If you live in a house that was built before 1960, there is a good chance that your home's plumbing has galvanized plumbing, if no upgrades have been made within the last 45 years the least.

How to Know if there are Galvanized Pipes in your House

If you are not sure what kind of pipes are in your home, there are some easy ways to tell which type you have by using a heavy-duty magnet and scratching a little off the surface of them in different areas of the piping with a tool. The reason to check in different regions of the pipes is that there could be upgrades in just a few places and not the entire home.

Once you have scraped the surface, the color of the pipes should be as follows:

  • Galvanized Steel Piping – This shows a silver-gray shade, and when you put the heavy-duty magnet up to it, it will attach to it.

  • Cast Iron Piping – This is mainly used for wastewater removal from the residence, but has also been used in other parts of older homes. The color of cast iron is black, and a magnet will stick to it. Cast Iron has a very long lifespan, but problems can start to happen when the pipes deteriorate. It is at this point when having issues with the tubes or breakages that it can end up being very costly for the homeowner for clean up and repair or replacement.

  • Copper Piping - Presents as a copper coin, and the magnet does not attach to it.

  • Lead Piping – This will is easy to scrape and be silver-gray, the heavy-duty magnet will not adhere to it, but due to possible health issues, it is recommended that if you do have this type of piping, it also needs replacing as soon as possible.

  • Plastic Piping – The shade of this will be either white or ivory, and there will be no pull on the magnet.

  • Brass Piping – Will be a color of yellow-gold and the magnet will not stick to it.

When & Why you Should Replace?

The lifespan of galvanized pipes is no longer than fifty years, and since they have not been utilized since the 1960s, they have already passed their expected lifetime. If you have any galvanized pipes within or outside of your residency, then you need to have them checked and replaced as soon as possible by qualified professionals just like JCN Plumbing, a licensed and Insured family-owned plumbing company, based in Miami, FL.

Some of the signs that will indicate if the galvanized pipes are having issues is if they are rust or brown colored running water after the outlets have not been in use for a while, decreased water pressure, rusting on the outside of the pipes or at the joints.

blbloGalvanized steel pipes were covered with Zinc to help keep the product from deteriorating, but with time they start crumbling from within, due to the rust and calcium build-up that begins to form, making the inside width of the pipe smaller. The more the rust and particles collect within the piping, the less room there is for water movement. The decrease in water flow helps to increase the chances of having the piping leak or break from the pressure that can build up behind the water outlets. When you have pressure built up, you can then end up with water damage that can be very costly for the clean-up, as well as if it is anywhere in or near the foundation it can compromise the foundation.

It is also a good thing to know what kind of piping is used from the house out to the water source (whether it is a public water system or a private well). It is essential to know if the external piping or connections to the water system has been replaced at any point because galvanized and cast iron tubing was not only used for residential housing, but for many central water systems for municipalities.

If your residence had an upgrading done to the pipes but the city’s system has not, then you could have lead contamination coming into your home. It is also a good idea if there is any doubt about lead contamination, to get a water sample tested.

If you do find that your home has galvanized pipes, your insurance may not cover any problems that could appear, due to the age of the pipelines. So it is advisable to have your plumbing evaluated before it is too late.
