SEC. 1006-GRAVITY SUPPLY TANKS Gravity tanks for potable water shall be tightly covered, and have not less than a sixteen (16) square inch overflow screened with copper screen having not less than fourteen (14) nor more than eighteen (18) openings per linear inch. SEC. 1007 - WATER PRESSURE, PRESSURE REGULATORS AND PRESSURE RELIEF VALVES (a) INADEQUATE WATER PRESSURE. Whenever the water pressure in the main or other source of supply will not provide a water pressure of at least fifteen (15) pounds per square inch, after allowing for friction and other pressure losses, a tank and pump or other means which will provide said fifteen (15) pound pressure shall be installed. (b) EXCESSIVE WATER PRESSURE - Where local water pressure is in excess of eighty (80) pounds per square inch, an approved type pressure regulator preceded by an adequate strainer shall be installed and the pressure reduced to eighty (80) pounds per square inch or less. For potable water services up to and including 1 1/Z" regulators, provision shall be made to prevent pressure on the building side of the regulator from exceeding main supply pressure. Approved regulators with integral by-passes are acceptable. Each such regulator and strainer shall be accessibly located and shall have the strainer readily accessible for cleaning without removing the regulator or strainer body or disconnecting the supply piping. All pipe size determinations shall be based on eighty (80) percent of the reduced pressure.

Each such combination temperature and pressure relief valve shall be provided with a drain as required in Subsection (e) of this section. Temperature relief setting shall not exceed 2100F. SEC. 1008- No Requirements. SEC. 1009- SIZE OF POTABLE WATER PIPING (a) The size of each water meter and each potable water supply pipe from the meter or other source of supply to the fixture supply branches, risers, fixtures, connections, outlets or other uses shall be based on the total demand and shall be determined according to the methods and procedures outline in this section. (b) Whenever a water filter, water softener or similar water treating device, backflow prevention device or similar device is installed in any water supply line, the pressure loss through such devices must be included in the pressure loss calculations of the system, and the water supply pipe and meter shall be adequately sized to provide for any such pressure loss. No water filter, water softener, backflow prevention device or similar device regulated by this code shall be installed in any potable water supply piping when the diameter of the inlet or outlet of any such device or its connecting piping is less than the diameter of such water supply piping, or when the installation of such device produces an excessive pressure drop in any such water supply piping. All such devices shall be of a type approved by the Adminis- trative Authority and shall be tested for flow rating and pressure loss by an approved laboratory or recognized testing agency to standards consistent with the intent of this chapter. The maximum rated flow and the pressure loss shall be stamped legibly on the device or on a metal label, permanently attached to the device, and shall be in the following form: MAXIMUM PRESSURE DROP Flow Pressure Drop Gallons per minute Pounds per square inch 5 -- 10 -- 15 -- NOTE; The final figure in the flow rate column shall be the maximum rated flow or capacity of the device. (c) The quantity of water required to be supplied to every plumbing fixture shall be represented by fixture units, as shown in Table 10-1. Equivalent fixture values shown in Table 10-1 include both hot and cold water demand. (d) Where the maximum length of supply piping is two hundred (200) feet or less, each water piping system of fifty (50) fixture units or less shall be sized in accordance with the values set forth in Table 10-2 of this section. Other systems within the range of Table 10-2 may be sized from that table or by the method set forth in sub-section (3) of this section. (e) Except as provided in subsection (d) of this section, the size of each water piping system shall be determined in accordance with the procedure set forth in Appendix A of this code (Recommended Rules for Sizing the Water Supply System). (f) Except where the type of pipe used and the water characteristics are such that no decrease in capacity due to length of service (age of system) may be expected, all friction loss data shall be obtained from the "Fairly Rough" or "Rough" charts in Appendix A of this code. Friction or pressure losses in water meters, valve and fittings shall be obtained from the same sources. Pressure losses through water treating equipment, backflow prevention devices or other flow restricting devices shall be computed as required by subsection (b) of this section. (g) On any proposed water piping installation sized pursuant to Table 10-2 the following conditions shall be determined: (1) Total number of fixture units as determined from the table of Equivalent Fixture Units (Table 10-1) for the fixtures to be installed. (2) Developed length