What is the Typical Water Pressure for a Sprinkler System?
Sprinkler systems are automated irrigation systems designed to deliver water to lawns, gardens, and landscapes efficiently. They consist of a network of pipes, valves, and sprinkler heads strategically placed throughout the area to be watered. Sprinkler systems offer numerous benefits, including water conservation, convenience, and improved plant health. Whether used in residential yards or commercial landscapes, sprinkler systems are vital in maintaining green spaces and promoting healthy plant growth. Keep reading to learn more about the typical water pressure for a sprinkler system and tips on how to get it right the first time.

Average Water Pressure For A Sprinkler System

The average requirements for sprinklers can depend on the type of sprinkler. Water pressure is measured in pounds per square inch. For residential and small business applications manufacturers recommend 30psi at the head for sprays and 45 psi at the head for rotors. Larger heads will require higher pressure.

Imagine a firehose compared to a handheld sprinkler. Firehoses would measure a much higher psi rating. A high-pressure hose should never be pointed toward most plants.

A typical sprinkler system should not exceed 12 gallons per minute (gpm) on a 1” service. GPM will fluctuate based on service size but should never exceed 5 feet per second in flow, otherwise water hammer will occur.

Measuring Water Pressure in Your Sprinkler System

Measure static (stationary) water pressure at the source before attempting to diagnose or adjust anything further down the line.  The source, usually a tap or reservoir, tells you the baseline of what you’ve got to work with. If any of your water sources are not fully open, it can also cause pressure or volume issues.

If dynamic (moving) pressure down the line measures significantly less than at the source you may have a leak or sprinkler head issue to fix.

Is Water Pressure Adjustable?

Installing flow control valves for each of your sprinkler zones allows homeowners to adjust the pressure for each zone.
Having a pressure regulator installed at the inlet source can help keep pressure in check. Make sure your regulator is set to not exceed 80 psi to prevent issues with the plumbing system.

Why Are Sprinkler Pressure Adjustments Needed?

Adjustments are made for more efficient watering. Water pressure isn’t always perfect straight from the first setup. Here are some reasons why adjustments are made.

  • Ensures less waste of the municipal water supply
  • The right amount of water gets to where gardeners want it to
  • More control over the garden and its irrigation
  • Some plants are more sensitive and need reduced pressure on them
  • To meet manufacturers’ recommendations
  • Uniform water distribution

How to Make Sprinkler System Pressure Adjustments

Water pressure can be adjusted in various ways. This includes installing or adjusting the pressure regulator, using flow control valves, or renozzling sprinkler heads.

Modern sprinkler systems have apps that allow you to control or get information from anywhere using your smartphone or laptop. Some apps can:

  • Tell you if electrical issues arise
  • Pressure regulating monitor
  • Monitors water flow
  • Gives users instant feedback
