Code Description:

Chapter:

Section:
1003.3.4
-
Topic:
Grease Interceptors
-
Question:
Is it the intent of Florida Building Code ? Plumbing, Section 1003.3.4 that a grease interceptor, either indoor or outdoor, can be less than 750 gallons if it is certified to one of noted standards (ASME A112.14.3, A112.14.4, or PDI-G101), and is installed per the manufacturer's instructions? Is it also the intent of this Section that an interceptor, either indoor or outdoor, does not satisfy the code if it is not certified to one of the noted standards (ASME A112.14.3, A112.14.4, or PDI- G101)? Second, if a grease interceptor is certified to one of the existing standards and is sized and installed in accordance with the manufacturer's instructions but is only 250 gallons in size, why would it then have to meet the minimum 750 gallons noted in paragraph 1003.5? Comment: The typical grease interceptor used in Florida is concrete. These units meet the size and load capacity requirements of the code, but do not seem to meet the other requirements found in this section, including certification to one of the noted standards and being water and gas tight (they are not due to items such as porosity and removable, gravity held lids). Shouldn?t these portions of the Code be enforced as well?
A Grease trap conforming to PDI G101, ASME A112.14.3 or
ASME A112.14.4, installed in accordance with the
manufacturer�s instructions, is code compliant for sewage
systems. If you have a grease interceptor conforming to
the standards, rated between 51 and 100gpm located outside
with a capacity less than 750 gallons, you would need to
check with the local authority having jurisdiction to
determine if they will accept the interceptor installed by
its listing or if they are going to require an interceptor
complying with 1003.5. Interceptors rated over 100gpm
exceed the standards and therefore must comply with
1003.5. Be sure to check with your local serving utility,
they may have more stringent requirements before being
allowed to connect to their system. If the interceptor is
being installed on an onsite sewage disposal system
(septic system) it must be sized and designed according to
64E6 of the Florida Administrative Code.
