Better Energy Efficiency – PEX has a lower thermal conductivity rate than copper. As a result, PEX pipes can help keep hot water hotter for longer periods of time. They also produce less condensation on cold water lines, which could lead to fewer moisture-related problems in ceilings and walls.
PEX has been the norm for probably a decade or more. It's cheaper to buy and cheaper to fit than copper and offers virtually no downside.
PEX is an excellent choice. Even though is has a smaller internal diameter than copper, it tends to have similar flow performance and doesn't degrade like metals do.
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.
Absolutely, PEX is becoming increasingly common in new builds and remodels. It's flexible, resistant to scale and chlorine, and generally easier to install compared to traditional copper pipes. Plus, PEX systems can often be more cost-effective, both in terms of material and labor. My credentials?
Like any other material, multiple factors could lead to problems with PEX. Some of these factors could be simple over-chlorination of the water running through it or dezincification, which could weaken and break down the fittings used on the piping. Another issue could be the piping failing to pass a pressure test.
Copper is usually preferred for water supply lines and heating systems but plex is most often used for drain or waste lines because copper corrodes over time. Ultimately, it's up to the homeowner to decide where to spend the construction budget.
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.
Copper Pipes
Copper pipes remain popular among plumbers and homeowners alike because they are corrosion-resistant and best suited to protect the quality of the water. Copper pipes are able to handle high water pressure and are tolerant of both hot and cold water temperatures.
The answer is aluminum.
It has become expensive, can still corrode based on pH levels of water, and in cold climates, frozen water can cause copper pipes to burst.
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.
How Much Does PEX Piping Cost? PEX pipe is more affordable than copper, about $0.50 to $2 per linear square foot, on average. Copper costs $2 to $4 per square foot.
PEX: Due to its flexibility and durability, PEX piping should last at least 50 years. PVC / CPVC: Under typical conditions, these pipes should last up to 100 years. Keep in mind that PVC pipes are often used for drainage because extreme heat can damage them.
Vulnerable to Damage
Plumbing failures can be caused by defective copper pipes several years after installation. Acidic water can be very bad for copper systems. Scale builds up inside the lines and blocks the flow of water through the plumbing system.
PEX, or cross-linked polyethylene, is a flexible plastic material used for water supply piping systems. Originally developed in the 1960s, PEX has steadily grown in popularity due to its durability, ease of installation, and cost-effectiveness.
Cross-linked polyethylene, or PEX, is the new standard when it comes to repiping your house. Since it is made of plastic it is a more cost-effective alternative to copper. Pex is easier to install and lighter in weight, reducing shipping costs too.
Drainage pipes are often made of cast iron or polyvinyl chloride, or PVC. Cast iron will last anywhere from 75-100 years while PVC wins the award for longest-lasting pipe material with an indefinite lifespan.
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.
Currently, PEX plumbing is one of the most widely used plumbing systems around the world. It was temporarily banned in California for a while due to concerns about toxic materials but this was later disproven by laboratory tests.
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.
Copper is more likely to freeze and break.
The challenge arises more frequently in older homes needing more insulation. If you reside in a colder region or have experienced water pipe freezing, opting for PEX when it's time for a repiping endeavor is a wise choice.
PEX plumbing Sensitivity to UV Light
This means it can't be used in applications where it might be exposed to sunlight, a limitation that isn't present with other materials like copper or PVC. This sensitivity can hasten the degradation process, leading your plumbing system to fail prematurely.
If you have high water pressure, PVC pipe is the best option. It's often used for the home's main water supply line for this reason. It's also a lightweight material that's much easier to work with than galvanized steel or copper.
