Why is my water still hard with the PURIKOR Control Unit?
- MMelody StephensAug 14, 2025
If the water remains hard when using the PURIKOR Control Unit, several issues could be the cause. Ensure the by-pass valve is closed. Check the salt level and add salt to the tank if it's empty. Inspect the injector/screen for any blockages and clean if necessary. Verify that water is flowing correctly to the brine tank by checking the brine tank refill rate. If you have hard water in the hot water tank, repeating the flushing of the hot water tank might be required. Also, check for leaks between the valve and central tube, inspecting for cracks or damaged o-rings and replacing any faulty parts. Finally, an internal valve leak could be the culprit, requiring replacement of the valve seals, spacer, and piston assembly.
