How to Replace the Venturi in a Water Softener

 

file

This step-by-step repair guide gives instructions for replacing the venturi in a water softener. The venturi draws brine into the resin tank during the regeneration cycle. A damaged venturi can’t move brine into the resin tank to regenerate the resin beads, and the water won’t be softened. If the venturi is damaged, replace it with a manufacturer-approved replacement part . For DIY repair guides for other appliances, see our Repair Help section.
