Almost every commercial backup we get called to in Gig Harbor was scheduled work somebody deferred. Grease line service, floor drain cleaning and interceptor upkeep are cheap while the line still flows and expensive the night it stops. At Spartan Plumbing Inc., we have kept commercial drains open across the South Sound since 1958.
We clean every commercial drain type on an interval you set: kitchen branches, grease lines, floor drains, floor sinks, mop sinks and the main sewer. The scope and price go in writing before the first visit, and 24/7 emergency response sits behind the plan for anything arriving between services.
Our team starts by walking your fixtures, your interceptor and your service records, then builds an interval around how the building is used. A busy kitchen and a medical suite do not need the same schedule. You get the plan and the number before anything is booked.
Plenty of operators are working from advice that points at repealed code. The grease, oil and sand interceptor sections in the old sewer chapter were repealed by ordinance, and the live rules sit in Chapter 13.30. That chapter is administered by the wastewater treatment plant supervisor rather than the building department, which is why calling the permit counter gets you nowhere.
The size of the kitchen does not determine the device. Drainage fixture units do. Four or fewer is exempt, five through nine calls for a hydromechanical interceptor inside the building, and ten or more requires a gravity interceptor installed outside the structure. Adding one sink during a remodel can move a building across a line it did not know existed.
Gig Harbor’s retail pull factor for food services and drinking places is 3.17 on 2023 taxable sales, meaning the city captures roughly three times the restaurant spending its households generate, and the adopted plan calls it a regional retail center for most categories. That is why the code sets a hard floor: where sizing formulas produce a gravity interceptor under 750 gallons, the minimum is 750 gallons, and the table scales up from there by fixture count on a 30-minute retention time.
Operators keep asking what the interval is. For gravity interceptors there is no single answer, because frequency is set facility by facility in the operational permit, with each device reviewed case by case. Interior hydromechanical units are different: the code says they shall be serviced weekly or as needed, triggered at three inches of accumulation on top or 25 percent of liquid volume occupied by floating solids or sediment.
A device can be serviced on paper and still fail an inspection. The code prohibits skimming the surface layer or any method that does not remove the entire contents, and it separately prohibits decanting removed waste back into the interceptor. The owner or an employee has to supervise the cleaning, be present for the whole operation, and sign the maintenance log as proof.
The paperwork catches more facilities than the plumbing does. A maintenance log covering the previous twelve months, showing date, time, amount removed, hauler and disposal site, has to be posted in a conspicuous location. Trip tickets and the service log stay on the premises for three years.
*Every job runs the same way. We look at the system, tell you plainly what we found, put the estimate in writing before we start, and finish to code.*
Pressurized water cuts grease, scale, and debris out of commercial drain lines, and a paired high-definition camera run shows the inside of the pipe before and after, so the result is on record rather than guessed at.
Cured-in-place lining rebuilds a failed or cracked sewer line through small access points, sparing parking lots, landscaping, and flooring. Where the line is too far gone, we replace it outright.
Commercial tankless installation and repair for operations that need hot water on tap all day. On-demand units drop the standby energy a tank wastes and remove the recovery wait between draws.
Full commercial repiping for buildings running corroded, undersized, or out-of-spec supply lines. We pull the failing system and put in modern materials rated to carry the building’s demand for decades.
Tenant-improvement plumbing, fixture and appliance hookups, supply-line repairs, and full system upgrades. New space or existing, we take it from first cut to final connection.
Repair and replacement of broken downspouts that carry water off your foundation, plus sump pump fixes and primary or backup pump installs that keep below-grade space dry through a storm.
Diagnosis, repair, and full replacement for commercial tank heaters across every major brand and size, getting the hot water back on quickly so the operation keeps moving.
Scheduled and emergency work on pinholes, burst lines, and freeze damage anywhere in the building. We pin the source down first so the wall or floor only opens where it has to.
Motorized cabling and hydro jetting on floor drains, floor sinks, mop sinks, kitchen lines, and main sewers. We clear the full length of the line rather than punching a single hole through the clog.
