This review is limited to the provisions of the Minnesota Plumbing Code,Minnesota Rules,Chapter 4714 and
assumes the data on which the design is based are correct.Approval is contingent upon meeting the requirements
listed below. A copy of the approved plans and this report must be retained at the project location.
INSPECTIONS: This project will be inspected by the local municipality. The contractor/installer must obtain all
required inspection permits from the Oak Park Heights Building Official,Julie Hultman.All plumbing
installations must be tested and inspected in accordance with the requirements of the Minnesota Plumbing Code.
No plumbing work may be covered prior to inspection.
REQUIREMENTS:
1. Unless prior authorization is granted by the Administrative Authority, all pipe,pipe fittings,traps, fixtures,
material,and devices used in the plumbing system must(see Code Sections 301.1 and 1401.1):
a. be listed or labeled(third party certified)by a listing agency;
b. comply with the approved applicable recognized standards referenced in this code;
c. be free from defects.
2. All sanitary drainage pipe within the building must be installed with a uniform slope of at least'/4-inch per
foot(see Section 708.1). Where site conditions preclude this,a slope of per foot minimum may be
used for piping 4 inches and larger if approved by the authority having jurisdiction.

than 40 feet of 2-inch vent piping.
5. Verify that the elevator pit drain is 4 inches in size as shown on 5/P4. The 2-inch floor drain shown on Sheet
No.P1 won't allow the 50 gallons per minute flow required of it.
6. The storm water piping must be sized as follows(see Table 1101.7):
a. The 6-inch overflow storm water piping is not allowed to reduce to 3 inches in size as shown at grid
intersection B/3(see Section 1106.3).
b. If the 6-inch storm water pipe serving the primary roof drain at grid intersections C/7 is routed
horizontally,it must be sloped at a minimum 1/4-inch per foot slope.
c. If the 6-inch storm water pipe serving the primary roof drain at grid intersection E/7 is routed
horizontally,it must be sloped at a minimum 'A-inch per foot slope.

9. The water distribution system sizing must reflect the velocity limitations of the pipe material:
a. Copper systems or tubing systems using copper alloy(brass/bronze)fittings may not exceed 8 feet per
second for cold water,or 5 feet per second for hot water(see Section 610.12).
b. CPVC hot or cold water systems may not exceed 8 feet per second(see Installation Standard 20).
