Tired of cleaning sprinkler nozzles? We now have a TIME SAVING solution for having to clean nozzles with a straight pin! JUST PUSH A BUTTON! The Drop Nozzle Filter was designed by a farmer in Oklahoma that had clogging problems. He now cleans his Drop Nozzle Filters once a year. Instead of spending all day with a straight pin in his hand, He takes a quick walk down the pivot and PUSHES A BUTTON. The filter shown in our pictures, screws into the bottom of the filter housing with a coarse thread. So even under the worst clogging conditions its as simple as, three turns out, tap tap, three turns in. Done. Questions? Contact Gavin Nash DropFilterPro@gmail.com (806) 319-0678
