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 New Hampshire
The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.

What that coverage looks like
Food premises concentrate where the population does, and in New Hampshire that is Rockingham County with 40 covered ZIP codes, Manchester holding 8 of them. A pump truck working a dense block services several kitchens in a run; one working the far side of 8 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.

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.