of supply pipe from meter to most remote outlet. (3) Difference in elevation between the meter or other source of supply and the highest fixture or outlet. (4) Pressure in the street main or other source of supply at the locality where the installation is to be made. Calculations shall be based on not to exceed one hundred (100) p.s.i. pressure in the system. (5) In localities where there is a wide fluctuation of pressure in the main throughout the day, the water piping systems shall be designed on the basis of the minimum pressure available. (h) SIZE OF METER AND BUILDING SUPPLY PIPE USING TABLE 10-2. Knowing the available pressure at the water meter or other source of supply, and after subtracting one half (1/Z) pound per square inch pressure for each foot of difference in elevation between such source of supply and the highest water supply outlet in the building or on the premises,use the "Pressure Range" group within which this pressure will fall. Select the "length" column which is equal to or longer than the required length. Follow down the column to a fixture unit value equal to or greater than the total number of fixture units required by the installation. Having located the proper fixture unit value for the required length, sizes of meter and building supply pipe will be found in the two left-hand columns. No building supply pipe shall be less than three-quarter (3/4) inch in diameter. (i) SIZE OF BRANCHES. The size of each branch shall be determined by the number of fixture units to be served by that branch, following the methods outlined in subsection (h) of this section. 0) SIZING FOR FLUSHOMETER Valves. Branches and mains serving water closet or similar flushometer valves may be sized from Table 10-Z when the following values are assigned to each flushometer valve beginning with the most remote valve on each branch. law For the first flushometer valve .... 40 fixture units For the second flushometer valve ...30 fixture units For the third flushometer valve ... 20 fixture units For the fourth flushometer valve ...15 fixture units For the fifth flushometer valve ... 10 fixture units Five fixture unit flushometer valves may be computed at half the above values assigned, but in no case less than five fixture units. After the fifth valve on any branch or main, subsequent fixture unit loadings may be computed using the values given in Table 10-1 of this chapter. Piping supplying a flushometer valve shall not be less in size than the valve inlet. NOTE: Any system using flushometer valves may be sized by the procedures set forth in subsection (e) of this section. (k) SIZING SYSTEMS WITH HOT WATER PIPING. In sizing water piping system having a total demand of fifty (50) fixture units or less, the greatest developed length of the cold water supply piping may be used (from table 10-2) and the length of the hot water piping ignored when the hot water piping friction loss is compensated for by the following method: 1) Compute the total hot water fixture unit demand,using those values given in Table 10-1 for the combined hot and cold water use. (2) Assign the total demand computed as required in (1) above, as the fixture unit demand at the hot water heater inlet. (3) Starting at the most remote outlet on the cold water piping and working back toward the water meter, compute the pipe sizing for the system from the column originally selected in Table 10-2, using the fixture unit values given in Table 10-1, and adding in the fixture unit demand of the hot water heater supply inlet as computed in (1) above, at the point where it occurs. The final size of the cold water branch or main need not exceed the originally established size of the building supply. (1) Except as provided in subsection (k), water piping systems may be designed by taking the total length of the supply piping from the source of cold water supply through the water heater, to the most remote hot water outlet and assessing flow values of seventy-five (75) per cent of the combined hot and cold water demand as given in Table 10-1, to the piping supplying either hot or cold water to those fixtures served by both. Piping serving water heaters shall be sized to deliver the above required hot water demand, plus all required cold water demands, but in no case need the piping be larger in size than that required by Table 10-2 for the total building supply. (m) EXCEPTIONS. The provisions of this section relative to size of water piping need not apply to the following: (1) Water supply piping systems designed in accordance with recognized engine ring procedures acceptable to the Ad- ministrative Authority. (2) Alteration of or minor additions to existing installa- tions,provided the Administrative Authority finds that there will be a reasonably adequate supply of water for all fixtures. (3) Replacement of existing fixtures or appliances. (4) Piping which is part of fixture or equipment. (5) Unusual conditions where, in the judgment of the Administrative Authority, a reasonably adequate supply of water is provided. (6) Non-potable water lines as defined in subsection (o) of Section 1003..

