I have 1.5" PVC pipe running between my yard shed and the house, a distance
of approximately 100 feet. I attached a ping pong ball to a piece of string
and dropped it in one end. I put the ball of twine on a nail so it could
spin freely. I then taped the hose from my shop vac to the opposite end of
the pipe. I barely got the vac turned on before I heard the ping pong ball
hit the hose. It worked great! I suppose a smaller ball would work as well
in smaller pipe.
