Why Copper is better than PEX?

Copper is more likely to freeze and break. One of the biggest disadvantages of copper pipes is their tendency to crack if the water inside freezes and expands. Having a degree of flexibility, PEX is able to expand if the water inside it freezes, making PEX more resistant to freeze-breakage.

What are the disadvantages of PEX?

Is a PEX manifold worth it?

There are many benefits associated with both PEX tubing and PEX plumbing manifolds: … PEX is flexible and can be bent, so fewer fittings are needed than for rigid piping, which means less pressure drop occurs in the lines.
