Section R309-540-7 - Pump Appurtenances(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.Utah Admin.
