Approval is contingent upon meeting the requirement(s) listed below.A copy of the approved plans and this report must be retained at the project location. INSPECTIONS: 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. The contractor/installer must obtain all required inspection permits from the City of Oak Park Heights Building Official. REQUIREMENT(S): 1. All plumbing must be installed in accordance with the 2015 Minnesota Plumbing Code(see Minnesota Rules,Chapter 4714). 2. Verify that the existing water supply and waste systems are sized to accommodate the added fixtures(see Minnesota Rules,Chapter 4714, Sections 610.5,610.12,and 703.0). 3. All sanitary drainage pipe within the building must be installed with a uniform slope of at least'/4-inch per foot(see Minnesota Rules, Chapter 4714, Section 708.1). Where site conditions preclude this slope,a minimum slope of''/-inch per foot minimum may be utilized for piping 4 inches and larger if approved by the authority having jurisdiction. 4. Changes in direction in drainage piping must be made by appropriate use of wyes and bends(see Minnesota Rules,Chapter 4714, Section 706.0). Sanitary tees are not allowed where the direction of flow changes from either vertical to horizontal or horizontal to horizontal. 5. All sinks, except for lavatories,must be provided with 2-inch minimum vertical fixture drains(see Minnesota Rules,Chapter 4714,Tables 702.1 and 703.2). 6. Fixture drains must connect to vertical sanitary drains with tee connections rather than the wye connections indicated in the waste and vent riser diagram(see Minnesota Rules, Chapter 4714, Sections 905.5 and 1002.4). This information can be provided to you in alternative formats(Braille,large print or audio).

A common vent may serve two fixtures if each fixture drain connects independently to a vertical drain through an approved double fixture fitting. Double sanitary tees are not permitted. Otherwise,individual vent pipes must be provided on the dedicated fixture branches(see Minnesota Rules,Chapter 4714, Sections 704.2 and 905.6). 8. Verify that the waste and vent piping is sized as follows(see Minnesota Rules,Chapter 4714,Table 703.2): a. The sanitary branch serving the hub outlet and sinks S-2 and S-4 must be at least 2-1/2 inches in size. A 2-inch horizontal sanitary branch can serve a maximum of 8 drainage fixture units. b. The horizontal 1-1/2 inch vent serving a treatment sink is limited to 20 feet in length. Any additional piping must be at least 2 inches in size. c. The horizontal 2-inch vent serving the water closet in Room 102 is limited to 20 feet in length.Any additional piping must be at least 2-'/2 inches in size. The plans incorrectly show 47 feet of 2-inch horizontal vent. d. Any vent serving a 6-unit trap must be at least 2 inches in size. 9. Verify that the vacuum pump discharges indirectly to an approved receptor(see Minnesota Rules,Chapter 4714, Sections 805.1 and 807.1).The plans incorrectly appear to show the vacuum pump discharge connecting directly to the sanitary system. 10. The plans indicate that a plaster trap will be installed at the lab sink. Plaster traps are approved for special conditions under Minnesota Rules,Chapter 4714, Section 1004.1.Verify that the plaster trap complies with the following requirements: a. A plaster trap must be listed by an independent third party to a nationally recognized standard for the proposed application(see Minnesota Rules,Chapter 4714, Section 301.1). b. A plaster trap must be installed in accordance with the manufacturer's installation instruction and Minnesota Rules,Chapter 4714,Section 1004.1. c.

