Cross-linked polyethylene (PEX) and copper are both standard materials for plumbing, each bringing its own set of benefits and drawbacks to the table.
When it comes to some applications, PEX is considered superior to copper. The reasons? Flexibility, resistance to corrosion, ease of installation, and cost-effectiveness. PEX can be bent to go around corners in a way that copper can't. And because PEX doesn't require as many fittings, it doesn't create as many opportunities for leaks, either. If you were to use PEX instead of copper in some plumbing job, you'd likely save money on labor, as well as on the materials themselves. A few years ago, a nice-length roll of PEX was less than half what an equivalent length of copper pipe would cost.
Conversely, copper has an extensive history of dependability, is long-lasting, and contains natural antibacterial agents. Its fire resistance is a distinct advantage, and it can be installed outdoors without worry of deterioration due to exposure to UV light, a drawback of PEX.
When deciding between PEX and copper, many commercial plumbing operations in Welby consider several factors. Need, budget, and installation location are the most common determinants. If a project only requires a low-cost, easy-to-install product, then PEX is the most likely choice. It is also the most common choice when the installation is not exposed to high heat or direct sunlight. However, if the installation is in a place where those two factors (high heat and direct sunlight) could come into play, copper is the better option.
