Does sunlight hurt PEX pipe?

In piping constructed of PEX, UV light exposure is more of a concern. UV light acts as a strong catalyst for the oxidation process within these materials. When PEX piping is exposed to UV light, it consumes the chlorine-inhibiting anti-oxidants which protect the pipe from chlorine induced oxidation.

Can PEX be in direct sunlight?

PEX pipe is not approved for outdoor applications and is not approved for continuous UV exposure. PEX pipe should not be stored in direct sunlight.

Can PEX be exposed outside?

A: The PEX material can be used outdoors if it is buried or otherwise protected. PEX piping can deteriorate in the presence of ultraviolet rays, so it should not be used outdoors if it will be exposed to sunlight.

How long does PEX last outside?

Most manufacturers put UV stabilizers in PEX tubing to provide at least 30 to 60 days UV protection.

Is PEX water pipe UV resistant?

Key differentiators regarding PEX quality are chlorine resistance and UV resistance. All SharkBite PEX that is marked with Material Designation code “PEX 5306” indicates continuous recirculation listing and six-month UV protection. PEX 5306 rating also makes SharkBite PEX the highest-rated in the industry.

When PEX goes horribly wrong

How do you protect PEX pipes?

Use suspension clips to protect PEX pipes from friction damage. Like other pipes, PEX tubing expands and contracts in response to temperature changes. Over time, these small movements can wear away the outer surface of the pipe and create leaks.

Can PVC pipe be exposed to sunlight?

PVC does surprisingly well when exposed to ultra violet rays (sunlight). Research shows little to no effect on PVC's tensile strength or elasticity after prolonged sun exposure. The only degradation that seems to occur is impact strength.

Does PEX get brittle over time?

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.

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.

What are the disadvantages of PEX?

PEX Plumbing Disadvantages

• PEX may leach BPA and other toxic chemicals. ...
• PEX is extremely sensitive to UV light. ...
• PEX can be damaged by chemicals and pests. ...
• PEX can't be installed in high heat areas. ...
• PEX is semi-permeable, which means liquid can enter the pipe.

Can PEX be used outside above ground?

PEX is not suitable for outdoor use. Ultraviolet rays cause PEX to break down quickly—tubing left outdoors can harden and crack within a couple of months.

Can you run PEX in exterior walls?

As a general rule of thumb, if your PEX piping is traveling through interior walls or insulated exterior walls, you don't need to insulate it. However, piping exposed outside or inside unconditioned spaces like a basement, crawl space, or attic should be insulated, mainly if you live in cold-weather areas.

What is wrong 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.

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.

How long is PEX exposed to sunlight?

PEX piping that is indoors is also susceptible to this oxidation. One study found that UV exposure from fluorescent lights for eight hours is equivalent to one minute of sun exposure. According to at least one PEX manufacturer's installation instructions, contractors are advised “Do not install … within 5 ft.

How many years will PEX last?

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.

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.

How long can PVC pipe sit in the sun?

As a general rule, PVC pipe will last 50 to 80 years in the sun. Interestingly, the sun does not affect PVC negatively in any way. The lifespan of PVC pipes is estimated at 50 to 80 years. So PVC pipe will last a long time in the sun.

How do I protect my PVC pipe from the sun?

For permanent above-ground PVC pipe installations, it is recommended that the pipe be protected from sunlight exposure. This can be accomplished by wrapping the pipe with an opaque material, or more commonly, by painting it. If the pipe is to be painted, a water-based paint formulated for exterior use is recommended.

Which pipe is best for outdoor use?

Polyethylene pipes are used in a wide range of pipes for drainage, irrigation, water service and even some varieties for underground gas transport. It is durable and provides long-term resistance to environmental conditions in outdoor and underground uses.

What temperature can PEX withstand?

But be aware that the general rule of thumb is that pex tubing can withstand temperatures of up to 200 degrees Fahrenheit.

Do PEX lines sweat?

Does PEX Pipe Sweat? Any pipe, including PEX pipe, will condense, or sweat, when the water inside is cold and the air outside is humid and hot. This happens for the same reason that a glass of cold water or other beverage attracts condensation when outside on a hot day.

Does PEX piping need to be insulated?

Does PEX Pipe Need To Be Insulated? Yes, although PEX pipes can withstand freezing temperatures better than other pipe materials - but they are not freeze proof!

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.
