Commercial plumbing in Oakland County covers six core services: drain and sewer cleaning, hydro jetting, sewer camera inspection, pipe lining, backflow testing, and repair and emergency response. Costs depend on the property type and pipe size. Bison Plumbing quotes commercial hydro jetting and other commercial work by scope after a camera inspection. The right contractor is licensed in Michigan, diagnoses with a camera before recommending anything, documents the work, and prioritizes active drain backups during business hours.
What Commercial Plumbing Actually Covers
Commercial systems are larger and busier than residential ones: bigger-diameter lines, heavier use, and a business that loses money while a drain is down. Bison’s commercial plumbing services support apartment and condo complexes, office buildings, restaurants and hospitality venues, retail centers, schools, medical facilities, and industrial plants. Here is how the main services break down.
| Service | What It Does | When a Business Needs It |
| Drain and sewer cleaning | Clears blockages in floor drains, branch lines, and main laterals | Slow drains, recurring backups, tenant complaints |
| Commercial hydro jetting | High-pressure water scours grease, scale, and debris from large-diameter lines | Restaurant kitchens, multi-tenant buildings, scheduled maintenance |
| Sewer camera inspection | Shows the pipe’s actual condition and documents it on video | Before any repair decision, after jetting, and for compliance records |
| Pipe lining (CIPP) and patching | Rehabilitates a damaged sewer line from the inside, without a trench | Cracked, root-infiltrated, or deteriorating lines under pavement or landscaping |
| Backflow testing | Tests and certifies the assemblies that protect the public water supply | Whenever your water supplier requests it, typically annually for commercial devices |
| Repairs and emergency response | Fixes leaks, backups, and failures, with after-hours dispatch for emergencies | Active backups or failures that can’t wait for a standard appointment |
Drain Cleaning and Commercial Hydro Jetting
Grease is the main cause of commercial drain trouble, and snaking alone rarely clears it for long. Commercial hydro jetting runs at 4,000 to 5,000+ PSI on 4 to 12 inch lines, versus 1,500 to 3,500 PSI for residential jetting, and Bison pairs it with a camera before and after so the result is documented. How often you need it depends on what your kitchen or building produces:
| Property Type | Typical Jetting Schedule |
| Full-service restaurants and high-volume kitchens | Quarterly (every 3 months) |
| Offices, cafes, low-volume food service, hotels and event venues | Biannual (every 6 months) |
| Light commercial, retail without food tenants, industrial floor drains | Annual |
Sewer Camera Inspection: Look Before You Repair
A sewer camera inspection is the step that keeps a commercial repair honest. It shows whether you have a grease buildup that jetting will clear, or a cracked or collapsed section that jetting would only aggravate. Bison’s own commercial jetting page puts it plainly: if the camera shows a collapse rather than accumulation, the recommendation changes, because jetting a failed lateral makes the shutdown longer, not shorter.
Pipe Lining for Damaged Sewer Lines
When the pipe itself is the problem, CIPP pipe lining rehabilitates the line from the inside without opening a trench through landscaping or hardscape. Bison states its lining work complies with ASTM F1216 and ASTM F1743, the national standards for cured-in-place pipe. For a commercial property, that matters most when the failing line runs under a parking lot, sidewalk, or finished landscaping, where excavation means closing part of the site.
Backflow Testing: A Compliance Item, Not an Optional One
If your building has testable backflow assemblies, your water supplier will eventually ask for test results. Michigan’s cross connection rules, administered through EGLE’s Cross Connection Control program, prohibit cross connections and require every public water supply to run a program of inspections, testing, recordkeeping, and education. A business with a testable device can expect a letter requesting a test by a professional tester with ASSE 5110 certification, and EGLE notes that the cost of installation and testing is often paid by the water customer. Bison’s backflow testing recommends annual testing for most commercial devices, and local programs can set their own schedules, so check your supplier’s letter for the interval that applies to you.
What Commercial Plumbing Costs in Oakland County
Bison publishes starting prices for commercial jetting and inspection, which makes budgeting a recurring service straightforward. Everything else is quoted after a camera inspection, because pipe size, access, and condition drive the price more than the type of building.
| Service | Published Price Range | What’s Included |
| Restaurant or commercial kitchen jetting | Quoted after camera inspection | Floor drains, branch lines, and main lateral; quarterly scheduling recommended |
| Office building drain jetting | Quoted after camera inspection | Floor drains, restroom laterals, and break room lines; multi-floor buildings quoted by scope |
| Large-diameter main line jetting (4–12 inch) | Quoted after camera inspection | Industrial, multi-tenant, and corporate campus laterals |
| Emergency commercial jetting | Quoted after camera inspection | Priority scheduling for an active backup during business hours, with food service first in line |
| Standalone sewer camera inspection | $135 | Diagnostic inspection when no other work is booked |
| Recurring service contract | Reduced per-visit rate | Quarterly, biannual, or annual schedule; quoted individually |
Why a recurring schedule usually costs less per visit: Bison prices quarterly, biannual, and annual contracts at a reduced per-visit rate compared with one-off calls, and a scheduled visit costs far less than an emergency call during service hours. For a kitchen where a backup means lost covers, the schedule is the cheaper option.
What Drives the Final Number
- Pipe diameter and run length: a 6-inch main lateral takes more equipment and time than a floor drain branch.
- Access: interior cleanouts are quick; reaching a lateral from a yard or street access takes longer.
- Severity of buildup or damage: a missed year of grease takes more passes than a maintained line.
- Timing: scheduled off-hours work is priced differently than work during regular business hours.
How to Choose a Commercial Plumbing Contractor in Oakland County
- Verify the Michigan license: ask for the license number and check it through the state’s LARA license lookup before you sign.
- Ask who tests your backflow assemblies: the tester needs ASSE 5110 certification for your water supplier to accept the results.
- Expect a camera before a recommendation: a contractor who quotes a repair without looking inside the line is guessing.
- Ask for documentation: before-and-after footage and a service report give you a record for inspectors and for your own files.
- Confirm recurring and emergency options: you want one contractor who can both schedule maintenance and respond when something fails.
- Get the scope in writing: a written estimate that names the lines, the method, and what’s included prevents disputes later.

Frequently Asked Questions
How often should a restaurant have its drains jetted?
Bison recommends quarterly jetting for full-service restaurants and high-volume kitchens, and biannual for lower-volume food service. The interval should be set from your cooking volume and what the camera shows, not a generic calendar.
How much does commercial hydro jetting cost?
Bison quotes commercial hydro jetting after a camera inspection; the price depends on pipe diameter and line length, and recurring contracts are priced at a reduced per-visit rate.
Does my business need backflow testing?
If your property has a testable backflow assembly on a connection to the public water supply, your water supplier will typically send a letter requesting testing by an ASSE 5110 certified tester. Many commercial properties have separate domestic, fire protection, and irrigation connections, and each assembly is tested individually.
Can a damaged commercial sewer line be repaired without digging up the property?
Often, yes. CIPP lining rehabilitates a line from the inside when the pipe is damaged but still holds its shape. A camera inspection confirms whether lining is possible, because a collapsed section needs a different repair.
Commercial plumbing is mostly a maintenance business: the properties that run smoothly are the ones on a documented schedule, with a camera-confirmed baseline and a contractor who answers the phone when something goes wrong. Start with a camera inspection and a schedule that fits your property, and let the footage drive the rest of the decisions.
