Polyvinyl chloride pipes (PVC) are often used in the toilet, sink, or shower drain lines. Its plastic tubing is ideal for this type of plumbing usage because it protects water from rust and corrosion more effectively than other types of pipes. It's also durable. If it doesn't get damaged, PVC pipes will last forever.
Cast iron will last anywhere from 75-100 years while PVC wins the award for longest-lasting pipe material with an indefinite lifespan.
PVC can last even longer than steel or copper, which are some of the most durable metals for plumbing pipes. Ability to handle pressure: PVC can withstand high water pressure, which makes it an excellent choice for the main supply line in your home.
Brass pipes generally last longer than copper at eighty to one hundred years. This is due to their combined copper and zinc alloy, which results in a tough combination that can last for a century. These pipes are not typically used anymore due to the fact that they contain trace amounts of lead.
METAL PIPES
Ductile Iron Pipe Ductile iron pipes are stronger, more durable, and less brittle. Made entirely out of scrap iron and steel, these pipes have more flexibility and are resistant to shocks and vibrations. They even handle freezing temperatures better than cast-iron pipes.
What is the best piping for plumbing? PVC pipe is by far the most commonly used pipe in residential homes. This type of pipe is affordable and available in a number of different fittings and sizes. It's also a great choice for most warm and cold water applications.
PEX often lasts around 50 years. However, PEX is more durable and has more flexibility than PVC and CPVC. Also, because PEX is made from cross-linked polyethylene, it won't corrode.
How long do galvanized pipes last? No piping system lasts forever, but galvanized pipes have a life span of between 40 to 100 years. If your home's pipes are from the 1960s or earlier, they are likely nearing the end of their functional life span.
CPVC (chlorinated polyvinyl chloride) can last more than 70 years, and PEX (cross-linked polyethylene) can also reach a similar age. Older PVC pipes have shorter lifespans, around 45 years. If your house was built after 1970, you probably won't have serious issues with these plastic pipes.
Polybutylene pipes were banned from new construction projects after 1995, but if they're already in your home, there is no requirement to remove them. This is important to know if you decide to purchase a home that was built between 1978 and 1995.
PVC is most commonly used for drain, waste, and vent lines. It is not recommended for use in potable water lines because it can leach chemicals into the water.
With a life span that's 20 to 30 years longer than PEX pipe, copper is the clear winner. Properly maintained copper pipes can be expected to last 50 to 70 years. PEX pipes that are properly maintained generally last for 25 to 50 years.
Polyvinyl chloride pipes (PVC) are often used in the toilet, sink, or shower drain lines. Its plastic tubing is ideal for this type of plumbing usage because it protects water from rust and corrosion more effectively than other types of pipes. It's also durable. If it doesn't get damaged, PVC pipes will last forever.
Longevity. In the right conditions, PVC pipes can last upwards of 70 years. Both ABS and PEX pipes have about 40-50 years of life.
Is PEX safe for drinking water? Yes, our PEX-a and PEX-b are both safe for drinking water. Our piping system solutions are all third-party tested through IAPMO or NSF to the following standards: NSF/ANSI 61 drinking water systems components - health effects.
PVC pipes can last for 50 to 100 years. This longevity makes them a popular choice for many applications. CPVC pipes also offer similar durability, often exceeding 50 years. Both materials resist corrosion and decay.
Fragility and Brittleness. ASTM F441 CPVC pipes can become brittle over time, particularly under stress or extreme temperatures. This brittleness makes them more prone to cracking and failure. In colder climates, this issue is exacerbated as pipes can freeze and break easily.
PVC and CPVC are more cost-effective than PEX if you price clients by the hour, as they require many fittings secured by clamps cement. PVC and CPVC have more strength and durability than PEX because they are more rigid, making them better suited to outdoor applications where the piping may be subjected to trauma.
Galvanized plumbing was still in use as late as 1990, but its use has since declined due to the corrosion it can cause in the water supply.
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.
Regardless of the material, each of these plumbing products have a life span that you should know so you can gauge whether you need an upgrade. Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 50 years.
Material Concerns: One of the primary concerns about Pex plumbing is the material itself. While Pex pipes are undoubtedly flexible, making them easier to install in tight spaces, they are not as durable as traditional materials like copper or even PVC.
PEX pipes are very thick but they are still susceptible to rodent damage that can cause pipes to crack or break. Possible Leaching: Although uncommon, some homeowners and plumbing companies have reported a few PEX pipes leaching harmful contaminants like BPA (Bisphenol A) into the water supply.
First, check the quality of those pipes, as copper is still the standard for piping and can offer a long-lasting plumbing system if the pipe is well made.
