Grease Trap Installation Cost in Mount Vernon, 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.

We make sure that every grease trap installation we perform is fully compliant, helping you avoid penalties and maintain a clean, responsible operation.
Gravity Grease Interceptor Installation in Mount Vernon, WA
Gravity grease interceptors, or GGI units, are larger, typically located outdoors, and rely on the natural difference in specific gravity between FOG and water. These are common for high-volume commercial kitchens. Our team handles the involved excavation, concrete work, and plumbing connections required for proper GGI installation, maintaining compliance with all local Washington ordinances for waste management.

Gravity Grease Trap Installation in Mount Vernon
Gravity grease traps are a common and effective solution for many commercial kitchens in Mount Vernon. These passive systems use the natural separation of FOG from water due to density differences. Our plumbers are experts in installing gravity grease traps, ensuring proper sizing, correct inlet and outlet piping, and convenient access for future cleaning and maintenance to maximize their efficiency.
Under-Sink Grease Trap Setup in Mount Vernon, WA
Smaller establishments or specific kitchen stations in Mount Vernon, WA may benefit from compact under-sink grease traps. These units are well suited for capturing FOG at the source, preventing it from entering the main plumbing lines. Our team carefully installs these smaller units, ensuring proper sizing, sealing, and connection to your existing plumbing system for effective waste management and odor control.

In-Ground Gravity Interceptor Installation in Mount Vernon, WA
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks usually range from several hundred to over 1,500 gallons. We excavate, set the tank on a stable base, connect inlet and outlet piping and install manhole risers. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go much longer between pump-outs than an indoor trap.