Full support across tank, tankless, and heat pump units, including scheduled maintenance plans that stretch equipment life and head off the surprise failures.
Complete plumbing for commercial kitchens, restroom renovations, tenant improvements, and whole-facility remodels, coordinated with your contractor or property manager.
Heat pump water heater installation and repair for operations chasing lower utility costs, since these units draw far less power than standard resistance heating and pay back well in this climate.
Scheduled and emergency cleaning for every commercial drain type, from grease traps to floor drains to the main building sewer, stopping the backups and floods that shut a business down.
Video inspection of commercial sewer lines to locate root intrusion, collapse, offset joints, and blockages, giving you a clear read on the system before you commit to any repair.
The everyday commercial list handled by one licensed team: valves, fixtures, backflow devices, supply lines, and the small repairs that sit on a punch list until they turn into an after-hours call.
Lift the lid on an interior interceptor and measure the layer on top. More than three inches of accumulation, or floating solids and sediment taking up a quarter of the liquid volume, is the service trigger written into the code. Past that point the device is no longer doing its job.
If an inspection finds solids occupying 25 percent or more of the interceptor’s liquid capacity, immediate steps have to be taken to pump and clean it. The inspector may also order an immediate cessation of all discharge from the facility. That is a same-day closure risk sitting in a tank nobody looked in.
Emulsifiers, de-emulsifiers, surface active agents, enzymes, degreasers and any product that will liquefy interceptor wastes are prohibited from the device and from any drain leading to it. The reason is simple: liquefied grease passes straight through and reforms in the city main. If a product like that is in your building, the interceptor is not protecting the sewer.
Influent to a grease interceptor may not exceed 140 degrees Fahrenheit, and hot discharge is one of the quietest ways to defeat a properly sized device. Grease that stays liquid through the tank leaves with the effluent instead of separating out, and it lands in the city main.
Three-compartment sinks, pot and pan sinks, soup kettles, hand-washing sinks, dishwashers, mop sinks and floor drains all have to route through the interceptor, and toilets, disposer discharge and clear waste lines must not. Remodels and equipment swaps break this constantly, and the first sign is a grease line loading faster than it should.
When the supervisor determines a facility has no interceptor or an undersized one, the clock to install a compliant device is twelve months. An extension has to be requested in writing at least 180 days ahead, which means the request is due long before most operators think about it. Sizing, plan review and construction inspection all fit inside that one year.
Cabling opens a channel through buildup. Hydro-jetting scours the pipe wall, which is what matters on a grease line where the restriction is a hardened layer, not a single obstruction. Recovering the full diameter is the difference between a line that holds for a season and one that closes at the next busy service.
Because gravity interceptor frequency is set per facility in the operational permit, the right schedule is a document question before it is a plumbing one. We read what your permit requires, look at how the device loads between services, and set visits to that. Interior units get the weekly or as-needed treatment the code calls for.
A program that only touches the interceptor leaves the branch lines that feed it. We work the three-compartment sink, the pot sink, the dish machine drain, the mop sink and the floor drains in the same visit, then the main run out of the building. That is where buildup starts, and it is the part most service contracts skip.
Inspections happen twice yearly, and a facility that fails gets a repeat inspection thirty days later. We document what was cleaned, what condition it was in and what we recommend, in a form that slots into the log you keep posted. The file is ready before anyone asks.
State-credentialed commercial plumbers carrying full liability and workers’ compensation coverage on every job.
Upfront estimates before work begins. No hidden fees or surprise charges after the fact.
We know the permit path, the inspection points, and the commercial code that applies in Gig Harbor.
Commercial-grade materials, pressure-tested connections, and documented work on every project.
We work around your operating hours where we can and keep the space clean while we work.
A drain program is one of the few building costs you get to choose the timing of. The same line cleaned on a Tuesday morning between services costs a fraction of what it costs on a Friday night with a dining room full and a floor going under.
At Spartan Plumbing Inc., we set the interval from how your building actually runs, work the branch lines as well as the main, and leave the visit documented. Call us today at 253-231-7015 to put commercial drain cleaning in Gig Harbor on a schedule, and we will price the first visit before we book it.
