If the filter pressure continues to run high with reduced water flow to the pool, the pump may be moving more water than the filter is designed to handle. Check the flow ratings of both the pump and filter to ensure they are sized correctly. You may have a blocked or plugged return line.
The main reason for running the pool pump during the daylight hours is to ensure proper sanitation. Chlorine is degraded by sunlight, so there is a larger demand on the chlorine residual during the day. When the pool pump is operating, the circulation in the pool disperses the chlorine throughout the pool. Also, most pools use some type of chlorinator that adds chlorine only when the pump is running. By running the pump during the day, it helps keep the chlorine at a constant level. Use of the pool also consumes the chlorine, and most swim during the day. Having the proper levels of chlorine helps kill algae spores, germs, bacteria and other contaminants as soon as they enter the pool.
