Restaurants & Food Service

No Working Sink Means No Service

In a restaurant, plumbing isn't a background system, it's a legal requirement for staying open. A broken sink means you can't legally serve food. A grease trap overflow means a health code violation, and potentially a failed inspection right in the middle of your busiest season. A clogged floor drain during dinner service means standing water, a slip hazard, and a kitchen that stops functioning until it's fixed.


Commercial kitchens generate a volume of wastewater that dwarfs anything in a residential setting, hundreds of gallons an hour during peak service, loaded with fats, oils, grease, and food solids that residential plumbing was never built to handle. That volume, combined with strict health code requirements around grease management and backflow prevention, means restaurant plumbing needs a partner who understands the stakes, not a generalist working through a checklist.


West Coast Hydro-Jet has serviced restaurants and commercial kitchens throughout Los Angeles, Orange County, the Inland Empire and San Diego for more than 34 years, with technicians who know what a health inspector is going to check before they ever walk through your door.

Common Commercial Kitchen Plumbing Problems

A handful of issues show up again and again in restaurant kitchens, most of them traceable back to volume, grease, and heavy daily use:

  • Grease trap overflow, the single most common cause of health code violations in food service plumbing
  • Floor drain clogs, which create standing water, a slip hazard, and a health code red flag all at once
  • Slow or backed-up kitchen sinks, often at multiple stations at once during high-volume prep
  • Garbage disposal strain, since running food waste through a disposal significantly increases the solid load hitting your grease trap
  • Dishwasher and pre-rinse valve issues, from constant hot and cold cycling that stresses pipes and fittings
  • Low water pressure at peak times, when every station is drawing water simultaneously


Most of these are preventable with a maintenance schedule built around how your kitchen actually operates, rather than a reactive call every time something backs up.

Grease Trap Compliance Isn't Optional

Virtually every commercial food service establishment is legally required to have a properly sized and maintained grease trap or interceptor, capturing fats, oils, and grease before they reach the municipal sewer system. This isn't a suggestion, it's enforced by local health departments and sewer utilities, with real fines and potential closure for non-compliance.


The standard guidance most health departments and plumbers work from is the 25 percent rule: service the trap before FOG and solids occupy more than a quarter of the tank's total capacity. Wait longer than that, and you're risking an overflow, a failed inspection, or a backup that shuts down your kitchen mid-service. Most restaurants need service every one to three months, with high-volume kitchens and fryer-heavy menus typically needing it on the shorter end of that range.


We handle full grease trap and interceptor cleaning, not just pumping the liquid layer, and we keep documented service records available for your health department inspections, since Southern California health inspectors increasingly expect to see that paperwork on demand.

Consistent Service Across Multiple Locations


Restaurant groups and franchise operators managing several locations face a specific challenge: keeping every kitchen on the same maintenance standard, with the same documentation, regardless of which location is calling. Inconsistent grease trap service across locations means inconsistent compliance risk, and a health code violation at one restaurant can affect the reputation of the whole brand.


We work with multi-location restaurant groups across Los Angeles, Orange County, the Inland Empire and San Diego who want one plumbing partner handling every kitchen, with the same self-performing crews, the same maintenance schedule structure, and the same documentation practices at every address.


Why Mechanical Cleaning Still Matters


Some kitchens supplement their grease trap maintenance with biological treatments, products that introduce bacteria to help digest fats and oils between service visits. These can extend the time between pump-outs and reduce odor, but they don't eliminate the need for regular mechanical cleaning. Bacteria can slow buildup, but they can't remove the solids and hardened grease that accumulate on a trap's walls and baffles the way a full mechanical cleaning does.


If your kitchen is using a biological treatment and still seeing backups, odors, or a trap that fills faster than expected, that's usually a sign mechanical cleaning has been skipped for too long, not that the treatment has failed. We can assess what's actually happening in your trap and get it back to a schedule that works.

A Maintenance Schedule Built for Food Service

Reactive plumbing service costs a restaurant more than the repair itself, lost revenue during a shutdown, a failed inspection, and the reputational hit that comes with a health code citation. A maintenance schedule built specifically for your kitchen's volume avoids most of that entirely.


For most restaurants, that means grease trap service every one to three months depending on volume, quarterly hydro-jetting of main kitchen drain lines to clear grease and buildup before it becomes a blockage, annual backflow testing and certification, and regular water heater maintenance to keep dish stations and hand sinks running at temperature. We build this into a Preventative Maintenance Plan tailored to your kitchen, coordinated around your service hours so cleaning happens when it won't disrupt a shift.

Emergency Response When You Can't Afford to Close

It's Saturday night, the dining room is full, and the kitchen sink stops draining, or worse, a floor drain backs up and floods the line. A plumbing emergency during service isn't an inconvenience, it's lost revenue for every minute the kitchen isn't running at full capacity.


Our technicians are available 24/7 across Los Angeles, Orange County, the Inland Empire and San Diego, and because we self-perform every job, there's no subcontractor to track down while your kitchen is down. We understand that a restaurant emergency call isn't the same as a residential one, the clock is running on revenue, not just convenience.

Frequently Asked Questions About Restaurants & Food Service

  • How often does a restaurant grease trap need to be cleaned?

    Most restaurants need service every one to three months, based on the 25 percent rule, servicing the trap before fats, oils, and grease occupy more than a quarter of its capacity. High-volume or fryer-heavy kitchens typically need service on the shorter end of that range.

  • What happens if a health inspector finds a grease trap violation?

    A grease trap violation can result in a failing inspection score, mandatory remediation, a re-inspection fee, and in serious cases, fines or forced closure until the issue is resolved.

  • Can you provide documentation for health department inspections?

    Yes. We keep documented service records for grease trap cleaning and other maintenance, available for health department inspections when needed.

  • How often should restaurant kitchen drains be hydro-jetted?

    Most restaurants benefit from quarterly hydro-jetting of main kitchen drain lines to clear grease and buildup before it causes a blockage, though the right interval depends on your kitchen's specific volume.

  • Does a small food service business, like a coffee shop or food truck commissary, need a grease trap too?

    In most jurisdictions, yes. Even smaller operations that produce fats, oils, or grease are typically required to have a properly sized grease trap or interceptor.

  • Do biological grease trap treatments replace the need for mechanical cleaning?

    No. Biological treatments can extend time between pump-outs and reduce odor, but they don't remove solids and hardened grease from a trap's walls and baffles the way mechanical cleaning does. They work best as a supplement, not a replacement.

  • Can you service multiple restaurant locations for a franchise or restaurant group?

    Yes. We work with multi-location restaurant groups across Los Angeles, Orange County, the Inland Empire and San Diego, providing consistent service and documentation at every address.
