Question about Hayward SAND FILTER, PRO SERIES
To change the Media (sand, or zeolite sand replacement) you have to remove the top off the filter. There is a clamp that holds the top on. This is held together with two screws. If this is a top mount backwash valve you will have to remove the backwash valve. If you are lucky the person who installed it will have used unions so you can easily remove and replace it. If not you will have to cut pipes and re-plumb them when your done. If this is a side mount backwash valve then you should be just removing a top lid. Once you remove the top you can access the sand. You do not want to add sand without taking the old media out, and it doesn't do much good to replace only a portion of the sand. The label on the filter will tell you how much you need. Make sure you use #20 silica Pool Sand, and not any other type of sand. You can use Zeobest Zeolite sand replacement if you want a better filtration media. It cost a little more than twice the cost of sand, but you use half as much. It will filter better than cartridges, and almost as good as DE filters. You will want to "recharge" the media about once a year. this entails soaking the media in a solution overnight, then backwashing very well (another reason to use unions for the top). Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave good thumb rating if you found this helpful. Thanks, and good Luck!
