Copper is the superior technology for plumbing. Not denying that. And it will look better to most people when done. And if you can solder, by all means this is the way to go.Hmmmm.. tested by whom and for how long? I'm pretty sure Roundup was tested as well..
In my humble opinion, copper just has a better rugged look to it. Awesome work for the first time..
But most people cannot sweat copper fittings. And as I said far above, sharkbites are expensive fittings. I only suggested CPVC, for future people who search this thread and think a DIY shower would be great but I cant solder and dont want to hire a plumber. As with just about anything I type here in these forums, I have 3 goals. 1.) Encourage and congratulate 2.) Offer any guidance to the OP that I might have 3.) Remember that what I type will help future people, just like when I search the forums to get answers.
So based upon #3, I simply wanted to offer a future tip.
But to the OP, this is awesome, job well done, congrats on a new skill, and its always nice to get to buy a new tool.
CPVC has been around since the 1950's BTW (and used very regularly in place of copper in the past couple of decades as the cost of copper has risen and copper thieves became a thing), as a DIY technique for people who are unable or scared to solder copper.
