Q: Which drinking valve should I choose, Original or Vari-Flo?
A: That depends on what species of animal or bird you have and its size. The Vari-Flo Valve is smaller and is ideal for small birds because it is easier to activate. The Original Valve is slightly larger and appropriate for larger birds. We also have special drinking valves available for large parrots, and cup waterers for domestic fowl.
*The African Grey can drink from the Original or Vari-Flo valve. For this particular bird, it is important to use the threaded drinking valve and install in a rigid pvc pipe system. Note: The drinking valves marked for each of the animals (except guinea pig) are the preferred valve choice, but it is possible to use either the Original or Vari-Flo valve.
