Softener causes a noticeable drop in water pressure throughout the house.

Safety first: Place the softener in bypass to temporarily restore normal pressure. Shut off the water supply and relieve pressure before removing plumbing connections.

Steps to check:

• 1. Compare pressure in bypass vs. service: If pressure is normal in bypass but low in service, the restriction is within the softener.
• 2. Check bypass valve: Ensure the bypass valve is fully in the service position and not partially closed.
• 3. Clean inlet/outlet screens: Remove the control valve and inspect any inlet/outlet screens or strainers. Clean any debris and reinstall.
• 4. Evaluate resin condition: If the resin is heavily fouled or compacted, it can restrict flow. Resin replacement may be required.

When to call a technician: For resin replacement or if you suspect the softener is undersized for your plumbing, consult a water treatment professional.
