with potable water.
One or more water pipes or hose connections
shall be available to the pool. There shall be no cross-connections
between the potable water system and the pool circulation system.
The water supply to the pool shall be protected against backflow or
back-siphonage of water by means of a fixed air gap of six inches
or more above the highest possible water level or by a properly installed
vacuum breaker. If a hose connection from a sill cock or other plumbing
fixture is to be used, an acceptable vacuum breaker shall be installed
on the hose thread of the sill cock or fixture. No over-the-rim fill
spout will be accepted unless located under a diving board or installed
in a manner as to prevent any hazard.
Facilities shall be provided for disposing of
all pool drainage and wastewater to the community sanitary sewer system
or in some other manner approved by the enforcing official. There
shall be a six-inch air gap between the pool discharge line and the

or to overflow onto adjoining property.
No surface or roof drainage shall be permitted
to enter the pool.
Pool floor and walls shall have a cleanable,
light-colored, and impermeable surface. The pool floor and the deck
shall be skid resistant. Where the water depth is less than five feet,
maximum cove radius shall be eight inches.
There shall be no hazardous projections or low
over-water construction in the pool or the pool enclosure which could
trap or injure bathers. The pool shall be shaped so that all parts
of the pool can be observed from a single vantage point on the pool
deck.
Every pool shall have at least one acceptable
ladder or set of steps.
Pool lights, if provided, shall be shielded
so as to direct the light away from adjacent premises.
Water treatment equipment shall be installed
above grade, except that it may be installed in a properly drained
residential basement, cellar, or other approved structure. Any accessory
building shall comply with applicable requirements of zoning and building
codes.
A walkway or deck of concrete or other approved
impervious material shall be constructed around the perimeter of the
pool and shall be at least three feet wide.
A. The minimum number of filtered water inlets shall
be determined as follows:
|
Number of Inlets
|
Pool Perimeter
(feet)
|
---|
|
1
|
0 to 60
|
|
2
|
61 to 120
|
|
3
|
121 to 180
|
|
4
|
181 to 240
|
B. Each of the minimum required water inlets shall be
at least 10 inches below the highest overflow line and at least 10
feet from any other inlet or from any skimmer, unless otherwise approved
by the enforcing official.
One or more outlets shall be placed at the deepest
point in every pool for circulating the pool water and for draining
the pool. The effective area of the drain grating shall be at least
four times the area of the outlet pipe.
Unless a continuous overflow weir and gutter
is installed around the pool, one or more surface skimmers shall be
provided. There shall be one skimmer for each 800 square feet or any
fraction thereof, which shall operate continuously while the pool
water is being circulated and which shall automatically adjust for
vertical variations in the water level of three inches or more. A
noncorrosive basket strainer accessible from the deck of the pool
shall be an integral part of the surface skimmer mechanism. All skimming
devices in a pool with a maximum depth exceeding five feet shall be
recessed or flush with the wall of the pool.
A flow-reducing valve shall be installed on
the discharge side of the pump. Valves shall be installed wherever
necessary for proper operation and maintenance of the circulation
system. Provisions shall be made for draining the filtration equipment.
The pump shall have sufficient capacity at maximum
anticipated hydraulic head to circulate the pool volume each 12 hours
and to supply the required backwash rate to any one filter. Unless
hydraulic analysis demonstrates otherwise, each pump shall supply
the required filtration rate at a total head of at least 50 feet for
any sand or anthracite filter system and 60 feet for a diatomite filter
system. The motor horsepower rating shall be determined for maximum
total head conditions at a twelve-hour pool volume turnover time.
A pump connecting to a pressure filter shall
be equipped on its inlet side with a noncorrosive hair and lint strainer.

its effectiveness.
D. The shell containing the filter media or elements
shall be constructed so as to provide satisfactory strength and freedom
from corrosion, and shall be installed in a manner to prevent settling
or upset.
A. Each pressure sand filter shall be provided with backwash
water at a minimum rate of 12 gallons per minute per square foot of
effective surface area.
B. Filter sand shall be uniformly graded silica material,
with effective particle diameters between 0.45 and 0.55 millimeters
and with uniformity coefficient less than 1.75. The sand shall be
free of clay, organic matter, and water-soluble material and no less
than 20 inches in depth, with a twelve-inch or greater freeboard.
C. Graded gravel or crushed anthracite shall be used
to support the filter media and shall be free of organic and water-soluble
material. It shall be graded by size and separately leveled in layers.
The total depth of the graded gravel shall not be less than 16 inches.
A. Each anthracite pressure filter shall be provided
with backwash water at a minimum rate of 12 gallons per minute per
square foot of effective surface area.
