I have a Autotrol 255/460i valve on my water softener. Over the years it has been working great, but one problem that I found is that I never know when it has regenerated. Is there a way to determine this?
Answer: There is an easy way! Tie a piece of string (or dental floss) around the camshaft that is located on the top of your control. Leave a long tail hanging down in a place where it will not interfere with the operation of the metallic valve tabs that are found below the cam. Check the string in the morning – if it is wound around the camshaft – the unit has regenerated during the night. Hope this helps.
