Identifying a Flooded Water Softener Brine Tank

When a water softener isn't working well or leaving stains behind, you may have a flooded brine tank. A number of things can cause a brine tank to overfill: start with some troubleshooting before having your system inspected.

Why Do Water Softener Brine Tanks Flood?

If any parts involved in the water softening process get clogged, the brine tank will flood.

Most brine tanks have a safety float valve inside a separate tube in the tank, and if that valve can't operate, too much water will accumulate in the tank, so the water softener can't clean itself and your water will get harder over time.

How to check for a flooded brine tank

  • Check your water softener to see if the low salt light is on. If your water softener doesn't have a low salt light, take the lid off the brine tank and look inside. Most brine tanks are made to hold 250–300 pounds of salt. You want to keep the salt level above the water level.

  • Look at the brine tank to see if it's full of water. Check the manual for your water softener to see whether or not your system is supposed to have water in the brine tank. Depending on the system you have, it may need to be completely dry, have approximately 6" of water in the base of the tank, or, if your system has a platform, it may need to have 1–2 inches of water above the platform. Having far more water than your tank requires means that the system has flooded.

If a flooded brine tank doesn't seem to be the culprit, consider other reasons for hard water.

What to Do if Your Water Softener Brine Tank Is Flooded?

If a flooded brine tank is traced to a faulty float valve, the problem will not resolve itself. You may need to call in an expert to find the source of the issue and repair it.
