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.
Hep2o (polybutylene) and PEX (polyethylene) are both suitable for potable water.
One easy way to tell ABS and PVC apart is that ABS pipes are black and PVC pipes are white. But since pipes aren't meant to be seen, plumbers are usually more interested in other qualities. For example, PVC is more flexible, but ABS is stronger and more shock resistant.
If you are finding particles in the water, or have the taste mentioned above, you could have black alkathene. Black Alkathene pipework was often used as the supply pipe to properties in the 1960, 70s and 80s.
Polyethylene Fusion Pipe - Black HDPE Polyethylene Pipe - Hdpe Supply.
Black poly pipe (polyethylene or PE pipe) is used in many facets of home plumbing, both for drinking water lines and other applications inside a residential house. This type of pipe is available in very long rolls for the water main between the meter and the house and for sprinkler systems.
Is Poly-B the same as PEX? No, they are actually very different types of piping. To discuss, poly-b is a type of plastic piping made from polybutylene, while PEX (cross-linked polyethylene) is a newer and more durable option that has been gaining in popularity over the past few years.
PEX Pipe. PEX, a cross-linked polyethylene pipe, is considered by some to be the greatest innovation for DIY plumbers. PEX pipes often replace copper for hot and cold water in residential retrofits. They are easy to cut, install and connect and less costly than copper.
PEX-a pipes are very resistant to corrosive chemical agents. They have an excellent thermal memory, smooth and are lightweight and flexible. Its outer coating, or last layer, is made of 3% carbon black, which gives it its characteristic black colour and makes it resistant to ultraviolet rays.
The culprit is polybutylene (PB) pipes, which were used for plumbing purposes between the years of 1975 and 1978 until it was discovered that they become brittle and cracked over time, so they were subsequently outlawed.
Commonly referred to as “pond hose”, “flex tubing” and “flex PVC”, our black flexible PVC hose is strong and long-lasting, as well as extremely flexible. The black color prevents sunlight penetration which reduces the ability for algae to grow, and makes it practically invisible underwater.
PEX is made of cross-linked HDPE (high density polyethylene). To make PEX, the molecular structure of polyethylene material is chemically or physically modified so its polymer chains are permanently linked, forming a high-performing pipe suitable for a variety of potable and non-potable plumbing applications.
Black Unplasticised Polyvinyl Chloride (uPVC) Sheet is a durable and versatile material, offering excellent chemical resistance, rigidity, and mechanical strength. With a sleek black finish and Class 1 fire rating, this sheet is suitable for industrial, chemical, and ventilation applications.
Although no regulations require the replacement of polybutylene piping with other material, many plumbers recommend doing this, at a cost several thousand dollars. Leaking can happen without warning and can result in flooding and serious damage to a home's interior if it is not immediately stopped.
The cost to replace polybutylene pipes runs between $300 and $5,100, with the average homeowner spending $1,200 on polybutylene pipe replacement. Polybutylene pipes are no longer used in new construction because they are prone to defects, leaks, and pipe bursts.
Overall, polybutylene pipes should not completely deter you from purchasing a home you love. You should, however, take some additional steps if you do decide to make a deal on a house with these types of pipes. Hiring a professional plumber is key to ensuring the pipes are still in good shape.
ABS, or acrylonitrile butadiene styrene, is a black plastic pipe that is commonly used for drainage, sewage, and vents.
Caution: Do not use Uponor AquaPEX piping to connect the tub and shower valve to the tub downspout as this may create excessive back pressure in the valve, causing it to remain slightly open. I have always known pex to outflow copper...

PEX has a high tensile strength and is highly durable, cost-effective, and flexible. Yet, it can still experience the concern of pipe cracks or general damage when under the influence of things like significantly intense UV rays.
It is recommended that if a home has polybutylene pipes, the entire plumbing system should be replaced immediately, as a costly leak can happen at any time, without warning, and cause large-scale damage.
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.
Looking at the marking is one of the easiest ways to identify PEX pipes since most manufacturers label them for this purpose. Usually, there are markings/printing on the exterior of PEX tubing that clearly says “PEX A” or “PEX B,” indicating the type of PEX tubing you have.
Interior polybutylene pipes are most often gray, but they can be black. If they are outside the home, they may even be blue. The pipes are usually a half-inch to 1 inch in diameter. Polybutylene pipes are flexible and will bend easily with just a little pressure.