All natural gas regulations and tables are based on the use of gas having a specific gravity of sixty-five hundredths (.65), supplied at six (6) to eight (8) inches water column pressure at the outlet of the meter. For undiluted liquefied petroleum gas, gas piping may be sized for 2500 BTU per cu. ft. at eleven (11) inches water column and specific gravity of one and fifty-two hundredths (1.52). NOTE : Where gas of a different specific gravity is to be delivered the serving gas supplier should be contracted for specific gravity conversion factors to use in sizing piping systems from the pipe sizing tables in this chapter. (b) The hourly volume of gas required at each piping outlet shall be taken as not less than the maximum hourly rating, as specified by the manufacturer of the appliance or appliances to be connected to each such outlet. (c) Where the gas appliances to be installed have not been definitely specified, Table lZ-1 may be used as a reference to estimate requirements of typical appliances. To obtain the cubic-feet-per-hour of gas required, divide the BTU input of appliances by the average BTU heating value per cubic foot of the gas. The average BTU per cubic foot of the gas in the area of the installation may be obtained from the serving gas supplier. (d) The size of the supply piping outlet for any gas appliance shall be not less than one-half (1/2) inch. The minimum size of any piping outlet for a freestanding gas range or a mobile home shall be three-quarter (3/4) inch. SEC. 1219- REQUIRED GAS PIPING SIZE (a) Where the maximum demand does not exceed two hundred fifty (250) cubic feet per hour and the maximum length of piping between the meter and the most distant outlet is not over two hundred fifty (250) feet, the size of each section and each outlet of any system of gas piping shall be determined by means of Table 12-2. Other systems within the range of Table 12-2 may be sized from that table or by means of the methods set forth in subsection (c) of this section. (b) To determine the size of each section of pipe in any system within the range of Table 12-2, proceed as follows: (1) Measure the length of the pipe from the gas meter location to the most remote outlet on the system. (Z) In Table 12-2 select the column showing that distance, or the next longer distance, if the table does not give the exact length. (3) Starting at the most remote outlet, find in the vertical column just selected, the gas demand for that outlet. If the exact figure of demand is not shown choose the next larger figure below in the column. r.o � low ,.. (4) Opposite this demand figure, in the first column at the left in Table 12-2 will be found the correct size of pipe. (5) Using this same vertical column, proceed in a similar manner for each section of pipe serving this outlet. For each section of pipe determine the total gas demand supplied by that section. Where gas piping sections serve both heating and cooling equipment and the installation prevents both units from operating simultaneously, only the larger of the two demand loads need be used in sizing these sections. (6) Size each section of branch piping not previously sized by measuring the distance from the gas meter location to the most removed outlet in that branch and follow the procedures of steps 2,3, 4 and 5 above. NOTE: Size branch piping in the order of their distance from the meter location, beginning with the most distant outlet not previously sized. (c) For conditions other than those covered by subsection (a) of this section, such as longer runs or greater gas demands, the size of each gas piping system shall be determined by standard engineering methods acceptable to the Administrative Authority and each such system shall be so designed that the total pressure drop between the meter or other point of supply and any outlet when full demand is being supplied to all outets, will at no time exceed five-tenths (0.5) inches water column pressure. (d) Where the gas pressure may be higher than fourteen (14) inches or lower than six (6) inches of water column, or when diversity demand factors are used, the design, pipe, sizing, materials, location and use of such systems first shall be approved by the Administrative Authority and the serving gas supplier supplying the gas. Systems using undiluted liquefied petroleum gas may be sized using Table 12-4 for eleven (11) inches water column and in accordance with the provisions of Sub-section (a). SEC. 1220- MEDIUM PRESSURE GAS PIPING SYSTEMS (a) Definitions Medium pressure - pressure over fourteen (14) inches of water column but not to exceed five (5) psig. Second State Pressure - used in liquefied petroleum gas systems. Pressure over fourteen (14) inches of water column but not to exceed twenty (20) psig. (b) Approval of both the Administrative Authority and the Gas Utility shall be obtained before any medium pressure gas piping system is installed. (c) Except as set forth herein, the requirements of this chapter shall apply to medium pressure gas piping systems. (d) Approved regulators shall be installed on medium pressure gas piping systems, in approved locations either outside the building or when vented to the outside, in non-hazardous, well ventilated interior locations, and shall be readily accessible for servicing. Each regulator shall have a separate vent to the outside. EXCEPTIONS: Pounds to inches water column regulators installed at the appliance location and equipped with limiting orifices capable of releasing not more than 5 cubic feet of gas per hour, when supplied with 5 psi of pressure, need not be vented to an outside location when such appliance regulators have been approved by the Administrative Authority and the serving gas supplier. These appliance regulators, when installed at each appliance location, shall: (1) Be connected to the same piping material used to pipe the structure. A listed gas connector may be used to attach the low pressure piping downstream of the regulator to the appliance manifold. (2) Have an approved gas valve in the supply line upstream of the pounds to inches water regulator. (3) Be accessible. (4) Have the upstream pressure identified. Such identifi- cation shall be a metal tag permanently attached to the regulator and state: Warning - if 2 to 5 pounds natural gas pressure. DO NOT REMOVE. (5) Be installed in a location that communicates with a ventilated area. 11 f (e) An approved gas valve shall be installed immediately preceding each regula. All regulators that may be subjected to mechanical damage shall be substantially protected to the satisfaction of the Administrative Authority. (f) Tables 12-6 and 12-7 may be used to size natural gas piping system carrying three (3) or five (5) psig gas. The procedure to determine the size of each section of the system is similar to that contained in Sec. 1219 o' this Code using the pipe length from the meter to the most remote regulator on the medium pressure system and sizing the downstream low pressure piping from Table 12-2. (g) Table 12-8 may be used to size undiluted liquefied petroleum gas piping systems carrying 10 psig gas. The procedure to determine the size of each section of the system is similar to Sec. 1219 of this code using the pipe length from the first stage or tank regulator to the most remote regulator in the second state system. Low pressure piping to be sized from Table 12-4. (h) Buried medium pressure gas piping shall be protected from corrosion as required by Chapter 12 and shall have a minimum earth cover of eighteen (18) inches. Such piping shall be covered with at least six (6) inches of hand placed selected backfill devoid of rocks, building materials or other matter that may damage the pipe or wrapping. a N ^ N O N 1 N N N N CO 1 C Q h •O ro .pp C4 N W .O ^ NO r) •O P CO j C ^ CN CV O jS N N o 0 j E OQD Cno 4 N W 'Wyt A h O c G O c u CV 3 CL N g W O •O N CO N O� C, h N 00i) O 7 C4 5wCL , O ^ O '- N ^ cr Q CO N C- O n J N S ^ Cr Q O, v u o-po ^ C E M N CV N O N N X ^ ^ C`A N N 0O NOD W ^ C) N CV Q N CO0.

