Each install includes a flow control fitting and proper venting to keep the trap working as designed. These units need frequent cleaning, so we place them where staff can reach the lid easily.

Grease Trap Installation for Schools and Institutions in Waimalu

Small under-sink hydromechanical traps generally cost much less to install than large outdoor interceptors.

Frequently Asked Questions About Grease Trap Installation in Waimalu
Small indoor hydromechanical traps typically cost $1,500 to $5,000 installed. Large outdoor gravity interceptors often run $8,000 to $30,000 or more with excavation, concrete and site restoration. We provide a written estimate after a site visit.
We calculate flow from every connected fixture, including sinks, floor sinks and dish machines. Hydromechanical units are usually rated by gallons per minute, while gravity interceptors are sized by volume and retention time.
While the terms are often used interchangeably, 'grease trap' typically refers to smaller, indoor hydro-mechanical units, often found under sinks. 'Grease interceptor' usually refers to larger, outdoor gravity-fed units with higher capacities. Both serve the same purpose of separating FOG from wastewater.
Determining the correct grease trap size involves calculating your kitchen's wastewater flow rate, fixture count, and peak operating hours. Our experienced plumbers will conduct a thorough assessment of your Waimalu business to recommend the appropriate size and type of grease trap that meets local codes and your operational needs.
The timeline for grease trap installation depends on the project's scope. A simple under-sink unit might take a few hours. Larger outdoor gravity interceptors, which involve excavation and more extensive plumbing, can take anywhere from one to several days. We always aim to minimize disruption to your business operations.
The lifespan of a grease trap depends on its type, material, and how well it's maintained. Steel grease traps may last 10 to 15 years, while durable fiberglass or polyethylene units can last 20 to 30 years or even longer. Regular cleaning and proper usage are key to extending its lifespan.
We recommend and install high-quality, durable grease trap brands such as Zurn, Big Dipper, Schier, and Rockford Separators. These manufacturers are known for their reliability and compliance with industry standards, offering various solutions to meet diverse commercial kitchen needs.
An indoor under-sink trap can often be installed in a day. Outdoor interceptors typically take several days to a week or more, depending on excavation, concrete work and inspection scheduling.
