Corrective Actions: Install and maintain a flow meter in the recirculation piping, measuring flow in gallons per minute. Mount the flow meter per manufacturer's recommendation in a location where it can be easily read, and on a length of straight pipe.ADD FLOW METER

333-062-0165(1.3) VIOLATION OF OAR 333-062-0165 (1) The combined chlorine (chloramine) is greater than 0.5 ppm (0.5 mg / kg). Specifically:1.4 PPM
Corrective Actions: Maintain the combined chlorine (chloramine) residual within the range set out in spa Water Quality Parameters, OAR 333-062-0165, and Table 1, the ideal being 0.0 ppm, measured combined chlorine. Combined chlorine (chloramines) is irritating to swimmers and an air quality and health concern at indoor pools.
