• Remove old water lines
• Bring water system up to new code
• New water line installed with PEX pipe

PEX and CPVC cost about the same. But there are a few reasons why PEX may be a better choice.

First, PEX doesn’t require glue, which means you don’t have to work in well-ventilated spaces or wear a respirator. PEX is less likely than CPVC to burst if it freezes. Also, since PEX is more flexible and is available in long lengths, it can work better for “fishing” through walls in remodeling situations.
