Easiest way I found to start a siphon comes from my waterbed days: with a
water hose, run water INTO the "to be drained" item, until the air bubbles
stop. Then disconnect the end at the water spout and drop the hose. It
will
drain immediately!

There are also devices sold in waterbed stores and pet stores that screw on
to a spigot. You rotate the device in one direction and it directs water to
down the hose, rotate it the other and the flow of the spigot is used to
start and force a siphon. Works very well.
