Section XXIV-901 - Disinfectant Equipment and Chemical Feeders [formerly paragraph 24:017]

A. Disinfectant equipment and chemical feeders, hereinafter referred to jointly as "equipment," shall comply with the requirements of NSF Standard 50. The disinfection equipment shall be capable of precisely introducing a sufficient quantity of an approved disinfecting agent to maintain the appropriate recommended guidelines required concentrations as per §903

1. Every pool shall be required to have at least one unit of disinfectant agent equipment in compliance with §901. A.2 Additional units may be required to maintain chemical and physical parameters of the pool water.

2. The pool water shall be continuously disinfected by a disinfecting agent that imparts an easily measured residual. The disinfecting agent used shall be subject to field testing procedures that are simple and accurate.

B. Chemical Feeders. The installation and use of chemical feeders shall conform to the following.

1. When using chemical feeders, it is extremely important that they be installed downstream from the filter and heater. Erosion-type feeders shall be allowed to feed their solution to the suction side of the pump.

2. If the chemical feeder is equipped with its own pump, it shall be installed so it introduces the gas or solution downstream from the heater and, if possible, at a position lower than the heater outlet fitting.

3. Swimming pools and wading pools which are equipped with gaseous or liquid chlorination feeders must be equipped with a mechanical chemical feeder to continuously control pH. Hand batch feeding of any pH chemical into the pool is expressly prohibited.

C. Test Kit. All pools shall be supplied with chemical test kits for the determination of pH, chlorine or bromide residuals, cyanuric acid (if used), total alkalinity, and calcium hardness. The test kit shall be capable of at least measuring pH and disinfectant residual ranges, as required. The method used in determining the free available chlorine residual shall be such that chloramines or other chlorine compounds that may be present in the pool do not affect the determination.
