Your pool filter can do so much more than just clean the pool water. Located on the top or side of the filter, the multiport valve’s numerous settings direct the pool water where you need it to go, allowing you to use the filter for multiple purposes.
In swimming pool terminology, a multiport valve is a valve used to backwash a sand or DE pool filter. A multi-port valve has many internal ports (hence the name), and enables the pool owner to Backwash the filter with the turn of a single valve handle, instead of several. Other commonly used functions include Rinse to flush out any residual dirt after backwashing, and Drain to Waste, for vacuuming to waste or lowering the water level without backwashing. Recirculate is used when the filter is in need of repair - if you can't filter the water, at least you can circulate it.
But like all other mechanical parts, the multiport valve will eventually fail. Sometimes, breakdowns can be fixed. Other times, it makes more sense to replace the valve instead of repair it. First of all, you need to learn certain features of your filter because multi-port valves are not interchangeable among filter models or brands or filter type.
