Okay, better idea of what I might suggest.
Semi bare basement wall so that a faucet might be hung on a stand, rack or some place, makes me like the idea of finding a cheap or salvage single handle faucet for the temperature control and then using some form of the "y" to get the hot and cold to that faucet. If it would fit better, the "Y" could even be added on the back of the washer, rather than at the first faucet. I like the second faucet as a single handle gives me less to think about when I'm filling the tank. Swing it one way for warmer or the other way for cooler! Not necessary but since I find lots of old faucets set out on the curb, I like the convenience for little extra expense. I don't like adding any type of T in the water lines to the washer since most of us do leave the faucets open and I am not real happy with the way some fittings fit hoses of this type. Just paranoid about floods, maybe?
A more "upscale" look might be found by using PVC or CPVC off the "Y" to get to the faucet?
