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.
Water Quality and Safety
However, certain water conditions can lead to corrosion in copper pipes, potentially affecting water taste and quality. On the other hand, PEX pipes do not corrode, ensuring consistent water quality throughout their lifespan.
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.
PEX pipes and copper pipes are both viable options for your water supply line. While PEX pipes are easier to install, cheaper, and more flexible, copper pipes are sturdier and tend to have a longer lifespan.
Copper pipes are pretty terrible. Copper reacts with minerals and chemical additives in the water. After a long time, the copper pipe will wear out. You end up with a leak.
Copper pipes easily outlast PEX pipes by approximately 20 years. You can expect copper pipes to last anywhere between 50 and 70 years, whereas PEX pipes will last between 30 and 50 years.
Copper is Non-Toxic
In the past, pipes were made of lead and other poisonous metals that actually caused a major health crisis in the U.S. Now that lead has been banned, it's a good thing that research has found copper to be a much more suitable material for safe water pipes.
While it is more expensive than pex, your plumbing isn't something you should scrimp on for new construction. Copper is usually preferred for water supply lines and heating systems but plex is most often used for drain or waste lines because copper corrodes over time.
It is well-known that PEX pipes can raise organic carbon levels in water by leaching ingredients, manufacturing byproducts, and other additives.
PVC is most commonly used for drain, waste, and vent lines. It is not recommended for use in potable water lines because it can leach chemicals into the water.
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.
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.
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.
Potential PEX Pipe Problems
Decreased water quality from toxic chemicals and contaminants leaching into your water. Some leached chemicals may encourage bacteria growth in the pipes.
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.
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.
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.
Consumption of high levels of copper can cause nausea, vomiting, diarrhoea, gastric (stomach) complaints and headaches. Long term exposure over many months and years can cause liver damage and death. There are no health concerns affiliated with using PEX pipes.
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.
The Cons of Using Copper Pipes
Installation costs: Copper is more expensive than other piping materials. Since they're also rigid, you must incur the cost of elbow fittings. The rigidity makes them more challenging to cut and fix during installation. The longer it takes to handle the materials, the more cost you incur.
PEX Pipe Class Action Lawsuits
A number of manufacturers, including Uponor, Viega, Nibco and Zurn, have already been sued over their PEX piping products.
It is usually worth it to replace older copper pipes with PEX. PEX is more reliable and durable in the long term.
Vulnerable to Damage
Plumbing failures can be caused by defective copper pipes several years after installation. Acidic water can be very bad for copper systems. Scale builds up inside the lines and blocks the flow of water through the plumbing system.
Copper gradually accumulates in the hair follicle and the outer layers of the hair, where it undergoes oxidative processes that produce free radicals. These free radicals destroy the hair's natural armour (cuticle) and break down the hair protein keratin, thereby also damaging the hair's internal structure.
Their latest report verifies earlier findings that gastrointestinal symptoms such as nausea, abdominal pain, diarrhea, and vomiting occur when copper concentrations reach 4.0–6.0 milligrams per liter (mg/L) [EHP 112:1068–1073].
