Just like the original but sized perfect for one gallon jugs or smaller fermenters. Measures 13.5 inches top to bottom.
The inner tube acts like a plunger, pushing liquid against the check valve at the bottom of the outer tube. This action forces the liquid down the hose to start the siphon. Starting a siphon is as simple as pumping a couple of times then letting gravity do the heavy work!
Saftey Note: Autosiphons are NOT designed to be used with HOT WORT!
