Can PEX pipes leak?
Significant leaks can occur where PEX piping is used with brass fittings with this kind of sanitation chemical. The chemical interaction produced between the PEX, brass and chloramine salts eats away at the brass with corrosion occurring, small leaks turn into big problems over a short period of time.
Why is PEX tubing used?
Due to the flexible nature of the tubing and ease of connections, PEX tubing reduces the cost of plumbing installation. There are a few issues that users need to be aware of: PEX plumbing tubing is impermeable. This means that oxygen cannot penetrate the tubing, greatly reducing the potential for chemical reactions including corrosion.
What is PEX tubing?
PEX or Cross-Linked Polyethylene tubing has become more widely used over the last few years. It is becoming a strong choice for both remodeling projects and new construction. Due to the flexible nature of the tubing and ease of connections, PEX tubing reduces the cost of plumbing installation. There are a few issues that users need to be aware of: 1 PEX plumbing tubing is impermeable. This means that oxygen cannot penetrate the tubing, greatly reducing the potential for chemical reactions including corrosion. However, the right type of tubing should be used for radiant heating applications. PEX-AL-PEX is recommended. 2 The polyethylene in PEX tubing does not percolate into water. Some chemicals, such as phthalate that filter from plastic, can leak into water systems. This occurs in standing water conditions. Water used in re-circulating heating systems should not be used for drinking water. 3 PEX tubing must be installed correctly. Improper connections will leak and this can become costly. 4 PEX piping is well known for its flexibility and features, but dangers can come from the types of fittings used. The more copper or brass involved, the more risk of corrosion and build up in the system. Lead solder should never be used in making any plumbing connections. 5 Oxygen Barrier PEX pipes must be protected from UV (Ultra Violet) rays of the sun. It is not designed for exposed outdoor use and should not be stored outside for any length of time. UV rays will damage the strength of the material.
Can PEX tubing be used for radiant heating?

Is PEX plumbing safe?
PEX is also not as susceptible to freezing temperatures and resists bursting. By avoiding the issues mentioned, PEX plumbing is very safe for installation.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
Why is PEX C so hard to work with?
Because it’s the stiffest version , PEX-C is the most difficult to work with; this stiffness also makes it most prone to kinking, as well as susceptible to cracking when water freezes. These undesirable traits make PEX-C best suited for short repairs where bending around sharp corners isn’t necessary.
What type of fittings are used for PEX?

Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What type of PEX pipe is used for 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).
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
Can copper leak into water?
My answer is copper. Some people think that copper leaches into their water but that is typical only when there is low pH water. Older copper pipes of course use lead solder and the lead is a problem if it leaches into your water. In any case I prefer copper to the newer pipe options that are cheaper and easier to use.
Does a carbon filter remove toluene?
Carbon filters, such as my Kitchen Defender , at the kitchen sink will remove both toluene and ETBE. The study does not name the other carcinogens, but presumably they are also volatile organics and therefore removable by carbon. What people don’t realize is that carbon filters have a limited amount of toxins they can adsorb before they stop ...
Can pex pipes be carcinogenic?
New pex pipes can leach both toluene and ETBE, volatile organic compounds that are considered carcinogenic. These start at pretty high levels and decrease as the pipe gets older. The information that is new to be is two-fold:
What is PEX pipe?
Cross-Linked Polyethylene (PEX or XLPE) is a flexible plastic (polymer) tubing pipe primarily used in both hot and cold-water distribution plumbing systems. During the past two decades in the United States, PEX has also become a common alternative to copper, polyvinyl chloride (PVC), and chlorinated polyvinyl chloride (CPVC) for use as potable (drinkable) cold and hot water system piping.
Why does PEX piping get damaged?
There have been instances of damaged PEX piping following the attempt to exterminate rodents. Rodent poison typically causes dehydration, and the sound of water moving through the piping has been known to cause rodents to chew through the PEX to access the water.
How long does it take for a PEX pipe to break down?
Most PEX manufacturers allow no more than 60 days of sunlight exposure for normal PEX piping and no more than six months for PEX piping with ultraviolet stabilizers added during manufacturing. Studies have shown a dramatic reduction of chlorine resistance after even one week of direct sun exposure. PEX should not be used in exterior settings or in locations exposed to sunlight.
When was PEX piping invented?

Can PEX be exposed to oxygen?
Exposing PEX to certain petroleum products and oxygen increases the permeability of the piping. In closed-loop systems, such as radiant floor heating systems, oxygen can cause heating element corrosion. If PEX piping is installed underground in soils contaminated by pesticides or petroleum products such as methyl tertiary butyl ether (MTBE), these can permeate through the pipe wall and contaminate the water supply.
Is PEX piping cheaper than PVC?
The installation of PEX piping is typically faster, easier, and less expensive than rigid piping such as copper or PVC. PEX piping is flexible, thereby able to change directions and bend around corners without the need for the elbow fittings required for rigid piping.
