Spruce Up Your Sprinklers in April

/in , /by

Californians gave their irrigation systems the winter off in much of 2023 thanks to above-average precipitation. As the weather warms, the U.S. EPA encourages everyone to perform a maintenance check in April as part of its “Sprinkler Spruce Up” effort.

A sprinkler spruce-up involves four steps: inspect, connect, direct, and select. Cracks in pipes can lead to costly leaks, and broken sprinkler heads can waste water and money. System maintenance can help save money and water, up to 25,000 gallons of water, and $280 over a six-month irrigation season. April is an ideal time to spruce up your irrigation system.

Look for leaks and breaks

Because most irrigation systems run in the early morning, missing or broken sprinkler heads may go unnoticed. This can cause overflow or flooding on landscapes or waste water on hard surfaces.

Inspect your irrigation system and look for sprinkler heads that do not pop up fully or are tilted. Flag them so they can be located and repaired later. You may be able to do it yourself but call on a WaterSense-certified professional who can replace the broken sprinkler heads.

Check all connections

Leaks can occur at the joints between sprinklers and the piping. Leaking joints can also be caused by too much water pressure or particles in the water. Check to ensure your pressure regulator is installed properly.

Between irrigation cycles, look for water pooling on the surface of your landscaping. This could be caused by an underground leak. Check the connections inside valve boxes to make sure all the valves and other components are securely connected. If the valves cannot close completely, your system could slowly seep water even when turned off.

Survey your irrigation coverage

The greatest waste of water in <yoastmark class=

Irrigation water spraying on hardscapes instead of landscape plants is wasted down the stormwater drain. While your system is running, note any overspray and adjust sprinklers toward your landscaping.

For best results:

  • Each sprinkler should be able to reach the sprinkler head next to it, called head-to-head coverage.
  • Direct sprinklers for uniform coverage to avoid dry spots.
  • Maintain consistent water pressure so that nozzles can operate efficiently.
  • Upgrade to a smart controller. Weather and soil moisture-based controllers can automatically adjust your watering schedule.

The greatest waste of water in landscape irrigation comes from watering too much, too fast. Observe how water absorbs into the ground during the watering cycle. If water begins running off your landscaping or pooling, run sprinklers in multiple shorter sessions with breaks. This allows water to soak into the soil and minimizes runoff.

The checklist also provides additional irrigation and landscape tips and suggestions about when to call in an irrigation professional.

Fall Back and Adjust Irrigation Systems to Save Water

The end of daylight saving time is a reminder to residents to assess their outdoor watering needs and adjust their irrigation systems to reduce water waste – an especially important step after more than two years of statewide drought. Plants simply don’t need as much water during cooler months, and they typically don’t need irrigation at all after heavy rains. Using water efficiently indoors and outdoors is easier than ever thanks to online resources offered by the Water Authority at www.watersmartsd.org.

Fall Back and Adjust Irrigation Systems to Save Water

/in , /by

The end of daylight saving time is a reminder to residents to assess their outdoor watering needs and adjust their irrigation systems to reduce water waste – an especially important step after more than two years of statewide drought. Plants simply don’t need as much water during cooler months, and they typically don’t need irrigation at all after heavy rains.

“This is a great time to make sure irrigation systems are working properly and delivering the right amount of water,” said Jeff Stephenson, a water resources manager for the San Diego County Water Authority. “After two years of drought, using water efficiently and eliminating water-wasting practices is a critical part of preserving more of our precious supply.”

Adjust irrigation systems

Outdoor watering accounts for more than half of a typical household’s water use in California. Making seasonal adjustments to irrigation controllers can help reduce water waste and lead to healthier landscapes. Water-saving practices include turning off irrigation systems when rainstorms are predicted and leaving them off for at least a week after significant rainfall.

Using water efficiently indoors and outdoors is easier than ever thanks to online resources offered by the Water Authority at www.watersmartsd.org. The site is filled with information about conservation incentives, and it includes tools and programs designed to make the most of the region’s most precious natural resource. Saving water is easier than many people realize. A few simple changes can make a big difference – especially outdoors.

The 2021 water year was the driest in California in more than a century, but San Diego County continues to have reliable water supplies due to long-term investments in water sources and infrastructure, coupled with extensive water conservation efforts. Per capita potable water use in the San Diego region has decreased by nearly 50% since 1990 as residents and businesses continue to adopt WaterSmart practices.
