tive supported septum surface. In the case of fabric septums, the area compu-
tation will be made on the basis of measurements of the septum support in a
reasonable constant plane. Area allowance shall not be granted for folds in
the septum fabric or deviations in the septum surface which would easily
bridge.
Ic)
The tank containing the filter elements shall be constructed of steel, plastic
or other suitable material which will satisfactorily provide resistance to cor-
rosion, with or without coating. Pressure filters shall be designed for a work-

ded by water, then a suitable corrosion resistant coating shall be applied to
retard such attack.
(d)
The filter elements shall be fabricated of corrosion resistant materials through-
out. They shall be designed to be adequately resistant to a differential pres-
sure between influent and effluent of not less than the maximum pressure,

effluent from the filter shall be recireulated or run ~o waste and shall not be
fed into the pool until free of filter aid. An exception to this requirement may
ce made if ,he filter septum ~-s of such construction that no perceptible quantity
of filter aid is introduced into the pool when the effluent discharges therein.
(g)
Where dissimilar metals are used in the construction of the filter, whichmay
set up galvanic currents, then suitable provisions shail be made to resist elec-
trolytic corrosion.
(h)
Filters shall be so designed and installed that they can be readily disassemble
and the filter elements removed.

Cartridge type filters are those where the cartridge itself is the filter aid.
~ridge filters can be either pressure or vacuum type and are subject to the same
-~al piping and tank specifications as diatomite-type filters. Replacement cartridges
are divided into two types: depth and area. General specifications, however, are
the same for both. Cartridge filters shall not require the addition of any flocculating
agents, such as ammonium alum, aluminum sulfate or potassium alum. They shall be
subject to the sa-me mechanical requirements for alt types of filters. All types of car-
tridges shall have sufficient structural strength to resist rupturing, channeling,
collapsing or bursting at a maximum pressure differential of fifty pounds per square
inch. Cartridge seals shall be so designed as to prevent any by-passing
water. If provision is made for backwashing, it shall be so arranged as to not
any backwash water to enter the recircutating system. No residue shall be permitted
to remain in the filter housing that could be picked up in the next filtering cycle.
(a)
Depth type cartridges are elements where the porosity varies from the inlet of
the discharge surface. They shall have sufficient depth to provide adequate
dirt-holding capacity and be designed for a flow of no more than one gallon
per minute per five cubic inches of volume with a pressure drop not to exceed
two pounds per square inch across clean cartridges and not to pass any parti-
cular matter larger than twenty-five microns.
(b)
Area or surface zype cartridges are those which rely on the surface area for
their dirt-holding capacity, and they should follow the same flow per square
foot of area as diatomite filters, namely, three gallons per minute per square
foot of area for pressure filters and two and one-fourth gallons per minute per
square foot of filter area for vacuum filters.
Each filter shall be capable of filtering the entire contents of the swimming poo~
n eighteen hours or less. Filter capacity shall be such that it meed not be cleaned
more frequently than once every four days under proper conditions of water and
operation. All filters shall be designed so as to permit easy removal of the cartridge~
10
Eec. 25B-29. Recirculating pumps
The recircuiating pump of a swimming pool shall have sufficient capacity to
provide the rated flows of the filter system, without exceeding the head loss at which
the pump will deliver such flows, The pump motor shall not be operated at an over-
load which exceeds the service factor.
Sec, 2§B-30. Hair and lint strainers
Each swimming pool pump shall be equipped on the inlet side with an approved[
type hair and lint strainer ~ except for vacuum type fillers where water passes +Jlroug~
he filter before reaching the pump. The basket of the strainer shall be
and have an open screen surface of at least four times the cross sectional area of the
[filet pipe.
Sec. 25B=31. Tests and inspections
AH swimming pool piping and the installation and construction of the pool pip-
ing system shall be in accordance with approved plans. The entire pool piping sys-
tem shall be tested with a water test of fifty pounds per square inch and proved tight
before covering or concealing. AH piping shall be hung to the patio wire mesh or
pool steel in such a manner as to prevent strain. Hangers shall be 1/4" steel rod.
In corrosive soil, hangers shall be tar coated. No pipe work on a ~ool or part there-
of shall be covered until it has been inspected, tested and approv~-d by the plumbing
inspector. If any of this pipe work or part thereof is covered before being regularly
inspected, tested and approved, it shall be uncovered upon the order of the plumb-
ing inspector.
Sec. 25B-32. Piping: size; velocity of water
~ . Swimming pool pipzng shall be sized to permit the rated flows for filtering and
I~le=n~ng without exceeding the maximum head at which the pump will provide such
i~aows. In general, the water velocity in the pool piping should not exceed ten feet
~Der second. Where velocity exceeds ten feet per second, summary calculations ~
provided to show thai rated flows are possible with the pump and piping provided

