in your sand filter there are parts that are called fingers which have like screens in them. it sounds like you have a hole in one of yours. I had this problem last year. There are plastic parts in the bottom of the sand filter that are called laterals. They are designed the same way as spokes on a wheel. Drain the sand out of the filter and unscrew and check each lateral (I think our filter had 8) for cracks or holes. 2 of mine needed to be replaced. This wasn't hard (just a little time consuming), and the parts weren't expensive.

∙ 15y agoIf sand from the filter is ending up in the pool then the laterals are getting worn. These are at the bottom of the sand filter and should only allow water to pass. A: You have a bad lateral(s). You need to remove all of the sand from the filter in order to get to the laterals. Some laterals either unscrew or click or press into place. Once the lateral is repaired replace the sand with new sand using a #20 grade filter sand. k

∙ 14y agoAll sand filters have a apparatus inside used to stop the sand from blowing back into the pool while letting water pass through. This is called the lateral system. It consists of a center standpipe, a hub assembly and the individual laterals. Any one of these three parts may be cracked and allowing sand to pass through. This requires opening the filter and removing the sand. Then carefully examine the lateral system for any cracks or holes. If any are found, bring ALL the pieces plus any info off the tank label to your local pool supplies dealer and they should be able to supply or order the parts. Other ways might include a bad spider gasket inside your filter valve or the fact that a sand filter will generally level itself out to the proper amount of sand when initially filled.

Many people mistake "mustard algae" as sand in their pool. Does the sand briefly disappear when you run a pool brush over it? Mustard algae resettles quickly and looks very much like filter sand. We have helped many customers with this problem. Also, if there is truly sand in the pool and you have replaced the laterals, check for any leakage of air around the filter. You may hear or see cavation in the pump when it is shut off.
