What is PEX used for?
What Are PEX Pipes? PEX is short for cross-linked polyethylene. PEX pipes, which are used for radiant heating and cooling systems, water piping, and insulation for electrical cables. PEX can be bent, twisted, or crushed, to some degree, and it will return to its original shape.
Why is PEX bad?
The chlorine in the water inside PEX pipes speed-up the brittle oxidative failure of cross-linked polyethylene. This failure leads to sudden leakage and sometimes even bursting of the pipes. Now, the chlorine degrades the antioxidants first but eventually ends up reaching the pipe and causing failure.
What are the disadvantages of PEX?
PEX Plumbing Pipe Disadvantages While PEX has numerous benefits, it should not be used outdoors. PEX is vulnerable to UV rays, which leads to premature degradation and it will not withstand outdoor conditions of extreme cold. PEX is engineered only for indoor use. PEX can’t be recycled.
Should I use PEX or copper?
We generally belive that Plumbing PEX Tubing is much better than Copper for most, if not all, plumbing systems. 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. PEX Tubing is quickly becoming the industry standard.
Is PEX plumbing safe?
While PEX plumbing may leach contaminants into your home’s tap water, limited research suggests it’s still safe to use. But as more consumers turn to PEX piping for its affordability and ease of use, it’s unclear whether PEX tubing may negatively impact water quality.
Is PEX better than PVC?
When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)
Is PEX OK for drinking water?
There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.
How long does PEX 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.

Is PEX safe for drinking water 2021?
With a plumbing-pipe offering in sizes up to 3 inches, PEX is challenging traditional copper and CPVC materials for domestic water applications. This provides confirmation the pipe does not leach harmful substances into drinking water and is safe for potable systems in healthcare facilities.
Should I replace copper pipe with PEX?
The installer recommends replacing my copper pipes with PEX. If so, you could get another 23 years out of your copper pipes and spare the cost to replace plumbing. If it’s a small area that’s leaking, you could just replace that section with either PEX or copper. Both types are interchangeable.
