B82 J • APPENDIX A � 4 RULES FOR SIZING THE WATER SUPPLY SYSTEM The following is the required order of procedure for sizing the water supply system. A3.1 Decide what is the desirable minimum pressure that should be maintained at the highest fixture in the supply system. If the highest group of fixtures contains flush valves, the pressure for the group shall not be less than fifteen (15) psi . For flush-tank supplies, the available pressure shall be not less than eight (8) psi . A4.3 Chart A-5 shall be used for ferrous pipe with only the most favorable water supply as regards corrosion and caking. If the water is hard or corrosive, Charts A-6 or A-7 shall be applicable. For extremely hard water, additional allowances for the reduction of capacity of hot water lines in service shall be made. A5.1 The required size of branches and risers shall be obtained in the same manner as the building supply by obtaining the demand load on each branch or riser and using the permissible friction loss computed in Section A3 A5.2 Fixture branches to the building supply, if they are sized for the same permissible friction loss per one hundred (100) feet of pipe as the branches and risers to the highest level in the building, may lead to in- adequate water supply to the upper floor of a building. This shall be con- trolled by: (1) Selecting the sizes of pipe for the different branches so that the total friction loss in each lower branch is approximately equal to the total loss in the riser, including both friction loss and loss in static pressure; (2) by throttling each such branch by means of a valve until the preceding balance is obtained; (3) by increasing the size of the building supply and risers above the minimum required to meet the maximum permissible friction loss. A6.1 A velocity greater than fifteen (15) feet per second in the main risers, or principal branches shall not be employed, as objectionable line noise is likely to result A6.2 If a pressure reducing valve is used in the building supply, the developed length of supply piping and the permissible friction loss shall be computed from the building side of the valve. 883 - 1 APPENDIX 8 No Requirements APPENDIX C No Requirements 884 APPENDIX E ..

B87 z McMAHAry City of Fort Worth, Texas Mayor Council / Communication � � / �/ LINE J �'ll ayor and Co IL�ncil Co m�Vnication GRAHAM DATE REFERENCE SUBJECT: PAGk NUMBER BUILDING 12/21/70 G-1675 Recommended Plumbing Code 2 of 2 On September 29, 1968, the City Council appointed a Plumbing Code Review Com- mittee to review the national model plumbing codes and to recommend one as the model code for the City of Fort Worth. After studying the existing model codes, the Committee agreed to recommend the Uniform Plumbing Code, promul- gated by the International Conference of Building Officials, as the model for the City of Fort Worth Plumbing Code. The proposed Plumbing Code represents the work of thirty meetings conducted by the Plumbing Code Review Committee for periods lasting from several hours to all day in deliberation of various aspects of the Code. In addition, many informal meetings and discussions were held. Nature of Proposed Code The proposed new Ordinance, which is the first major overhaul of the Plumbing Code since 1952, is essentially the 1970 Uniform Plumbing Code. Only those changes and modifications necessary to relate the code more appropriately to local conditions are recommended. Certain of the changes, typified by the Venting Provisions, permit a much simpler and more economical procedure than that required by the Uniform plumb- ing Code. The bulk of the proposed Code provisions are already in current local practice, so that the change in regulatory effect will be minimal. However, the body of the Code will be completely revised, reorganized and made far simpler to use and interpret. The proposed Ordinance will require plans to be submitted on all projects where more than forty plumbing fixtures are involved and that plans with more than one hundred fifty fixtures have the Seal of a Registered Professional Engineer. The proposed Ordinance acknowledges and accepts new materials and methods and separates from the Plumbing'Code those requirements which will now come under the jurisdiction of the proposed Mechanical Code. While some increased construction costs can be expected in some areas, such expense will be more than offset by changes in material and construction re- quirements made possible by the proposed Ordinance. Under the proposed Ordi- nance, the $.75 per fixture permit fee will be increased to $1.00 per fixture. The proposed Ordinance requires the Plumbing Code Board .to review the annual amendments to the Uniform Plumbing Code adopted by the International Confer- ence of Building Officials, as well as other suggested amendments. Subsegoently, the Board will submit to the City Council yearly its recommendations for re- visions to the Plumbing Code of the City of Fort Worth.
