How do I access & clear debris in Backwash Restrictor in a Culligan Mark 80 Water Softener?

You will need a bucket. Where the drain line comes out of the valve there is a clip to hold the drain line onto the valve. Hold the bucket up to it, pull the clip out, pull the drain line off, and into the bucket to catch water coming back from the drain line. There will be a rubber button inside to pull out with a small center hole. There will be debris in there. Remove the debris and replace the button (drain line flow control). Regenerate your water softener three days in a row for soft water then run the hot water until cold.
