I recently rebuilt the venturi on a 10 year old softener. I was amazed at how
small the actual water passage was and how some very small pitting in the gasket
totally killed the ability of the venturi to operate correctly.

I'd suggest you see if you can buy a new venturi/gasket kit and replace those
parts. Pay particular attention to order of assembly. If a gasket or button is
installed upside down, the system will not work...
