Zinc-plated steel is generally not recommended for plumbing, especially for carrying drinking water or in wet or corrosive environments.
Zinc plating provides some corrosion resistance but is not sufficient for long-term exposure to water, particularly in plumbing systems where pipes may be continuously wet or exposed to water with varying pH levels.
Over time, the zinc coating can corrode and expose the underlying steel, which will then rust and deteriorate.
Zinc-plated steel is particularly vulnerable to corrosion when used with hot water, which can accelerate the breakdown of the zinc coating and lead to rusting.
In drinking water applications, zinc can leach into the water supply. While zinc is not as toxic as other metals, it can still pose a health risk if consumed in large quantities over time.
Better Alternatives:
- Copper: Commonly used in plumbing due to its corrosion resistance, durability, and safety for drinking water.
- Stainless Steel: More corrosion-resistant than zinc-plated steel and suitable for both potable water and corrosive environments.
- PEX or PVC: Plastic pipes are often used for water supply lines due to their affordability and resistance to corrosion.
