Drainage, Waste & VentQuestion 143 of 360
Which establishment is most likely required to install a grease interceptor or grease trap?
a.A single-family residential kitchen
b.A retail clothing store restroom
c.A restaurant with commercial food preparation producing fats, oils, and grease (FOG)
d.An office break room with only a coffee maker
Explanation
Grease interceptors are required where fats, oils, and grease are generated in quantity, such as restaurants and commercial kitchens. FOG cools and hardens in the sewer, causing blockages and backups if not intercepted. Single-family homes and low-grease uses are generally exempt.
