Commercial Water Jetting for Restaurants, Multi-Unit, and Facilities
Water jetting, also called hydro jetting, cleans a drain or sewer line with high pressure water rather than punching through the blockage. For a commercial property that difference decides whether the line stays open through a full service cycle. Drain Detectives jets grease lines, kitchen branch lines, interceptor discharge lines, shared stacks, and mains for businesses and property managers across Macomb, Oakland, Wayne, and southern St. Clair County, from our Fraser, Michigan shop.

Line down during service hours? Call the county line directly. Commercial backups get triaged on the impact to your operation, not just the size of the clog.

Fats, oils, and grease leave a commercial kitchen warm and liquid. They travel a few feet, cool against the pipe wall, and set. Every service adds another layer. Nothing about the process is dramatic, which is exactly why it goes unnoticed until the line is most of the way closed.
By the time a commercial drain is visibly slow, the effective diameter of that pipe has usually been shrinking for months or years. The clog is not the event. It is the deadline.
-
It builds where you cannot see it
Long horizontal runs, the base of a stack, and the stretch between the kitchen and the interceptor collect the most. None of those are visible from inside the building.
-
Cabling makes it look solved
A cable bores an opening through the grease and flow returns, which reads as a fix. The pipe wall is still coated, so the opening closes again on the same schedule it closed the first time.
-
It fails at the worst possible hour
Lines back up under peak load, because peak load is when the volume is highest. That means dinner service, a full building, or a holiday weekend.
-
The cost is rarely the plumbing bill
It is the closed dining room, the tenant complaints, the health inspection conversation, and the emergency rate for after-hours response.
What We Jet, and How Often It Usually Needs It
| Property type | Lines that fail first | What builds up | Typical starting interval |
|---|---|---|---|
| Full-service restaurant | Kitchen branch lines, interceptor discharge line, main | Fats, oils, grease, food solids | Quarterly, more often at high volume |
| Fast food and quick service | Floor drains, kitchen branch, grease line | Heavy fryer grease, solids | Quarterly |
| Apartments and condos | Shared stacks, main, laundry lines | Grease, soap scum, hair, wipes | Annually, or semi-annually with history |
| Office and retail | Break room lines, floor drains, long horizontal runs | Food waste, soap, sediment | Annually or as needed |
| Schools, churches, banquet | Commercial kitchen lines used in bursts | Grease that sits between heavy-use events | Ahead of the busy season |
| Medical and salon | Branch lines, floor drains | Solids, product residue, hair | Annually or as needed |
Grease Interceptors: What Jetting Does and Does Not Cover
These two services get conflated in quotes, and the difference matters when you are budgeting or answering an inspector.
- Pumping the interceptor means removing the accumulated grease and solids from the tank itself. That is a waste hauling service performed by a licensed pumper on a schedule your municipality may require you to document.
- Jetting the lines means cleaning the pipe running into and out of that interceptor, plus the kitchen branch lines feeding it. Grease coats those runs regardless of how recently the tank was pumped.
A pumped interceptor with a coated discharge line still backs up. If your interceptor is on a service schedule and you are still seeing slow drains, the lines are where to look next. Many Metro Detroit municipalities require grease interceptor maintenance records, so confirm your local requirement with your city, since it varies.
Scheduling Around Your Operation
-
Walk the property and inspect
We locate cleanouts, identify which lines carry what, and camera the problem runs. On a building nobody has documented, this pass alone usually explains the recurring call.
-
Jet on your clock, not ours
Where the job allows it, we work outside your service hours so the kitchen or the building stays open. We already run 24 hours, so off-peak scheduling is not a special request.
-
Set an interval and stop guessing
Once we know what the line does, we recommend a frequency that gets ahead of it. Planned maintenance is priced and scheduled. Emergencies are neither.
Why property managers move to a schedule
An emergency call is the most expensive way to buy the same service. It arrives at an after-hours rate, on someone else's timeline, with the building or the kitchen already down and tenants or customers already affected. Scheduled jetting converts an unpredictable operating risk into a line item you control.
When We Will Tell You Not to Jet
Jetting cleans pipe. It does not fix pipe. On a commercial building the distinction is worth real money, so we inspect before recommending it.
-
The camera shows structural failure
Collapsed, offset, or bellied sections need repair. Jetting a broken line produces a clean broken line and a repeat call.
-
The pipe material will not take it
Severely corroded cast iron and Orangeburg pipe are the two we flag. Older commercial buildings in this area have both.
-
Established root intrusion
Fine root hair clears with a cutting nozzle. Woody roots that have widened a joint need mechanical cutting or a repair to that joint.
-
The real problem is upstream
Sometimes the line is fine and the practice is not. If the fix is a strainer, a staff habit, or an interceptor on the wrong schedule, we will say so rather than sell you a quarterly.

Commercial Water Jetting FAQ
Is water jetting the same as hydro jetting?
Yes. Water jetting, hydro jetting, and sewer jetting all describe cleaning a line with high pressure water that removes buildup from the pipe wall. This page covers commercial and multi-unit properties. For a single family home, see hydro jetting for homes.
Can you work outside our business hours?
Where the job allows it, yes. We already operate 24 hours a day, so scheduling a kitchen line overnight or a shared stack before tenants are up is a normal request rather than a special accommodation. Tell us your service window when you request the quote.
Do you jet grease interceptor lines, or pump the interceptor?
We jet the lines running into and out of the interceptor, plus the kitchen branch lines feeding it. Pumping the tank itself is a waste hauling service handled by a licensed pumper. Both matter, and a recently pumped tank does not help if the discharge line is coated.
Are you licensed and insured, and can you provide a certificate?
Drain Detectives is a licensed, bonded, and insured plumbing company. We can provide a certificate of insurance for your property file on request. Michigan plumbing licenses are issued through LARA and you can verify ours through the state's free license verification tool.
Do you handle multiple properties under one account?
Yes. If you manage several buildings or locations across our service area we can coordinate scheduling across them rather than treating each address as a separate cold call.
How often should a commercial kitchen line be jetted?
Quarterly is a common starting point for a full-service kitchen, and high volume operations often need it more frequently. Rather than defaulting to a number, we camera the line, look at your actual clog history, and set an interval that gets ahead of the failure.
Will jetting damage older commercial pipe?
In sound pipe, no. Pressure and nozzle are matched to the line. The risk sits in pipe that is already compromised, which is why we camera older buildings first. Severely corroded cast iron and Orangeburg are the two materials we will tell you not to jet, and both turn up in older Metro Detroit commercial stock.
Do you provide documentation of the work?
Yes. Where we run a camera we can share what the line looked like before and after, which is useful for your maintenance file, for budgeting a future repair, and for conversations with ownership or an inspector.
What does commercial jetting cost?
Cost depends on line length and diameter, cleanout access, buildup severity, how many lines are in scope, and whether the work is scheduled or after-hours emergency response. We charge a service call fee to come out, diagnose the problem, and quote it. That fee is applied to the work if you go ahead, and you approve the price before anything starts. Scheduled maintenance is consistently cheaper per visit than emergency calls.
