1" PEX to copper


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.

Ya run Pex all the way to the softner, there's nothing to be gained by using copper.

How do I come out of the wall with 1" PEX. I want to make this a nice install. The softener does actually have its own bypass valve/manifold, so maybe I can just put a couple of shutoff valves. I don't mind investing in tools, wife still buying properties, I'm still the manual labor.

Brass pex fittings are spendy- consider the high impact plastic ones.

Plumbing on medical leave, and then he will wonder where his job went. Oh well, at least his water will be softer.

I like the pex expansion tool over the crimp tool. Pex has a memory. So once expanding and you put the fitting in. It will go back to its original size.



They make cheaper expansion tools

I guess another question I need to ask is do I need to stay with 1" copper on 1" PEX, or is 3/4" copper the way to go for the main line? I know there are differences in the inside diameters.

Thanks for all those that helped. Measured yesterday and it turns out its 3/4" pipe. Found a wall that runs under the pipe directly and it's going to turn out to be an extremely simple job. I'm starting to like PEX better then copper.
