I am re-purposing a room that used to be a bathroom and in the process I need to terminate drains and supply lines.
The supply lines are 1/2" copper coming up through the concrete slab. I don't know where the lines come from and where the most immediately upstream manifold is at.
In order to not have a dead end supply lines, I decided to take those two supply lines, and turn them 180 degrees - instead of coming into the old bathroom, I will route both pipes through the exterior concrete wall and put hosebibs on them from the outside.
But that means I will have two hosebibs, one hot one cold. How would someone know which hosebib is cold and which hot? Is there some sort of convention when two hosebibs are mounted on the outside wall?
Left hot right cold? Buy two hosebibs with different color handles - red hot blue cold? Put a hose threaded cap on the hot to avoid access except to drain it once in a while?

Interesting. However I am not sure I want to tie them to an outside faucet as I want the two copper pipes to terminate at the concrete wall with only the male threads protruding. This would require me to do something specific to make the faucet connection that cannot be changed back to a standard hosebib without breaking some concrete.
Also the hot side would never be used as the cold water is like 80 degrees in Miami year round so I will only be flushing out the dead hot line.
I am leaning to mounting the hot on the left, with a red handle, and cap off the end of the spout. Or possibly use one of those bibs with a removable key handle for the hot?

I assume you also know that you CANNOT just solder 90s on the pipes and then extend them.

Codes say you CANNOT "soft solder" ANY copper joints under the floor. THey have to be brazed.

YOUR inspectors allow soldering joints under a concrete floor.

also, what is the fitting on the left side copper pipe where I put the red circle around?
Is this a coupling with compression connection on each end?
A close up picture.
There is no sleeve around the pipes either. Urghhh...
On the left side I think I am going to take that fitting apart and extend it from there. I hope that fitting hasn't crimped the copper if so I have to cut it a bit shorter. I don't anticipate a big problem.
On the right side, I am tempted to go to the coupling just above the floor just to reduce the number of fittings. I could leave that coupling alone and take apart the tee above it. The branch of that tee goes to a valve for a toilet both of those are eliminated as well. My concern is if I remove that lower coupling if the pipe is out of round or whatever I might be creating a bigger problem. Any suggestions? Extend from the lower coupling or change the tee out to a coupling?
