What are galvanized pipes?
Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. These types of piping were commonly installed in homes built before the 1960s.
The galvanized pipe was invented as an alternative to lead pipe for water supply lines. Today, however, we have learned that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside.
These pipes can easily become blocked and start to corrode, causing the water pressure to go down as well as other hidden problems.
As there are a lot of aged homes in and around Sydney especially, galvanised pipes have become quite a problem.
What do galvanized pipes look like?
When first installed, galvanized pipes look similar to a nickel in colour. But as it ages, galvanized pipes appear much duller, lighter, or darker, depending on its environment.
We’ve also seen houses where the water pipes have been painted, so it can be difficult to tell at first glance and why you need a licensed plumbing professional to help diagnose the issue.
Problems that can occur with galvanized pipes –
Low Water Pressure
Due to the restriction of the line, corrosion in galvanized pipes can cause lower water pressure throughout your home.
Uneven Distribution of Water
If some of your taps have low water pressure, but others don’t, this could be a symptom of galvanized pipes. Corrosion can build up unevenly.
Discoloration of Water
Galvanized pipes can release iron and cause discoloration. A clear indicator of this is a brown stain on a porcelain sink.
Given enough time, galvanized pipes will rust through and cause more damage to your home.
If you are in a home with galvanized plumbing, you may need to budget for repairs or replacement, as these pipes have a limited lifetime.
