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

r/Plumbing on Reddit: Copper re-pipe type L/M
June 17, 2022 -
I remodeled my house a decade ago, but the contractor cut corners and left some old galvanized pipes.
I'm having it re-piped, but I'm getting quotes saying they'll use and replace existing copper pipes with type L. Is that necessary or useful?
Top answer 1 of 4

In places with bad water quality L is much better and will buy you an extra 10-20 years of life. If you have decent water quality type m can still last 30-50 years easily, but only if properly installed. Number one failure is caused by not reaming the pipe, this causes cavitation in the water which will cause pinholes eventually. This will happen to L also if not reamed but will take much longer. From there it is a preference issue.
