Good question. I should update the documentation to include this.
It is a bit complicated because different board reves of the Raspi have slightly different pin numbering. Also there are a couple of different GPIO libraries that have different pin functions. And there are two ways to number the pins on the Pi, Physical and BMC.
If you are using a recent rev of the Pi you should be able to use physical pin 8 (BMC pin 14) for the rain sensor.
See this link for more info about the pins:

Let me know if this does not work.
