SoftPro water softener is not softening water (hard water at faucets) even though it appears to regenerate normally.

Safety first: No special hazards beyond normal plumbing. If you open plumbing, shut off water and relieve pressure first.

• 1. Check bypass valve: Confirm the SoftPro bypass is in the Service position. If in Bypass, move it to Service and retest water hardness after a few minutes.
• 2. Test water hardness: Use a hardness test kit on water before and after the softener. If both are the same, the softener is not exchanging hardness.
• 3. Verify programming: Confirm hardness, capacity, and regeneration frequency are correctly set for your water conditions and household size.
• 4. Inspect resin condition: If the unit is older or has been exposed to iron, chlorine, or hot water, the resin may be fouled or damaged. You may notice resin beads in fixtures or a sulfur smell. Consider performing a resin cleaner treatment or replacing the SoftPro cation resin bed.
• 5. Check for internal bypass: Worn seals or a cracked distributor tube can allow hard water to bypass the resin. This typically requires removing the valve head and inspecting/replacing the piston and seal kit and checking the riser tube.
