Our team expertly installs these smaller units, ensuring proper sizing, sealing, and connection to your existing plumbing system for effective waste management and odor control.
Residential Grease Interceptor Setup in O'Fallon, MO
While less common, some large residential kitchens or homes with extensive outdoor cooking setups may benefit from a small grease interceptor. These are typically installed under the sink and help prevent fats, oils, and grease from clogging household drains. FGV Plumbing can assess your home's needs and provide a suitable residential grease trap installation solution that protects your plumbing system from FOG accumulation.

In-Ground Gravity Interceptor Installation in O'Fallon, MO
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks typically 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. Limestone and rocky ground in the southern part of the state can make digging for sewer lines harder and more costly. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go far longer between pump-outs than an indoor trap.

Hydromechanical Grease Trap Installation in O'Fallon
Hydromechanical grease traps sit under or near sinks and use baffles and flow control to separate grease from water. They are common in small cafes, coffee shops and quick-service restaurants with limited space. We install units from Zurn, Watts, Schier and Endura sized by gallons per minute. 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.

While the terms are often used interchangeably, 'grease trap' usually refers to smaller, indoor hydro-mechanical units, often found under sinks.

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 strive to complete installations efficiently to minimize disruption to your business operations.
