Looking for AquaMaster parts?

In the United States, AquaMaster water softeners are sold under the WaterBoss brand. If you're replacing a part on an AquaMaster system, the most important thing to match is the part number.

If your existing part is #54521, this is the correct genuine OEM replacement whether your system is branded WaterBoss or AquaMaster.
