Wait, you are buying equipment before you even know if it's even able to work.

Then you post a photo of some faucet on the internet instead of asking your landlord or whoever put this thing on the wall.

And you are about to put that rusty piece of 100 year old with paint on it into operation? When was it last checked? Is it tight? Are the pipes all right? Where's the counter when it's gas/water/whatever? Who is the provider?
