Hello Ted,
1.Your 35gpm grease trap (GT) is acceptable. Please remember that it will require
routine maintenance to keep it less than 25% full of fats, oils, grease, and
sediment per city code. The plans do require some modifications, however.
a.The dishwasher should not be connected to the GT as indicated in the
plans.
b.The hand sink and the display cooler/ice machine should not be connected
to the GT.
c.The (2) comp sinks should be connected to the GT as indicated in the
plans.
d.Disposals are not permitted to be connected to the GT. I did not see a
disposal in the plans.
2.You will need to complete a Grease Removal Equipment Application and the
Grease Trap Sizing worksheet for me to sign before a plumbing permit can be
issued (enclosed). I assumed your sinks measured 18” X 18” X 12” (each
individual sink in the comp sinks) for the 35 gpm GT approval. If the sinks are
noticeably larger, a larger GT may be required. No sink dimensions were
included in the plans. Also, the GT must be installed where there is suitable
access for inspection, cleaning and for the baffle to be removed.
3.A flow control valve for the GT is required, not optional as indicated in the plans.
A flow control valve is typically included with the GT unit. Venting is required
to be installed for the GT as per the manufacturer. Under most conditions, a vent
is connected to the flow control valve and also to the outlet line of the GT,
especially if it is tight lined to the side sewer line.
4.The sanitize sink should be isolated from the line to the GT by either an air gap or
a connection to a dedicated line to the side sewer. I noticed all three sinks were
connected directly to the GT in the GT waste detail for the plans. Please contact
the County Health Department for specific requirements.
Please call me Monday-Thursday for questions and assistance.
