What pipe did you use? I was recommended Pex. Which I found fairly easy to install.
I've done everything I replaced in copper. It was all I knew at the time. Ive had great success soldering my stuff (new..old is 75/25 success/failure i never seem to be able to get 40 year old copper clean enough. Even bought a pipe cleaner that goes on a drill)
Now I've done 2 big plumbing projects for other people and we used pex. I wish i had used pex! I knew nothing about it prior to these installs. I have a crimp tool now and experience with it.
I will redo what I have left in copper and one day when it fails. Probably many years from now ill replace it with pex.
