I keep having to turn the our pump off and put it on the rinse cycle for a few mins to get the volume back on the filter setting. Not all the time but way more than we ever had in previous years. I know it’s plumbed right and new sand this year, not over max when I filled the filter up. Is it possible it’s just collecting that much junk? I quit using hair nets because I thought that was the problem, even tho with daily changes they weren’t that bad.
