1. A. The water velocity in the pool piping shall not exceed 10 feet per second for discharge piping, (except for copper pipe where the velocity should not exceed 8 feet per second), and 6 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. Pool piping shall be sized to permit the rated flows for filtering and cleaning without exceeding the maximum head of the pump.

   1. 1. A wading pool shall have a separate circulation system of adequate size to turn over the entire pool water capacity at least once every two hours.

2. B. Piping and Fittings. The circulation system piping and fittings shall be non-toxic, shall be considered to be process piping, and shall be of material able to withstand operating pressures and operating conditions.

   1. 1. Pool piping subject to damage by freezing shall have a uniform slope in one direction equipped with valves for adequate drainage. Pool piping shall be supported at sufficient intervals to prevent entrapment of air, water or dirt. Provisions shall be made for expansion or contraction of pipes.

3. C. System Condition. A pressure or vacuum gauge or other means of indicating system condition shall be provided in the circulation system in an easily readable location.

   1. 1. Class A, Class B, and Class C public pools shall be provided with an indicator measuring the rate of flow through the filter system with an appropriate range readable in gallons per minute and accurate within 10 percent actual flow.
