Backflow Prevention Las Cruces | Certified Testing & Plumbing Experts
Hi, I’m Gustavo—owner of A to Z Plumbing Heating and Cooling here in Las Cruces.
We do a lot more than fix leaks and ACs. We handle backflow testing and prevention too. And trust me—if you’ve got a sprinkler system, pool, or even just an old hose setup, your water might not be as clean as you think.
We’ve tested and installed backflow preventers all over Las Cruces—from older homes in Mesilla and Doña Ana to businesses off Valley Drive and new builds in Sonoma Ranch. We’ve caught irrigation water, rust, and even fertilizer flowing back into the main line. Most folks had no idea until we showed them.
Keeping your water clean isn’t fancy. But it matters. Especially when it’s the same water your family drinks.

What Is Backflow Prevention?
Backflow prevention is a simple idea. You don’t want dirty water going where clean water is. We use a device called a backflow preventer. It stops the flow when the pressure changes.
Your city water is supposed to push one way—from the street into your house. But if something messes with the pressure (like a water main break or a big fire hydrant use), water can start to move the wrong way. And if your sprinkler or hose is touching something dirty, that junk can get pulled into your home’s water. Bad news.
Who Needs It?
- Homes with irrigation or sprinkler systems
- Restaurants and coffee shops
- Apartment complexes
- Auto repair shops
- Medical offices
We’ve Seen Some Things
I remember this little diner on Main Street. Their soda machine had a connection that wasn’t up to code. One backflow event, and they had to shut down for two days. The owner was nearly in tears. Not because of the plumbing bill—but because she lost a weekend’s worth of sales.
That’s the real cost of ignoring backflow.
Another time, a homeowner in Sonoma Ranch couldn’t figure out why their water was yellow. Turned out their garden hose was sitting in a puddle of fertilizer, and pressure dipped overnight. Boom—garden gunk in the tap.

Backflow prevention isn’t fancy. But it’s smart. And in a place like Las Cruces, where water matters more than most places, it’s worth taking care of.
Let us help keep your water clean. You’ll barely notice the work—but you’ll sure notice if it goes wrong.
"Water's clean until it isn't."
I heard that from a homeowner off Missouri Ave who had just dealt with a backflow mess. Their irrigation system sent dirty water back into their kitchen tap. Coffee tasted like rust. No kidding. The whole thing was a wake-up call—backflow isn’t just about plumbing. It’s about health.
Backflow happens when water flows the wrong way. Like when pressure drops and dirty water sneaks into clean lines. Think lawn chemicals, toilet water, stuff from the street. Nasty.
In Las Cruces, with all the dust, desert plants, and irrigation setups, it’s common. And fixing it early is a lot cheaper than dealing with contaminated water.
Backflow Problems? Yep, Even in Las Cruces.
You’d think it wouldn’t happen here—but it does. We’ve seen backflow issues pop up in homes and businesses all over Las Cruces. It usually shows up:
When irrigation systems don’t have proper backflow preventers
After sudden drops in water pressure (like during hydrant use or line breaks)
In older homes without updated plumbing codes
Around hose bibs and outdoor faucets with no anti-siphon valve
That’s why we always recommend installing and testing backflow preventers—especially if you’ve got a sprinkler system, pool, or commercial setup. It’s an easy fix that keeps dirty water from sneaking into your clean supply.

Backflow Questions We Actually Hear in Las Cruces
Do I really need a backflow preventer in Las Cruces?
Yes — especially if you have a sprinkler system, pool, or use a hose with a sprayer. We’ve seen water from irrigation lines, fertilizer tanks, and garden hoses siphon back into clean water lines. It’s not common, but when it happens, it’s nasty.
How often should I get my backflow preventer tested in Las Cruces?
State law requires yearly testing for most commercial properties, but even for homeowners, we suggest testing once a year — especially in areas with older plumbing like Mesilla Park or University Park. It’s quick and could save you a big headache.
What neighborhoods around Las Cruces see more backflow issues?
Older parts of town like Alameda-Depot, Mesilla, and parts of Elks often have older plumbing without updated backflow protection. We’ve also seen issues pop up in fast-growing areas like Sonoma Ranch where irrigation setups were rushed or DIY’d.
Can backflow actually make me sick?
Unfortunately, yes. Backflow can pull in fertilizer, pesticides, or bacteria from sprinkler lines, pools, or even toilets if there’s a pressure drop. We had one call from a business near Valley Drive where a broken valve led to nasty water pouring out of office taps.
Is this something the city takes care of?
Not usually. Backflow prevention is the property owner’s responsibility. The city may require annual test reports for certain businesses or multi-family homes, but you have to handle the install, maintenance, and paperwork.
We’re Not Some Out-of-Town Company.
We don’t send strangers from El Paso or Albuquerque. When you call us, you’re talking to someone who knows Las Cruces — because we live here too.
We’ve tested backflow preventers in restaurants on Main Street. Swapped out valves in backyards near Sonoma Ranch. Filled out city reports for small businesses over on El Paseo.
We care about keeping the water safe here… because our families drink it too.
