Sprinkler System Maintenance Tips

Sprinkler System Maintenance Tips

Improve Your System’s Efficiency
and Avoid Costly Repairs 

Did you know that your irrigation system accounts for between 50% and 75% of your home’s monthly water usage?

Did you also know that more plants die from overwatering than underwatering?

Those are just two of the many reasons that regular maintenance is needed to keep your sprinkler system running efficiently year after year. Here’s another:  Damage from lawn equipment or improper winterization can result in costly leaks and other serious problems.

An Ounce of Prevention

Here are a few simple checks to perform on a monthly, annual or periodic basis to ensure your sprinkler system is operation at an optimal level:

Every Month During Growing Season…

Inspect the controller and make sure it’s plugged in and functioning.

Check the connection on all of the wires and sensors.

Adjust sprinkler head positions and spray patterns to avoid watering sidewalks or structures and to provide necessary clearance over growing plants.

Remove obstructions that prevent sprinklers from distributing water evenly.

Check the pressure. Pressure can change over time and negatively affect your system’s efficiency. If the pressure is too high, it’ll result in significant runoff.

Inspect your system for leaks — a huge water waster. This step requires the help of your irrigation contractor. He’ll not only check for leaks and broken or clogged spray heads; he can also advise you about common problems to watch for between visits.

Once a Year…

Winterize, winterize, winterize! This routine maintenance procedure is critical. Overlook it, and you can expect costly damage to your system. But this is something best left to the professionals. Your irrigation contractor has specialized equipment to flush out the water that could otherwise freeze, resulting in cracked pipes, valves and other parts. (See related article, “How to Winterize Your Landscape Irrigation System.”)

Get your back flow checked. Federal and state laws require that your backflow connection be tested annually by a state-certified tester. (This is typically part of the winterization process.)

Once in a While or As Needed…

Now and then, it’s a good idea to have your system audited. Hire a Certified Irrigation Auditor to conduct an audit and uniformity test. If your system is watering unevenly or improperly, he can make the necessary adjustments.

Replace your controller’s back-up battery whenever you replace your smoke alarm batteries.

Adjust the watering schedule to reflect the current season and irrigation needs of your landscape.

With the proper routine maintenance, your irrigation system will serve you well for seasons to come!

Water Scarcity Increases Irrigation Audits

Water Scarcity Increases Irrigation Audits

Irrigation Audits Becoming
Mandatory in Some Areas

Water’s continued scarcity is making irrigation audits more important than ever.

For example, the city of Aspen, Col., now requires that such audits be completed whenever a new landscaping system has been installed. And the audit must be performed by a third-party certified landscape irrigation auditor.

There’s only one problem: Such certified auditors are as rare as hens’ teeth in that area of Colorado.

A Host of New Regulations

The irrigation audits are part of a package of new regulations for the city, which also require that all new or substantially remodeled residential projects include a landscape plan, an irrigation plan and a water budget for the site.

In order to address the lack of certified auditors in the area, Aspen city officials hope to establish a local training program.

The city’s new water-budget goal for landscaping is to use no more than 7.5 gallons per square foot per season. So far, 17 properties have been landscaped and irrigated using the new regulations. Those projects averaged 7.2 gallons per square foot, according to a parks and utilities representative.

Aspen’s new landscaping regulations apply only to residential and commercial properties. They do not apply to “irrigation of public parks, sports fields, golf courses and schools.”

Increased Need for Auditors

Of course, the need for certified irrigation auditors is greatest in areas with water scarcity issues, like the Southwest. But water conservation and water efficiency are two separate goals. Even areas that typically receive adequate precipitation (like Ohio) could always benefit from increased water efficiency.

As the pursuit of improved water efficiency becomes increasingly popular (and important), the need for certified irrigation auditors will most likely increase, too. Irrigation auditing entails three steps:

  1. Collecting data
  2. Verifying that irrigation systems are working as designed, and
  3. Identifying opportunities to improve water efficiency.

An effective auditor will:

  • Analyze water requirements and irrigation use within the context of each site’s unique conditions.
  • Develop irrigation schedules based on water requirements, quality and availability.
  • Make maintenance recommendations to keep the irrigation system working reliably and cost effectively.
  • Estimate potential dollar and water savings from implementing innovative irrigation technologies, products and practices.

Where to Start?

To become a Certified Landscape Irrigation Auditor (CLIA) under the Irrigation Association’s program, a landscape contractor must:

  • Have at least one year of professional experience
  • Pass a written exam, and
  • Submit a completed water audit which includes one rotor and one spray area for evaluation (verified by an IA-certified professional in good standing).

According to Brent Mecham, the IA’s industry development leader, the CLIA program “shows that you have the expertise needed and that you’re better qualified to evaluate irrigation systems.”
