Galvanised plumbing fittings have several advantages that make them a viable option for certain applications:

Corrosion Resistance: The zinc coating on galvanised fittings acts as a protective barrier, preventing rust and corrosion

Durability: Galvanised fittings are strong and can withstand high water pressure, making them suitable for various plumbing systems

Cost-Effective: Compared to other materials like copper, galvanised fittings are generally more affordable

Versatility: These fittings can be used in both indoor and outdoor applications, including cold water systems and outdoor plumbing

Long Lifespan: With proper maintenance, galvanized fittings can last for several decades

However, it’s important to consider some potential drawbacks:

Internal Corrosion: Over time, the zinc coating can wear off, leading to internal corrosion and reduced water flow

Not Suitable for Hot Water: Galvanised fittings are not ideal for hot water systems as the zinc can deteriorate faster under high temperatures
Heavy and Rigid: These fittings are heavier and more rigid compared to alternatives, making installation and repairs more labour-intensive
