Water Softener Troubleshooting Too much Water in Brine TankUpdated a day ago
Noticing a high water level in your brine tank? This is one of the most common signs that your water softener isn’t functioning properly—and fortunately, it’s often easy to diagnose with a bit of guidance. In this video, we break down the most likely reasons your brine tank is overfilling, starting with the simplest fixes first. Whether it's a loose brine line, a salt bridge, or a more advanced issue like a clogged injector or faulty circuit board, we’ll help you identify the problem step-by-step so you can get your system working as it should.
Common Causes of High Water in a Brine Tank:
Detached brine line: If the brine line has disconnected from the float, it can’t draw brine—only fill. Reattach the line to fix.
Salt bridge: A hardened layer of salt can block water movement. Use hot water to break it up or check out our video on salt bridge removal.
Clogged or frozen drain line: A blockage or kink can prevent brine draw. Straighten or thaw as needed.
Blocked drain line flow control: Debris buildup can restrict flow. Remove and clean the control.
Debris in the brine level control valve/float: Disassemble and clean the valve, especially the base, where salt buildup is common.
Dirty brine line flow control: Dirt can be pulled into the control and clog the hole—just clean it out.
Clogged injector system: The injector creates suction for brine draw. Soak the injector and screen in CLR or Iron Out, and use a wooden toothpick to clean the orifice.
Malfunctioning timer or circuit board: If settings won’t change or the display is blank, the board may need to be replaced.
Worn spacer stack or pistons: If water is visibly moving inside the valve during service mode, the internal components may need replacing.
