This appendix provides a general procedure for sizing a water supply system. Rapidly and efficiently calculate project parameters. Velocities shall not exceed 10 feet per second (ft/s) (3 m/s), except as otherwise approved by the Authority Having Jurisdiction. Notice: Where the highest group of fixtures contains flushometer valves, the residual pressure for the group shall be not less than 15 pounds force per square inch (psi) (103 kPa). The result is the estimated supply demand of the building supply.

Where a meter is to be installed, the friction loss in the meter for the estimated maximum demand should also be subtracted from the service pressure to determine the pressure loss available for friction loss in the supply pipes. Determine the elevation of the highest fixture or group of fixtures above the water (street) main. Because of the variable conditions encountered, it is impractical to lay down definite detailed rules of procedure for determining the sizes of water supply pipes in an appendix, which shall necessarily be limited in length. © 2020 American Water. Duty Extended Low 1 ½” T160 4 to 200 GPM 160 GPM 2.5 GPM 2” T200 4 ... • Capture data from a specific water meter • Log water usage per period of time • Sense flow, record and display data • Provides a snapshot of water usage Use one-half the allowances for recessed threaded fittings or streamlined solder fittings. Capture and share institutional knowledge within your team and company. Water emergencies don't keep business hours. Decide what is the desirable minimum residual pressure that shall be maintained at the highest fixture in the supply system. For SI units: 1 inch = 25 mm, 1 gallon per minute = 0.06 L/s, 1 pound-force per square inch = 6.8947 kPa, 1 foot = 304.8 mm, 1 foot per second = 0.3048 m/s, For Sl units: 1 gallon per minute = 0.06 L/s, 1 pound-force per square foot = 6.8947 kPa, Chapter 4 Plumbing Fixtures and Fixture Fittings, Chapter 13 Health Care Facilities and Medical Gas and Medical Vacuum Systems, Chapter 15 Alternate Water Sources for Nonpotable Applications, Chapter 16 Nonpotable Rainwater Catchment Systems, Chapter 16A Non-Potable Water Reuse Systems, Appendix A Recommended Rules for Sizing the Water Supply System, A106.0 Size of Principal Branches and Risers, Appendix B Explanatory Notes on Combination Waste and Vent Systems, Appendix D Sizing Storm Water Drainage Systems, Appendix E Manufactured/Mobile Home Parks and Recreational Vehicle Parks, Appendix F Firefighter Breathing Air Replenishment Systems, Appendix H Private Sewage Disposal Systems, Appendix I Installation Standard for PEX Tubing Systems for Hot-And Cold-Water Distribution, Appendix J Combination of Indoor and Outdoor Combustion and Ventilation Opening Design, Appendix K Potable Rainwater Catchment Systems, Adopt Entire Chapter as amended (amended sections listed below), Adopt only those sections that are listed below, Bathtub or Combination Bath/Shower (fill), Clinical Flushometer Valve with or without faucet, Water Closet, greater than 1.6 GPF Gravity Tank, Water Closet, greater than 1.6 GPF Flushometer Valve. All feedback is helpful! New customers can start their services online. Your selected jurisdiction and code year has limited Surface critical code sections based on your project inputs. These inputs help surface the applicable codes and requirements. The result is the loss in static pressure in psi (kPa). To use less water, it’s helpful to know how much you’re using and where. Subtract the sum of loss in static pressure and the residual pressure to be maintained at the highest fixture from the average minimum daily service pressure. Friction losses for disk-type meters shall be permitted to be obtained from Chart A. Unpack the code through illustrations and descriptions. Projects allow you to save customized inputs about your building. This new tool allows you to input water use information specific to your household and offers tips on where you can save water and energy based on that data. If you are new to the waterworks or metering industry, meter and meter connection sizing can be confusing. Friction-loss data is capable of being obtained from most manufacturers of water meters. Leverage the most sophisticated code compliance platform. This new tool allows you to input water use information specific to your household and offers tips on where you can save water and energy based on that data.
