Commercial Plumbing in Mukilteo, WA
Commercially licensed plumbers based in Old Town, for Mukilteo's restaurants, building owners and property managers
Stollwerck Plumbing & Sewer is the commercial plumber that is already in Mukilteo. Our shop sits on 5th Street in Old Town, so a restaurant with a backed-up floor drain or a property manager with a sewer break gets a commercially licensed plumber without a drive from another city, and usually the same day.
Real Commercial Work in Mukilteo
In June 2026 a restaurant in Old Town Mukilteo called about a drain that would not stay clear. A kitchen line that clogs once is a cleaning job, but one that keeps coming back usually means the pipe itself has a problem, and camera and locating work put the trouble outside the building, in the side sewer between the kitchen and the street. Logan took the job from there.
The first step was to get the utility locate called in and marked, because nothing gets dug on a commercial lot until every line under it is painted. Then he excavated down to the located break, cut into the concrete at the failure, and ran the trailer-mounted jetter through the opening at 4,000 psi and nine gallons a minute to scour the line downstream. The line took the water, which was good news for the kitchen. The camera that followed the jetter was less encouraging: the bottom of the pipe was simply gone for as far as the lens could see, so the sewer had been running on the dirt beneath it. That is not something a clog call fixes, and Logan said so plainly.
What he could do that day was make the line serviceable. He installed a proper side sewer cleanout at the excavation, so the next jetting or camera pass happens from the surface instead of through the kitchen, and laid out the next stage: chase the pipe at least another three feet, with more jetting and camera work to find where sound pipe begins. The restaurant kept operating, the owner had a clear picture of what was under the ground and what came next, and the repair moved forward in stages rather than arriving as one surprise.
Who We Work For in Mukilteo
Restaurants and Bars
Old Town and the waterfront run on kitchens, and kitchens run on drains. We clear floor sinks behind bars, dish-pit lines and grease-side drains, and we know the district’s grease rules well enough to tell you what the log needs to show. One Mukilteo taproom has had us back to the same floor sink behind the taps twice in five months, which is exactly the kind of recurring call a maintenance visit prevents.
Building Owners and Their Property Managers
The restaurant job above was billed to the company that owns the building rather than to the kitchen, and that is common. We work from the owner’s or manager’s work order, keep the tenant informed on site, and document what we found so the people paying for the repair can see it without driving over.
Schools and Care Facilities
A private school in Mukilteo called us about a leaking restroom sink drain. Logan and Carlos replaced the pop-up assembly, re-set a sink that had worked loose from its counter, and confirmed that a reported urinal leak was not a plumbing leak at all. Care-facility kitchens get the same care, scheduled around meal service so the dish pit is back before it is needed.
Contractors and Tenant Improvements
J.D. came up through commercial construction, and the company still takes plumbing scopes for contractors fitting out Mukilteo commercial space, from gas-line calls to new fixture sets, with the licensing and insurance a general contractor’s paperwork requires.
Mukilteo-Specific Considerations
The Water District Runs the Grease Program
In Mukilteo, sewer service and the rules that come with it belong to the Mukilteo Water & Wastewater District rather than to city hall. The district runs an Industrial Pretreatment Program for the businesses on its sewer, and for a kitchen that means a Grease Trap / Interceptor Operation and Maintenance Log posted at the trap and turned in to the district’s pretreatment staff, with the program’s costs recovered through fees and surcharges. We keep our drain-side work consistent with what that log expects, so an inspection does not turn up a gap.
Old Town Buildings Without a Cleanout
Many of the commercial buildings on the Old Town grid started life as houses or storefronts decades before anyone expected a jetter to visit, and a surprising number have no exterior cleanout. That means every drain problem starts with a trip through the kitchen. When we have a line open for a repair, as on the restaurant job above, we add a cleanout so the next visit is faster and cheaper for everyone.
The Shop Is Already in Town
Our office is on 5th Street in Old Town, minutes from the ferry terminal, the Speedway corridor and Harbour Pointe. For a business that shows up as shorter waits on emergency calls and an easy return visit when a repair runs in stages. Ferry traffic on the Speedway can slow an arrival at peak times, and we plan around it rather than pretending it is not there.
Commercial Plumbing FAQ for Mukilteo
Who sets grease-interceptor rules for Mukilteo restaurants, and what do they expect?
The Mukilteo Water & Wastewater District sets the rules through its Industrial Pretreatment Program. Food-service businesses on the district’s sewer keep the district’s grease trap and interceptor maintenance log posted at the trap, record each cleaning or pumping, and submit the log to the district’s pretreatment staff, who recover the program’s costs through fees and surcharges.
We are not the district’s inspector, but we work the drain side of that system every week, and when what comes back on the cable points to a trap that is overdue, we say so before the district does.
Can you add a cleanout to a commercial side sewer in Mukilteo?
Yes. A side sewer cleanout is a capped access fitting installed on the line outside the building, and we add one whenever we have a line open for repair or when a business keeps needing service through the kitchen. On the Old Town restaurant job above, the cleanout went in the same day as the jetting and camera work.
Who pays when a restaurant’s sewer line breaks, the tenant or the building owner?
That depends on the lease, not on us. In many commercial leases the building’s drain and sewer lines fall to the owner and the fixtures to the tenant, but the split varies. We work for whoever holds the work order, keep the other party informed on site, and have billed sewer repairs to owners and drain clearing to tenants.
Do you handle the utility locate before a commercial dig in Mukilteo?
Yes. Before any excavation on a commercial lot we call in the utility locate so that gas, power, water and communication lines are marked, and we do not break ground until the marks are down. The restaurant sewer repair above was located before the digging started, and the same rule applies to every trench we open.
How quickly can you reach a business in Old Town or Harbour Pointe?
Usually the same day, because our shop is on 5th Street in Old Town and Harbour Pointe is a few minutes down the Speedway. We are open Monday through Friday, and the one thing that slows an arrival is ferry traffic at peak times, so we give you an honest window when you call rather than a hopeful one.
