Before diving into the pros and cons associated with galvanized steel pipe, you need to understand the basics of this type of pipe. At its essence, galvanized steel pipe is a type of steel pipe that is coated with another metal. An example of the type of metal that galvanizes a steel pipe is zinc.

Steel pipe is galvanized with a substance like zinc primarily to prevent rusting. Galvanizing a steel pipe to prevent rusting renders the pipe itself preferable for use in outdoor projects. Indeed, galvanized steel pipe frequently is preferred for outdoor projects when contrasted with ABS or PVC.
As is the case with any type of product or material, there are pros and cons associated with galvanized steel pipe. When you are considering the type of pipe to utilize for a project, particularly one out of doors, you do need to weigh the pros and cons before making a final decision regarding what course to take.
As was stated at the start of this discussion, steel pipe is galvanized with a substance like zinc in order to prevent rusting. The reality is that in the absence of galvanization, a steel pipe used out of doors and more exposed to the elements would be subjected to the possibility of rusting in relatively short speed.
The galvanization of steel pipe does not make it invincible. Nonetheless, galvanized steel pipe has a relatively long lifespan. You can expect a galvanized steel pipe, used outside, to have a lifespan of about 40 years.
In considering the pros and cons of galvanized steel pipe, cost is certainly going to be a consideration. When analyzing cost-related issues, you need to focus on not only the initial financial investment in a type of pipe, but its lifespan as well.
An alternative to galvanized steel is pipe made from copper. For decades, copper pipe was widely recommended for use in plumbing and related projects. Copper is a good choice, but so is galvanized steel. When analyzing price, galvanized steel is a less expensive alternative. In fairness, copper pipe is likely to have a longer lifespan than galvanized steel. The lifespan of copper pipe generally does run over 50 years. With that noted, this typically is copper pipe used in interior rather than exterior settings, however.
PVC is a popular pipe alternative. One of the reasons PVC is widely used is cost. PVC is less expensive than galvanized steel. While PVC is a less expensive alternative than galvanized steel, its lifespan is far shorter. Thus, in the overall scheme of things, when contrasted with PVC, galvanized steel pipe is a more economical alternative long term.
Galvanized steel pipe is demonstrably preferable for larger construction projects as well as for farm irrigation systems. The two primary reasons why this is the case is because galvanized steel pipe is more durable than many other alternatives. In addition, this type of pipe can be crafted with a larger diameter than is practically possible with some other alternatives.
Some people initially shy away from galvanized steel, despite its benefits, because it can be a bit more difficult to handle. Being made of steel, galvanized steel is heavy when contrasted with lightweight alternatives like PVC. The lightweight nature of PVC, despite some of its other limitations when contrasted with galvanized steel, has made PVC popular among home improvement enthusiasts.
Overall, galvanized steel is generally as easy to maintain as other alternatives, with one possible exception. Galvanized steel pipe is more prone to mineral buildup in the pipe itself than is the case with other alternatives, including PVC or copper. However, with proper proactive maintenance, this type of buildup can be minimized.
One difference between galvanized steel pipe and some other alternatives centers on the response to a damaged pipe. When galvanized pipe is damaged in some manner, it normally is replaced rather than repaired.
Replacement is recommended because damage to a galvanized steel pipe tends to weaken the zinc coating. The weakening of the zinc coating renders the pipe more susceptible to corrosion.
Once you have completed the process of weighing and balancing the pros and cons of galvanized steel pipe, your next step is engaging the services of a professional with experiencing in installing this type of pipe. There are professionals that have extensive experience in the installation and maintenance of galvanized steel pipe in all type of settings.

Our friend Hal owns a house in Sacramento that was built way back before . Hal has been having some problems with low water pressure and discolored water lately, though, and he suspects that this may be due to old galvanized pipes. Hal asks:
&#;I&#;m one of those old-school guys who does everything he can to try to fix a problem with his house himself before seeking out help from residential plumbing experts like yourselves. It&#;s nothing personal, probably just a little bit of foolish pride on my end. Anyway, that&#;s my way of telling you that when the water pressure in my house dropped noticeably lately, and the water started to look a little bit discolored, I did my DIY due diligence.
I took to Internet forums, questioned the guys at the Sacramento Home Depot, and had conversations with my neighbors over the hedges between our yards, all trying to find the source of my problem. I&#;ve dealt with low water pressure in the past, and it&#;s been as simple as just swapping out an old gunky showerhead for a sleek new one. This time is different, though. None of my old tricks have worked and none of my usual sources for home repair information knew exactly what to do. They all just kept wanting to know if I had galvanized pipes, like that would solve all my problems.
So, my question for you now is what are galvanized pipes, could they be causing these problems, and if so, how much does it cost to replace galvanized pipes in a house built before ? My house was built in . Thanks for your help.&#;
As one guy who can be a bit stubborn about asking for help to another, let me tell you, Hal, that I know reaching out for advice wasn&#;t easy, but that it was the right move. Given the age of your house and the conditions you&#;ve described, I think it&#;s pretty likely that you do have galvanized pipes&#;and that replacing them may be the answer to your problem. In general, though, homeowners should expect it to cost anywhere from $1,500 on up to $15,000 (or more) to replace galvanized pipes in their old house. Quite a range, right?
So, for your benefit and for the benefit of other homeowners in Sacramento who likely have the same plumbing situation as you, let me first explain the nature of your issue, before helping you calculate how much it costs to replace galvanized pipes in a house built before .
Hal&#;s instinct to reach out to a plumbing expert here is a good one because updating plumbing in an old house with aging pipes is tricky business. The pipes in a home are one of those things that most folks don&#;t give a second thought to until something goes wrong. Most folks, like Hal, don&#;t even know what their pipes are made of. So, let&#;s start by going over the three most common pipes, as well as the lifespans for each:

