Aquaponics Bell Siphon

thingiverse

This is an advanced bell siphon system designed for efficient aquaponics grow bed performance. It seamlessly fits over a 1 1/4" schedule-40 PVC standpipe, ensuring smooth water flow. A unique helical channel within the wall cleverly breaks the siphon, mirroring the popular "snorkel" design found in many bell siphons. However, I encountered issues with the original siphon breaking due to excessive inlet flow rates. To address this problem, I incorporated a delay mechanism into the helical tube, allowing water to drop before air enters the top of the bell. Following 30 minutes of thorough testing, this modification appears to be effective. The two lower-body threaded extensions are optional and serve as additional siphon breakers, extending their functionality. A crucial hole in the top enables the attachment of a 1/4" tube for remote siphon breaking purposes. You may choose to seal it depending on your specific needs. update: Additional files have been added to support compatibility with 3/4" standpipes.
