Section 675IAC14-4.3-286. Circulation system

   Section S4217 Circulation system is added as follows:

(1) S4217.1 A circulation system consisting of pumps, piping, return inlets and suction outlets, filters, and other necessary equipment shall be provided for complete circulation of water through all parts of the pool. This circulation system shall be capable of maintaining water clarity and chemistry requirements.

(2) S4217.2 The equipment shall be of adequate size to turn over the entire pool water capacity at least once every twelve (12) hours. Water clarity shall be maintained. When standing at the pool's edge at the deep end, the deepest portion of the pool floor shall be visible.

(3) S4217.3 Circulation system components that require replacement or servicing shall be:

(A) accessible for inspection, repair, or replacement; and

(B) installed according to the manufacturer's instructions.

(4) S4217.4 Pool equipment shall be:

(A) properly supported to prevent damage from misalignment, settlement, etc.; and

(B) mounted so as to minimize the potential for the accumulation of debris and moisture following manufacturer's instructions.

(5) S4217.5 The water velocity in the pool piping shall not exceed ten (10) feet per second for discharge piping and eight (8) feet per second for suction piping, unless summary calculations are provided to show that the greater flow is possible with the pump and piping provided. In copper pipes, the velocity shall not exceed eight (8) feet per second for suction and discharge piping. Pool piping shall be sized to permit the rated flows for filtering.

(6) S4217.6 The circulation system piping and fittings shall be:

(A) nontoxic;

(B) considered to be process piping; and

(C) of material able to withstand operating pressures and operating conditions.

(7) S4217.7 Equipment shall be designed and fabricated to drain the pool water from the equipment, together with exposed face piping, by removal of drain plugs and manipulating valves, or by other methods. Refer to manufacturer's recommendations for specific information on draining the system.

(8) S4217.8 A pressure or vacuum gauge or other means of indicating system condition shall be provided in the circulation system in an easily readable location.

(9) S4217.9 Time clocks may be used to set the operating period of the circulation system. When time clocks are used, they shall also govern the operating time of appurtenant devices such as chemical/disinfectant feeders, slurry feeders, heaters, etc., that are dependent upon circulation pump flow.

(10) S4217.10 Written operation and maintenance instructions shall be provided for the circulation system.
