Water Hammer Arrestors
Plumbing issues you are facing:
- Loud banging or thudding in walls when faucets shut off quickly
- Pipes shaking or vibrating when washing machine fills or stops
- Dishwasher causes hammering sound when water valve closes
- Knocking sounds when toilets finish filling
- Banging gets worse over time or with increased water pressure
- Single-lever faucets cause louder hammer than older two-handle types
- Recently increased water pressure and now pipes bang
- Concerned about stress and damage to pipe joints from repeated shocks
What D&H PLUMBERS fixes:
- Identify which fixtures or appliances cause the water hammer
- Locate optimal installation points near quick-closing valves
- Install properly sized arrestors (air chambers or piston-type)
- Secure loose pipes and add additional supports if needed
- Verify water pressure isn’t excessively high (adjust if needed)
- Test all fixtures after installation to confirm hammer elimination
- Install arrestors in accessible locations for future service
- Use code-approved devices designed for long-term reliability
