Softener is very noisy during regeneration (loud banging or whistling)

Safety: High water pressure can be dangerous. If unsure, contact a plumber.

• 1. Check water pressure: Use a gauge on a nearby faucet. If pressure exceeds 80 psi, install or service a pressure reducing valve.
• 2. Secure plumbing: Ensure pipes near the softener are firmly strapped to walls or supports to reduce vibration.
• 3. Inspect drain line: Make sure the drain hose is not restricted, kinked, or submerged in standing water, which can cause whistling or chattering.
• 4. Consider water hammer arrestor: If banging persists, install a water hammer arrestor on the softener supply line.
