Galvanized pipe is an iron or steel pipe that has been coated in a layer of zinc to protect it from corrosion. This is a popular construction material for outdoor pipes, but it is also used for some interior plumbing in older homes. The pipes corrode and rust over time, which can lead to poor water quality and low water pressure in the home. The good news is that homeowners can often identify a Galvanized pipe problem and have it replaced before they experience serious water leaks or damage to the house.
If you are concerned that your home’s piping might be galvanized, there is a quick and easy way to test it. A flathead screwdriver and a magnet will do the trick. First, find your water line and scratch it lightly with the screwdriver to see if a magnet sticks to it. If the screwdriver leaves a silver-gray mark, your pipes are galvanized. If they leave a white or ivory mark, they are not. If you do not have a magnet, but do have copper piping in the same place, you can still use the screwdriver test to confirm if your pipes are galvanized.
Galvanized pipes are a common sight in many older homes across the country. They were a popular choice for residential water piping before the 1960s. Galvanized supply pipes are typically spotted in unfinished areas of the basement or crawlspaces, and you may see them connected to copper lines before they connect to a sink, shower, or other fixture. The problem is that over time these pipes corrode and rust from the inside out, which can lead to low water pressure in your home and even more significant problems like pinhole leaks.
As the galvanized piping in your home ages, it can release accumulated lead into your tap water. This can be a major health concern, especially for children and pregnant women. Ingesting too much lead can cause a range of issues including fatigue, headaches, insomnia, constipation, abdominal pain, and decreased cognitive abilities.
There are a few telltale signs that it is time to replace your galvanized pipes. A sluggish drain, low water pressure in the home, and pitted rust spots on your pipes are all clear indicators that it’s time to invest in a new plumbing system.
In addition to being a safety concern, aging galvanized pipes can also cause costly plumbing repairs and reduce your home’s value.
