With drought conditions predicted to continue for the foreseeable future, we’re likely to water more often this spring and summer. Make every drop count – and keep us on track to meet our conservation goals – by performing routine maintenance to maximize your sprinkler system’s efficiency.
Monthly
Check for leaks by inspecting water lines, sprinklers, emitters, and other components. Look for wet spots in the landscape and listen for hissing to help locate issues.
Your irrigation system is only as good as its aim. Adjust sprinklers and emitters to make sure they’re delivering water to the landscape and not onto rocks, bare earth, or pavement.
Replace damaged parts immediately with identical or equivalent parts. This ensures uniform coverage and optimal system efficiency.
Locate and clean any clogged equipment.
Use water meter and historical data to help reveal hidden leaks.
Check to make sure irrigation controller is set appropriately for the season
Spring
As the watering season gets underway, check your irrigation system for leaks and clogged, broken, or missing sprinkler heads and emitters.
An outdated irrigation system can waste time, water, and money. Consider installing a new WaterSense-labeled, “smart” irrigation controller to take the guesswork out of scheduling (rebates available).
Set the controller for watering frequency, start times, and duration per zone per program.
Replace the back-up battery in the controller.
Test the manual shut-off or isolation valve.
Check the water pressure in each irrigation zone.
Check and clean filters, wherever they are in the system.
Check and clean the filter screen in each sprinkler body. Adjust the rotor arc or spray pattern to eliminate water waste.
Test heads to make sure they are delivering consistently and efficiently.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
Early Summer
Adjust controller for the appropriate seasonal setting.
Adjust sprinklers and emitters to make sure they’re delivering water to the landscape and not onto rocks, bare earth, or pavement.
Check and clean filters, wherever they are in the system.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
As plants grow bigger, move the emitters to the edge of each plant’s root ball or drip line to encourage further root development.
Fall
Adjust controller for the appropriate seasonal setting.
Test the manual shut-off or isolation valve.
Check and clean filters, wherever they are in the system.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
Winter
Guard your irrigation system against freezing temperatures by draining pipes and tubing and properly winterizing your system.
When temperatures are below 40 degrees Fahrenheit, discontinue automatic watering and turn on systems manually or hand water as needed.
Pressure regulators are another essential technology for improving the efficiency of your irrigation system. They are an integral part of keeping your system running in peak condition. Pressure regulators come in two basic styles: inline or valve fitted. An inline regulator attaches within the piping on a lateral line and is most used with drip irrigation. A pressure-regulated valve fitting is used more often with turf irrigation where the pressure is high.
These fittings can either reduce pressure or provide sustained pressure. Valve fittings are brand specific, so we suggest visiting a local irrigation supplier to see if they are available for your brand of valve. Pressure regulators provide the following benefits:
Avoid underwatering or overwatering by maintaining a set, optimal pressure.
For lawn irrigation, they reduce misting and excessive evaporation.
With a drip system, they help keep the emitters’ water output accurate and keep them from “blowing” or “popping” off the drip line due to excessive pressure.

Pro Tip: Jim from Site One irrigation supply store in Albuquerque says, “An inline pressure regulator is a must in any irrigation installation in Albuquerque. They reduce the chance of blowing out your drip emitters and even out the water delivery.”

Blue Mist spirea is particularly well suited for areas with dry climates. That makes it a significant staple in New Mexico landscapes. The flowers attract a variety of life that includes bumblebees, butterflies, and even hummingbirds. Once established, it is reasonably drought tolerant, too. Pick Blue Mist spirea to add a touch of color in your garden.
Irrigation systems have grown more efficient by leaps and bounds in recent years to maximize water savings. Now, many systems can even communicate with you via your smart phone or computer. There are some tried and true, if under-used, pieces of equipment you can add to your system that are inexpensive, easy to install and don’t require a ton of technical know-how. And the Water Authority is offering a rebate on them!
Flow sensors are inexpensive gadgets that can alert you of a broken line or a broken head in your turf. Flow sensors on main or lateral lines can be set up to “learn” what the normal flow for each zone is. The sensors then monitor the flow, and if there is a change in flow outside of the norm (either low or high), they will shut down the water line with the issue. A flow sensor provides the following benefits:
Some flow sensors can record and transmit how many gallons you use each time you water.
Flow sensors can save you hundreds or thousands of gallons of water by either shutting down a malfunctioning system, or warning you of one, or both.
Visit your local irrigation house to see which model and brand are compatible with your system and earn rebates of 25% up to $100 including purchase and professional installation. Learn more at irrigation efficiency rebates.
Pro Tip: “Flow sensors are great for all commercial installations and for savvy homeowners who want to know how much water their system puts out. The key is to not mix brands. Instead match the brand of your controller with the brand of your flow sensor. ” says Loren Dunlap of Sierra Irrigation, local supply store in Albuquerque.

Use a
pressure gauge to verify that sprinkler heads are operating at recommended
pressures, and check and clean all system filters.
Watering Recommendations: Time to follow our Spring Watering Recommendations. Remember, if it rains more than a half inch you can skip your next scheduled watering time as there is there’s no need for supplemental irrigation.
Your irrigation system is only as good as its aim. Adjust sprinklers and emitters to make sure they are delivering water to the landscape and not onto rocks, bare earth or pavement.
June is a great time to check and replace any clogged spray nozzles or drip emitters. Remember, each spray head also has its own filter insert that needs checked as well.
Watering Recommendations: Summer is here and so are hotter temperatures! Follow the Water by the Seasons Summer watering recommendations to keep your yard looking healthy. For turf, water 2-3 times per week. Start watering your trees and shrubs 1 time per week to keep them looking good.
Remember, if it rains more than a half inch you can skip your next scheduled watering as there is no need for supplemental irrigation.
