Fleck Water Softener Troubleshooting Tips

Even though Fleck water softeners are known to be incredibly durable and easy to use, you may from time to time, run into a small problem. Knowing how to troubleshoot this problem on your own can save you a lot of time and frustration when dealing with it.

Sometimes, owners install their new Fleck water softener and they are frustrated because they are still getting hard water when they run their water. This is generally a user error and not a problem with the softener.

It’s important to check and close the bypass valve and then make sure that the injectors or the screen aren’t plugged. These are the main issues that can cause this problem, although an internal valve leak is possible, although not very probable.

Another issue that can occur with a Fleck water softener is a loss of water pressure. When this occurs, then there is likely buildup of excess iron in the water condition or line. Simply cleaning out the line is the best way to handle this.

If your Fleck water softener is using too much salt, then it is generally caused by one of two problems. Sometimes, there is simply too much water in the brine tank. Cleaning the flow control can help to adjust how much water is in the tank and take care of this issue.

Another problem that can cause the use of too much salt is an improper salt setting, which is easily adjusted via the controls. Simply check the salt usage and setting and adjust them to match.

If there is a loss of resin through the drain line, then that is a sign that there is air in the water system. This may take a little more time to adjust, but can usually be easily handled. The first step is to make sure that the well system has the right air eliminator control so that the air can easily be removed. You will then want to check to make sure that the well is dry.

Softeners sometimes have problems drawing brine, which means that your equipment will not be able to work the way that it should. There are a few problems that can cause this issue, including a plugged drain line flow control, plugged injector, or plugged injector screen.

The drain line flow control and the injectors can easily be cleaned to fix this problem, but the screen will need to be replaced. If the line pressure is too low, then the softener won’t be able to draw brine. Users need to increase line pressure and keep it at a minimum of 20 PSI all of the time.

An internal control leak can also cause problems. This is rectified by changing the spacers and seals or even the piston assembly to help the equipment work correctly again.

Finally, some people report problems with the control cycling continuously. This is one problem that requires a spare part, as the water softener probably has a faulty timer mechanism. Simply replacing the timer is the best and fastest way to deal with this issue.
