13.10.050 BPA installation requirements.
A. The following requirements shall apply to the installation of BPAs.
1. All BPAs shall be of a type and model approved by the Oregon Health Division and the city of Talent.
2. An assembly installer must obtain the required plumbing permits and have the installation inspected by the city.
3. All BPAs are required to have brass or plastic threaded pipe plugs installed in all test cocks. Galvanized plugs in test cocks are not allowed.
4. Assemblies must be installed at the point of delivery of the water supply. Assemblies shall be installed before any branch in the line. BPAs shall be installed on private property immediately adjacent to the property line. Alternative locations must be approved in writing by the city prior to installation. BPAs that must be installed or are located on city rights-of-way are the responsibility of the property owner. If a BPA must be located in a city right-of-way, the following provisions will be followed:
a. A BPA required by the city may be installed upon or within any city right-of-way only if the owner proves, to the satisfaction of the city, there is no other feasible location for installing the assembly, and installing it in the right-of-way will not interfere with traffic or utilities. The city retains the right to approve the location, height, depth, enclosure, and other requisites of the assembly prior to its installation.
b. All encroachment permits required by the city to perform work in the right-of-way shall be obtained.
c. A property owner shall, at the request of the city and at the owner’s expense, relocate a BPA which encroaches upon any city right-of-way when such relocation is necessary for street, sidewalk, or utility construction or repairs for purposes of public safety.
5. The BPA shall be protected from freezing.
6. No part of a reduced pressure principle BPA shall be submerged in water or installed in a location subject to flooding. If installed in a basement or a vault, adequate drainage shall be provided.
7. Vertical installation of BPAs shall be restricted to those approved by the Oregon Health Division and must receive written city approval prior to installation.
8. The BPA shall be readily accessible with adequate room and visibility for maintenance and testing. BPAs two inches and smaller shall have a minimum of six inches’ clearance on all sides of the BPA with a maximum depth of 12 inches below ground level, unless approved in writing by the city.
9. All BPAs larger than two inches shall have a minimum clearance of 12 inches on the back side, 24 inches on the test cock side, 12 inches below the BPA and six inches above the BPA. These clearance standards apply to all assemblies installed in vaults, enclosures, and meter boxes.
10. If written permission is granted to install a BPA inside a building, the BPA shall be available for inspection during the hours of 8:00 a.m. to 5:00 p.m., Monday through Friday.
11. BPAs installed inside a building, five feet or more above the floor, shall be equipped with a rigid and permanently installed platform with railing constructed according to applicable building codes. This installation shall also meet the requirements set out by the U.S. Occupational Safety and Health Administration and the state of Oregon occupational safety and health codes.
12. Installation of a BPA in a confined space requires specific safety procedures when performing tests and maintenance.
13. Premises where interruption of water supply is important should be provided with two BPAs installed in parallel. They should be sized in such a manner that either BPA will provide the minimum water requirements while the two together will provide the necessary flow desired.
14. All facilities that require continuous uninterrupted water service, and are required to have a BPA, shall make provisions for the parallel installation of BPAs of the same type so that testing, repair and maintenance can be performed.
15. In the event a point-of-use BPA has not had the testing or repair done as required by this chapter, a premises isolation BPA or approved air gap will be required.
16. Upon completion of any BPA installation, the city shall be notified by the property or premises owner. The city will then conduct an inspection. If the installation is approved by the city, the property or premises owner shall have the BPA tested by an authorized tester. Test results shall be provided to the city by the property or premises owner or tester. The testing and repairs of all assemblies are the financial responsibility of the property and/or premises owner.
17. All BPAs must be registered with the city. Registration shall consist of the address of the BPA, date of installation, manufacturer’s name, model, type, size, serial number, and initial test report.
18. Bypass lines are prohibited. Pipe fittings which could be used for connecting bypass lines shall not be installed.
19. The BPA information nameplate and serial number must be attached to the BPA and be readily visible.
20. Pressure vacuum breaker BPAs may be utilized only in single-zone irrigation systems.
21. BPAs shall be sized to provide an adequate supply of water and pressure for the premises being served. Consult manufacturer’s specifications for specific performance data such as flow characteristics. The city is not responsible for any water pressure drop associated with the installation of BPAs.
22. Variances from these specifications will be evaluated on a case-by-case basis. Any deviations must have prior written approval of the city. [Ord. 649 § 5.]
