Definition

Comparison should include:

  • Wet barrel hydrant
    • has water in the barrel up to the valves of each outlet
    • is used in areas that are not subject to freezing temperatures
    • is controlled by independent valves that allow for additional connection without main shutdown.
  • Dry-barrel hydrant
    • is used in climates with freezing temperatures
    • is controlled by valve at the base that requires main shutdown to add connections.
