18-29-1204.14.4  Backwash filter rate.
   The pump used for backwashing filters shall have sufficient capacity to provide a backwash filter rate of at least 15 gpm per square foot (56.8 lpm/0.09 m 2 ) of filter area.
18-29-1204.14.5  Hair and lint strainer.
   A hair and lint catcher or strainer shall be installed on the suction side of the circulation pump to prevent hair, lint and other extraneous material from reaching the pump filters. Hair and lint catchers shall be so designed that they can be easily dismantled for cleaning and inspection and shall be so located as to be easily accessible for cleaning. The design features shall be as follows: Water passes through the strainer from the outside; the strainer is made of non-corrosive material; the width or diameter of the miner openings is not more than 1/8 inch (3 mm); the area of the strainer openings shall be at least five times the cross sectional area of the inlet pipe to the strainer.
18-29-1204.14.6  Pressure filters.
   Recirculating systems shall contain rapid pressure filters. Sufficient filter area shall be provided to filter the entire contents of the pool in six hours at the rate of not more than 3 gallons per square foot (11.4 L/.09 m 2 ) filter area per minute. The filter backwashing facilities shall be sufficient to backwash at the rate of 15 gallons per minute (12.5 L/0.09 m 2 ) filter area. All backwash water and effluents shall be discharged to the sewer through an indirect connection. Pressure filters shall be equipped with readily accessible air relief valves, loss of head or pressure gauges on the inlet and outlet pipes, and an access head or hole large enough to permit inspection, maintenance and repair work. Sight glasses that can be easily removed for cleaning shall be provided in the effluent line from the filter units.
18-29-1204.14.7  Disinfection equipment.
   Equipment shall be provided for the disinfection of all pool water. Any disinfection method using materials other than chlorine compounds shall be subject to the approval of the board of health. Disinfection equipment installed for the use of chlorine compounds shall have sufficient capacity to maintain a minimum free chlorine residual of 0.5 parts per million. The disinfectant shall be introduced into the recirculation system ahead of the filters.
18-29-1204.14.8  Gaseous chlorination systems.
   Gaseous chlorination systems shall not be made use of as a disinfection method for pool water.
18-29-1204.15  Electrical installations.
   All electrical installations provided for, installed and used in conjunction with private residential swimming pools shall be in conformance with Title 14E.
(Amend Coun. J. 9-6-17, p. 55278, Art. II, § 65)
18-29-1204.16  Maintenance.
   All private residential swimming pools shall be maintained in a satisfactory operating condition during the periods the pool is in use.
18-29-1204.17  Inspection.
   The board of health periodically shall inspect all private residential swimming pools to determine whether or not the provisions of this code regarding health, sanitation and safety applicable thereto are being complied with.

Appendix A
Procedures for Calculating the Minimum Sizing of the Water Supply System
For a printer-friendly PDF version of Appendix A, please click here.
   The following is a procedure that shall be used in calculating the minimum sizing of the water supply system:
Step 1.   Compute the total number of fixture units from Table 18-29-604.10.1, Demand Weight of Fixtures in Fixture Units.
   1.   For supply outlets likely to impose continuous demands, estimate continuous supply separately and add to total demand for fixtures.
   2.   For fixtures not listed, weights may be assumed by comparing the fixture to a listed one using water in similar quantities and at similar rates.
   3.   The given weights are for total demand. For fixtures with both hot and cold water supplies, the weights for maximum separate demand may be taken as three-fourths the listed demand for supply.

Step 2.   Using Table 18-29-604.10.2, convert the total water demand from fixture units to gallons per minutes (gpm). Add any continuous supply demand in gpm such as lawn sprinklers, air conditioning, industrial uses, etc., to the sum of the total demand for fixtures. The result is the total required gpm demand. All distributing pipes, riser pipes and branch distributing pipes shall be sized in accordance with the demand indicated in Table 18-29-604.10.2 of this chapter.
Beyond the capacity listed in Table 18-29-604.10.2, the service pipe, main supply pipe, principal supply pipe and the branch supply pipe shall be sized to meet the velocity of water flow provisions of this chapter. Data shall be provided by the designer to substantiate this.

Step 3.   Determine the elevation of the highest fixture or group of fixtures or water opening above the city water main or other source of pressure supply. Multiply this elevation in feet by 0.434. The result is the loss in static pressure in pounds per square inch (psi).
Step 4.   Compute the size of meter necessary for a total water demand.
Step 5.   Compute the pressure loss through the meter. For pressure losses, consult manufacturer's data.
Step 6.   Compute the available pressure to overcome friction in the piping system. First compute all losses (see below):
1)   Subtract the above losses from the minimum service pressure in the water main or other source of supply. The remaining is the available pressure to overcome friction within an upfeed piping system.
2)   For gravity water tanks, determine the vertical distance between the incoming water service, the minimum tank water line, and the highest fixture or group of fixtures or water opening. To find the available pressure to overcome friction in the downfeed piping system, multiply the distance defined above by 0.434, then subtract the above losses from this pressure. The remaining is the available pressure to overcome friction within the downfeed piping system.
Step 7.   Compute the developed length of the basic circuit of piping from the main in the street, the house pump, the outlet side of the pressure-reducing valve or other source of supply pressure to the highest and farthest outlet.
For a gravity water tank, compute the developed length of the basic circuit of the piping from the tank connection to the highest and most remote outlet. Developed length plus 50 percent will approximate the equivalent length run (ELR).
Step 8.   Compute the pressure factor per 100 feet of developed length. From the above calculations, take the pressure available for friction loss in psi, (Step 6) divide by the equivalent length run (ELR) (Step 7) and multiply by 100 to ascertain the maximum uniform pressure loss for friction in the piping of the basic circuit. (See Table 18-29-604.10.3)
Step 9.   Knowing the permissible uniform friction loss per 100 feet of pipe and the fixture gpm and all continuous demands in gpm, the diameter of the building service and main supply pipe to the cold and hot water branch or the first branch may be obtained from Table 18-29-604.10.2.
The diameter of pipe on the coordinate point corresponding to the estimated demand and the permissible uniform friction loss shall be the size of the service and main supply pipe to cold and hot water branch or the first branch.
All other piping in the water supply system shall be sized according to the full-listed demand weight, with the exception of piping that supplies fixtures with both cold and hot water, which may be sized at three-fourths of the listed demand weight for cold or hot water piping. All continuous demands on the piping system shall be included in the fixture gpm demand.
For fixtures not listed, demand weights may be assumed by comparing the fixture to a listed one using water in similar quantities and at similar rates.
      The cold and hot water principal supply pipe, branches and risers may be obtained from either Table 18-29-604.10.3 or 18-29-604.10.4, whichever is applicable. The diameter of pipe on or directly above the coordinate point corresponding to the estimated demand and the permissible uniform friction loss shall be the size of the pipe.
No service shall be less than 1 inch nominal pipe size. Where 1 inch flushometer valves are used, the minimum size of water service shall be a 1 1/2 inch nominal pipe size and the minimum size of the riser shall be a 1 1/4 inch nominal pipe size. No riser shall be less than 3/4 inch nominal pipe size.
