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.
