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 is PEX plumbing bad?
PEX plumbing system has been used for more years and therefore its failures has been observed and known. Its major failures is linked to piping and fitting. Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation.
Is PEX plumbing reliable?
The reasons are obvious – PEX has flex; it is inexpensive; and the installation is fast, simple and reliable. Also, PEX will not burst in freezing conditions like CPVC or copper. PEX installations older than 30 years are common in Europe, with an excellent reliability record.
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.
Does PEX deteriorate?
Defective PEX pipes will not last 50+ years as advertised and quickly degrade and become brittle when exposed to hot chlorinated water. We also offer remediation consulting to help determine the most cost effective way to restore the piping system to a reliable condition.
Why is PEX banned in California?
PEX was banned in California due to some concerns about toxic materials leaking through the pipe and into water. Through various national laboratory tests, PEX has proven to be completely safe and durable. It is now legal in California and even included in principal plumbing codes.

Should I use PEX A or PEX B?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
Should I replace copper with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
Can I use blue PEX for hot water?

Can rats chew through PEX pipe?
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 need to be insulated?
PEX is treated the same as copper, iron, PVC or CPVC for the same end use. PEX tubing does not provide any significant thermal insulation properties and would not meet code requirements without additional insulation.
Where is PEX not allowed?
Pex not being allowed in commercial or industrial buildings, and thus not in residential buildings deemed “commercial industrial”.
Is there a recall on PEX plumbing?
On October 26th, 2018, the NIBCO PEX Settlement Administrator and Plaintiffs’ law firms announced a class action settlement involving allegedly defective PEX tubing, fittings and clamps.

Which PEX is best for drinking water?
Most plumbing applications, especially those involving potable water, call for the use of non-oxygen barrier PEX, offered in several grades. PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures.
What is better copper or PEX?
Copper Pipe Lifespan. PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. PEX pipe is more resistant to bursting in freezing conditions than metal piping.
Is PEX better than PVC?
PEX pipe is better to use as an electrical and radiant heat insulator in extreme conditions because it resists both better than PVC and CPVC, though PVC is used in combination with a plasticization process to insulate wires.
Should I use PEX?
We generally belive that Plumbing PEX Tubing is much better than Copper for most, if not all, plumbing systems. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. PEX Tubing is cheaper because it takes much less labor to install. PEX Tubing is quickly becoming the industry standard.
