What is Galvanized Pipe

Galvanized pipe is a form of steel pipe that is coated with zinc, making it immune to the negative effects of rust and corrosion.

How Does Galvanized Pipe Affect Water Quality?

Galvanized pipes have raised a great deal of water quality concerns due to their impact on the composition of the water. Zinc, a vital component of the galvanizing process, can gradually erode and mix with water, leading to elevated levels of this metal in the water supply. This could trigger a host of health problems, including gastrointestinal upset, vomiting, and other digestive ailments, all of which are linked to excessive zinc consumption.

Are There Any Regulations Governing the Use of Galvanized Pipes for Water?

The use of galvanized water pipes in the United States is not subject to any particular regulatory oversight. However, certain states and local jurisdictions have established their own criteria regarding acceptable zinc concentrations in drinking water. Therefore, it is crucial to contact your local health department to determine if there are any provisions in your locality regarding this matter.

What Are the Pros and Cons of Using Galvanized Pipe for Water?

Like any material, there are both pros and cons to using galvanized pipes for water. Here are some of the main advantages and disadvantages to consider:


  • Durable and long-lasting: Galvanized pipe is strong and durable, which makes it an ideal choice for water pipes. With proper installation and maintenance, it can last for many years.
  • Affordable: Compared to other materials, galvanized pipe is relatively inexpensive, which makes it a popular choice for many homeowners and contractors.
  • Widely available: Galvanized pipe is widely available and can be found at most plumbing supply stores and home improvement centers.


  • Zinc leaching: Over time, the zinc coating can dissolve into the water, which can result in high levels of zinc in the water. This can have negative effects on health and water quality.
  • Rust and corrosion: Although galvanized pipe is protected from rust and corrosion, it is not immune to these problems. Over time, the zinc coating can break down, which can lead to rust and corrosion.
  • Limited lifespan: While the galvanized pipe is durable, it is not as long-lasting as other materials, such as PVC or copper.

Should You Use Galvanized Pipe for Water?

The choice to use galvanized water pipes is based on several considerations, such as financial constraints, local legislation, and individual inclinations. In cases where safety and water purity concerns are paramount, alternative materials such as PVC or copper may be considered more appropriate. Conversely, in situations where cost-effectiveness and durability are essential, the galvanized pipe could be a feasible option.


The galvanized pipe has both pros and cons when it comes to using it for water. While it is affordable and widely available, there are concerns about its impact on water quality due to the potential for zinc leaching. It’s important to carefully consider all of the factors and regulations in your area before making a decision.
