I have a kenmore 300 series softener. It's leaking where the bypass valve connects to the valve assembly on the underside. Circled in the picture is where it's leaking but the under side that you can't see. I ordered new washers and clips. It did not fix it. I can't see anything cracked on the underside. I can only get those rings off by breaking them so I'm waiting to take it back apart. Any suggestions before I call in backup?
