There are many types of plumbing pipes available for homeowners today. Whether you’re replacing old pipes or working on a new build, it’s essential to know your options. Different pipes work better for different jobs, so let’s explore what’s available and find the best choices for your plumbing needs.
PEX Piping
Polyethylene (PEX) piping is a type of plastic used for water supply systems in homes and businesses. One of its biggest advantages is flexibility, which makes it easier to install compared to more rigid pipes. PEX is also very heat resistant and durable.
While the initial installation cost for PEX can be higher than other materials, it requires little to no maintenance afterward. PEX pipes come in various sizes, from ¼ inch to 4 inches in diameter, but the most commonly used sizes for water supply are ½, ¾, and 1 inch.
Other important benefits/characteristics of PEX piping:
- Generally leak-free
- Easy to install
- Helps save energy by reducing heat loss
- Resistant to corrosion
- Less likely to build up scale than other pipes
- More affordable than copper pipes
- No need for soldered or threaded connections
- Great option for small businesses and homes
Copper Piping
Copper pipes are a strong and reliable choice for building or updating gas line plumbing systems in homes and businesses. They can handle high pressure (up to 1000 psi) and work well with both hot and cold temperatures. Although copper pipes cost more than other types, they can last a long time—up to 50 to 70 years with proper installation. However, keep in mind that they may not perform as well if your water is very acidic.
Other important benefits/characteristics of copper piping:
- Most widely available material
- Resistant to corrosion
- Fire-resistant
- Suitable for both hot and cold water
- Requires soldering by a professional
- Does not release harmful materials like lead into water
- Fire-resistant
PVC Piping
Polyvinyl chloride (PVC) pipes are used for many purposes, including transporting drinking water and in fire sprinkler systems. They are a strong and affordable alternative to old lead pipes, making them popular in the U.S. and Europe. PVC pipes can last for over 100 years.
Other important benefits/characteristics of PVC piping:
Used for drinking water and sewage applications
Available in various thicknesses for different jobs
PVC pipes for drinking water are specially designed to meet health standards
Made from low-carbon, recyclable plastic, making it an eco-friendly choice
Galvanized Piping
Galvanized pipes are made of steel coated in a protective layer of zinc to help prevent rust and corrosion. They were popular after World War I and up until the 1960s as an alternative to lead pipes, and some homes even used them into the 1980s. However, after years of use, galvanized pipes can develop rust and corrosion, which can cause serious issues in your plumbing system.
Other important benefits/characteristics of galvanized piping:
- Cheaper and more durable than copper pipes
- Wider diameter allows for better water flow
- Rust may become visible in the water over time
- Mainly used for gray water (excess water from baths, sinks, and appliances)
