(3)The pool water must be maintained at a pH of no less than 7.2 and not greater than 9.4.
(4)The pool must provide sufficient water volume exchange to produce an 8-hour turnover of the entire volume of pool water to waste. In addition:
(a)the pool, and all surfaces that flow into the pool, must be drained, cleaned, and sanitized every 72 hours; or
