The Hayward 1.5 Inch SP0710X62 6 position replacement Side Mount Multiport Valve is made for Hayward Pro Series Sand Filters. This Vari-Flo multiport control valve is engineered for maximum flow at lower pressure drops. Hayward valves feature an easy-to-use lever action handle that lets you dial up to six valve/filter functions: filter, backwash, waste, rinse, closed or recirculate. This valve comes complete with an integral sight glass allowing you to see when the backwashing cycle is completed. The Vari-Flo Control Valve's functions include: 

FILTER - For normal filtering and regular vacuuming

BACKWASH - For cleaning filter sand bed of accumulated debris 

RINSE - For use after completing backwash cycle to ensure all dirty water is rinsed out of the filter to waste

WASTE - By-passes the filter for draining or lowering pool water level and for vacuuming heavy debris directly to waste line

RECIRCULATE - Water is recirculated through the valve, by-passing the filter

CLOSED - Shuts off the flow from the pump to the filter. 

The SP0715X62 six-position valve has an easy-to-use handle, heavy duty stainless steel spring, ABS body and cover, neoprene valve seat and a built-in sight glass. Automatic self-cleaning design prevents clogging or sticking.
