Filters are vital components for your swimming pool! Water will pass through the filter (which is filled with Sand or Glass media). The fine particles that the skimmer basket can't remove are trapped in the media. Once these particles build up in the filter this then increases the pressure in the system so you need to remove this debris by a method called backwashing. Using the Multiport Valve (which is either positioned on the side of the filter (side mount filter) or on the top of the filter (top mount filter)) to change the flow of water through the filter the water is sent back up through the media down the waste line. The media is then rinsed and then the multiport valve can be set back to filter. So it is very important to get a filter with a quality Multiport Valve as it will get a lot of use!
