A hydromechanical grease interceptor is typically installed…
a.as close as practical to the fixtures served, with a flow-control device limiting flow to its rated GPM
b.after the building trap
c.on the vent line
d.inside the water closet
Explanation
A hydromechanical grease interceptor should be located as close as practical to the fixtures it serves so grease is captured before it cools and adheres to piping. A flow-control fitting restricts flow to the unit's rated GPM, giving grease time to separate. It must remain accessible for regular cleaning.
