If the power is out for an extended period (hours) and the utility estimate for restoration is long, the pH and ORP probes should be removed and placed into water to prevent damage due to drying out. | If the power is out for an extended period (hours) and the utility estimate for restoration is long, the pH and ORP probes should be removed and placed into water to prevent damage due to drying out. | ||

Observation has suggested that even a relatively brief outage (more than 30 minutes) may result in cloudy water being pumped to the pool upon startup. Therefore, it is recommended that a brief backwash is performed first after an outage above this threshold (until the outflow is clear). Otherwise, it may take several hours for the pool to clear. | Observation has suggested that even a relatively brief outage (more than 30 minutes) may result in cloudy water being pumped to the pool upon startup.
