Which temperature threshold prohibits installation of a grease interceptor when ambient temperatures fall below it?

• A. Above 30°F
• B. Above 40°F
• C. Above 50°F
• D. Above 60°F

Answer: (B)

Temperature affects both the installation process and the long-term reliability of a grease interceptor. When ambient temperatures are too low, concrete and sealants used to set and seal the unit may not cure properly, joints can fail, and underground piping risks damage from freezing. In addition, the fats and oils trapped in the interceptor can solidify in very cold conditions, making installation and testing difficult or impossible. For these reasons, a minimum ambient temperature of 40°F is used as a threshold; installation is not performed once temperatures fall below that point to ensure proper curing, sealing, and future operation. Therefore, the threshold that prohibits installation when temperatures drop below it is 40°F.
