The review is based upon the supposition that the data on which the design is based are correct, and that necessary legal authority has been obtained to construct the project. The responsibility for the design of structural features and the efficiency of equipment must be taken by the project designer. Approval is contingent upon satisfactory disposition of any requirements included in this report. Special care should be taken to insure that the material and installation of the plumbing system are in accordance with the provisions of the Minnesota Plumbing Code. A copy of the approved plans and specifications should be retained at the project location for future reference. A set of the identified plans and specifications is being returned to Commercial Plumbing and Heating Inc. INSPECTIONS: All plumbing installations must be tested and inspected in accordance with the requirements of the Minnesota Plumbing Code. As specified in Minnesota Rules, part 4715.2830, no plumbing work may be . covered prior to completing the required tests and inspections. Provisions must be made for applying an air test at the time of the roughing -in inspection as outlined in Minnesota Rules, part 4715.2820, subpart 2, of the code. A manometer test, as specified in Minnesota Rules, part 4715.2820, subpart 3, is required at the time of the finished plumbing inspection. It is the responsibility of the contractor /installer to notify the Minnesota Department of Health when an installation for a state contract job, licensed facility, or project in an area where there is no local administrative authority is ready for an inspection and test. To schedule inspections, contact the state plumbing standards representative for your region, or call the metro office inspection hotline at 1- 800 -926- 6216 (7:30 a.m. to 9 a.m.), or 651/215 -0836 (8 a.m. to 9 a.m.) on Monday, Wednesday or Friday.

The following items must be included in the construction of the grease interceptor: a. The interceptor must have a grease retention capacity, in pounds of grease, of at least twice the flow - through rate, in gallons per minute. b. The interceptor installation shall be capable of passing the final manometer test. c. It is recommended that the sanitizing compartment of the three - compartment sink be individually trapped and vented, and connected to the sanitary drain system downstream of the grease interceptor.

The tell -tale floor drain serving the prep sink must be installed on the dedicated prep sink drain branch as indicated on the floor plan. The waste and vent riser diagram appears to show a different arrangement. 4. Assuming a maximum developed length of pipe of 80 feet and a building water pressure at the meter between 46 and 60 psi, and using Minnesota Rules, part 4715.3800: a. The building supply line must be at least 11/4 inches in size up to the branch serving the tempering valve. b. The continuation of the building supply line must be at least 1 -inch in size up to the branch serving the ice maker. 5. A cleanout must be provided at or near the base of each stack (see Minnesota Rules, part 4715.1000). Cleanouts shall be of the same nominal size as the pipes they serve up to 4 inches in size (see Minnesota Rules, part 4715.1000). A cleanout must be installed where there is an increase in pipe size. 6. The installation of reduced pressure zone backflow preventers is permitted only when periodic testing is done by a trained backflow preventer tester acceptable to the administrative authority. Testing intervals shall not exceed one year, and records must be kept. All devices must be tested after initial installation to assure that debris from the piping installation has not interfered with the functioning of the device. The devices shall be overhauled at least once every five years. 7. Water supply connections to fixtures or equipment which have submerged inlets, or inlets below the spill line of the fixture or equipment, must be provided with an air gap arrangement, approved backflow preventer or backflow preventer assembly as specified in Minnesota Rules, part 4715.2000 and part 4715.2010.
