Softener causes noticeable pressure drop or low water flow in the home when in service.

Safety first: If you need to disconnect plumbing, shut off water and relieve pressure first.

• Compare in bypass vs service: Place the Tier1 softener in BYPASS. If pressure improves significantly, the restriction is within the softener.
• Check bypass and shutoff valves: Ensure all valves are fully open and the bypass is not partially engaged.
• Inspect inlet screen: Many Tier1 valves have an inlet screen. Shut off water, remove the inlet fitting, and clean any sediment from the screen.
• Regenerate and backwash: Run a manual regeneration and ensure a strong backwash flow to flush the resin bed. Observe the drain line for heavy sediment discharge.
• Resin condition: If flow remains poor, the resin may be fouled or compacted. Consider replacing the cation exchange resin and checking the distributor tube for blockage.
