The "snorkel tube" on the top of the bell is nothing new. My bell would always "fire" but would not release at the end. I added a 1/4" piece of tubing to mine and ran it down to the grow bed. Works like a charm every time. I guess we each have our own experiences and have found a way to overcome problems as they arise. Just goes to prove the old adage, there's more than one way to skin a cat. No actual harm befell any cats during this posting. Just added that disclaimer for the PETA folks.
