Pex Pipe vs Copper Pipe – Difference Between Pex Pipe and Copper Pipe

Copper Pipes

Pex pipes

• Copper creates a perfect biostatic environment (It does not allow for the growth of bacteria inside pipes).

• Pex pipes are not as effective as copper pipes in this aspect.

• Corrosion resistance is offered by copper pipes. But to a large extent, it depends upon the pH level of water.

• Corrosion resistance is much better.

• Copper pipes can be used outdoors due to its UV resistance.

• Outdoor use is restricted due to its reduced UV resistance.

• Copper has high thermal conductivity. Though this is a favourable property in several applications, it is a problem for piping. It can lead to heat loss in hot/cold water.

• Heat loss is not a problem.

• In cold climates, as a result of its thermal conductivity, copper pipes cause water to freeze. Excess freezing exerts pressure on the pipes and causing them to burst.

• The pipe bursting problem does not occur with pex pipes.

• These need to be soldered and the best is to practice using a vise before practically attempting to use them.

• These are easy to handle and fit. Hence, they are more preferred for small level indoor piping.

• Copper pipes are expensive with prices up to 10 times that of its pex counterparts.

• Pex pipes are cheaper.

• Recycling can be considered with these pipes.

• The lifespan of these pipes is relatively short and hence, recycling is not considered as an option.
