FAILURE MODE 01
The Valve Class Was Wrong
Valves are the moving parts of an irrigation system — the components that open and close every time a zone runs. They also fail before anything else. There's a massive quality gap between a commercial-grade Hunter/Rain Bird/Irritrol valve ($35–$55 each) and a bargain-bin plastic valve ($12–$18 each). The cheap ones crack, leak, or fail in 2–4 years. The good ones last 15–20 years.
Multiply that by 8 valves in a typical system and you have real money — either saved upfront and paid back in repairs, or spent upfront and forgotten about for a decade.
What it costs you: A cheap valve failing in year 3 runs $120–$180 to replace, times several over the system's life. Easily $1,000+ over 10 years.
FAILURE MODE 02
The Zones Weren't Hydraulically Designed
Every zone on a sprinkler system has a water budget — the maximum flow (GPM) and pressure (PSI) available from the water supply. Cram too many heads onto a single zone and the pressure drops, spray patterns collapse, coverage fails, and the whole zone is effectively useless from day one. The math isn't hard, but it does require actually measuring the water supply, knowing the flow rate of every head type, and calculating zone capacity before installation.
A lot of installers skip this calculation and just "eyeball it" — which is why so many systems have chronic coverage problems that no amount of repair visits will fix. It was wrong from the start.
What it costs you: Chronic dry spots, dead turf, and "we've tried everything" — you can't fix hydraulics with repairs. Whole-zone reinstallation is the only solution.
FAILURE MODE 03
The Backflow Preventer Was Plastic, Not Brass
The backflow preventer is the device that keeps sprinkler water from flowing backward into your house's drinking water supply. It's required by Texas law, and it takes a beating — sitting outside, exposed to freeze, heat, and UV for decades. There are two kinds: brass (the industry standard, lasts 20+ years) and plastic (cheaper upfront, fails in 5–8 years from UV and freeze damage).
Cheap installers use plastic. Good installers use brass. A plastic backflow preventer that cracks in a hard freeze will flood your yard, ruin your next water bill, and in rare cases contaminate household water.
What it costs you: A plastic backflow failing in a hard freeze: $400–$900 to replace, plus possible water damage to landscape or house.
FAILURE MODE 04
The Heads Were Wrong for the Zone
There are several fundamentally different kinds of sprinkler heads, and mixing them incorrectly guarantees failure. Spray heads throw water fast and are good for small areas. Rotor heads throw water slowly and evenly over large areas. MP Rotators split the difference. Drip lines water beds and trees directly. Putting spray and rotor on the same zone means one group will overwater while the other underwaters — no matter how long you run it.
A well-designed installation matches head types to the zone and the zone to the landscape feature it's watering. A cheap installation uses whichever heads were on the truck that day.
What it costs you: Runoff, erosion, dead turf, wasted water, impossible programming. Fix = re-design the entire zone.
FAILURE MODE 05
The Pressure Was Never Regulated
Municipal water pressure in North Fort Worth varies from 60 to over 100 PSI depending on the neighborhood, the time of day, and the season. Most sprinkler components are rated for a maximum of 70 PSI. Running a system at 95 PSI causes "misting" — where water atomizes into a fog before it hits the ground, evaporates instantly, and doesn't actually water anything. It also wears out components faster.
The solution is a pressure-reducing valve or pressure-regulated heads. A good installer checks supply pressure before the quote and designs for it. A cheap installer skips this step, and you find out in year 2 when you're watering 45 minutes per zone and the grass still dies.
What it costs you: 20–40% more water usage than necessary, dramatically accelerated component wear, and coverage that gets worse every year.
FAILURE MODE 06
The Permit Was Never Pulled
Most North Fort Worth cities require a plumbing and irrigation permit before a new system is installed. This permit verifies the installer is licensed, the design meets code, the backflow preventer is installed correctly, and the system passes a final inspection before it's used. Skipping the permit is faster and cheaper — and it creates liability at resale, leaves you with no legal recourse if something fails, and guarantees no inspection ever caught the other five failure modes above.
Landon pulls permits. That's not a brag — it's the baseline for legal work in Texas. Ask any installer about their permit record before you sign anything.
What it costs you: At resale: inspector flags it, potential retrofit required. Worst case: water damage claim denied by insurance because the system was unpermitted.
