The spigot on the left does have water to it, I turned it on for a second only, it didn't feel hot, but maybe that wasn't long enough. The gray hose goes to drainage. The cold water also has water in it. The pipe directly above the spigot on the left is capped off right outside the picture. The people living here before had a washer and dryer, so I'm assuming they made it work somehow.
Can the left spigot be treated as hot and the left cold?
Thanks in advance for the help.
