12VAC5-481-2890. Pool water purity.
A. Pool water purification system shall be run sufficiently to maintain the conductivity of the pool water below 20 microsiemens per centimeter under normal circumstances. If pool water conductivity rises above 20 microsiemens per centimeter, licensees shall take prompt actions to lower pool water conductivity and shall take corrective actions to prevent future recurrences.
B. Licensees shall measure the pool water conductivity frequently enough, but no less than weekly, to assure that the conductivity remains below 20 microsiemens per centimeter. Conductivity meters shall be calibrated at least annually.
