The short answer

Commercial drain cleaning keeps restaurant grease lines, floor drains, apartment stacks and building sewers flowing, on a call or on a schedule. In Seattle, businesses with commercial kitchen plumbing need a grease interceptor and must clean it when it is 25 percent full; we clear and jet the lines around it. Pricing is a flat quote per line or per scheduled visit.

What commercial drain cleaning covers

Downtime is the real cost of a commercial clog, so the work is built around getting you open and keeping you open.

We clear the line that stopped, camera it so you know why, and if it is grease or buildup, set a jetting schedule that matches your volume instead of waiting for the next backup.

For single drains in an office or retail space, standard drain cleaning pricing applies. Kitchen grease lines, multi-unit stacks and building sewers are quoted per line or per scheduled visit, in writing, before work starts.

Seattle grease rules every commercial kitchen should know

Grease is regulated in Seattle. These rules come straight from Seattle Public Utilities and the municipal code.

  • Interceptors are required

    SPU says any business with commercial kitchen plumbing fixtures and a King County Food Business Permit must install a grease interceptor, including delis, coffee shops, pizza places and caterers. SPU: Commercial kitchens

  • Clean at 25 percent full

    Businesses must clean interceptors per the manufacturer’s specifications, or when they are more than 25 percent full of grease and food waste, under SMC 21.16.310. SPU: Commercial kitchens

  • No enzymes or bio-additives

    SMC 21.16.310 bars emulsifying agents, enzymes, bio-additives and similar chemicals in interceptors. SMC 21.16

  • Penalties are real

    SPU says non-compliance can bring penalties from $250 to $5,000, plus the City’s costs for damage caused by grease-laden wastewater. SPU: Commercial kitchens

  • A backup means closing

    SPU says a business with a backup should close immediately and contact Seattle-King County Public Health for direction. SPU: Commercial kitchens

Commercial lines, up close

Floor drains, grease lines and building sewers get the same camera-first approach as a house, with bigger equipment.

Reopen first

When a line is down, the first job is getting you back in service: cable or jetter, whichever reopens it fastest.

Then find out why

The camera shows grease, a belly or a problem unit on a shared stack, so the fix is aimed at the cause.

Then keep it open

A jetting schedule set by what came out of the line, not a guess, and records for your files.

Still have a question?

Shane answers the phone himself, 8 AM to 8 PM, seven days a week.

Do you clean commercial drains and restaurant grease lines in Seattle?

Yes. We clear and jet restaurant kitchen lines, floor drains, apartment and condo stacks, and building sewers for businesses and property managers across Seattle, on a call or on a maintenance schedule.

How is commercial drain cleaning priced?

As a flat quote per line or per scheduled visit, set before work starts. There is no trip fee, and the rate is the same evenings and weekends during our hours. Residential-style single drains in a commercial space follow our standard $200–$600 drain cleaning price.

What are Seattle’s grease interceptor rules for restaurants?

Seattle Public Utilities says any business with commercial kitchen plumbing fixtures and a King County Food Business Permit must install a grease interceptor, clean it per the manufacturer’s specifications or when it is more than 25 percent full, and not use enzymes or bio-additives in it.

What happens if a restaurant has a sewer backup?

Seattle Public Utilities says a business with a backup should close immediately and contact Seattle-King County Public Health for further direction. Call us to clear the line, and keep records of the cleaning for the health department and your insurer.

Can you work around our business hours?

We work 8 AM to 8 PM, seven days a week, so most scheduled cleanings can be set before service, between lunch and dinner, or on a slower day. Tell us your hours and we will book around them.

How often should a restaurant’s kitchen lines be jetted?

It depends on volume and menu. The camera and what comes out of the line on the first visit set the schedule; busy fryer-heavy kitchens need it more often than a coffee shop. SPU’s best practices, like scraping dishes before washing, stretch the interval.

Do you pump grease interceptors?

We clear and jet the drain lines that feed the interceptor and the line leaving it. Ask us about the interceptor itself when you call, and we will tell you what we handle and what goes to a grease hauler.
