The lifespan for the most common residential plumbing systems are: Brass: 40 to 70 years. Copper: 50 or more years. Galvanized steel: 20 to 50 years.
Supply Pipes
Brass pipes have a general life expectancy of around 40-70 years while copper usually only lasts around 50 years and galvanized steel taking the prize for the shortest lifespan of around 20-50 years on average.
The average lifespan for common piping materials may vary as follows: Brass (40-70 years) Galvanized steel (20-50 years) Cast-iron pipes (75-100 years)
Take a look at your pipes. If you notice discoloration, particularly around a joint, that indicates moisture and could mean you have a leak. There's a bad smell. Your plumbing involves a system of traps, drains, and vents designed to keep sewer gas out of your house.

Signs of pipe corrosion occur as early as two years post-installation. A neutral or acidic pH of water dissolves the copper oxide barrier of pipes, making them vulnerable to accelerated corrosion, resulting in pinhole leaks.
If your old plumbing pipes are leaking or have visible signs of wear and tear such as cracks or holes in them, then they may need to be replaced entirely. Replacing leaking pipes requires cutting out the damaged section of pipe and replacing it with new piping materials like PVC or PEX.
If you see signs of flaking, discoloration, and dimpling on exposed pipes (such as those in the basement or crawlspaces), have a professional plumber in as soon as possible. The plumber can determine if you need pipe replacements and how extensive.
Smaller homes can take as little as two days, while larger homes may take a whole week. Repiping doesn't mean you'll be without plumbing the entire time. The only time you won't have access to water is when the plumbers are replacing the old system with the new system.
Pipe Corrosion: Assess the condition of your pipes by looking for corrosion damage and signs of rust. If either of these are clearly noticeable, then it is time to repipe your house.
Replacing old pipes with copper piping costs, on average, between $4 and $12 per linear foot or $4,000 and $12,000 for 1,000 linear feet of pipe and doesn't include removal of the existing supply lines.
A full repiping of your home is a big investment and renovation. You will need to bring in a plumber to inspect your old system and provide an estimate for the work. You should consider multiple estimates from local plumbers to see which offer is the best.
You can expect copper pipes to last anywhere between 50 and 70 years, whereas PEX pipes will last between 30 and 50 years. While 70 years is a long time, 20-50 years is more than enough for those living in a starter home or looking to sell after their kids are grown and off living their lives and retirement has set in.
In most cases, PEX is extremely durable and lasts up to 50 years or more. PEX piping is also less likely to crack or break than metal pipe because it does not expand and contract as much when heated and cooled.
Common Types of Copper Piping and Their Average Lifespans:
M-type piping is the thinnest residential copper piping variety, and typically lasts for 20-50 years. L-type copper pipes are of medium thickness and can last for 50-100 years. As the thickest variety of copper piping, K-type pipes can last for over 100 years.
To repipe your home, the plumber will need to cut holes in the drywall to access the pipes and construct the new system. It's important that you cover your furniture and décor to protect it from damage during the renovation. It's important to consider the time frame for your water shutoff.
If your pipes are made if a dangerous material, replace them. Lead pipes are extremely dangerous to your health, and polybutylene pipes are likely to rupture. If you have either of these types of pipes in your home, replace them as soon as possible. How do you know the composition of your pipes?
Old materials, weakening soldering, or even a tree root breaking through the pipe can also bring bacteria or mold into your home. Again, when these things are in under-used sections of plumbing, they grow and spread. Eventually, this bacteria and mold growth can make its way into your drinking water or your home.
Copper pipes that are green and corroded-looking may not necessarily need to be changed; they just look that way. Yet copper pipes do go bad eventually. Original copper pipes may be nearing the end of their useful lifespan and it's not always easy to recognize when they need replacement.
Though rusty water may look and taste unpleasant, it is not generally a health concern. Iron in water is not a sign of harmful bacteria or lead, which are hazards. The limits set by the Environmental Protection Agency (EPA) for iron in drinking water are based on aesthetics (taste, odor, color), not safety concerns.
Add Protection to All Metals
Protective linings or special coatings can prevent corrosion in pipes as well as other surfaces. That includes things such as beams, joints, and bolts. For instance, galvanization works by adding a layer of zinc to metallic surfaces such as steel or iron.
With the exception of a condition called hemochromatosis, people who drink rust in water won't suffer ill health effects. Rust is oxidized iron, which isn't harmful. But this doesn't mean you should tolerate having rust in your home's water.
Thanks to advances made in the industry, PVC piping has evolved to become incredibly durable and can last up to 70 years or more. Unlike other piping, PVC pipes don't corrode and never let any metal spill into your water, keeping it clean and safe.
