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? I'm gonna do a short 3/4" run under a house and then some 1/2" for toilet and shower supply lines. What should I use? not concerned with price as much as I am with doing a good job. Thanks all for your time and input, this sub has been a wealth of knowledge
