If you have a home with galvanized plumbing, it’s important to know how long the pipes will last before considering whole house repiping. The average lifespan of galvanized pipe is about 50 years. However, if you live in an area that experiences high levels of corrosion, the life expectancy can be much shorter.
The first sign that your galvanized pipes are wearing out is rust. Rust forms on the inside and outside of the pipe, which makes the pipe look dirty. As the rust builds up over time, it becomes more difficult for water to flow through the pipe. This causes the pipe to become clogged and slows down water flow throughout your house.
The second sign that your galvanized piping needs to be replaced is when the pipe starts leaking. If you notice any leaks around your home, then it’s likely that your galvanized pipes need to be replaced. Leaks occur because the zinc coating has worn off or been damaged by corrosion. Once the zinc coating wears off, the steel core underneath begins to corrode. You should contact a professional plumber immediately if you see any signs of leaks or rust on your galvanized piping. A professional plumber can easily remove the rust from your pipes without causing damage to them.
