Why is PEX plumbing bad?
Potential chemical leaching is another downside of PEX piping. Due to its chemical composition, the PEX pipe material may leach toxic chemicals including bisphenol (BPA), MTBE, tertiary butyl alcohol (TBA), and others.What material is used for drain pipes?
Polyvinyl Chloride pipes are the most commonly used pipes for any drainage project. Due to the material’s malleable properties, PVC pipes can come in almost any size. These types of pipes are great for drainage situations where the water and environment exert a great deal of pressure and weight.
How long does PEX pipe 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.

Should I replace copper with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
Which is better PEX or CPVC?
CPVC Pipes Offer Better Water Pressure Than PEX With PEX, the pipe fits around the outside of the fitting so the internal diameter of the pipe is reduced at each fitting—even when “full flow” expansion fittings are used. Depending on the fitting used, this can reduce the internal diameter of a ½” pipe by 21% to 35%.
