What is PEX Plumbing?

PEX plumbing is a type of plastic that is cross-linked polyethylene. PEX pipes or piping can be used for water supply and radiant floor heating. There has been a lot of controversy surrounding PEX over the past few years because PEX has a few drawbacks that you might expect. Here are some of the issues:

PEX Plumbing Disadvantages. What You Need to Know

When it comes to considering whether or not to install or replace your plumbing, you’re undoubtedly perplexed by the choices. Even if you’re doing a minor job, things can get out of hand fast as you stand at the hardware store comparing materials, sizes, and forms:

PEX plumbing is something most people are familiar with, but you don’t know much about it if you’re like most folks. Every option comes with advantages and drawbacks, but it’s critical to understand the disadvantages of PEX plumbing so you can make an educated decision.

PEX Plumbing Disadvantages

  • PEX may leach BPA and other toxic chemicals

One of the key disadvantages of PEX is that it may leach chemicals like bisphenol A (BPA) and other toxins into the water supply. While the amount of BPA released isn’t considered dangerous in small doses, it’s still something to be aware of. A recent study found that nearly all PEX piping released BPA, increasing concentrations over time.

  • PEX is extremely sensitive to UV light

Another disadvantage of PEX piping is that it’s extremely sensitive to UV light and can degrade very quickly when exposed to the sun. This means that if you have a PEX pipe running outside or in an area with a lot of sunlight, it may not last very long.

  • PEX is harder to repair

If something goes wrong with your PEX plumbing, it can be a lot harder to fix than traditional metal piping. PEX piping is less malleable, so it can be difficult to get the pipe back into place if it becomes twisted or kinked.

  • PEX can be damaged by chemicals and pests

Finally, one more key disadvantage of PEX is that chemicals and pests can damage it. If you have a pest problem at home, they may be able to damage your PEX piping and cause water leaks. And if you’re using PEX for hot water supply, certain chemicals can cause the plastic to degrade over time.

  • PEX can’t be installed in high heat areas

One other important thing about PEX is that it can’t be installed in high heat areas. If you’re using PEX for a water supply line in an area where the water temperature is regularly over 140 degrees Fahrenheit, it could potentially cause the plastic to melt.

  • PEX is semi-permeable, which means liquid can enter the pipe

PEX piping is semi-permeable, which means that if there’s a leak in the pipe, liquid can enter it and cause damage to the surrounding area. This isn’t as big of a problem with metal piping, but it’s something to be aware of if you’re using PEX.

  • PEX the plastic issue

Although plastic piping is becoming more and more popular, there are some key disadvantages to using PEX tubing. Some of these drawbacks include the fact that PEX may leach harmful chemicals like BPA into the water supply, it’s very sensitive to UV light and can degrade quickly, it’s harder to repair than traditional metal piping, and pests certain chemicals can damage it. Additionally, PEX can’t be installed in high heat areas. So, before deciding on what type of plumbing to use in your home, be sure to weigh the pros and cons of PEX tubing carefully.

  • PEX the taste issue

Another key disadvantage of PEX piping is that it can leach chemicals into the water supply, giving it a strange taste. If you’re using PEX for your water supply, you may want to consider using a filter to get rid of any unpleasant flavours.

So, what’s the verdict? Why Is PEX Plumbing Not Right for You?

Well, that depends. PEX has some clear disadvantages compared to other types of plumbing, so it’s important to weigh all the factors before deciding. If you’re concerned about chemical leaching, UV light damage, or repairability, then PEX may not be the best choice for you. But if you’re looking for a budget-friendly option that’s still relatively durable, PEX may be a good choice. Just be sure to factor in all the potential drawbacks before making a final decision.
