I am replacing a shower faucet. The previous install soldered the copper to the shower valve but I am considering using threaded copper in case I ever need to replace it. What are the pros and cons of each type of install?
In all my years, threaded or soldered, I've never replaced a valve with the same valve, and definitely not with the threaded connections. If you think about the logistics of unthreading a shower valve to reuse the connections, you'll see what I mean.
I've come to the conclusion that the threads are for convenience of installation, not re-use.