APPENDICES This part is intended to supplement the provisions of the In- stallation Requirements of this code. The definitions set forth in Chapter 1 are also applicable to the provisions of these Appendices. APPENDIX A RECOMMENDED RULES FOR SIZING THE WATER SUPPLY SYSTEM Because of the variable conditions encountered it is imprac- tical to lay down definite detailed rules of procedure for deter- mining the sizes of water supply pipes in an appendix which must necessarily be limited in length. For a more adequate under- standing of the problems involved, the reader is referred to Water-Distributing Systems for Buildings, Report BMS 79 of the National Bureau of Standards; and Plumbing Manual, Report BMS 66, also published by the National Bureau of Standards. The following is a suggested order of procedure for sizing the water supply system. Al PRELIMINARY INFORMATION A1.1 Obtain the necessary information regarding the minimum daily service pressure in the area where the building is to be located. A1.2 If the building supply is to be metered, obtain informa- tion regarding friction loss relative to the rate of flow for meters in the range of sizes likely to be used. Friction-loss data can be obtained from most manufacturers of water meters. Friction losses for disk type meters may be obtained from Chart A-1. A1.3 Obtain all available local information regarding the use of different kinds of pipe with respect both to durability and to decrease in capacity with length of service in the particular water supply. A2 DEMAND LOAD A2.1 Estimate the supply demand for the building main and the principal branches and risers of the system by totaling the fixture units on each, Table A-2, and then by reading the corresponding ordinate from Chart A-21 or A-3, whichever is applicable. A2.2 Estimate continuous-supply demands in gallons per minute for lawn sprinklers, air conditioners, etc., and add the sum to the total demand for fixtures. The result is the estimated supply demand for the building supply. A3 PERMISSIBLE FRICTION LOSS 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 should not be less than fifteen (15) psi.For flush-tank supplies, the available pressure may be not less than eight (8) psi. J�� CHART A•1 Friction tones for Disk Type Water Meters 20 16 i 1 ti 67 �6 3 I 2ry i 6 � i 1 5 61 0910 20 Fla.-(;dka s per Mim to Tr_2 680 800 1J00 A3.2 Determine the elevation of the highest fixture or group of fixtures above the water (street) main. Multiply this difference in elevation by forth-three hundredths (0.43). The result is the loss in static pressure in psi (pounds per square inch). AM Subtract the sum of loss in static pressure and the pressure to be maintained at the highest fixture from the average minimum daily service pressure. The result will be the pressure available for friction loss in the supply pipes, if no water meter is used. If 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 s€,pply pipes. A3.4 Determine the developed length of pipe from the water (street) main to the highest fixture. If close estimates are desired, compute with the aid of Table A-3 the equivalent length of pipe for all fittings in the line from the water (street) main to the highest fixture and add the sum to the development length. The pressure available for friction loss in pounds per square inch, divided by the developed lengths of pipe from the water (street) main to the highest fixture, times one hundred (100), will be the average permissible friction loss per one hundred (100) foot length of pipe. A4 SIZE OF BUILDING SUPPLY A4.1 Knowing the permissible friction loss per one hundred (100) feet of pipe and the total demand, the diameter of the building supply pipe may be obtained from Charts A-4, A-5, A-6 or A-7, whichever is applicable. The diameter of pipe on or next above the coordinate point corresponding to the estimated total demand and the permissible friction loss will be the size needed up to the first branch from the building supply pipe. A4.2 If copper tubing or brass pipe is to be used from the supply piping, and if the character of the water is such that only slight char, =»s in the hydraulic characteristics may be expected, Chart A-4 way be used. A4.3 Chart A-5 should 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 will be applicable. For extremely hard water, it will be advisable to make additional allowances for the reduction of capacity of hot water lines in service. A5 SIZE OF PRINCIPAL BRANCHES AND RISERS A5.1 The required size of branches and risers may be obtained in the same manner as the building supply by obtaining the demand load on each branch or riser and using ?'