Actually I've seen recommendations of turning the outlet 90 deg. vertical to help prevent air from gurgling back up the pipe & stoping the siphon.

My only complaint of a siphon is when used to drain a pond for some reason (which happened to me at least twice) the siphon stops it is very difficult to get started again with the water level down in the pond.
