Service Wrench for Clack WS1

Clack WS1 Service Wrench

I had some issues with my water softener that require me to clean the stack. I used the screw driver method to access it. It work, but was a little tedious. I still couldn't get the softener to work, so I figured I would change the stack. I ordered a Service Wrench with the new stack. A well spent $15. It was much easier and quicker to open the head with the wrench vs a screwdriver.
