Once a day, a technician should take the reading on the backwash counter and filter inlet/outlet pressure, and enter the information into a logbook. We have included a suggested log sheet at the end of this section.
Once a week, a manual backwash should be initiated. During the backwash cycle, the opening and closing of the valves should be verified.
In the Spring and in the Fall seasons, verify the media level by opening the Victaulic coupling at the back of the filter. Please refer to your Operation and Maintenance manual for complete procedure.
