Current through Bulletin 2024-18, September 15, 2024
(1) Valves.
(a) Valves shall be provided to allow
satisfactory operation and maintenance of a pump facility.
(b) Each pump shall have an isolation valve:
(i) on the intake side of the pump;
and
(ii) on the discharge side of
the pump.
(c) An air
release valve shall:
(i) be provided where
needed to allow the release of accumulated air in pump facility piping;
and
(ii) meet the requirements of
Subsection R309-550-6(6).
(d) If used, a foot valve shall be sized
according to the manufacturer's recommendation.
(2) Piping. Piping for a pump shall:
(a) have watertight joints; and
(b) be protected against surge or water
hammer
(3) Controls. Controls for a pump shall:
(a) be protected
from flooding;
(b) allow a pump
motor to operate at rated capacity without overloading;
(c) have proper overload protection for the
air temperature encountered;
(d)
provide for alternate operation of pumps where two or more pumps are
installed;
(e) prevent the pump
motor from starting during pump backspin;
(f) set start and cutoff pressures to prevent
continuous on-off cycling;
(g)
follow manufacturer's requirements for automatic cutoff pressure; and
(h) prevent surge pressures from activating
controls that turn on pumps or other equipment outside the normal design cycle
of operation.
(4) Water Pre-Lubrication of Pump Bearings. If water is used for automatic pre-lubrication of pump bearings, and an auxiliary direct-drive power supply is provided:
(a) the pre-lubrication line shall
have a valved bypass around the automatic control so that the bearings can be
lubricated manually before the pump is started; or
(b) the pre-lubrication controls shall be
wired to the auxiliary power supply.
(5) Pressure Measurement. A pump or group of pumps operating together shall have a means of measuring pressure:
(a) on the discharge line; and
(b) on the intake line capable of indicating
positive and negative pressure.
(6) Standby Power Supply.
(a) A community water system that relies
solely on a pump facility to supply water to a service area shall be provided
with standby power, power using a permanent or portable generator or electrical
service from two independent substations.
(b) If a fuel-operated generator provides
standby power:
(i) the water supply shall be
protected from contamination from the fuel supply and fuel line; and
(ii) a carbon monoxide detector shall be
installed if the generator is located indoors.
