Drinking Water Part B - Check your materials
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. We now know that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside. This affects your water quality and could also potentially cause blockages.
If you know or suspect you have galvanised pipes, it's best to replace them with copper or polymer materials.(poly pipe)
We are very fortunate in Australia to have access to quality drinking water straight from the tap. If you have any concerns about your drinking water, you should first check your local shire council. Here they regularly provide updates on their water quality results.
