The little blue sprinkler filters which are in the heads of each of my pop-ups are getting filled with sand & dirt each year. I have a Rainbird system. I am having to unscrew each nozzel each spring & replace the little filters. Tis is quite a chore for a 60 yr. old granny. Has anyone tried their new 'Quick check Basket Filter" or any other filter they sell? The dealership here sold me a Y shape filter with a metal mesh screen in it last year. It attaches to my main line from the pump but is not working at all. I do have a well. Can anyone suggest a solution?
