How do you use the waste setting on pool pump?

The waste setting on a pool pump is used to remove water and debris directly from the pool, bypassing the filtration system. To use it, first, ensure the pump is turned off, then adjust the multiport valve to the waste position. Start the pump, and it will drain water out through the waste line, which is useful for lowering the water level or during backwashing. Monitor the water level closely to avoid draining too much water from the pool.
