While older homes in the San Jose area come with a lot of charm and character, they do have a few maintenance challenges. One of the most common concerns that you should have as a homeowner is the presence of any galvanized steel plumbing in your home. Galvanized steel was standard in construction through the mid-20th century. However, over time, they’ve developed a variety of issues. Understanding what these issues are can help you to make the best-informed decision on how to move forward with your plumbing system.
What Are Galvanized Pipes in San Jose?
Galvanized pipes are simply steel pipes that are coated with a layer of zinc. The zinc was thought to help prevent rust and corrosion to extend the longevity of the pipes. Galvanized steel was commonly used in residential plumbing systems from the 1920s all the way through the 1960s and even into the early ’70s. While these pipes were great at the time for their enhanced durability and strength over other plumbing materials, they’re not completely immune to wear and tear.
Over decades of use, that protective zinc coating slowly erodes away. This exposes the steel underneath to water and oxygen. This is the perfect combination for unwanted corrosion that can compromise the structural integrity of your piping and even impact your water quality. With a lot of homes in the Bay Area dating to the mid-20th century, it’s pretty common to find galvanized piping in original plumbing systems.
Excessive Corrosion
One of the most significant problems that homeowners experience when it comes to galvanized piping is excessive corrosion. When water and oxygen react with exposed steel, it manifests as corrosion. This will reduce the flow of water through your line by narrowing the inside of your pipe due to the corrosion buildup. Flakes of the corrosion can actually break off and enter your water. This will not only discolor it, but also reduce its water quality level.
Corrosion is known to weaken the structural integrity of the piping itself. This makes it more likely to experience leaks and ruptures. Unfortunately, when it comes to galvanized piping, most of the corrosion that develops happens on the inside of the piping. You may not even realize there’s corrosion until there’s a severe burst in your line that leads to expensive repairs.
Sediment Buildup
As the inside of your galvanized steel piping starts to corrode, tiny flakes of rust and mineral deposits can break off. They can actually accumulate inside different areas of your plumbing system, which can lead to blockages and reduce water pressure. You may experience clogged faucets, appliances, or even showerheads due to this corrosion. Sediment creates premature wear and tear on your water heater.
It will discolor your water and even give it a metallic taste. Because San Jose is a region where water hardness can vary tremendously, some homes may experience severe deterioration due to hard water. Even worse, the hard water mineral sediments can build up inside your line, further restricting flow.
Water Quality Problems
Another way that galvanized steel piping can affect your home is through water quality issues. That corrosion and sediment in your water will not only change its color but also alter the taste of your water. You’ll notice off-tasting or metallic-tasting water coming out of your tap. It’s pretty common to experience stains on your bathtub, sinks, and even your laundry. You may even notice that the water coming out of certain fixtures appears to be murky or cloudy.
Pressure Problems
If you still have galvanized steel piping in your San Jose home, it’s likely that your water pressure has gotten significantly worse over time. All that internal corrosion, alongside sediment buildup from hard water, can greatly restrict the interior diameter of your pipes. This makes it much harder for water to flow freely through your plumbing system. You may notice weak showers, slow-filling bathtubs or sinks, or even your appliances taking longer to operate.
Identifying Galvanized Steel Piping
If you have galvanized steel piping in your home, then old plumbing replacement is likely the best option. This will restore full water pressure to your home while reducing water quality issues. Whole-home repiping also greatly minimizes your risk of experiencing a major plumbing issue like a pipe burst. If you’re not sure whether or not you have galvanized pipes in your home, there are a few different ways that you can tell.
First, and most importantly, galvanized steel was popular in homes built between the 1920s and the 1960s. If your home was built within this range and you never upgraded your plumbing, you likely have galvanized pipes. If you’re noticing frequent rust-colored water, low water pressure, or discolored fixtures, it’s highly likely you have galvanized piping.
It’s a good idea to inspect the areas of exposed piping in your home. You may find these underneath your fixtures and in your basement or crawl space. Galvanized pipe has a distinct gray to silver tone. They typically have threaded pipe connections, which are much different from the soldered copper or clamped PEX fittings. Galvanized pipes tend to be much heavier compared to modern-day copper or even PVC pipes. It’s highly beneficial to have a professional inspect your home to identify if you do have galvanized pipes and assess their overall condition.
What to Do With Galvanized Piping
If your home has galvanized pipes, there are a few different ways that you can deal with them. The correct approach really depends on the extent of corrosion and your individual budget. A few options include partial repairs, replacement, and complete home repiping. Partial repairs can be great when you have severely corroded sections of galvanized piping that need to be replaced. Plumbers can swap out those sections for modern materials like copper or PEX.
Partial repairs can be helpful when you’re dealing with something like a leak, where you just need to restore your water quality and pressure. However, it’s not a long-term solution to address severely corroded plumbing systems. Rather, that’s where whole-home repiping comes into play. This is where our plumbers will physically remove all your old piping and install new piping from copper, PEX, or PVC, depending on the specific application.
When you upgrade all the piping in your home, it provides you with many different benefits. Most importantly, it ensures a consistent water supply throughout your home and restores proper pressure. It goes a long way in greatly minimizing your risk of experiencing any major plumbing problem in the near future. It’s great not only for giving you peace of mind, but also for increasing the resale value of your home.
Apart from upgrading your plumbing system, it’s important to get routine inspections every year. This will help identify any small issues so that we can repair them before they turn into major malfunctions.
