Most Plano systems were buried shallow in the 1990s and 2000s, right when builders cut corners. Winter freezes split PVC, summer heat bakes the soil, and Collin County water restrictions mean you can't just keep running the system longer. Catch it early.

Why Plano Sprinkler Systems Fail So Fast
Black clay under neighborhoods like Craig Ranch and central Plano swells when it rains and shrinks in drought. That movement cracks PVC pipes buried just 6 to 8 inches down—shallow by design because builders saved money. Homes built 1995–2015 in ZIPs 75023, 75024, and 75075 are hit hardest; newer Craig Ranch tracts (75069, 75070) and Stonebridge (75071, 75072) have slightly better systems, but they're not immune.
Then comes June through September. Temperatures stay above 100°F for weeks, baking the soil hard and putting pressure on every joint. A pinhole leak hidden underground can double your water bill in two months before you even see wet grass. Winter freezes crack backflow preventers and valve bodies. Collin County water restrictions mean you're rationed anyway—a leak is pure waste with no upside.
What to Do First: Spot the Signs
Check your water bill. A sudden jump of 20–30 percent with no change in your routine points straight to a leak.
Walk your yard after the system runs. Look for soft spots, moss, or greener patches that don't match the rest of your lawn. Underground leaks push water up through the soil in weak spots.
Listen for hissing near valve boxes or at the backflow preventer after the system shuts off. That sound means water is still running where it shouldn't.
Don't dig or assume you know where it is. A local specialist has detection equipment that pinpoints the break without tearing up your yard. They can also check if the leak is in the mainline, a lateral branch, or at a valve body—each repair is different.

What Happens When You Call a Local Pro
The specialist will ask when your bill jumped and where you've noticed soft ground or odd patches. They'll run your system and listen for leaks.
Then they'll use a combination of electronic detection (some use ground microphones or tracer wire scanners) to narrow down the break to a section of pipe—sometimes to a few feet. They mark it clearly so you know exactly what's wrong before any digging starts.
They'll explain whether it's a mainline (feeds the whole zone), a lateral (branch to one area), or a valve leak. Mainline breaks take longer and cost more; valve leaks are often the quickest fix. A pro in Plano knows clay soil moves things around, so they may recommend reinforcing the repair or adjusting the burial depth slightly when they excavate.
Choosing a Pro in Plano
Look for someone who serves your ZIP (75023, 75024, 75025, 75074, 75075, 75086, 75093, 75094) and knows North Texas clay and heat. They should have detection gear, not just guesswork.
Ask if they handle both the detection and repair—backflow preventer leaks, valve leaks, and PVC breaks—so you're not juggling two companies.
Mention your neighborhood or the age of your home. A pro who's worked Craig Ranch systems and older central-Plano setups understands the specific weaknesses. They can tell you whether your system is worth repairing or if rebuilding a section makes sense long-term.
