and downtime that costs real revenue. We service and maintain commercial systems for restaurants, retail, offices, medical, and multi-unit properties, and we schedule the work around your hours so a repair doesn't shut the business during service.
The commercial-specific systems are where experience matters. Grease interceptors and traps have to be sized, pumped, and maintained to health-department standards or the kitchen fails inspection; commercial water heaters and recirculation loops have to deliver hot water on demand to fixtures that never stop; and backflow assemblies protecting the Michigan potable supply require annual certified testing that we perform and file. We also handle the high-volume basics — trap-primed floor drains, ADA-compliant fixtures, tankless banks, and the main-line jetting that keeps a busy kitchen from backing up mid-shift.
For a commercial property, plumbing is operational risk, and the cheapest version of that risk is a maintenance schedule instead of an emergency. A grease line that clogs during dinner, a backflow assembly that fails its annual test, or a water heater that quits before opening costs far more in lost hours and citations than the scheduled visit that would have caught it. We build jetting, backflow testing, and water-heater service into a plan for your Michigan property, respond fast when something does fail, and price larger projects as a clear scoped quote.
A kitchen line that backs up during service is losing you revenue and risking a health citation. Scheduled jetting on a Michigan grease line keeps it clear instead of failing mid-shift.
Backflow test is due or overdue
Most jurisdictions require annual certified backflow testing, and a lapsed test can mean fines or a shut-off notice. We test, certify, and file with the Michigan water authority.
Hot water can't keep up
A commercial water heater that runs out during peak use is undersized or failing. Right-sizing the heater or recirculation loop restores capacity for a busy Michigan business.
Planning a build-out or expansion
Adding seats, restrooms, or equipment changes the plumbing load and the code requirements. We spec the rough-in and capacity before the Michigan build-out starts.
Aging building with deferred issues
Older commercial buildings accumulate corroded risers, tired water heaters, and outdated fixtures. A system assessment turns a pile of surprises into a planned Michigan maintenance budget.
Root causes we repair with commercial plumbing
Grease and high-volume buildup
Commercial kitchens push far more grease and food waste through their lines than any home, coating and clogging them fast. Regular interceptor pumping and line jetting is the only thing that keeps a Michigan kitchen open.
High-use fixture wear
Restrooms and kitchens in a busy building cycle fixtures hundreds of times a day, wearing valves, flushometers, and faucets quickly. Commercial-grade parts and scheduled service keep them running.
Deferred maintenance
Commercial systems that only get attention when they fail accumulate risk across the whole building. A maintenance plan trades emergency downtime for scheduled Michigan visits.
Code and compliance changes
Backflow, grease, ADA, and water-efficiency codes tighten over time, and non-compliance carries fines. We bring Michigan systems up to current requirements as part of service.
Undersized or original systems
Buildings repurposed or expanded past their original plumbing capacity starve fixtures and overwork heaters. Correcting the sizing is often the root fix for a Michigan property's recurring problems.
