I am replacing my old galvanized supply pipes with new cpvc pipe inside the house. For the pipe leading to the outside faucet, I will keep the last 6 feet of the run as galvanized to reduce the chance of freezing and cracking.

However, since I am replacing all of the pipe leading up to it, I thought about connecting both the hot and the cold water supply to this pipe. That way, I can still wash my car on a cool day with hot water if I choose.

My question: If I put a valve on each of the two supply pipes (1 valve for the hot, 1 valve for the cold) and then connect the two with a tee to the outside faucet pipe, does this follow most codes?

I guess I'm a little concerned that I could end up having cold water head backwards through the hot supply if I were to ever lose pressure on the hot water side (or vice-versa).

Your right, you will cause the hot and cold to mix, when both valve are on.

I'd just run two bibbs to the outside, one for the hot and one for the cold then when you want to mix the two use a splitter.

Like this.
