Polyvinyl Chloride (PVC) Pipe PVC pipes are widely used in new water main connections. However, PVC is one of the oldest synthetic material in use for many other applications. PVC is thermoplastic and can be softened and molded. This means that PVC pipes are ideal for trenchless construction and installation.
PVC pipes, on the other hand, are primarily used for water main lines. This is because PVC is known for its corrosion and chemical resistance, in addition to the fact that it's lightweight, relatively cheap, and long lasting.
CPVC pipe can withstand higher temperatures than PVC or PEX pipe (up to 200 degrees Fahrenheit vs. 140 degrees Fahrenheit). It's ideal for residential water distribution because it offers better joint strength than PVC and copper and better corrosion resistance versus metal pipes.
PEX is often the better choice for residential plumbing due to its flexibility, durability, and resistance to freezing, reducing the need for fittings and minimizing leak risks. Its ease of installation and long-term reliability generally make it a more practical option over CPVC for most homes.
PVC, or polyvinyl chloride, plastic is a common type of pipe in residential and commercial buildings. PVC pipes are versatile and can be used indoors, outdoors, and underground. PVC pipe can provide water supply to buildings or fixtures or be used for drain and vent piping.
Galvanised steel or iron pipes:
Galvanised steel or iron pipes are used for drinking water in many homes and buildings. The pipes are usually made of a steel or iron core, which is then coated with a layer of zinc. This protects the pipe from corrosion, making it an ideal material for carrying potable water.
Yes, PEX pipes can be buried underground. However, it's important to follow local building codes and guidelines to ensure compliance and the longevity of your plumbing system. To ensure optimal performance and protection against external factors, it is essential to bury insulated PEX pipe at the appropriate depth.
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.
PEX-A is the most flexible and is suitable for use in all home water-supply plumbing needs. It is the most resistant to cracking due to freezing, as it can expand the most.
PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.
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.
Using PVC plastic for plumbing and pipes
It can be used with many different fittings and sizes. Typically, PVC pipes are used for sink, toilet, and bathtub drain lines, as well as for main water supply lines, irrigation piping, and vent stacks.
PVC is only intended for cold water and has a maximum service temperature of 140° F for pressure applications. Not only can CPVC handle higher temperatures than PVC, but its increased temperature resistance enables it to perform better within PVC's working range.
PVC has a peak temperature threshold of 140° Fahrenheit. For applications requiring temperatures above that, CPVC (chlorinated polyvinyl chloride) is recommended. CPVC offers some benefits over PVC, but at a slightly higher price point.
Avoid using polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC). These pipes contain the highest levels of chemicals of concern and they are typically installed using hazardous solvents.
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 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.
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.
Cost aside, the best long-term solution is to re-pipe your entire home, replacing copper pipes with PEX. This involves disconnecting and bypassing all your existing copper and running new PEX lines throughout the house. You can either follow the current pattern or start anew with a PEX manifold-and-branch system.
Polyvinyl Chloride (PVC) Pipe PVC pipes are widely used in new water main connections. However, PVC is one of the oldest synthetic material in use for many other applications. PVC is thermoplastic and can be softened and molded. This means that PVC pipes are ideal for trenchless construction and installation.
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.
Containing an average lifespan of 50-70 years or more, copper piping is an excellent long-term investment . Typically lasting 25-40 years, PVC pipes have a good lifespan. However, they may be susceptible to damage from exposure to extreme temperatures and certain chemicals.
PEX pipe is not approved for outdoor applications and is not approved for continuous UV exposure. PEX pipe should not be stored in direct sunlight.
PVC. Polyvinyl chloride (PVC) is one of the most common types of piping, and it can be used for underground water supply in some applications. PVC is generally inexpensive and is a reliable, durable material. It is rigid, resists corrosion, and can have a lifespan of over 100 years.
PEX Pipe Class Action Lawsuits
A number of manufacturers, including Uponor, Viega, Nibco and Zurn, have already been sued over their PEX piping products.
