What Is A PEX Pipe And
Why Is It Important?
Also referred to as cross-linked polyethylene, a PEX pipe is a synthetic, thin piece of plastic piping that can bend and mold however you need for it to fit in a space. It has great thermal properties and is 100% resistant to acids, so if you have particularly finicky water with a pH below 6.5, it's a better pick than copper, which will corrode in no time.
While PEX pipes can last about 50 years, there are some cons as well. They need a week-long flushing regimen when first installed to eliminate any chemicals or BPA and should be wrapped in a sleeve to prevent any contamination — make sure to place them away from water heaters and recessed lighting as they are quick to fail when overheated.
The average cost to refinish a standard-size home with PEX pipes is between $4,200 and $6,000, depending on your home and the location of the pipes. Fortunately, PEX pipes are about less than half the price of copper at $.50 to $2 per square foot, but it’s best to do research and receive a quote from a professional to make the final call.
