PEX Pipe vs. Copper Pipe - which is better?
Copper piping has been the standard of plumbing for more than half a century. Recently, competition has appeared in the form of PEX pipe. Each has its own advantages and disadvantages that are worth considering before your next remodeling project.
- Resists corrosion more than other metals like steel or brass.
- Can be used outdoors, unaffected by sunlight (UV).
- It’s fireproof and doesn’t release toxic gas in case of fire.
- Average cost of copper pipes is 4-6 higher than of the PEX pipe.
- Water could have metallic taste if copper is corroded.
- New copper plumbing systems may require chemical treatment to remove leftover solder from brazing the joints.
- Copper pipes are high likely to burst when water in the pipes freezes.
- More difficult to install than PEX tubing because of its rigidity, requires more PEX fittings and connections.
- Requires fewer fittings, easier to install, less likely to have a leak.
- Very cost effective, requires less labor.
- Can have long continuous runs without the need for couplings.
- Is able to expand and contract making it more burst resistant than copper, brass, and other rigid pipes.
- Has good chemical resistance.
- Pipes can be bent around almost any corner without an elbow fitting.
- Quieter, reduces “water hammer”.
- Recyclable mechanically, chemically, and thermally.
Can’t be used outside.
