r/Plumbing on Reddit: type M, L or K?
April 1, 2017 -
If I'm trying to do the best job possible, which type of copper pipe do you all use regularly? is type M too thin for most applications? is type K prohibitively expensive, hard to work with or just unnecessary for general applications? is type L the Goldilocks of copper pipe or do I have it all wrong?