Copper tubing with mechanical joints: per administrative authority requirements. e. PEX pipe: 32 inches for 1-inch and smaller,4 feet for larger sizes. Aspen Dental Interior Finish Plumbing Plan No.PLB 1706-00374 Page 3 July 24,2017 13. Discharge from a relief valve into a water heater pan is prohibited(see Minnesota Rules,Chapter 4714, Section 507.5). The discharge from a relief valve must terminate to a safe place of disposal or within 18 inches of the floor. Detail 4/P3.0 incorrectly shows the water heater relief valve discharging to the drain pan. 14. Water heaters must be accessible with sufficient clearance for maintenance and repair.Unlisted water heaters must have 12 inches minimum clearance on all sides(see Minnesota Rules,Chapter 4714, Sections 507.26 and 504.3.2).Water heaters must be provided with a water-tight corrosion-resistant drainage pan when located where damage may be caused by leaking(see Minnesota Rules, Chapter 4714, Section 507.4).A 3/4- inch minimum drainage outlet must extend from the drainage pan to an approved location. 15. Appliances,devices,or apparatus such as stills,sterilizers,and similar equipment requiring water and waste and used for sterile materials must be drained through an air gap(see Minnesota Rules, Chapter 4714, Section 806.1). 16. Verify that the potable water supply to the eyewash/drench hose is protected against contamination through the use of a high-hazard backflow preventer that complies with Minnesota Rules,Chapter 4714,Table 603.2. The integral backflow preventers available for this product are insufficient for this application. An atmospheric vacuum breaker,a double-check valve assembly,and a double-check valve with intermediate atmospheric vent are not acceptable for this installation. An ASSE 1020 pressure vacuum breaker, or an ASSE 1056 spill-proof vacuum breaker,installed 12 inches above the spill level and in a location where it will not be subjected to back pressure are acceptable for this installation. An ASSE 1013 reduced pressure zone backflow preventer would also be acceptable. 17. If a potable water connection is provided for the dental vacuum pump, it must be protected from backflow by an air gap,an atmospheric vacuum breaker,a spill-proof vacuum breaker,or a reduced pressure zone backflow preventer(see Minnesota Rules, Chapter 4714, Section 603.5.17). The atmospheric vacuum breaker must be installed downstream of the last control valve and at least 6 inches above all piping and the flood level. A spill-proof vacuum breaker must be installed at least 12 inches above all piping and the flood level. 18. The potable water connections to the hand-held sprayers at the treatment sinks,lab sink, and sterile sink (Fixtures S-1, S-2, S-3,and S-4)must be protected against contamination through the use of a high-hazard backflow preventer(see Minnesota Rules,Chapter 4714, Section 603.2). 19. Water supply connections to fixtures or equipment which have inlets below the spill line must be provided with an approved backflow preventer(see Minnesota Rules, Chapter 4714, Section 602.3). The potable water connections to the trap primers must be protected against contamination through the use of high-hazard backflow preventers.A double check valve assembly and double check valve with intermediate atmospheric vent are not approved for this application. 20. The potable water connection to the model trimmer must be provided with a code compliant air gap or an approved high-hazard backflow preventer(see Minnesota Rules, Chapter 4714, Section 602.3). The specified ASSE 1012 double check valve with intermediate atmospheric vent is not sufficient for this application. Aspen Dental Interior Finish Plumbing Plan No. PLB 1706-00374 Page 4 July 24,2017 21. Each horizontal drain branch,including floor drain branches,must be provided with a cleanout at its upper terminal with the following exceptions(see Minnesota Rules,Chapter 4714, Section 707.4): a. A cleanout may be omitted if the drain branch line is less than five feet,unless the drain serves sinks or urinals. b. A cleanout may be omitted on a drain that is 72 degrees or less from the vertical. 22. PVC drain,waste,and vent systems shall comply with Minnesota Rules,Chapter 4714,Table 701.1, Section 705.7,and Installation Standard 9: a. Joints must be mechanical or push-on utilizing an elastomeric seal,or solvent welded using ASTM F656 purple primer and ASTM D2564 solvent cement. Schedule 80 pipe may be threaded. b. Above-ground horizontal pipes must be supported at each horizontal branch connection.Restraint fittings or a minimum 24-inch offset using 45-degree fittings should be provided every 30 feet. Expansion joints installed per the manufacturer's instructions may be installed in vertical runs exceeding 30 feet. 23. Cross-link polyethylene(PEX)water service or water distribution systems must meet Minnesota Rules, Chapter 4714, Section 605.10 and Table 604.1: a. The tubing must comply with ASTM F876,ASTM F877,or CSA B137.5. AWWA C904 PEX may be used for cold water applications only. b. ASTM F876 tubing must be marked with the standard of the fittings to be utilized. c. The fittings must be marked with ASSE 1061,ASTM F877,ASTM F1807,ASTM F1960,ASTM F1961,ASTM F2080,ASTM F2159,ASTM F2735,or CSA B137.5. 24. The plumbing system must be tested in accordance with Minnesota Rules,Chapter 4714, Sections 609.4 and 712.0.The potable water system must be disinfected per Minnesota Rules,Chapter 4714, Section 609.9. NOTES: I. The scope of this project consists of the tenant finish for a dental office. The plumbing includes two tank- type water closets,two lavatories,seven treatment sinks,a sterile sink,a lab sink,a breakroom sink,three floor drains,a hub outlet drain,a bottle filling station,two eyewash/drench hose units,a water heater,and potable water connections to trap primers and dental equipment. The fixtures connect to the existing sanitary sewer and to the existing water distribution system. 2. This facility is served by existing municipal sewer and existing municipal water services. The site utilities and shell building plumbing appear to have been approved as Plan No. PLB 1705-00315. 3. The dental equipment supplier must be licensed as a master plumber by the State of Minnesota in order to install plumbing piping, fixtures, and appurtenances. The note on Sheet No.P 1.0 seems like it might be granting too many plumbing installation responsibilities to a dental equipment supplier that may not be properly licensed for such work. 4.
