How to Clean a Venturi Nozzle on a Water Softener

When the venturi nozzle on your water softener gets too dirty, your water softener will stop working properly. This occurs because these parts are part of the mechanism that pulls in the salty water (brine) to clean out hard deposits trapped by the resin beads--this process is called brining. If this stage of the softening process is interrupted, naturally your water softener's efficiency will diminish. If your water softener appears to be having problems, try cleaning the venturi nozzle before spending money on an expert. Cleaning these parts is simple and does not take much time.

  1. Set two small bowls nearby. Fill one with warm soapy water and leave the other one dry.

  2. Hold the nozzle assembly with one hand and slowly turn the cap. Normally, you must turn the cap counterclockwise to loosen it, but if this does not work, try turning it clockwise. Remove the cap and set it and the other small parts aside in the dry bowl so you can keep track of all the parts.

  3. Place the nozzle, the venturi and the venturi housing in the bowl of soapy warm water. Stir lightly with your fingers to agitate the water.

  4. Gently clean these parts with a small soft-bristled brush and rinse it under a faucet.

  5. Check other parts of the assembly for dirt and grime. Clean and rinse these before re-assembling or your work may soon be undone (if dirt from these migrates to the venturi and nozzle).


  • Avoid abrasive cleaners, as these may damage the parts.
