Current through Register Vol. 50, No. 11, November 20, 2024
A. General Testing Requirements. The state health officer and/or the local plumbing official may also require tests to be conducted prior to occupancy to assure that the proposed design is satisfactory and complies with the intent of this code. Such tests shall be made in accordance with approved standards, but in the absence of such standards, the state health officer and/or the local plumbing official shall specify the test procedure(s). In general, such tests shall indicate that all fixtures properly discharge when flushed simultaneously with not less than 1-inch (25.4mm) of water seal left in the trap after testing and that there is no evidence of sewer gas passing through the trap seal.B. Roughing-In. The roughing-in test shall be as provided for in other Chapters of this code.C. Tests and Inspection of the Single Stack Discharge and Ventilating Pipe System or any other Single Stack Plumbing System. When a single stack discharge and ventilating pipe system (a specific type of alternate designed plumbing system) or any other single stack plumbing system has been approved by the state health officer under the requirements of this Chapter, the following tests/inspections shall be performed. 1. Performance Test Required. In any building in which fixtures or appliances, other than those specifically provided for in Table 1811.D.5.5A of this code, are to be installed or in existing buildings in which the single stack discharge and ventilating pipe system or any other single stack plumbing system exists and additional fixtures are to be added, the plumbing official shall require and supervise a performance test as hereafter provided.2. Application and Restrictions. When required in new construction, the system shall successfully pass the test before the building is permitted to be occupied. In existing buildings where piping is added for additional fixtures or appliances, such new piping shall not be placed in service until the performance test is approved. Should the system fail to pass the test, the new construction shall be modified as the plumbing official may direct, or the system shall be reconstructed to meet the requirements of other Chapters of this code, or the added fixtures and appliances shall be removed and all waste and vent pipes permanently closed so as to form no dead ends and all wall and other openings shall be put back in their original or finished condition. a. Exception. Central washing facilities connected separately to the building drain or sewer in an installation that is otherwise constructed in accordance with other Chapters of this code are exempt from the performance testing prescribed by this Section.3. Performance Test. Every trap shall retain not less than 1-inch (25.4 mm) of seal when subjected to the appropriate discharge tests given below. These tests are designed to simulate the probable worst conditions in practice. Each test should be repeated three times, the trap being recharged before each test, and the maximum loss of seal in any one test, measured by a dip stick, shall be taken as the significant result. The number of fixtures to be discharged simultaneously when investigating the effect of the flow of water down the stack depends on the number of fixtures and on the frequency with which they are used. The number of fixtures to be discharged simultaneously is given in Table 1811.D.11 of this code.4. Test for Self-Siphonage. To test for the effect of self-siphonage, the waste fixture shall be filled to overflowing level and discharged in the normal way. The seal remaining in the trap shall be measured when the discharge has finished. This test is most important for wash basins, but it is not applicable for water closets which shall be flushed in the normal manner.La. Admin. Code tit. 51, § XIV-1205
