Experiencing constant draining from your water softener can be frustrating and costly, but this issue is relatively common and can usually be solved with a bit of troubleshooting. Below, we’ll explore the common reasons for a water softener draining issue and offer solutions for each.
Common Causes of Constant Draining
Stuck in Regeneration Mode
One of the most common reasons your water softener might be constantly draining is that it’s stuck in its regeneration cycle. If your softener’s motor or control valve fails, the system can become locked in this cycle, continuously flushing water down the drain. Checking the display on your water softener can help you determine if it’s regenerating.
If it’s displaying a countdown timer, the system is still in regeneration mode, which is normal. However, if water continues flowing once the cycle should have ended, a component might be malfunctioning. You can try manually resetting the regeneration cycle by pressing the “regen” button to force it to finish.
Clogged or Damaged Components
Another common issue is a clogged injector or drain line. These parts are crucial for managing the brine cycle, and if they become blocked with debris or mineral buildup, the water softener cannot draw brine properly, causing excess water to accumulate and drain. Cleaning or replacing the injector can resolve this. Additionally, any foreign objects stuck in the valve body could prevent the softener from working correctly. Inspecting these parts and removing debris often resolves the problem.
Valve or Seal Issues
Your water softener contains multiple pistons, seals, and valves that control the water flow. Over time, these components can wear out or become damaged, causing leaks or preventing proper movement, which leads to water continuously draining. If the issue lies with the valve, the motor may not be advancing properly, or the piston and seals might need replacing. You may need to replace the drive end cap if it’s a WaterBoss or AquaMaster system, or replace seals and pistons for Clack systems.
Brine Tank Issues
Another overlooked cause of constant draining can be issues within the brine tank. If the float in the brine tank is not functioning properly, it may allow too much water into the tank, which then causes the system to continuously drain to prevent overflow. Ensuring the float mechanism is working correctly can help stop unnecessary water drainage.
Time Settings or Power Supply Problems
Sometimes, simple issues like incorrect time settings on your softener’s control panel or a power supply problem can cause continuous draining. If the timer is incorrect, the softener may attempt to regenerate at odd times or not complete the cycle, causing it to drain excessively. Ensure the power supply is steady, and that the unit is properly plugged in.

Water Softener Troubleshooting Tips
To begin troubleshooting, first ensure the water softener is not currently in a regeneration cycle by checking the display and bypassing the system temporarily. If water stops flowing after bypassing, it confirms the softener is the issue. From there, check for any blockages or stuck components, such as clogged injectors or worn-out valves. Replacing faulty parts, such as seals or the motor, will typically solve the issue.
