Commercial Plumbing in Lake Stevens, WA
Roof drains, restaurant kitchens and building plumbing for Lake Stevens businesses around Frontier Village and the west end of the lake, from a commercially licensed crew based in Mukilteo
Stollwerck Plumbing & Sewer is commercially licensed and insured above Washington’s minimums, and we work for Lake Stevens business owners, property managers and the other trades on their buildings. That covers roof drains and the storm piping below the deck, restaurant kitchens working through a health department list, and the restrooms and drains in between.
Real Commercial Work in Lake Stevens
In April 2026 we worked for the roofing contractor on a commercial building near Frontier Village, replacing the four roof drains on the building’s east side. The roofer handled all of the weatherproofing and supplied one of the new drain assemblies. Logan and Willie took out the four old cast-iron drains and set the new 4-inch drains in their place, three of them Jay R. Smith cast-iron drains with their sump receivers and clamp rings, and made every connection below the deck with new no-hub fittings, working from the roofer’s lifts.
In May the northernmost of the new drains came apart at its connection below the deck. Logan and Willie came back, lifted the drain back into place and refastened the band, added two supports, one under the elbow and one at the next joist down, raised the existing hanger so it carried the pipe, and took out a temporary strap that had been put in to hold it. The next day they pulled the band again, lined the joint up hub to hub with Willie on the roof, raised the supports tight and fastened the shielded clamp, then checked the other drains. The roofers on site told them heavy rain had come and gone with no trouble at the other connections. Neither return visit was charged.
A short way north, a restaurant changed hands in June 2026, and the new owner asked us to go through its plumbing. Logan and Willie found the dish sink’s wall-mount faucet no longer shutting off and leaking where it feeds the pre-rinse, and the hand sink by the soda dispenser leaking at its handles and spout. They set the tempering valves on the women’s restroom sensor faucets to 100 degrees, and noted that the grease interceptor’s lid needed cleaning, along with the ledge it sits on, before a new gasket could go in; its mounting hardware was missing too.
In September the owner sent the list the health department wanted taken care of. Logan adjusted the tempering valve under the server station’s hand sink until it held just over 100 degrees, replaced the ice machine’s leaking drain line and mounted it on the wall with an air gap above the mop sink, replaced the broken drain on the food prep sink, fastened the dish sink to the wall, and ordered a new mop sink basin and a new pre-rinse faucet. Ten days later he set the new mop sink, sealed it around its edges, and installed the pre-rinse faucet, carrying over the tee that feeds the dish machine’s chemical system.
What We Do for Lake Stevens Businesses
Roof Drains and Storm Piping
We replace cast-iron roof drain bodies, make the connection to the storm piping below the deck, and support that piping so the joint never carries its weight. We work alongside the roofer, who ties the drain into the membrane.
Restaurant and Bar Kitchens
Hand sinks and tempering valves, wall-mount and pre-rinse faucets, mop sinks, ice machine drains and the grease interceptor. We measure and order before we take anything apart, so the kitchen loses as little service as possible.
Restrooms and Building Plumbing
Sensor faucets, tempering valves, small tankless heaters and the drains under a tenant’s floor. Our commercial plumbing page covers the full list.
Lake Stevens-Specific Considerations
Around Frontier Village
Both buildings on this page are a short walk from Frontier Village, the shopping center at the west end of the lake, in the part of the city maps still label West Lake Stevens. The city’s other commercial buildings sit along the Highway 9 corridor and downtown at the north end of the lake, by North Cove Park, and we serve all three. A flat commercial roof like the one above drains through roof drains and storm piping that run inside the building, so a joint that separates below the deck shows up as water indoors, not on the roof.
Water From the PUD’s First System
Snohomish County PUD supplies water across much of Lake Stevens, and the Lake Stevens Water System was the first project the PUD organized and built. It began operating on January 17, 1946.
Grease Rules From the City and the Sewer District
The City of Lake Stevens’ code (chapter 6.28) requires every commercial or retail food preparation operation, regardless of size, to install, operate and maintain a grease interceptor. The Lake Stevens Sewer District’s code (chapter 7.57) sets its own requirements for food service businesses that discharge fats, oils and grease into its system.
When a Restaurant Changes Hands
A Snohomish County food establishment permit does not transfer to a new owner. The new owner applies when the business’s UBI number changes, receives a conditional operating permit that expires after 90 days, and hears from an inspector within the first two weeks of operating. Plumbing items, such as hand-sink temperature, can be on the list that follows, as they were for the restaurant above.
Commercial Plumbing FAQ for Lake Stevens
Who replaces a commercial building’s roof drains, the roofer or the plumber?
Usually both, each doing their part. The roofer makes the drain watertight in the roof, and a plumber sets the drain body and connects it to the storm piping below the deck. Near Frontier Village in April 2026, the roofer handled the weatherproofing while Logan and Willie replaced four 4-inch roof drains and their connections.
Does a small Lake Stevens café need a grease interceptor?
Under the City of Lake Stevens code, yes. Chapter 6.28 says every commercial or retail food preparation operation, regardless of size, has to install, operate and maintain a grease interceptor. The Lake Stevens Sewer District sets its own grease requirements for food businesses on its system, so check with both before you open.
We just bought a Lake Stevens restaurant. Does the health permit transfer to us?
No. Snohomish County food establishment permits do not transfer to a new owner. You apply when the business’s UBI number changes, receive a conditional operating permit that expires after 90 days, and an inspector contacts you within your first two weeks of operating. Plumbing items, such as hand-sink water temperature, can be on the list that follows.
Washington’s food code requires a hand sink to deliver water at 100 degrees or warmer through a mixing valve or combination faucet. At the restaurant above, Logan set the server station’s tempering valve so it held just over that.
Who should we call about the water supply to a Lake Stevens building?
For the service line and the meter, call your water utility, which across much of Lake Stevens is Snohomish County PUD; its first project anywhere was the Lake Stevens Water System, running since January 1946. For everything on the building side of the meter, from the main shutoff to the fixtures, call a commercially licensed plumber.
