Softener produces a rotten egg or sulfur smell in the softened water.

Safety: Use only disinfectants approved for potable water and follow label instructions.

Steps:

• Shock disinfect: Perform a resin tank disinfection using AquaClean-approved sanitizer or household bleach at recommended dosage.
• Clean brine tank: Empty the brine tank, scrub interior surfaces, rinse thoroughly, and refill with fresh salt.
• Increase regen frequency: Adjust settings so the AquaClean softener regenerates more often, reducing stagnation.
• Pre-treatment: If source water has high sulfur, consider installing an iron/sulfur filter ahead of the softener.

If odor persists, the resin bed may be permanently fouled and require replacement.
