Material Compatibility
Dissimilar Metals
Installations containing mixed metals should generally be avoided, as galvanic corrosion may occur when dissimilar metals are connected directly together.
Where mixed-metal systems are unavoidable:
- Follow the Water Regulations Guide.
- Apply recognised engineering best practice.
- Consider suitable isolation measures where required.
