The Porcelain Faucet is a fluid transportation solution from Ceramics. It is used to transfer fluids from the side of one storage solution to the top of another; in other words, it functions diagonally downward in the direction it is facing.
Right clicking a placed Faucet will begin pouring fluid, if it is set up correctly. It will continuously pour until it either has no fluid left to pour or there is no room in the destination storage solution. Right clicking a Faucet while it is pouring will stop it.