Pool rec~rcuiating piping, passing through the pool structure, shall be copper
tubing with a minimum wall thickness of type "L", schedule eighty (80) PVC ~
brass or an approved equal. Metal pipe shall be bituminously coated.
(d)
Where pool heaters are installed, recirculating piping within four feet of the
heater must be either copper type "L", schedule eighty (80) PVC, or brass
pipe.
(e)
Filtered water inlets shall be provided in sufficient quantity; a mmimum of

Sec. 25B-34. Surface skimmers permii!.ed in lieu of overflow gutters
Surface skimmers of approved type may be permitted in
in swimraing pools, and the dramage of all decks and paved concrete areas ad3acent
to the pool shall be away from the pool. One skimming device shall be provided for
sach six hundred square feet or fraction thereof of the pool area.
Sec. 25B-35_ Requirements as to surface skimmers; generally
~ Surface skimming devices for swimming pools shall be built into the pool v~alts
~hall remove floating ~ils and other floating wast~ material and Shall meet t~e follow-
ing general specifications:
(a)
(b)
(c)
(d)
(e)
(f)
g)
(h)
Each skimmer shall be designed for a i/ow-through rate of at least twenty gal-
lons per minute and the total~ capacity of all skimmers in any pool shall be
approximately eighty percent of the required filter flow of the recirculating
system.
A floating weir shall be provided as a part of the skimming device, which Shall
establish the water level at which it overflows into ~he skimmer and this weir
s~hall have a free self-adjusting range in elevation of not less than four inches,
during which range it will be fully effective.
An easily removable and cleanable basket or screen through which all over-
flow water must pass shall be provided to trap large solids.
The skimmer shall be provided with a device to prevent alrlock in the suction
line. If an equalizer pipe is used, it shall ~
up water for pump suction, should the water of the pool drop below weir level
This pipe shall be at least one and one-half inch in diameter and shall be loca-
ted at least one foot below the lowest overt/ow level of the skimmer weir.
This equalizer line shall be provided with a valve that will remain tightly
closed under normal opera~on conditions but will automatically open at a
differential of not more than four inches between the pool level and the level
of the overflow tank.
Where multiple skimmers are used in a swimming pool, they shall be provided
with means of adjustments and reg~alations which will approximate uniform
through all of the skimmers which are provided and installed and piped toge-
ther direc~y to the pump suction for rec~rculation.
Skimmers shah be of substantial, enduring and reasonably
material.
Inlets for returning the filtered water to the swimming pool shall be ar-~anged,
with the total number as covered in this chapter, but spaced between the skim-
mag devices so that no inlet is directly in line with a skimmer, and all inlets
should be spaced at least five feet away from any skimmer. Total operating
head of the recirculation system and the sizing of pipe must be such that the
residual pressure at the wall fitting of all inlets shall be not less than that
which will provide a velocity of ten feet per second at the point where the in-
let discharges into the pool body.
One skimmer sha~l oe placed at a point in the pool opposite the direction of
preva~!ing summer winds.
If a surface skimmer is used in lieu of a scum gutter, an overflow opening
shall be provided. It ma be "
, y a connection ou~ o~ the surface skimmer or an
opening through the pool wall placed two inches above the high water level of
12
the pool. This overflow shall be run directly to a drain field or to a storm
drain.
Eec. 25B-38. Overflow gutters
If an over,ow gutter (scum gutter) is used in swimming pool, it shall have a
minimum len~h of ten feet or shall be across one entire side Or end. It shall be a
minimum of three inches deep, slope one-fourth inch to a foot, and have a two-inch
drain at least every ele~en feet. The gutter edge shall be true to line and the lip
shall be 2urved ~o be used for a hand bold.
If pools where sUrface skimmers are not employed, continuous overfiow
shall operate in a manner so that the overflow ~from the gutter shall overflow freely
and continuously to waste or a recirculating pump.
Eec. 25B-37, Valve materials
Swimming pool valves up to and including two inches in size shall be brass,
Sizes over two inches m ' ·
ay nave cast-Iron or brass bodies. All working parts of
· alves shall be non-corrosive material.
ec. 25B-$$~ Futlway valves re~
Fullway valves shall be installed throughout the swimming pool filtration and
p~ping system to insure proper functioning of the filtration and piping system.
_~ec, 25B-39_~ Valves on suction line
valve shall be installed on the main suction line of the swimming pool, loca-
ted'in an accessible place outside the walls of the pool when the pump is below the
overflow rim of the pool.
Sec. 2§B-~0. Combination valves
Combina~on valves may be installed in swimming pools if the materials and
design comply with the intent of the standards set out in this chapter.
