Which end is Start and Finish? (Graphic ambiguity)

[a-raccoon]

Please replace the starting end with a garden water spigot or valve. I always have to test which color the water comes from because I'll often start from the wrong side.

Well, it always starts from the right. But if you like you can design a nice new icon that fits well into the overall design and I will replace it..
