Re: What does the “whirlpool” setting do? The whirlpool feature bypasses the filter. The reason for this is that the filter will decrease the water flow and pressure, so bypassing it will create greater flow from the return line.Click to see full answer. In this manner, what does the winterize setting on my pool pump do?After a backwash and rinse, place the valve to the “winterize” setting on the top mount valve. This will allow water to drain from the valve. Place the sand filter, pump, hoses, and the drain cap in a dry, safe place until the pool is ready to be used again.Additionally, when would you use recirculate on pool filter? RECIRCULATE. This setting is used to bypass the filter during certain pool cleanups and chemical treatments when you don’t want the water contaminating the sand. Water enters the valve through the “PUMP” port and exits back to the pool through the “RETURN” port. Correspondingly, is recirculate the same as whirlpool? Whirlpool is the same as recirculate.What does Rinse do in pool filter?In a sand filter, the rinse cycle allows water to flow back down through the sand to flush out any remaining dirt and debris from the filter and piping. The rinse cycle also restratifies (deposits in layers) the sand, letting it resettle in the filter tank.
