How to Fix / Troubleshooting
Safety first: Ventilate the area. Do not mix bleach with other cleaners. Wear gloves and eye protection.
Step-by-step:
- Identify source: Test raw water for sulfur odor. If present before the softener, additional treatment (aeration or oxidizing filter) may be needed.
- Sanitize brine tank: Place the AquaUnique softener in BYPASS, empty the brine tank, and clean it with a mild bleach solution. Rinse thoroughly.
- Sanitize resin bed: Follow AquaUnique instructions to sanitize the resin tank using an approved disinfectant (often diluted bleach) during regeneration.
- Increase usage: Avoid long periods of no water use; stagnant water can worsen odors.
When to call a technician: Persistent sulfur odor may require specialized treatment equipment and professional water analysis.
