Introduction
You can often fix water softeners by checking the brine tank for salt problems or simply cleaning the resin bed or several other key parts. All are easy to do and you might avoid the expensive service call.Overview: Check the Control Settings
Is your soft water not so soft anymore? You can often fix the problem yourself. However, if you have an older softener (20 years or so) and none of these fixes work, it may need replacement ($500 and up).
All softeners, whether they have one or two tanks, work the same way. As cold water flows through the resin tank, the mineral content—the hardness—is removed because the minerals stick to thousands of resin beads. When the softener recharges, the flow of fresh water is stopped while salty water from the brine tank is sucked into the resin tank, where it dissolves the accumulated minerals and is flushed down the drain.
Before you tear apart your softener, check the control settings—especially after a long power outage. The timer clock has to show the right time so that the resin tank is cleaned and recharged when no one is using water (usually early morning).
Also, make sure the hardness setting is still correct—well water hardness can change over time. Bring a small container of your water to a water softener dealer for a water hardness test, then check the results against your settings.
Note: Set the water supply to “bypass” before working on the softener. And run the hot water after you turn the softener back on to flush out any hard water.
