<br /> OWNERSHIP: ZB Construction, 10300 l Oth Avenue North, Plymouth, Minnesota 55441
<br /> SUBMITTER(S): Plumb Right, c/o Mr. Dale R. Carter, 1216 82nd Avenue North, Brooklyn Park,Minnesota

<br /> Plans Dated: Site Utilities,May 16, 2005; and Interior Plumbing, September 16, 2005
<br /> Date Received: September 23, 2005
<br /> Date Reviewed:October 6,2005
<br /> SCOPE: This review is limited to the design of this particular project only insofar as the provisions of the
<br /> Minnesota Plumbing Code, as amended, apply, and does not cover the water supply or sewerage system to which
<br /> this plumbing system is connected. The review is based upon the supposition that the data on which the design is
<br /> based are correct, and that necessary legal authority has been obtained to construct the project. The
<br /> responsibility for the design of structural features and the efficiency of equipment must be taken by the project
<br /> designer. Approval is contingent upon satisfactory disposition of any requirements included in this report.
<br /> Special care should be taken to insure that the material and installation of the plumbing system are in accordance
<br /> with the provisions of the Minnesota Plumbing Code. A copy of the approved plans and specifications should
<br /> be retained at the project location for future reference.
<br /> A set of the identified plans and specifications is being returned to Plumb Right. I
<br /> INSPECTIONS: All plumbing installations must be tested and inspected in accordance with the requirements of
<br /> the Minnesota Plumbing Code. As specified in Minnesota Rules,part 4715.2830,no plumbing work may be
<br /> covered prior to completing the required tests and inspections. Provisions must be made far applying an air test
<br /> at the time of the roughing-in inspection as outlined in Minnesota Rules,part 4715.2820, subpart 2, of the code.
<br /> A manometer test, as specified in Minnesota Rules,part 4715.2820, subpart 3, is required at the time of the
<br /> finished plumbing inspection. It is the responsibility, of the contractar/installer to notify the Minnesota
<br /> Department of Labor and Industry when an installation for a state contract job, licensed facility, or project in an
<br /> area where there is no local administrative authority is ready for an inspection and test. To schedule inspections,
<br /> contact the state plumbing standards representative for your region, or call Jim Peterson at 651/284-5889.
<br /> REQUIREMENT(S):
<br /> 1. The sanitary drainage system must be sized in accordance with Minnesota Rules,part 4715.2310, subpart 2.
<br /> The following comments pertain to the design of this drainage system:
<br /> a Once the 2-inch stack on the waste risers, PR-14 and PR-20, Sheet No. P7, connect to the horizontal
<br /> branch, the size must be increased to a minimum of 2%z-inch since a 2-inch horizontal drain can only
<br /> accommodate 6 fixture units at a slope of'/4-inch per foot(see Minnesota Rules,part 4�15.2310, subpart
<br /> 2). The horizontal branch is not sized on the submitted riser diagram. '
<br /> b. At the point where the waste riser diagram serving fixtures (PR-6,PR-4, PR-13, PR-1, nd PR-10) from
<br /> Maplewood Rooms No. 106, 107, 223, and 224, connects to the main waste branch on heet No. P1, of
<br /> the submitted plans, there appears to be 645 drainage fixture units being served by a 6-�nch drainage
<br /> pipe. Since a 6-inch horizontal drain can only accommodate 620 fixture units at a slop�of'/s-inch per
<br /> foot (see Minnesota Rules,part 47122310, subpart 2), this section of pipe appears to be undersized.
