    3rd year with the sand filter/salt chlorinator combo. I love it! I just started my pool a week ago for the third year. It seems to work fine while it's filtering for a few hours but then when it goes to auto filter the next day there is next to no flow. I decided to back wash it again and then...

    Brand new sand filter question

    I have a brand new Intex 20 ft above ground pool with a sand filter. When I operate the filter it runs good for about 45 min and then the water flow trickles down to nothing.

    Decreasing flow rate

    I just opened my pool a few days ago and noticed that the water flow rate decreases significantly 2-3 hours after I started the pump. (Hayward S244T sand filter installed in 2012) - Running a backflow and rinse will result in normal water flow for another 2-3 hours. - Because the sand has been...
