3.1.1.1 Sink Waste Connections: COMPLIES

Each sink compartment was fitted with a 1-½” (up to 50 gpm) or 2” (greater than 50 gpm) standard sink waste connection with flange, crossbars, slip joint tailpiece, and locknut.

Each gauge connection was fitted into the bottom of a sink compartment and in close proximity to the waste outlet. Each gauge was mounted on the outside of the sink, adjacent to its respective gauge connection, and extended diagonally upward from the bottom center to the top outside corners. The gauges were calibrated to read directly the number of inches of water in the sink compartments above the sink waste flange.

3.1.1.3 Movable Sink Partitions: COMPLIES

Each compartment of the sink was fitted with a movable partition, making it possible to regulate the size of the compartment to any desired capacity.

Report No. 1757-21033 Page 4 of 22

3.1.2 Skimming Tank: COMPLIES The skimming tank was rectangular in shape and open at the top.

Tank Length - 12’ Tank Width - 36” _ Tank Depth - 28” _ Tank was made of corrosion resistant material - yes (yes) Tank was structurally reinforced - yes (yes) Waste outlet diameter - 4” (4 inches)

The waste outlet was connected to the bottom of the tank at one end and trapped to retain approximately 18 inches of water in the tank. The tank provided a stationary baffle located approximately 4 ft. from the end of the tank receiving the discharge from the interceptor. This baffle extended the width of the tank and to within 4” of the bottom of the tank.

3.2 Installation of Testing Equipment: 3.2.1 Direct Connection Test Types A, B, and C: NOT APPLICABLE 3.2.2 Indirect Connection Test Type D:

Findings- The “GB-1000” was a Type D unit.

3.2.2.1 Sink and Interceptor Locations: COMPLIES The sink was located on the floor with the sink rim 3 ft above the floor level and 13 feet above the outside bottom of the grease interceptor being tested.

3.2.2.2 Floor Sink and Location: COMPLIED A 6 in. deep floor sink to receive the indirect waste discharge from the test sink shall be

located in the floor supporting the test sink. The rim of the floor sink shall be located at floor level. The outlet of the floor sink shall be sized to handle the test flow rate, and shall not be less than 3 in.

3.2.2.3 Skimming Tank Location: COMPLIES

The skimming tank was located low enough, with respect to the interceptor, for the discharge piping from the interceptor to clear the tank rim by not less than 3 inches.

3.2.2.4 Installation of Waste Piping: COMPLIES (a) Sink Connections- The sink outlet waste connection from each sink compartment

was 1-½ inches in size and fitted with a quarter-turn ball quick-opening valve. (b) Combined Horizontal Waste Piping- The combined horizontal waste piping into

which the sink outlets connect shall be 3”, installed with the center line 11 inches below the bottom of the sink and properly hung and braced from the sink reinforcement and supports. The waste pipe shall connect to a *single 3” valve that shall serve to regulate the total discharge flow rate. The pipe connected to the valve outlet shall turn downward 90 deg and shall terminate 1” above the rim and at the centerline of the floor sink. *Due to the 200 gpm rating, for a Type “D” configuration of the Standard (Figure 3), it calls for a 3” waste valve for the sink to regulate flow from that sink. Since two sinks were used in tandem to achieve the 200 gpm, an additional 3” valve was used on the second sink. Approved by IAPMO R&T review engineer.

Report No. 1757-21033 Page 5 of 22

(c) Floor Sink to Interceptor Piping- A trap fitting shall be connected to the outlet of the

floor sink, of a size appropriate for the flow rate tested, but not less than 3”. Horizontal piping of the same size and 3 ft in length with a vent shall be connected between the floor sink elbow and the vertical waste riser, which shall extend downward to connect to the grease interceptor inlet by means of an elbow and a short horizontal nipple.

(d) Interceptor Discharge- The discharge pipe from the grease interceptor outlet to the skimming tank shall be the same size as the inlet pipe. It shall have a minimum pitch of 1/8”/ft and shall be provided with a 2” vent properly located to prevent siphoning of the interceptor.
