I've recently been asked to help a coworker out that is on medical leave to install a water softener. I've worked with copper for a couple of decades on my own properties but not with PEX. I want to put copper in the wall with the bypass and shutoff valves. The supply line is 1" PEX. Can I use 3/4 copper? Is there a better way? This run adds a total of 12ft to the entire run.
