Pros:

Durability: Copper has a life expectancy of 50-70 years.

High Temperature Resistance

Copper naturally inhibits the growth of bacteria, making more sanitary for drinking water.

Cons:

Cost: Material cost is more expensive than PEX.

Corrosion will happen in water conditions with high acidity.

Rigidity: Copper is very rigid, possibly making installation difficult in areas where pipes may need to bend or weave.

Pros:

Cost-Effective: PEX is much cheaper in comparison to copper.

Corrosion-Resistant: Unlike copper, PEX is not susceptible to corrosion, even in highly acidic water.

Color Coding: PEX can often be color-coded (red for hot, blue for cold), making it easier to distinguish during installation or repairs.

Cons:

UV Sensitivity: PEX cannot be exposed to sunlight for prolonged periods.

Temperature Limits: PEX can handle most household hot water needs, but it is not recommend for very high temperature applications.

Less Historical Data: Since PEX is newer material, it does not have the same long-term durability track record as copper.
