Quick Answer: Is PEX OK For Drinking Water?

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..

Does PEX affect water taste?

But Whelton said scientists are still making sense of the data around this new kind of pipe. Already, research shows that PEX pipes can have an impact on the taste and odor of tap water as compounds escape the pipes.

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?

Is PEX plumbing good or bad?

While PEX is generally considered a safe product and accepted by building codes, the materials and components that comprise the system have several vulnerabilities, and several defective fittings and systems produced by various manufacturers have resulted in leaks and system failures.

What is the lifespan of PEX pipe?

100 yearsAdditionally, 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.

What type of PEX is used for drinking water?

There are no performance differences between red, white, blue and white PEX and all are intended for use in potable water systems. The colors can be used to easily distinguish between hot and cold distribution lines. Orange PEX pipe is an oxygen barrier PEX pipe used only for hydronic heating applications.

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 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. Copper pipes can last anywhere from six months to the life of a building.

Should I use PEX A or PEX 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 safer than copper?

PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. … Attaching PEX tube to fittings does not require soldering, and so eliminates the health hazards involved with lead-based solder and acid fluxes. PEX is also safer to install since a torch is not needed to make connections.

Can rats chew through PEX pipe?

The poison that is often used to kill small animals causes them to become very thirsty and seek water. Rats appear to be especially clever and can discern the sound of water flowing through PEX pipes – then rapidly chew through the PEX to access water.

Can I use blue PEX for hot water?

Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. … There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines. Other types of PEX include PEX-Aluminum-PEX, which is often orange, and PEX for reclaimed water, which is usually purple.

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.

What are the disadvantages of PEX?

PEX Plumbing DisadvantagesPEX 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 replace copper with PEX?

If it’s a small area that’s leaking, you could just replace that section with either PEX or copper. … Second, PEX costs less than copper. Coupled with the quicker installation, the savings over installing copper pipes can be significant. Also, PEX pipes don’t corrode like copper and aren’t susceptible to freezing.

Should I insulate PEX pipe?

Pipe insulation is a prudent step to take. Not only does insulation promote energy efficiency, but it can also reduce potential problems with moisture and condensation. … That’s because PEX pipes—basically a type of plastic—are physically different from other common piping materials.
