Bell Siphon - the Parts List

Folks have been asking for parts lists and drawings on how to put this together. So I've (finally!) put together a parts list, complete with links to the product pages for these bits on the Home Depot website. These are the links and prices in December 2011 - I'll try to update the links as they change over time.

Bernoulli Standpipe Inexpensive Bulkhead Fitting Coanda Discharge
Auto-siphon "Bell" Media Guard
All told, the parts add up to about $20 if you're just building a single Bell Siphon. If you build two of them, they come in at $14 apiece. Or if you get a bunch of friends together to build 10 of these, the price comes down to $9 apiece (because you'll buy the 10 foot long lengths of 2-inch and 3-inch pipe - economies of scale).

Small system I put together for a Feb 2012 science fair

Now that you've got the parts, here's how to put it together:

Installing the Bulkhead fitting (the grey conduit bits and O-ring)

Assembling the Standpipe, Bell, and Media Guard

Different Discharge Options (I like the 45 degree or Coanda Discharge)
