The answer to 'why is my water softener leaking water' is that there are several common causes, including a faulty valve, worn seals, or issues with the brine tank. Water softeners use water pressure to regenerate the resin beads, and any leaks in the system can cause water to continuously drain.
Some of the most common symptoms of a leaking water softener include water pooling around the unit, low water pressure, and an increase in your water bill. To fix a leaking water softener, you may need to replace worn gaskets or seals, adjust the valve settings, or in some cases, replace the entire unit.
