Funny... I just checked prices for soft copper last week. Unless I heard incorrectly, 1/2" is going for over 3 bux a foot. 1" is probably double that. Use PEx tubing. Very affordable and very resilient. Save yourself a small fortune. Go to your local plumbing supply house and they'll help you with what you need. Avoid big box stores. They don't know shit and their selection sucks. Answer from Deleted User on reddit.com

r/Plumbing on Reddit: Where to buy 1 to 1 1/8 inch copper pipe fittings?
April 3, 2021 -
Hi all!
I'm trying to research the parts necessary to replace my main water supply line with 1" soft copper tubing (1 1/8" OD). I'm trying to figure out how the copper connects to other pipes and I am having 0 luck finding fittings online for 1"+. I read flare fittings are great (to connect the copper to the main at the street) but the largest I can find is 7/8 OD. Can't find the correct size compression fittings either.
Where do y'all buy your parts at for these 1"+ pipes?
