New Restaurant Build-Out Grease Traps in Kent

Grease Trap Installation Cost in Kent, WA
Small under-sink hydromechanical traps generally cost much less to install than large outdoor interceptors. Indoor units are typically a few thousand dollars installed, while in-ground interceptors can run well into five figures with excavation and concrete work. Pricing depends on unit size, location, soil conditions and whether we need to cut and patch floors. We give you a written estimate that includes permits and inspection. That way there are no surprises during construction.
Automatic Grease Removal Units in Kent
Automatic grease removal devices skim grease from the water and collect it in a container your staff empties. Brands like Thermaco Big Dipper are popular in kitchens with limited space and frequent cleaning needs. We install these units with the correct power supply and drain connections. They can reduce the need for frequent pump-outs in smaller kitchens. We explain daily maintenance so your staff keeps the unit running well.
Large Outdoor Grease Interceptor Installation in Kent
For high-volume commercial kitchens in Kent, large outdoor grease interceptors are often required by code. These large units are installed underground and designed to manage significant amounts of FOG before wastewater enters the municipal sewer system. We handle the entire process, including excavation, precise placement, connection, and final inspection, ensuring a robust and compliant installation.

Frequently Asked Questions About Grease Trap Installation in Kent
The cost of grease trap installation in Kent, WA varies widely based on the type and size of the trap, whether it's an indoor or outdoor unit, and the complexity of the installation. For a small under-sink hydro-mechanical unit, expect to pay between $1,500 and $4,000. Larger outdoor gravity interceptors can range from $7,000 to $20,000 or more, including excavation and concrete work.
The main purpose of a grease trap is to intercept fats, oils, and greases (FOG) from commercial kitchen wastewater before they enter the public sewer system. This prevents pipe blockages, protects municipal infrastructure, and helps businesses comply with environmental regulations.
Signs you might need a new grease trap include frequent sewer backups, persistent foul odors coming from drains, slow drainage throughout your kitchen, or if your current unit is visibly corroded or leaking. If your existing trap is old and no longer meets current local codes in Kent, an upgrade is also a good idea.
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.
Installation time depends on the size and complexity of the grease trap. A small under-sink unit might take a few hours, while a large outdoor interceptor could require several days due to excavation and concrete work. We aim to complete installations efficiently to minimize disruption to your business operations.
We calculate flow from every connected fixture, including sinks, floor sinks and dish machines. Hydromechanical units are typically rated by gallons per minute, while gravity interceptors are sized by volume and retention time.
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.
Signs you might need a new grease trap include frequent drain clogs, slow drainage in multiple fixtures, persistent foul odors coming from drains, or if your current unit is old, corroded, or no longer meeting local code requirements. An inspection by a professional plumber can confirm the need for replacement.
