Water Softener: Why does my water softener leak water?

Loose water line connections, cracked water-carrying components or worn rotor valve seals can cause water softener leaks. Tighten water line fittings if they leak. Check for cracks in the bypass valve assembly and replace it if it's cracked and leaking water.

Check the rotor valve for damaged and replace the rotor valve if it's cracked and leaking. If the rotor valve is okay but its seals leak water, replace the rotor valve seals.
