I have something like this on my sink in the basement, except it's plastic, and green, and I can run 2 hoses off of it, or leave a hose on 1 side, and the spigot on the other.
Ya, thats kinda what I have in my basement behind my washer.. I updated my post to show what I did in the basement. I used the same thing but only place I had water was behind the washer. So I took two of those type adaptors and put one on the cold and one one the hot. Still allowed me to keep the washer hooked up so the wife is happy and then that left me an open side of the adaptor still for cold and hot, I added a rubber Y to them and it goes down to one outlet now. Easy to keep a hose hooked up. And since those type adaptors we have have a on/off valve, makes it easy to turn water on and control the temp I want..
