How Do You Change The Sand In A Swimming Pool Filter?
1/ shut down the filter/pump. 2/ remove the drain cap on the filter bottom 3/ remove the multiport from the filter top and any associated plumbing. It justs lifts straight up after you’ve removed the collar. 4/ The easiest way to remove the sand is with a wet / dry shop vac. Be careful not to move the central stand pipe, you could break it. Once the sand is out, remove the lateral assembly. It looks like a wagon wheel. The lateral fingers will either fold up ( Hayward filter) or unscrew ( Jacuzzi or Sta Rite). Inspect those parts for damage or wear and replace as needed. 5/ Re install the laterals. Centre them in the tank and put a paper coffee cup over the standpipe hole. This stops sand that you pour in from going down that pipe. You don’t want it in the laterals. Carefully pour in the required amount of new silica sand. I suggest using silica since not only is it readily available and cheaper , it’s also proven. Other alternatives aren’t. Other media types that may possibly be used