Now, the vast majority of the older houses like Hal&#;s in our area have galvanized pipes, which were the defacto choice for residential plumbing dating back to the s all the way on up through the s. It was only recently that it became standard for contractors to build homes with longer lasting brass and copper pipes. And as you can see from the lifespan above, if your home has these pipes, they basically all need to be replaced now.
I&#;ve talked in the past about the most common signs that pipes in a historic home are failing, but let&#;s go over them again because they&#;re pretty much right in line with the problems that Hal described:
If the water pressure when you&#;re taking a shower or washing dishes has dropped significantly, this could be a sign that it&#;s time to replace aging pipes. When galvanized pipes get old, corrosion sets in. Sometimes this also means a buildup of corroded materials in your pipes that inhibits water flow and makes it hard to get the pressure you&#;d like. An experienced plumbing professional can do a video inspection of your pipes to tell you definitively whether or not this is happening.
Galvanized steel pipes are likely to have less protective coating against rust, so they get corroded over time. That&#;s why it&#;s important to watch the color of the water coming from your faucets, like our friend Hal has done. If it becomes milky or reddish in color, it&#;s time to call the plumber.
Hal didn&#;t mention this last one, so he&#;s lucky, but pipes that need to be replaced can lead to leaks in a home&#;s walls and underground. Signs of leaks in these cases might be slow running faucets, slow draining tubs or toilets, and stains on ceilings or walls. These leaks can indicate
piping damage, clogs, or corrosion
. They definitely require the expert care of a licensed plumber&#;especially with the type of wet winters Sacramento and the rest of our region typically has.
Hal, and anyone else who has seen the signs of plumbing troubles listed above, should make it a priority to get their pipes fixed. As a professional plumber for decades, I&#;ve seen it all, so I know this can be costly, but will only get more expensive the longer you wait to address the problem.
Your cost to replace galvanized pipes in your house can vary a great deal based on the size of the house, which is almost always directly proportional to the size of the plumbing system.
The prices we&#;re about to discuss are an estimate. Hal and anyone else in a similar situation should have a trained plumbing professional out for a unique estimate for their individual homes to get exact numbers. As I&#;m sure everyone has noticed around town, it&#;s rare for any two homes built in Sacramento before to be exactly the same, so plumbing replacement costs will vary as well.
&#;homeowners should expect to spend anywhere from $1,500 on the very low end all the way up to $15,000&#;or even more.
As I mentioned above, the size of your home, the number of stories, and the number of bathrooms&#;as well as the amount of existing piping that needs to be demolished&#;will all play a role in the total cost of updating old pipes. The number of fixtures (sink, bathtub, shower, toilets, dishwasher, water heater, etc.) also plays a part, as does the type of pipes you choose to have installed. Copper, for example, has gone up a bit in recent years. In general, though, homeowners should expect to spend anywhere from $1,500 on the very low end all the way up to $15,000&#;or even more. An experienced plumber, though, can help you pick the type of piping that will work for your budget and be a long-lasting choice for your classic home.
The cost to replace old, worn out galvanized pipes is not a glamorous expenditure, to be certain, but it&#;s vital to the long-term health of your home. The damage that even just one leaky pipe in a wall can reap is much more costly&#;and can have an impact on your family&#;s well-being, such as mold growth and weakened structures.
My strong advice is to have a professional plumbing repair company take a look, preferably with a video inspection like the type we&#;ve been doing here at Bell Brothers for many years. Hal was right to know that this sort of job requires an expert. Make sure you pick one that has years of experience doing this kind of work in old Sacramento houses&#;one like the expert a d local team at Bell Brothers.
