I am replacing the bathtub in our house and in doing so will be changing out the shower valve, but after searching the forum and Google, I can't seem to find an answer to a question I have.
After exposing the current plumbing I noticed there is a little more than a foot of pipe that goes straight up and then just terminates (see picture). It is the same way for a pipe on the other side that leads out from the bathroom and into the kitchen.
What is the reason for this? Do I need to maintain the same setup when I install the new shower valve or can I just replace it with a 90 degree fitting that then goes straight to the new valve?
