What's included
Most sprinkler problems fall into a handful of categories: a zone that won't turn on (usually a valve or wiring issue), heads that don't pop up or spray unevenly (clogged with fine desert dust and sand, broken, or sunk below grade), a soggy spot that won't drain (a broken lateral line), or a controller that's just wrong for the season.
The one weather-related failure worth watching for here is a cracked backflow preventer after one of the valley's occasional hard-freeze nights in December or January — it sits above grade year-round, so it's the one component actually exposed to cold. If water was left in it on a freeze night, it often doesn't show until you notice a leak or lost pressure afterward.
We diagnose by testing zones, checking static pressure, and locating the actual break — not just replacing parts until something works. We repair systems we didn't originally install just as often as our own.
How it works
Step by step, here's what actually happens on site:
- 1Test each zone and check static water pressure to isolate the problem
- 2Locate the specific break — valve, wiring, head, or lateral line
- 3Repair or replace the failed component
- 4Pressure-test the fix before closing anything back up
- 5Re-zone or re-time the controller if the repair changes how a zone runs
Why Mountain Green
We diagnose the actual failure point first instead of guessing — most 'the sprinklers are broken' calls turn out to be one bad valve or one cracked fitting, not a system that needs replacing.
We service systems regardless of who installed them originally.
After any hard-freeze night, we'll check whether the backflow preventer took damage — it's the one component actually exposed to winter cold here.

Sprinkler repair FAQ
A zone stopped working after a cold night — what happened?
Check the backflow preventer first — it sits above grade year-round, so it's the one component actually exposed to Las Vegas's occasional freezing nights. If water was left in it, it can crack and not show until you notice a leak or lost pressure.
Do you repair systems you didn't originally install?
Yes — most of our repair calls are on systems another company installed.
How fast can you get someone out for a broken sprinkler line flooding my yard?
Call and we'll get you scheduled as quickly as we can — for an active leak, shutting off the system's main valve in the meantime prevents further water loss.
Is backflow preventer repair required, or optional?
Nevada plumbing code requires a functioning backflow preventer on irrigation systems — it's not optional, and we can repair or replace one that's failed or freeze-damaged.
