A typical garden hose delivers 5 to 10 gallons per minute (GPM).

The flow rate of a garden hose depends on several factors, primarily the water pressure from your source and the diameter of the hose. Higher pressure and wider hoses generally result in a greater GPM. This rate is crucial for tasks like watering plants, washing cars, or filling small containers efficiently.

Understanding Garden Hose Flow Rate

The volume of water a hose can deliver is measured in gallons per minute (GPM). This is influenced by:
  • Water Pressure: Measured in pounds per square inch (PSI), higher PSI means more water flow.
  • Hose Diameter: Wider hoses (e.g., 5/8 inch or 3/4 inch) allow more water to pass through than narrower ones (e.g., 1/2 inch).
  • Hose Length: Longer hoses can sometimes reduce flow due to friction.
  • Nozzle Type: Some nozzles restrict flow more than others.

Factors Affecting GPM

Hose Diameter and GPM

The diameter of your hose significantly impacts its GPM.

  • 1/2 inch hose: Typically delivers around 5-7 GPM.
  • 5/8 inch hose: A common size, usually provides 8-10 GPM.
  • 3/4 inch hose: Offers higher flow, often 12-15 GPM.

Estimating Water Usage

Comparison of Watering Methods

Watering Method Estimated GPM Time to Fill a 5-Gallon Bucket
Standard Garden Hose (5/8 inch) 8 GPM 37.5 seconds
Soaker Hose 1-2 GPM 2.5 to 5 minutes
Sprinkler (oscillating) 3-5 GPM 1 to 1.7 minutes
