Possible Signs
- Blue-green copper staining
- Metallic taste
- Pin-hole leaks or corrosion
- Premature plumbing deterioration
Measure Before Treating
pH is only part of corrosivity. Alkalinity, hardness and other chemistry can affect treatment design and expected results.
Treatment
Acid neutralization can add alkalinity and raise pH when appropriate. System selection should account for water chemistry and household demand.
