How do you clean a salt tank on a water softener?

Cleaning the salt tank (also known as the brine tank) on your water softener is important for optimal performance. Here's how to do it:

1. Initiate a Manual Regeneration Cycle: This will draw down the water level in the brine tank, making it easier to clean. Consult your water softener's manual for instructions on how to start a manual regeneration cycle.

2. Bypass the Water Softener: Before proceeding, put your water softener into bypass mode. This prevents water from entering or exiting the unit during the cleaning process.

3. Remove the Salt: Scoop out as much of the salt as possible. If it's caked together, you might need to break it up with a tool like a large screwdriver. Discard any old or contaminated salt.

4. Clean the Tank:

   • Water and Bleach Solution: Add 1-2 gallons of water to the brine tank.
   • Add Bleach: Add ¼ cup of unscented household bleach to the water. Do not use scented bleach.
   • Scrub the Tank: Use a brush (a long-handled scrub brush works best) to thoroughly clean the inside of the tank, removing any accumulated sediment, salt buildup, or grime. Pay particular attention to the bottom and sides.
   • Clean the Brine Valve: It's beneficial to run water over the brine valve and float assembly during cleaning to remove any salt buildup.

5. Rinse the Tank: Drain the bleach solution and rinse the tank thoroughly with clean water until all traces of bleach are gone. Multiple rinses might be necessary.

6. Inspect and Clean the Brine Well (If Applicable): Some water softeners have a brine well – a smaller cylinder inside the tank that houses the float valve assembly. If yours does, remove it and clean it separately.

7. Reassemble and Refill:

   • Replace the brine well (if applicable).
   • Add new salt to the tank, filling it to the recommended level (usually about half to two-thirds full).
   • Return the water softener to service (take it out of bypass mode).

8. Initiate a Manual Regeneration Cycle (Again): Run another manual regeneration cycle to flush the system and ensure everything is working correctly.

Why is Cleaning the Salt Tank Important?

• Prevents Salt Bridges: Salt can form a hard crust (a "salt bridge") that prevents the salt from dissolving properly, reducing the softener's effectiveness.
• Removes Sediment and Debris: Dirt, minerals, and other debris can accumulate in the tank, hindering performance.
• Prevents Clogging: Buildup can clog the brine valve and other components.
• Maintains Water Quality: A clean tank helps ensure the water remains clean.

How Often Should You Clean the Salt Tank?

It's generally recommended to clean the salt tank at least once a year, or more frequently if you notice problems like salt bridging or reduced water softening performance.
