Hydro-Mechanical Grease Interceptor Installation in St. Louis
Hydro-mechanical grease interceptors, often called HGI units, are compact and designed for indoor use, typically under a sink or on the floor. These units use baffles to slow down wastewater flow, allowing grease to separate and accumulate. FGV Plumbing expertly installs various sizes of HGI units, ensuring proper venting, leveling, and connection to your drainage system in St. Louis for the best efficiency.

In-Ground Gravity Interceptor Installation in St. Louis, MO
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. Expansive clay soils are common in Missouri, and they swell and shrink with moisture, putting stress on foundations and buried lines. 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.
Automatic Grease Removal Units in St. Louis
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 smoothly.