It depends on the device. For an exterior gravity interceptor the frequency is set facility by facility in the operational permit, with each one reviewed case by case, so there is no fixed citywide interval to copy from a neighbor.
Interior hydromechanical units are stricter and more specific. The code says they shall be serviced weekly or as needed, with the trigger being three inches of accumulation on top or 25 percent of liquid volume occupied by solids.
Chapter 13.30 of the municipal code. The older grease, oil and sand interceptor sections in the sewer chapter were repealed by ordinance, so any guidance still pointing at them is out of date and will not match what an inspector uses.
The other thing worth knowing is who runs it. Chapter 13.30 is administered by the wastewater treatment plant supervisor, not the building department, which changes who you talk to about a permit or a failed inspection.
By drainage fixture unit count, not by square footage or seat count. Four or fewer drainage fixture units is exempt, five through nine calls for a hydromechanical interceptor, and ten or more requires a gravity interceptor installed outside the building.
That is why a remodel matters. Adding a prep sink or a second dish station can push the count over a threshold and change the device the building is required to have.
Because the code sets a floor regardless of what the formula produces. Where sizing calculations result in a gravity interceptor under 750 gallons in capacity, the minimum size is 750 gallons, and the sizing table scales upward from there by fixture unit count on a 30-minute retention time.
It fits the market here. Gig Harbor’s food service pull factor is 3.17, meaning local kitchens serve a trade area roughly three times their residential base, so grease loading runs ahead of the building’s size.
Yes, and it is not optional. The owner or an employee of the facility has to supervise the interceptor cleaning, be physically present for the entire operation, and sign the maintenance log afterward as proof that it was done.
That requirement exists because of what it prevents. The code also prohibits skimming the surface layer, any method that does not remove the entire contents, and decanting waste back into the device.
No. Emulsifiers, de-emulsifiers, surface active agents, enzymes, degreasers and any product that will liquefy interceptor wastes are prohibited from the device and from any drain leading to it, and biological treatment systems need pre-approval from the supervisor.
The physics explain the rule. Liquefied grease passes through the interceptor and reforms in the city main, and the limit downstream of a device is 100 milligrams per liter of oil and grease.
Three-compartment sinks, pot and pan sinks, soup kettles, hand-washing sinks, dishwashers, mop sinks and floor drains all route through the interceptor. Toilets and urinals do not, food waste grinder discharge goes directly to the building drainage system, and clear waste stays out as well.
Clear waste means ice machines, coil condensate and drink stations. Sending those through the device wastes capacity and shortens the interval without protecting anything.
A maintenance log covering the previous twelve months, listing date, time, amount removed, hauler and disposal site, kept posted in a conspicuous location on the premises. Trip tickets and the service log stay on site for at least three years.
Food service establishments have one more duty. Trip tickets are kept posted with the Pierce County health food permit, so the grease file and the food file live in the same place.
Regular inspections occur twice yearly, or as the operational permit requires. If an interceptor is not meeting maintenance requirements, a repeat inspection follows thirty days from the initial one, which is a short window to correct a pattern.
There is a harder consequence too. If an inspection finds solids occupying 25 percent or more of the liquid capacity, the inspector may order an immediate stop to all discharge from the facility.
Possibly, and the code is specific about it. Beverage and coffee stands are named alongside bakeries, cafes, delicatessens, caterers, churches, schools and clubhouses in the list of facilities required to have an interceptor.
The deciding factor is still the fixture count. Facilities with four or fewer drainage fixture units are exempt, so a small operation can fall outside the requirement, but that is a calculation rather than an assumption.
The main drivers are how many fixtures and branch lines are in scope, the type and size of interceptor, how accessible the device and cleanouts are, how heavily the kitchen loads the system, whether the visit needs cabling or jetting, how often you want us back, and whether the work happens inside or outside service hours.
A two-fixture prep area and a full production kitchen are not the same program. We walk the building, set the interval, and put the number in writing before anything starts.
