Possible Causes

Brine refill time set too long, Leaking refill valve, Incorrect salt dosage setting, Brine line siphoning

How to Fix / Troubleshooting

Safety first: Avoid overfilling the brine tank with water while testing.

  • Review settings: Check the programmed salt dose or brine refill time against Monarch specifications for your model and resin size. Reduce if set too high.
  • Check for continuous refill: In service mode, listen for water entering the brine tank. If water flows when it should not, the refill valve is leaking and needs service.
  • Inspect brine line routing: Ensure the brine line does not create a siphon effect that could draw extra water into or out of the tank.
  • Monitor after adjustment: After changes, observe salt usage over a few cycles to confirm normal consumption.
