Why is PEX banned in California? It’s not because of the health hazards it poses or the concerns about its environmental impact. In fact, PEX has been on the market in California for decades and has had no reports of serious health or environmental hazards. However, since late 2021, the California Health Department has advised businesses to not use PEX for plumbing systems.
Why was PEX banned in California? In 2021, the California Health Department advised all commercial plumbing contractors to not use PEX tubing for domestic plumbing systems because it could potentially cause health problems. Since then PEX has been allowed to use PEX for plumbing within California. So until the new piping can be approved by the state, PEX will continue to be used by plumbers.
Is there a better alternative to using copper or PEX in the plumbing system? Yes. There are other metals that are more durable than copper and most are also considered “green” – meaning they are friendly to the environment. These other metals include lead, iron, zinc, brass and stainless steel.
Plastic pipe is not considered green, because it uses hard copper tubing in its manufacturing process. Because PEX uses hard copper tubing, the resulting plastic pipes are considered to be even more harmful to the environment than regular PEX. That’s why the state of California has banned PEX use in residential plumbing. In addition to that, some cities, like Los Angeles, have also banned plastic pipe because of the same reasons as the state.
However, the biggest problem with PEX (or plastic pipe) is that it is very difficult to repair. Plastic pipes are not easy to disassemble and fix. In fact, if you try to repair a plastic pipe, chances are you’ll make many more mistakes than you would have before. The reason is that plastic pipe is so lightweight and thin – usually too small and delicate to be able to carry out major repairs. Furthermore, the material doesn’t lend itself to being welded. So basically, any attempts at repairing the pipe will be very minor, if ever.
A more obvious problem with PEX piping is the contamination of groundwater. PEX is easily leached into the ground water, which can eventually contaminate nearby aquifers. Furthermore, excess PEX in the soil can eventually Leach into the tap water, especially during heavy rains. This can lead to huge problems for the local water supply. Studies show that excessive use of PEX can lead to significant increases in the level of chloroform gas in local streams and wells.
Another major problem with PEX pipes is the danger of fire. If a hot-water pipe is overloaded, it can easily burst and cause injury or death. This happens particularly often with plastic pipes that aren’t properly installed and/or have been painted with fire retardant paint. The result is that when a PEX hot water heating system bursts, it releases dangerous fumes such as carbon monoxide and hydrocarbons into the atmosphere. This has been shown to be particularly dangerous to pets and people that live nearby.
The above problems with PEX plumbing should have been enough to warn people about the dangers of using this material, but unfortunately they’re not. To make matters worse, many people end up making their own home plumbing fixes to fix the problems with their plumbing. Unfortunately, this can be very dangerous. Improper repairs can lead to leaks, burst pipes and fires. If you’re thinking about fixing your own plumbing, you should be extremely careful and thoroughly read any instructions before you do it. You may find that your tools and skills are simply not sufficient to fix your own plumbing system.
