(5) Circulation system piping, other than that integrally
included in the manufacture of the pool or spa, shall be subject to an
induced static hydraulic pressure test for six hours at a pressure 50%
greater than the maximum design operating pressure of the system
or 25 pounds per square inch whichever is greater. This test shall
be performed before the deck is poured, and the pressure shall be
maintained throughout the deck pour.
(6) The circulation system piping and fittings shall be
nontoxic, and shall be of material(s) able to withstand operating
pressures and operating conditions. Polyvinyl chloride pipe shall
bear the NSFI seal for potable water and be schedule 40 or stronger.
(7Q Pool or spa piping subject to damage by freezing shall
have a uniform slope in one direction and equipped with valves for
adequate drainage or shall be capable of evacuating water to prevent
freezing and possible damage. Pool or spa piping shall be adequately
supported and designed to prevent entrapment of air, water or dirt.
Provision shall be made for expansion or contraction of pipes.
( Equipment shall be designed and fabricated to drain
the pool or spa water from the equipment, by removal of drain plugs
and manipulating valves, or by other methods.ing:
(9 All pools and spas shall be equipped with the follow-
(A) a pump suction (vacuum) gauge installed as close
to the suction side of the pump as possible without sacrificing
accuracy;
(B) a filter inlet pressure gauge installed on the piping
ahead of the filter in the area of greatest pressure;
(C a filter outlet gauge; and
(D) a rate of flow meter located to accurately (plus or
minus 10%) indicate the rate of flow through the filter (during filtering
as well as backwashing) in gallons per minute.
(c) Exposed piping color-coding for new and existing pools
and spas. Exposed piping in new pools and spas shall be color-coded
according to the following color scheme. It is recommended that
piping on existing pools and spas also be color-coded. If any two
colors do not have sufficient contrast to easily distinguish between
them, a six-inch band of contrasting color shall be painted on one or
more of the pipes at approximately 30-inch intervals. The name of
the liquid or gas and arrows indicating direction of flow, should be
painted or otherwise permanently indicated on the pipe.
Figure: 25 TAC, 265.187(c).
265.188. Filters.
(a) Filters for new pools and spas. Filters for new pools and
spas shall meet ANSI/NSFI Standard-50-1996.
(b) Replaced filters for existing pools and spas. When
equipment is replaced on existing pools and spas, that equipment
falling within the scope of ANSI/NSFI Standard-50-1996 shall meet
this standard.
(c) Filter design and operation for new pools and spas. Filters
for new pools and spas shall be designed so that after cleaning
according to the manufacturer's instructions the system provides the
water clarity noted in 265.203(c) of this title (relating to Operation
and Management) (Water clarity standards for new and existing pools
and spas).
(d) Filter accessibility for new pools and spas. Filters for
new pools and spas shall be installed so that filtration surfacesare accessible for inspection and service as per manufacturer'sji
specifications.
(c) Filter and separation tank pressure release for new pools
and spas. Any filter or separation tank for a new pool or spa shall
have both manual and automatic means of air release which provide
a slow and safe release of pressure as a part of its design.
(f) Filter and separation tank instructions for new pools and
spas. Pressure filters and any separation tank for new pools and
spas shall have operation and maintenance instructions permanently
installed on the filter or separation tank and shall include a precaution-
ary statement warning not to start up the system after maintenance
without first opening the air release and properly reassembling the
filter and separation tank. The statement shall be readily visible from
the area of the air release and the start-up controls.
(g) Observable waste discharge for new pools and spas.
Pressure filters for new pools and spas shall be provided with a readily
observable free fall or sight glass installed on the waste discharge line
in order that the filter washing progress may be observed. Where sight
glasses are used, they shall be readily removable for cleaning.
(h) Backwashing for new pools and spas. Filters for new
pools and spas shall be backwashed and maintained according to
manufacturer's instructions.
265.189. Pumps and Motors.
(a) Safe pump operation for new and existing pools and spas.
A pump for a new or existing pool or spa shall not be operated if
the main drain grate, anti-vortex suction outlet, or any suction outlet
cover is missing, broken or loose. The pool or spa shall be closed
immediately and remain closed until a proper repair or replacement
has been accomplished.
(b) Safe pump design and operation for new pools and
spas. The design, construction and installation of the pump(s) and
component parts for new pools and spas shall provide safe operation
as per manufacturer's specifications. Pumps for new pools and spas
shall comply with UL and/or NEMA requirements.
(c) Priming device cross-connection control for new and
existing pools and spas. Any priming device for a new or existing
pool or spa pump receiving piped water from a potable water
supply shall be isolated from the potable supply by means of a
cross-connection control device as approved by the TNRCC or the
department or state or local regulatory authority.
(d) Pump and motor provided for circulation for new and
existing pools and spas. A pump and motor shall be provided for
circulation of new and existing pool and spa water. Performance
of all pumps for new pools and spas shall meet the filter design
range of flow required for filtering as stated in 265.187(b)(1) of
this title (relating to Circulation Systems) and cleaning the filters (if
applicable) against the total dynamic head developed by the complete
system and to meet the clarity noted in 265.203(c) of this title
(relating to Operation and Management (Water clarity for new and
existing pools and spas)).
(e} Cleanable strainer for new pools and spas. With all
pressure filter systems for new pools and spas, a cleanable strainer
or screen shall be provided upstream of the circulation pump(s) to
remove solids, such as debris, hair, and lint, and shall be readily
accessible and cleaned routinely.
(f Pumps and motors accessible for new pools and spas.
Pump(s) and motor(s) for new pools and spas shall be accessible for
inspection and service as per manufacturer's specifications.23 TexReg 12102 December 4, 1998
