Section 4-9 - Pool Pumps, Requirements; Uses

(a) A pump and motor shall re-circulate the pool water.

  • (i) A hair and lint strainer shall be located on the suction side of the pump;
  • (ii) The strainer shall be at least equal in size to the pump suction line; and
  • (iii) Strainers installed below water level shall have a valve on each side to facilitate cleaning.

(b) The performance of pumps shall meet the conditions of flow required for filtering and backwashing the filters against the total dynamic head developed by the complete system.

  • (i) The pumps shall be capable of providing design flow rates at no less than sixty (60) feet (1.83kg/cm²) of total dynamic head.

(c) Pumps shall be capable of pumping at a rate sufficient to turn over the total pool volume within the periods of time specified in section 13(b) of this chapter.

(d) Pumps on public swimming pools shall comply with the NSFS-50, Circulation System Components and Related Materials for Swimming Pools, Spas/Hot Tubs.

(e) Pumps shall be sized so as to pump the flow required in subsection (c) of this section under the filter soil conditions described in the following chart:

High rate sand filters

Filter soil conditions such as to create a fifteen (15) psi (1.06kg/cm²) increase above that created using clean filter media.

Rapid sand filters

Filter soil conditions such as to create an eight (8) psi (.56kg/cm²) difference between influent and effluent pressures.

Diatomaceous earth filters

Filter soil conditions such as to create pressures or vacuums at which manufacturer's recommend filter cleaning.

Cartridge Filters

Filter soil conditions such as to create a ten (10) psi (.70kg/cm²) difference between influent and effluent pressures.

(f) A spa pool shall have a two (2) pump recirculation system.

  • (i) One pump will provide the required turnover rate, filtration and disinfection for the spa water; and
  • (ii) The second pump shall provide the water for the hydrotherapy turbulence of the water.
