Possible Causes
High inlet pressure, Lack of water hammer arrestors, Fast-acting Ecowater valve causing pressure spikes, Loose plumbing supports
How to Fix / Troubleshooting
Safety: Sudden pressure surges can stress plumbing; address promptly.
- Check pressure: Measure inlet pressure. If high, install or adjust a pressure reducing valve.
- Secure pipes: Inspect visible pipework and secure any loose sections with proper clips or brackets.
- Install hammer arrestors: Fit water hammer arrestors near the Ecowater softener or at problem fixtures to absorb shocks.
- Adjust regeneration time: Schedule regeneration for night hours when fewer fixtures are in use to minimize perceived noise.
