What this site is

InterceptorCall is a referral service, not a contractor. We connect operators and property managers with independent contractors. Contractors and waste haulers are required to hold whatever credential and permit their state or municipality demands — ask to see them, because the manifest they leave you is a compliance record. We carry out no work, we haul nothing, we do not set prices, and we never charge the caller anything. Nothing here states the grease limit, the pumping interval or the device size that applies to any particular kitchen; those are set by your control authority and by your installation.

Checking a credential in California

California licenses are issued by the Contractors State License Board, which publishes a public search you can use before work begins. California licenses the C-36 plumbing contractor; there is no state journeyman license.

What that coverage looks like

Food premises concentrate where the population does, and in California that is Los Angeles County with 494 covered ZIP codes, Sacramento holding 100 of them. A pump truck working a dense block services several kitchens in a run; one working the far side of 40 counties does not, and the interval has to be set with that in mind.

How a grease trap cleaning job goes

An interceptor is pumped on a schedule and the schedule is written down. The trap is opened, the accumulated grease and solids are removed, the baffles are checked and the service is recorded. The record is the part that matters when an inspector asks: a trap that is clean today and has no history of being cleaned is still a finding.

What the call asks about grease trap cleaning

  • How many covers the kitchen does and what it cooks, because that sets the interval more than the tank size does.
  • Where the interceptor is and whether a truck can reach it.
  • When it was last pumped, and whether there is a record of it.

Every California city we route in

366 cities, ordered by the share of buildings with twenty or more units. Commercial kitchens cluster where the buildings are large, and every one of them has an interceptor. Each page carries that city’s own numbers and the ZIP codes we route there.

Before you call

An interceptor that is pumped on a schedule is a cost; one that is pumped after a backup is a closure. The pages above set out the record a kitchen has to keep.
