Adjustable Standpipe Funnel for Bell Siphon

In aquaponics systems, a common way of irrigating beds is to use flood and drain using a bell siphon. For the bell siphon to work properly, the water must flow into the standpipe equally on all sides. This is a problem is the standpipe is either not completely perpendicular or the face is angled. The picture above of the raw standpipe shows the problem. When this happens, the siphon may not reliably start.

This thing is a ball and socket adapter that allows you to adjust the funnel so that water flows equally on all sides. It is also tapered which promotes proper autosiphoning behavior. There are two versions for 3/4" and 1" standpipes.

The funnel ball just snaps into the pivot base.
