the suction line. If an equalizer pipe is used, it shall provide an
adequate amount of make-up water for pump suction should the water
of the pool drop below the weir level. This pipe shall be at least
two inches in diameter and shall be located at least one foot below
the lowest overflow level of the skimmer.
5.Â
An equalizer line shall be provided with a valve that will remain
tightly closed under normal operating conditions, but will automatically

of flow of at least 20 gallons per minute per linear foot of weir
lip.
No source of water other than that secured from the City waterworks
distribution system shall be used in swimming pools.
A.Â
Swimming pool water recirculation system inlet shall be located so
as to produce so far as possible uniform circulation of water throughout
the pool without the existence of dead spots and to carry pool bottom
deposits to the outlets, and shall discharge at a minimum depth of
10 inches below the pool over flow level. A minimum of one recirculation
system inlet shall be provided for every 615 feet square feet of surface
area of the pool.
B.Â
Pools shall be equipped with suitable facilities for adding make-up
water as needed. There shall be no physical connection between the
water supply line and the pool system. If the make-up water supply
line discharges to a surge or balancing tank, the point of discharge
