Fits WaterBoss 180, 380, AMS 700, AMS 900, and AMS 950 water softeners.

The Injector Assembly is a critical component of your water softener's control valve. It creates the suction needed to draw brine from the salt tank during the regeneration cycle, allowing the resin bed to be properly cleaned and recharged. A clogged, worn, or damaged injector assembly can prevent your softener from regenerating correctly, leading to hard water and reduced system performance.
