What is galvanized pipe?

Galvanized pipes are steel pipes impregnated with zinc to prevent corrosion and rust. Galvanized pipes were installed in houses built before the 1970s and 1980s. When invented, galvanized pipes were an alternative to water supply pipes. In fact, it is learned that decades of water pipe exposure have caused galvanized pipes to rust after corrosion.

What does galvanized pipe look like?

Galvanized pipes look similar to nickel. But over time, galvanized pipes become darker and brighter, depending on their environment. Many houses with water pipes may be hard to tell at first glance.

How to confirm whether it is galvanized pipe?

If you can't judge by looking at the pipes, you can quickly determine whether they are galvanized. All you need is a flat-head screwdriver and a magnet. Find the water pipe and scrape the outside of the pipe with a screwdriver.

Comparing results:

copper

The scratched area looks like copper coins. The magnet will not stick to it.

plastic

Scratches will appear milky or black. The magnet won't stick to it

Galvanized steel

The scratches will have a silvery gray color. A strong magnet will stick to it.

Does galvanized tube contain health?

The galvanized pipe installed on the water pipeline during the initial period of liberation was immersed in molten natural zinc. Naturally occurring zinc is impure and these pipes are immersed in zinc containing lead and other impurities. Galvanized coating extends the service life of steel pipes, but adds a small amount of lead and other substances that may harm residents.

What other problems can galvanized pipes cause?

Low water pressure

Due to circuit restrictions, corrosion in galvanized pipes can cause low water pressure.

Uneven water distribution

Some faucets have low water pressure, while others do not. This is a symptom of galvanized pipes. Corrosion can accumulate unevenly.

Water discoloration

Galvanized pipes release iron and cause discoloration. A clear indication is brown stains on the ceramic sink.