-e permissible friction loss computed in Section A3. A5.2 Fixture branches to the building supply, if they are sized for the same permissible friction 1. "s per one hundred (100) feet of pipe as the branches and risers to the highest level in the building, may lead to inadequate water supply to the upper floor of a building. This may be controlled by: (1) Selecting the sizes of pipe for the efferent 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 GENERAL A6.1 In general, a velocity gr,2ater than fifteen (15) feet per second in the main risers, or principal branches should 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 should be computed from the building side of the valve. A6.3 The allowances in Table A-3 for fittings are based on non-recessed threaded fittings. For recessed threaded fittings and streamlined soldered fittings, one-half (1/2) the allowances given in the table will be ample. A7 EXAMPLE A7.1 Assume an office building of four (4) stories and basement; pressure on the building side of the pressure-reducing valve of fifty-five (55) psi; an elevation of highest fixture above the pressure-reducing valve of forty-five (45) feet; a developed length of pipe from the pressure-reducing valve to the most distant fixture of two hundred (200) feet; and fixtures to be installed with flush valves for water closets and stall urinals as follows: EXAMPLE: Fixture Units and Estimated Demands Branch to Building Supply hot-water system Kind of Fixtures Demand No. Demand No. (gallons of Fixture (gallons of Fixture per fix• units per Fixtures units minute) tures minute) Water Closets_.._ 130 1,300 Urinals .............. 30 150 Shower Heads.... 12 48 12 0 2x4)X 3/4 Lavatories /4130 260 130 (130x2)X 335 Service sinks .... 27 $1 = 195 27 (27x3)X 3Ya Total 7,839 310 292 1 661 Allowing for fifteen (15) psi. at the highest fixture under maximum demand of three hundred and ten 10) gallons per minute, the pressure available for friction loss is found by the following: 55-E5 + (45 X 0.43] = 20.65 psi The allowable friction loss per one hundred (100) feet of pipe is therefore 100 X 20.65 divided by 200= 10.32 psi If the pipe material and water supply are such that Chart A-5 applies, the required diameter of the building supply is three (3) inches, and the required diameter of the branch to the hot water heater is two (2) inches. The sixes of the various branches and risers may be determined in the same manner as the size of the building supply or the branch to the hot water system - by estimating the demand for the riser or branch from Charts A-2 or A-3, and applying the total demand estimate for the branch,riser or section thereof, to the appropriate flow chart.

(d) Rainwater piping commencing two (2) feet from ex- terior of a building may be of any approved material permitted in the Installation Requirements of this Code. D1.1 (a) Railwater piping shall not be used as soil, waste or vent pipes nor shall a soil, waste or vent line be used as a rainwater pipe. (b) Rainwater piping installed in locations where they may be subjected to damage shall be protected. (c) Roof drains, overflow drains, and rainwater piping when concealed within the construction of the building, shall be tested in conformity with the provisions of this code for testing drain, waste and vent systems. ta- 4 PART B ROOF DRAINS D2.0 MATERIALS: Roof drains shall be of cast iron, copper, lead or other corrosion resisting material. D2.1 STRAINERS; (a) Roof drains shall be equipped with strainers extending not less than four (4) inches above the surface of the roof immediately adjacent to the drain. Strainers shall have a minimum inlet area one and one-half (1 1/2) times the pipe to which it is connected. (b) Roof deck strainers for use on sun decks, parking decks and similar occupied areas may be of an approved flat surface type which is level with the deck. Such drains shall have an inlet area not less than two (2) times the area of the pipe to which the drain is connected. (c) Roof drains passing through the roof into the interior of a building shall be made water tight at the roof line by the use of a suitable flashing material. PART C SIZING OF RAINWATER PIPING D3.1 Vertical rainwater piping shall be sized in accordance with Table D-1. (Table D-1 is based upon maximum inches of rainfall per hour falling upon a given roof area in square feet. Consult local rainfall figures to determine maximum rainfall per hour.) D3.2 VERTICAL WALL AREAS: Where vertical walls project above a roof so as to permit storm water to drain to the roof area below the adjacent roof area may be computed from Table D-1 as follows: (a) For one (1) wall - add 50% of the wall area to the roof area figures. (b) For two (2) adjacent walls - add 35% of the total wall areas. (c) Two (2) walls opposite of the same height - add no addition area. (d) Two (2) walls opposite of differing heights - add 50% of wall area above top of lower wall. (e) Walls on three (3) sides - add 50% of area of the inner wall below the top of the lowest wall, plus allowance for area of walls above top of lowest wall per (b) and (d). (f) Walls on top (4) sides - no allowance for wall areas below top of lowest wall - add for areas above top of lowest wall per (a), (b), (d) and (e). D3.3 HORIZONTAL RAINWATER PIPING: The size of a building rainwater piping or any of its horizontal branches shall be sized in accordance with Table D-2 (Based upon maximum roof areas to be drained.)

