Grease interceptors serve a fundamentally different function than the passive traps installed under commercial kitchen sinks. They're designed for high-volume commercial operations — large restaurants, institutional kitchens, multi-tenant food service buildings — where the volume of fats, oils, and grease produced in a single service period would overwhelm a smaller passive unit.
The service requirements are correspondingly different. A grease interceptor pumping job requires vacuum truck capacity, specific access equipment, interior inspection after full extraction, and waste documentation that satisfies the more demanding regulatory standards that typically govern large-volume grease waste.
Grease Service MS provides grease interceptor pumping for commercial operations across Walnut, CA with the equipment, crew size, and documentation protocol that large-capacity units actually require. This isn't the same service adapted for a bigger tank — it's a separate service built for a separate class of equipment.
