Why do plastic pipes have seals?
In some cases, plastic pipes will also have a laboratory seal to signal that they can be used for potable water. This makes it easy to identify the type and purpose of the pipe so you can replace it, if necessary.
What is ABS pipe?
ABS: Short for acrylonitrile butadiene styrene, this sturdy plastic was one of the first plastics used for residential plumbing. ABS pipes are always black and tend to be softer than PVC. They are mainly used for vent and drain lines, along with other outdoor underground uses where cold temperatures are common.
Why is plastic piping low heat conductivity?
At the same time, their low conductivity helps maintain the temperature of the water inside without creating condensation like copper pipes are prone to do (if not insulated).

What type of plastic is used for plumbing?
There’s no single type of plastic used to manufacture pipes. For years, a gray plastic called polybutylene was common for plumbing systems, but it’s no longer used because it splits and creates leaks. If you have old polybutylene pipes in your house, we strongly recommend you arrange to have it replaced with a newer type of plastic pipe. Here are the three types of plastic water pipes that are commonly used by plumbers today:
What is the most common pipe material used in plumbing?
Indoor plumbing has been around for a long time, and the materials used for the pipes have gone through many changes. For decades, metal and ceramic were the most common pipe materials.

This type of plastic water pipe will not corrode and features a low heat conductivity.
Is PVC pipe better than PVC?
This is PVC piping that’s gone through chlorination (treatment with chlorine). CPVC is more durable at higher temperatures and pressures than PVC and is common in industrial plumbing. For homes, it’s great for carrying drinking water and handling the hot water lines for which PVC is unsuited. CPVC is more flexible as well. However, it cracks if it freezes, so CPVC isn’t useful for water mains because those pipes must be buried in the ground.

Two additional types of pipe are sometimes found in older homes and are infrequently installed, especially by DIYers: steel and cast iron pipe. Galvanized steel pipe was used for decades for drainage, water supply, gas supply, and any number of other purposes.
What is PEX pipe?
PEX is a pipe that is rigid enough to withstand the pressures of water supply but flexible enough to weave throughout walls, ceilings, basements, and crawlspaces. PEX has truly delivered water-supply plumbing into the hands of do-it-yourselfers and professional plumbers.
Why is copper pipe good for water?
Rigid copper pipe is great for water supply because it does not come with any health risks. 1 . Among the multiple options for connections, the best is the solder-type connection. The solder connection requires experience coupled with safety protocols.
Is cast iron pipe still used?
Cast iron pipe was often used for sewer and other drainage purposes. Cast iron pipe is still found in many homes. Cast iron pipe is viable until the point that it rusts completely through. Cast iron is very heavy and difficult to cut. Retrofits tend to replace cast iron pipe with rigid plastic pipes such as ABS.
Is galvanized steel pipe used for water?
While galvanized steel pipe is still around (particularly for gas supply) it is far less used and is never used for water supply in new construction or remodel projects. Each end of the pipe is threaded, and individual pipes are screwed into each other with connecting fittings. Cast iron pipe was often used for sewer and other drainage purposes.

Is chlorinated PVC safe to use?
Just like unplasticized PVC pipes, chlorinated PVC pipes are highly resistant to corrosion and safe to use for drinking water. Also, both are durable due to their great impact resistance. The biggest difference is that chlorinated PVC pipes are resistant to a wide range of temperatures.
1. PVC pipe
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.
2. PEX pipe
PEX, or cross-linked polyethylene, plastic piping comes in three types: A, B, and C. A is the most flexible, B is slightly less flexible, and C is the stiffest, suitable for quick repairs. Not all varieties of PEX pipe are available in all areas.
3. ABS pipe
ABS, or acrylonitrile butadiene styrene, is a black plastic pipe mainly used for drain, waste, and vent piping. ABS pipe can be used both indoors and outdoors, is lightweight, and is joined by using a one-step cement.
4. Copper pipe
Copper pipe is the most widely used hard pipe for water supply in residential and commercial applications. There are rigid copper pipes and flexible varieties as well. It comes in three wall thicknesses: M, L, and K. Connections are made by soldering flux onto the joint where the pipe and fitting or connection meet.
5. CPVC pipe
CPVC, or chlorinated polyvinyl chloride, plastic is similar to PVC pipe and has similar uses. The added chlorine makes the plastic harder and more durable than PVC. CPVC can withstand hot fluids up to 200 degrees Fahrenheit but is more expensive than PVC.
6. Galvanized steel pipe
Galvanized steel piping was originally introduced as an alternative to lead pipe. It was generally used for drain, waste, and vent piping before the 1980s. Now, galvanized steel is common in gas piping. Galvanized pipe has threaded connections that make it easy to connect.
7. Cast-iron pipe
Cast-iron pipe is not frequently used today in residential plumbing, though some older homes may have cast-iron piping. Cast-iron pipe is typically used for commercial or civic piping and water distribution, as well as sewer and drain lines.
What is copper pipe used for?
balticboy / Getty Images. Copper pipe is mostly used for hot and cold water distribution, as well as being regularly used in HVAC systems for refrigerant lines. Although once used in gas piping, this is no longer allowed in most jurisdictions.
What is CPVC pipe?
The acronym CPVC stands for chlorinated polyvinyl chloride. It is often (but not always) a cream-colored or off-white plastic. This type of pipe can stand temperatures up to about 180 degrees Fahrenheit or so (this depends on the schedule), so it can be used for both hot and cold water lines. CPVC is the same outside diameter as copper and PEX, so the same push-fit fittings used for PEX and copper, such as SharkBite, will also fit the CPVC piping.
What is PVC used for?
Historically, PVC was one of the first forms of plastic used instead of copper for water supply pipes. PVC is normally used for cold water pipes only, as heat can eventually break down the plastic. Always check with local code restrictions before using PVC pipes for hot water delivery lines. In homes plumbed with first-generation plastics, the cold water lines are often PVC, with CPVC used for hot water lines.
How long does copper water pipe last?
For many years, copper was the gold-standard for water supply pipes, as galvanized steel fell from favor. Copper plumbing pipes can last for up to 50 years, but as it ages, copper thins out, eventually leading to pinhole leaks. More recently, various forms of plastic have replaced copper as the favorite, though copper pipes and fittings are still widely available. Due to the price of copper and longer labor needed to install, many builders have switched to alternative water distribution piping, especially PEX.
How long does a PVC pipe last?
According to the International Association of Certified Home Inspectors (InterNACHI), CPVC and PVC pipes generally last for 50 to 80 years under perfect conditions, though early failure is also reported in some circumstances. 2
What is cold water line?
In homes plumbed with first-generation plastics, the cold water lines are often PVC, with CPVC used for hot water lines. PVC connections are made by using a primer that softens the PVC and then applying PVC glue that melts the joints and pipe together.
What is galvanized pipe?
Galvanized pipe is steel pipe that has been treated with a zinc coating. This galvanized coating keeps the water from corroding the pipe. It was once the most common type of pipe for water supply lines, but because labor and time that goes into cutting, threading, and installing galvanized pipe, it no longer used much, except for limited use in repairs. However, galvanized pipe for water distribution is still seen in larger commercial applications.