This is written with the Code users in mind, and will detail only those measures used in everyday work and calculations. For the scientific units, we recommend the use of ANSI Z210.1 entitled "Metric Practice Guide." GENERAL COMMENTS Our present system of measuring involves the three dimen- sions of Force, Length and Time. The SI units involve Mass, Length and Time. The change of Force to Mass has meaning in scientific and engineering work, but for practical use, in ordinary construction, we will show kilogram to pounds conversion values although an exact conversion would be pounds force divided by the acceleration due to gravity to mass units. In the same manner, the SI units for temperature expressed in kelvins and based on absolute zero will be given as degrees celsius which is the more familiar and practical centigrade degrees. The SI system measures angles in radians where there are two pi radians in a circle, but using a 1.5708 bend to change from a vertical stack to a horizontal house drain is not as easy as calling out a 1/4 bend or an "el" for water piping. The foregoing notes are intended to show that in making conversions from one unit system to another, a little common sense must be used and the degree of accuracy needed to do the job, in hand, must be kept in mind. In any case, most conversions made by just substituting values fall within two percent of what we now use. I.e., a metre is pretty close to a yard and a liter is just about the same as a quart. The temperature conversions from school, when we had to divide by 5/9 and add 320 or was it multiply and subtract 3209 After all this, 5/9 is pretty close to 1/2 and water freezes at 320F and 00 celsius and the 1/2 factor will get in the ball park for everyday use. The following tables are set up using this approach and using the preferred SI units. As mentioned earlier, if you have to convert something in the nature of surveyor's chains to decame- ters,get a copy of ANSI Z210.1.

The final preferred units used will be those that apply to our industry and will of the magnitude to simplify and ease job calculcations and avoid confusion and ambiguity. The conversion looks complex and confusing, but when the metric system was proposed in France, an attempt was made to include a 10 hour day, a 10 day week and 10 months to the year, but cooler heads prevailed and our time still follows the sun and seasons. Likewise, assigning new units or numbers to the quantities we must work with cannot change the basic hydraulic principles that plumbers have worked with through- out history.

This model code is called the Uniform Plumbing Code and is published by the International Association of Plumbing and Mechanical Officials, of which the City of Fort Worth is a member. The Uniform Plumbing Code is also recommended by the North Central Texas Council of Governments for use by cities in the NCTCOG area. Many cities in this area, including cities such as Dallas, Arlington, Hurst and other mid-cities, use the Uniform Plumbing Code. The code is published by IAPMO every three years. Upon receipt of the publication, the Plumbing Appeals Board and staff review both changes and local amendments to determine where changes are needed. The pro- posed plumbing code, as amended: 1. Incorporates the changes to the Board of Appeals passed by the City Council on July 12, 1977 (Ordinance No. 7574 and M&C No. G-3497) . 2. Incorporates the State law on licensing of plumbing contractors and plumbing work permitted by licensed landscape irrigators. 3. Expands exemption from permit requirements to include such items as replacement of open traps, fixtures and appliances where no plumbing piping is changed (water heaters excluded), and the replacement of valves, It is felt that this change will benefit the home owner in making repairs. The previous provisions requiring permits were, for practical purposes, unenforceable. 4. Adds the following fees: $10.00 - Each sewer vent in a mobile home park. $15.00 - Inspection of manhole for checking of industrial wastes. These changes will affect only the commercial customer and not the home owner. 5. Includes the use of plastic piping for water service lines outside the building. This provision should cut down on corrosion by electrolysis. ' 6. Adopts many national standards that will enable the staff to approve materials and new type appliances. 7. Adopts requirements for sanitary facilities (water closets, urinals, lavatories, and drinking fountains) for schools, theaters and auditoriums, dormitories, offices or public buildings, industrial buildings and restaurants.
