Culligan Good Water machine - model AC30 - cannot get the polishing filter off to replace. Do I cut the line or how do I remove it?

Hi Stanlyn...

If you are talking about the smaller inline filter seen in the picture below then you need to shut off the water and then push the small plastic sleeve (blue plastic on filter below) in while pulling the tubing out.

You should use a pair of pliers to push in on the blue plastic sleeve while at the same time pulling on the tubing to remove it... see image below.

Do this to both sides of the filter to dislodge and replace.

Let me know if it's something else, OK?

Thanks. I'll try that.
