1. Regularly Check Salt Levels: Monitor salt levels and top them off as needed.
2. Clean the Brine Tank: Clean the brine tank every 6-12 months to prevent clogging.
3. Check and Replace the Filter: Regularly inspect and replace the filter to ensure optimal performance.
4. Schedule Annual Maintenance: Consider scheduling annual maintenance with a professional to ensure your softener is functioning correctly.

Ensure the drain hose is straight and free of obstructions. If the hose runs into a floor drain, make sure there is an "air gap" and that the end of the hose isn't submerged in water. Step 4: Reset the Control Board

Here are the top four culprits for an overfilled tank.

The most common culprit is a clog in the nozzle and venturi assembly. This component creates the suction (vacuum) needed to pull brine out of the tank. If it’s clogged with sediment, salt crust, or iron, the water goes into the tank during the fill cycle but never gets sucked out. 2. Salt Bridging

The Cons (Honest Reality Check)

❌ Physical Footprint: The brine tank plus the 40” tall mineral tank will take up about 4-6 square feet of floor space. It won’t fit in a small utility closet.
❌ Installation Weight: A “full” tank weighs over 100 lbs when filled with wet resin. You’ll need a dolly and two people to move it.
❌ Cost: Expect to pay $800–$1,500 for a quality Fleck-based 40278 full system (cheaper off-brands exist, but avoid them).
❌ Overkill for Small Homes: If you have 2 people and moderately hard water, this unit would be inefficient (salt can harden into a bridge between regenerations).
