(A) Unless otherwise provided for in this chapter, all materials, fixtures or devices used or entering into the construction of sewer systems or parts thereof shall be submitted to the District for approval and shall conform to approved applicable standards or to other equivalent standards acceptable to the District, and shall be free of defects. All pipe, pipe fittings and fixtures shall be listed or labeled by a listing agency or shall be approved by the District when listing or labeling by a listing agency is not available.
(B) Each length of pipe and each pipe fitting, trap, material and device used in a plumbing system shall have cast, stamped or indelibly marked on it the maker’s mark or name, the weight and the quality of the product, when such marking is required by the approved standard that applies. All materials and devices used or entering into the construction of sewer systems or parts thereof shall be marked and identified in a manner satisfactory to the District.
(C) Standards listed or referenced to in this section cover materials which will conform to the requirements of this chapter, when used in accordance with the limitations imposed in this or other sections thereof and their listing. Where a standard covers material of various grades, weights, quality or configurations, there may be only a portion of the listed standard which is applicable, as determined by the District.
(D) The provisions of this chapter are not intended to prevent the use of any alternate material or method of construction provided any such alternate has first been approved and its use authorized by the General Manager.
(E) The General Manager and/or District Engineer may approve any such alternate provided he or she finds that the proposed design is satisfactory and complies with the intent of this chapter and the material offered is for the purpose intended, at least the equivalent of that prescribed in this chapter, in quality, strength, effectiveness, durability and safety or that the methods of installation proposed conform to other acceptable nationally recognized plumbing standards.
(F) The General Manager shall require that sufficient evidence or proof be submitted to substantiate any claims that may be made regarding the sufficiency of any proposed material or type of construction.
(G) Where there is insufficient evidence to substantiate claims for alternates, the General Manager and/or District Engineer may require tests, as proof of compliance, to be made by an approved testing agency at the expense of the applicant.
(H) Tests shall be made in accordance with approved standards, but in the absence of such standards, the General Manager shall specify the test procedure.
(I) The General Manager may require tests to be made or repeated if, at any time, there is reason to believe that any material or device no longer conforms to the requirements on which its approval was based.
