Today while running my 360xl it looked like I was putting down to much Flex ice. I went and checked my meter and it was metering even when I wasn't pulling the trigger. I checked out my water box and it was foaming up and smelled like Flex ice. I then ran a bunch of water through my open ended line to empty out the water box and filter new water in. I finished the job rinsing with just fresh water and then post bonneted with encapuguard green to neutralize. So after some research I think my diaphragm in my chemical pump may have a hole in it. Has anyone else had this problem? Is there a rebuild kit? Does everyone rinse fresh water through there metering system at the end of the day? Sorry for so many questions, just trying to do it right.
