Pex vs copper new construction

Is PEX as good as copper?

PEX doesn’t degrade like copper , higher PSI rating freezing pipes will still burst, but PEX will be able to handle more freezing water than copper . 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.

Why is PEX banned in California?

It was banned by California’s Building Standards Commission because there was a concern that some chemicals may leak from the pipe into the water. So, the authorities of California banned the PEX thinking that it may cause unnecessary exposure to chemicals or carcinogens which may lead to dangerous effects.

Is PEX safe for drinking water 2020?

Researchers have found 158 compounds in drinking water associated with plastic pipes, and a recent study on PEX discovered highly variable impacts on tap water quality, taste, and smell. Testing your water for plastic chemicals that may be leaching into your water is the best way you can protect yourself.

Do new homes use copper pipes?

Plastic pipes are common in today’s new construction of homes , but many homes have copper pipes , too.

Why is PEX plumbing bad?

PEX failures Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.

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.

Should I insulate PEX pipe?

The protection needed to prevent PEX pipes freezing is the same as for all other piping materials. If that’s not possible, then the pipe needs to be insulated — and in some cases wrapped with heat tape and then insulated.

Which is better PEX A or B?

Flexibility – PEX -A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX – B pipe. Kink-Resistance – PEX -A has the greatest resistance, PEX – B the lowest.

Is PEX pipe banned in California?

Unfortunately for Californians, Pex is currently banned by the state. Despite frequent requests for approval, Pex continues to be denied and cannot get added to the list of approved materials when it comes to residential construction projects. Is Drinking Water from Plastic Piping Harmful?

What is the safest pipe for drinking water?

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.

How long does PEX pipe last?

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.

Where is PEX not allowed?

Pex not being allowed in commercial or industrial buildings, and thus not in residential buildings deemed “commercial industrial”.

Why is copper plumbing bad?

Copper does have a few disadvantages, though. It has become expensive, can still corrode based on pH levels of water, and in cold climates, frozen water can cause copper pipes to burst. PEX installs quickly, which significantly reduces labor costs.

When did they stop using copper pipes in houses?

Copper was the plumbing pipe of choice from the 1950s until 2000 and was widely used both in new construction and to replace the galvanized steel water supply pipes that had been the standard into the 1950s . But copper’s use has gradually faded over the last 20 years, due to the introduction of PEX plumbing tubing.

Is PEX quieter than copper?

Water also moves more smoothly through PEX than it does through copper and so is much quieter . Another advantage of PEX is that is doesn’t corrode like copper . PEX also is better to use than CPVC pipe, mostly because you don’t need to use glue to attach the pipe together.
