Why Is Pex Banned in California: An Indepth Analysis of Plumbing Regulations
Why Is Pex Banned in California?
PEX piping was banned in California due to concerns about potential chemicals leaking into the drinking water.
The ban was implemented before 2010 and, although it has since been allowed with an environmental review requirement, PEX can still be used in certain counties and cities under local jurisdiction approval.
The ban was based on worries of water contamination from PEX pipes.
However, the industry conducted an environmental impact review to ensure the safety of PEX products, and after legal battles, PEX is no longer banned in California.
PEX is a reliable and durable thermoset plastic for water pipe use, preferred by plumbers and builders for its ease of use and flexibility compared to copper piping.
Third-party testing has confirmed the safety of PEX, and it is widely used in other states without evidence of health risks.

Did You Know?
1. PEX stands for cross-linked polyethylene, which is a type of flexible plastic tubing commonly used for plumbing systems.
2. While PEX is widely used and approved in the majority of states in the United States, California prohibits the use of PEX pipes for plumbing applications.
3. The main reason behind PEX being banned in California is due to concerns about the potential release of toxic chemicals into the water supply from the plastic tubing.
4. California has stricter regulations and standards for plumbing materials compared to other states, which is why PEX is not allowed.
5. Instead of PEX, California primarily relies on copper pipes or CPVC (chlorinated polyvinyl chloride) pipes, which are considered safer and meet the state’s plumbing code requirements.
Initial Ban And Environmental Review
The ban on PEX piping in California was implemented before 2010 due to concerns about its potential impact on drinking water. California officials worried about the chemicals used in the manufacturing process of PEX pipes seeping into the water supply. However, in recent years, the ban has been lifted, albeit with certain regulations in place.
Following the initial ban, the state of California required an environmental review before allowing the use of PEX piping. This review aimed to assess the potential risks associated with the use of PEX pipes and to ensure the safety of consumers and the environment. It specifically addressed concerns about chemical leakage and any potential negative impacts on drinking water quality.
Concerns Of Chemical Leakage Into Drinking Water
One of the primary reasons for the ban on PEX piping in California was the concern that chemicals used in the manufacturing process could potentially leak into the drinking water. PEX is a thermoset plastic, meaning it cannot be remelted once processed, making it reliable and durable for water pipe use. However, there were worries that certain chemicals used in the production of PEX pipes, such as by-products of the cross-linking process, could contaminate the water supply.
Experts raised concerns that prolonged exposure to these chemicals could have adverse health effects on individuals who consume the water. However, it’s worth noting that there have been no concrete scientific studies linking the use of PEX piping to negative health outcomes.
Local Approval For PEX Usage
While PEX is generally banned in California, there are exceptions to this rule. PEX piping can still be used in certain counties and cities within the state, but only with the approval of local jurisdictions. This means that the decision to allow the use of PEX pipes lies with the local authorities who conduct their own assessments and evaluations.
Local jurisdictions analyze the potential risks and benefits of using PEX pipes and then decide whether to permit their usage. This decentralized approach allows for flexibility in regulation, recognizing that different areas within California may have varying circumstances and requirements.
PEX Industry’s Environmental Impact Review
To address concerns regarding the safety of PEX piping, the industry conducted its own environmental impact review. This review aimed to assess the potential impacts of PEX pipes on the environment and human health, providing concrete evidence to ensure their safety and reliability.
The review was conducted through rigorous testing and analysis by independent third-party experts. These experts thoroughly examined the materials used in PEX pipes, evaluating their resistance to chemical leaching and determining their suitability for use in potable water systems.
The results of the review confirmed that PEX pipes are safe for use with drinking water, reinforcing the industry’s stance on their reliability and durability.
To summarize, the industry’s environmental impact review, conducted by independent experts, has verified the safety and suitability of PEX pipes for use in drinking water systems.
PEX’s Legal Battle And Lift Of The Ban
After years of legal battles and debates, the ban on PEX piping in California was eventually lifted. The decision was made based on the evidence presented during the industry’s environmental impact review, the input of local jurisdictions, and discussions among experts.
The lifting of the ban acknowledges that PEX pipes are widely used in other states without evidence of significant health risks. Plumbers and builders favor PEX for its ease of use and flexibility compared to traditional copper piping. The removal of the ban also recognizes the industry’s efforts to ensure the safety of PEX products through comprehensive testing and evaluation.
while PEX piping was initially banned in California due to concerns about chemical leakage into the drinking water, subsequent environmental impact reviews and legal battles led to the gradual lifting of the ban. PEX pipes are now allowed for use in California under specific conditions, with local jurisdictions having the authority to determine their usage. The safety and reliability of PEX pipes have been supported by third-party testing, reinforcing their value as an alternative to copper piping for plumbing applications.

Frequently Asked Questions
Is PEX pipe legal in California?
Yes, PEX pipe is now legal in California. The California Building Standards Commission voted unanimously to add PEX potable water pipe to the California Plumbing Code. This means that even though the change will be officially reflected in the CPC in August, the use of PEX pipe is already approved and can be used immediately.
Why do plumbers not use PEX?
Plumbers may choose not to use PEX pipes due to concerns regarding their vulnerability to rodent damage. Despite their thickness, PEX pipes can still be susceptible to cracking or breaking when exposed to rodents, which can be a potential issue in certain environments. Additionally, while rare, there have been reports of PEX pipes leaching harmful contaminants such as BPA into the water supply. Although this may not be a common occurrence, it could be a reason why some plumbers opt for alternative pipe options to ensure the safety and integrity of the water supply.
What is the PEX controversy?
The PEX controversy refers to a issue that emerged in the late 90’s surrounding certain PEX piping systems and their use of yellow brass fittings. These fittings experienced a phenomenon called dezincification, causing premature failure of the piping system. As a result, a series of class action lawsuits and subsequent settlements were filed to address the damage caused by this issue. This controversy brought attention to the potential risks associated with specific materials used in PEX piping systems and highlighted the importance of ensuring the integrity and durability of plumbing infrastructure.
Is PEX banned in NYC?
Yes, PEX is approved for use in certain applications in NYC. While it is allowed for heating pipes in baseboard heating systems, it is not permitted for use in the hot water supply pipes specifically for showers. This decision likely stems from safety regulations and concerns regarding the potential and increased risk of hot water leaks or failures with PEX piping in high-temperature environments. The restriction ensures that appropriate materials are chosen for hot water systems to maintain the safety and reliability of the plumbing infrastructure in NYC.
