Las Vegas heat is brutal on irrigation, and a sprinkler system that looks fine in March can fail completely by July. Running a sprinkler checkup before the temperatures climb is the single best way to catch a small problem before it turns into a dead lawn or a water bill you don’t want to see. Whether you’re in Las Vegas or Henderson, the desert climate and caliche soil put the same stress on every system in the valley, and a quick seasonal check now can save you hundreds later.
Why Sprinkler Systems Fail in the Desert
Most local yards run two systems side by side: sprinklers for grass areas and drip lines for planters. Drip sprinkler systems are more water-efficient and, when installed correctly, can run for 10 years or more. The problem isn’t the technology. It’s the installation. A huge share of the systems we inspect around Las Vegas were put in with thin, cheap pipe, undersized pop-up heads, or no swing joints at all. Those shortcuts don’t show up right away, but they show up eventually, usually as a cracked line, a stuck valve, or a section of lawn that just won’t green up no matter how much you water it.
A properly installed drip system can run hundreds of plants off a single station. That only works because the emitters are low-pressure, so every plant on the line gets the same amount of water instead of the first plant flooding and the last one starving. Get that installation right the first time and you’re not calling anyone for years. Get it wrong and you’re fighting the same issues every season.
When to Check Your Sprinklers
Irrigation checks matter most from April through October, when the Las Vegas climate is hardest on plants and lawns. During those months, we recommend:
Grass and sprinkler zones should be checked weekly, since lawns show stress fast in this heat. Drip systems and planter zones can be checked monthly, since established desert plants are more forgiving. Doing this now, before the real heat sets in, means small issues get caught while they’re still cheap and easy to fix.
How to Check Your Sprinkler System
Start at the timer, usually mounted in the garage or on an exterior wall of the house. Turn on each valve or station one at a time and walk the zone while it runs. You’re looking for heads that don’t pop up all the way, weak or uneven spray, visible pooling, or a zone that doesn’t turn on at all.
If a station doesn’t activate, or comes on at a noticeably lower pressure than the others, that’s usually a sign of a failing valve or a break somewhere in the line. Catching that from the timer, before you’re standing in a dead patch of lawn, is what separates a five-minute fix from a full-line repair.
What Happens If You Skip This
Watching your sprinklers and paying attention to plant stress solves most irrigation problems before they start. Skip it, and the yard tells on itself, browning grass, wilting shrubs, and a water bill that climbs while your landscape looks worse, not better. A few minutes of checking each zone now is a lot cheaper than replacing a lawn or reworking a drip line repair later in the summer.

If you’d rather not crawl your own yard station by station, Cacti Landscapes will do it for you. For a flat $80, we evaluate the entire yard, not just the sprinklers, so you know exactly what’s working, what’s failing, and what needs attention before the heat hits. We’re a licensed Nevada contractor (License #84942) and an SNWA Water Smart Contractor, serving both Las Vegas and Henderson, and this evaluation is the same process we run for every landscape maintenance client we service on a regular basis.

FAQs
How often should I check my sprinklers in Las Vegas?
Check grass and sprinkler zones weekly during the hot months, April through October. Drip systems and planter zones only need a monthly check, since desert plants tolerate more variation.
Why do sprinkler systems fail so often in Las Vegas?
Most failures trace back to installation, not equipment age. Thin pipe, undersized pop-up heads, and missing swing joints are common shortcuts that eventually cause breaks, stuck valves, or uneven coverage.
How many plants can one drip station support?
A properly installed drip system with low-pressure emitters can support hundreds of plants on a single station, since every plant receives even water pressure regardless of its position on the line.
