How long will PEX last?

Benefits of Copper Pipes

While you can expect PEX to last for 30 to 50 years, copper piping will outdo it by about two decades, with a typical lifespan of 50 to 70 years. Copper is a more durable option that isn't susceptible to rodents or sunlight. These pipes can easily handle water pressure of up to 1,000 psi.

How long is PEX supposed to last?

Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.

What are the disadvantages of PEX?

Does PEX deteriorate?

Generally, PEX does not deteriorate. But, PEX will deteriorate if it's left in the sun. PEX has an expected life of 25 to 40 years. Therefore, it is expected that it will need to be replaced 40 years after it has been installed.

How long will PEX last underground?

PEX has a life expectancy of 40-50 years, made possible by its durable and non-corrosive materials. Burial also reduces sun exposure, which would otherwise degrade the piping. Additionally, PEX tubing materials allow for expansion, making them resistant to freezing/cracking underground.

PEX vs COPPER for Plumbing - Which Should You Use and Why?

Should I replace copper with PEX?

Coupled with low production and shipping costs, the savings resulting from installing PEX instead of copper pipes can be significant. 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.

Which is better PEX or PVC?

When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won't corrode. - Price. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)

Do mice eat PEX?

The Problem

Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home's PEX water pipes, the result can be disastrous.

Does PEX leak over time?

PEX PIPING IS NOT Leak Resistant

It's lack of required fittings and flexible nature allow for quicker installs than traditional rigid pipe systems. This seemingly quick and flexible installation does have its downfalls.

What is the problem with PEX plumbing?

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.

How long does PEX last vs copper?

Although copper piping takes significantly longer to install, it does provide a longer overall lifespan. Copper manufacturers typically offer a 50 year warranty in comparison to 25 years for PEX, but this of course may vary by supplier.

Will PEX freeze and burst?

If the weather gets cold enough, PEX pipes can and will freeze – – like any plumbing. However, PEX may be less likely to rupture as a result of freezing. However – manufacturers won't provide a guarantee against rupture due to freezing.

How reliable is PEX plumbing?

ASTM International, a standards organization, requires that the life expectancy for PEX pipe be at least 50 years. (Some PEX manufacturers offer a pipe life expectancy of more than 100 years.) In short, PEX is more durable and provides longer system longevity with less time and material invested in the installation.

What causes PEX pipe to leak?

When water leaks from a PEX connection, it is generally caused by one of the following: 1. DeZincification – occurs with certain water chemistry, causing selective leaching of zinc from brass alloy and resulting in weakening of the fitting and leakages.

How do I stop mice chewing my PEX?

Make sure to seal up any spaces around window or wall-mounted air conditioners. Provide a water source. It may seem like you're encouraging the problem but setting out a bowl of water will keep rodents from chewing on water lines to hydrate allowing you time to do preventive maintenance.

Can PEX be used underground?

In slab and underground

Some plumbing contractors may be surprised to know that PEX is approved for use in underground as well as in-slab applications. For jurisdictions that allow PEX in these types of applications, this can be a big advantage.

Can PEX pipe be used for hot water?

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

What pipe is best for plumbing?

Strengths: Copper is unquestionably the premium choice, simply because it has such a long and proven history. Copper piping has been used for 80 years -- and many of those original lines are still going strong. Enviro factor: Copper plumbing pipe won't pollute your drinking water, and old pipes can be recycled.

What is the best pipe to use for underground water line?

HDPE (High Density Polyethylene) pipes are a considered the best choice for underground water lines. What makes this type of piping so great? HDPE pipes are non-toxic, tasteless, and considered a green building material. The pipes are designed to be high crack- and corrosion-resistant.

Is PEX water line better than copper?

Copper lasts longer than PVC pipes.

It's tough to beat copper pipes for longevity, which on average last 50 to 70 years, compared to PEX, which has an expected lifespan of 30 to 50 years.

Which type of PEX is best?

PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.

Is PEX cheaper than copper?

The price of PEX pipes itself are cheaper than copper pipes. If you hire a professional, the labor cost will also be lower given how quick and easy it is to install PEX pipes. Rodents can eat through them. Since PEX pipes aren't as hard as metal, it's possible for rodents to chew through your PEX pipes.

Which is better PEX expansion or crimp?

PEX crimp equipment is a lot more affordable than the expansion kits. However, despite the pricing and form shortcomings, most plumbers prefer to work with expansion because installation is more efficient. There are fewer leaks, and it also seems to be more durable against extreme colds and frozen pipes, etc.
