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.

Is it worth it to replace copper pipes 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.

What are the disadvantages of PEX?

Will PEX last 100 years?

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.

Why do plumbers use PEX?

PEX tubing minimizes the need for connectors since it's so flexible. Connection sites have the highest potential of leaks in your plumbing system, so fewer PEX fittings leads to less risks of leaks.

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

How long does PEX fittings last?

Generally, PEX pipes last for 25 to 40 years before they need to be replaced. By comparison, copper pipes last for around 50 to 70 years. PVC pipes also last 50 to 80 years. CPVC pipes last 50 to 75 years.

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.

How long will PEX last outside?

According to Comfortcontrolsystems.com, PEX pipes that aren't damaged by external factors should last at least 70 years.

When should you not use PEX pipe?

PEX plumbing is fine inside the walls of a home, no matter the temperatures as it can be covered with insulation. However, one of the disadvantages of PEX plumbing is it cannot be used outdoors in cold climates as there is no way to cover them and protect them from freezing temperatures.

Is PEX safe for drinking water?

There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.

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.

What is the lifespan of copper pipe?

Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years. In most new construction, this is seldom a problem, but if you live in an old home you might want to see what pipe material your house has.

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.

Do copper pipes ever need to be replaced?

There is no known health reason to remove copper pipes in good condition from your home. You should replace any copper pipe that is showing signs of damage or deterioration, regardless of its age. If your water is chronically acidic, copper piping might not be the best choice for your home.

Does PEX become brittle?

Like most other plastics, PEX will become brittle if exposed to sunlight for too long and may crack under pressure. Typical exposure limit is ~30 days.

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.

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 you paint PEX pipe?

Painting PEX Pipe – Experiments

Krylon Fusion sticks to PEX quite well without any preparation, other than a quick wipe with alcohol to remove mold release. So, if you can find a color you like, you can use Krylon Fusion spray paint to turn your orange PEX-AL-PEX into a good looking loop.

Is PEX better for hard water?

While copper, PVC and PEX pipes are more resistant to hard water buildup and corrosion, they can still get clogged or completely blocked by scale deposits.

What causes pinhole leaks in PEX pipe?

Pinhole leaks are unique to copper pipes and are caused when corrosion inside the pipe eats through to the outside, creating a leak.

Which is better PEX A or B?

Bottom line, PEX A is more resistant to burst pressure than PEX B. PEX A's expansive material can handle up to 500 PSI, which makes it reliable in extremely cold temperatures. Since PEX B is a more rigid material, it will not hold up as well in similar situations.

Is PEX quieter than copper?

Water also moves more smoothly through PEX than it does through copper and so is much quieter. Another advantage of PEX is that is doesn't corrode like copper. This is important if you have water that is slightly acidic. In addition, it also resists scale buildup.
