Garden hose venturi pump

thingiverse

Create a watering system for diluted liquid fertilizer by using a garden hose, as your worm composter generates excess fertilizer. To do so, print the designed venturi part and follow these steps: remove the support cylinder and cut the membrane; attach a rubber washer to the female threaded end; tap the vacuum port with a 1/8 NPT tap without force; insert your desired fitting into the port and connect it to your sprinkler. Make sure to use the revised STL file (venturi 3.5) for better results. This setup was last updated on 4/16/16 after fixing issues in the original design.
