Is PEX safe for drinking water? Yes, our PEX-a and PEX-b are both safe for drinking water. Our piping system solutions are all third-party tested through IAPMO or NSF to the following standards: NSF/ANSI 61 drinking water systems components - health effects.
Pex is very susceptible to UVA damage. Pex is semi permeable, meaning liquids can get inside the tubing and contaminate the water inside . Pex is not antibacterial like copper is. Pex cannot be used in high heat areas like around recessed lights or be directly connected to a water heater.
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won't leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper's intensive extraction and manufacturing process presents some environmental trade-offs.
Bacteria
This mostly happens when PEX pipes are installed deep under the ground and vulnerable to moisture. In extreme cases, the bacteria caused by moisture can penetrate inside the PEX pipes and contaminate the water.
PEX pipes are very thick but they are still susceptible to rodent damage that can cause pipes to crack or break. Possible Leaching: Although uncommon, some homeowners and plumbing companies have reported a few PEX pipes leaching harmful contaminants like BPA (Bisphenol A) into the water supply.
It is well-known that PEX pipes can raise organic carbon levels in water by leaching ingredients, manufacturing byproducts, and other additives.
Currently, PEX plumbing is one of the most widely used plumbing systems around the world. It was temporarily banned in California for a while due to concerns about toxic materials but this was later disproven by laboratory tests.
The problem with PEX seems to be that it's contaminated -- it leaves the factory with chemicals used in its manufacture still on the pipe. In time it cleans up, but during that time those chemicals are going into the water.
On average, PEX pipes can last anywhere from 40 to 50 years, and in some cases, even longer. This impressive durability is due to the material's resistance to corrosion, scaling, and chlorine, as well as its ability to withstand high temperatures and pressures.
Fact: PEX tubing is BPA-free and does not contain other harmful chemicals that could leach into your water supply. Numerous studies, including a comprehensive Norwegian study, have shown that PEX is safe for drinking water and poses no health risks.
Avoid using polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC). These pipes contain the highest levels of chemicals of concern and they are typically installed using hazardous solvents.

Copper pipes:
Copper pipes are prized for their durability and resistance to corrosion. They are also non-toxic and safe for carrying drinking water.
PEX Pipe Class Action Lawsuits
A number of manufacturers, including Uponor, Viega, Nibco and Zurn, have already been sued over their PEX piping products.
PEX pipes are the top option for plumbing in Florida. But that doesn't mean you should automatically pass up a house that uses other materials.
PEX Pipe Is Vulnerable
Rodents Chewing Through PEX Pipe is a common problem in our area. It doesn't matter how old your home is, if you have an attic, you need to watch for rodent damage to PEX Pipe or PVC. If you're hearing rustling noises coming from the attic, it's time to do an inspection.
The answer is yes! PEX piping is approved for use in potable water systems by regulatory agencies like NSF International and meets strict safety standards for drinking water quality. In fact, many homeowners prefer PEX piping for its clean, tasteless water and resistance to bacterial growth.
Lower Lifespan Than Other Materials
While PEX plumbing is cheaper upfront, the cost benefits may be negligible when you consider that it might not last as long as copper or other materials. PEX pipes have an average lifespan of about 40-50 years, while copper can last over 70 years.
Pex tubing is now widely used in water supply projects. Back in history, Pex tubing was created in the 1960s in Europe and was widely used and introduced in the US around 1980.
Defective Manufacturing ISSUES
Some PEX pipe manufacturers use cost-cutting processes which lead to pipes that aren't uniform in composition and are defective. Defective PEX pipes will not last 50+ years as advertised and quickly degrade and become brittle when exposed to hot chlorinated water.
It doesn't corrode, is flexible and easy to install, and can be used with many different connections. But PVC can't handle extreme heat, it melts and could potentially cause negative health impacts. Because of this, using PVC pipes for your drinking water supply is not advised.
PEX pipe is more durable than rigid pipe in cold weather but is still susceptible to burst in extreme conditions.
PEX pipe is safe for drinking water in households and commercial systems. NSF International has teams of toxologists and other technical professionals who administer the NSF 61 standard which requires all components in a water system to be safe for drinking water. This includes PEX pipe systems with drinking water.
Chlorine Degradation Near PEX Fittings
Improper installation is a common cause of leaking in and around PEX fittings, but not the only cause. One issue PEX systems have to contend with is incompatibility with local water conditions.
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.
