So you own a home that is still equipped with the same water pipes from when the home was first built. In that case, you are looking at Galvanized Steel. Although people thought years ago that the amount of zinc within the pipes would be harmful to them, it actually isn’t. However, over that time frame you can be guaranteed the pipes have a lower flow of water coming through, due to rust and the inside of the pipes being corroded. If a water softener was used throughout the years, then the corrosion may be slightly less severe. Then of course you also have to have the concern of asbestos being present if nothing has been touched during the decades. With water pipes having an age of 60 years or more, it is time to replace them.
