Yes. You should clean the brine injector valve at least every 1 year; preferably every 6 months. Otherwise called the venturi valve, the brine injector has a mesh screen that prevents dirt from getting into the brine tank. This screen clogs up over time and requires cleaning out. You’ll usually need to bypass the softener then run it through a regeneration cycle before you open the cap or cover to reach the valve. Check your user manual if you’re not sure of the location of this valve within your water softener.
