Why Is My Water Bill Suddenly So High? (It's Probably Your Sprinklers)
If your bill jumped and nothing in the house changed, the yard is the first place to look. Here's how to find out — in about five minutes.

You open the water bill and it's double what it should be. Nothing changed inside — same showers, same laundry. Around Katy, when that happens in spring or summer, the culprit is almost always the irrigation system. It runs outside, often before dawn, and a problem can waste water for weeks before you ever notice a wet spot.
The five-minute test that finds it
Before anything else, confirm it's the irrigation and not the house. Turn off every water fixture inside and make sure no irrigation zone is running, then go look at your water meter. Most meters have a small triangular or star-shaped flow indicator that spins when water is moving. If everything is off and it's still spinning, water is running somewhere — and with the house shut down, it's almost certainly the irrigation main line. That single check tells you most of what you need to know.

The usual suspects
- A hidden main-line leak. The main line is pressurized 24/7, so a leak there runs around the clock — the single biggest bill-spiker. From $195 to repair, depending on depth.
- A valve stuck open. If a valve doesn't close all the way, that zone keeps dribbling long after the cycle ends. A worn diaphragm or grit is usually the cause — $125 to $215 to fix.
- Broken or missing heads. A snapped head gushes far more water than a working one, and a missing head is an open pipe. Cheap to fix ($25–$40) but expensive to ignore.
- An over-watering schedule. Sometimes there's no leak at all — the controller is just running too long, too often. Katy lawns need far less water than most schedules deliver (more on that in our watering guide).
How much a leak actually costs you
A main-line leak doesn't look dramatic — often just soft, soggy ground — but running 24 hours a day through a hot Katy summer, it adds up fast. The math almost always favors fixing it quickly: a leak repair from $195 pays for itself against a couple of inflated bills, and the wasted water stops immediately.
How to keep it from happening again
Two things prevent most surprise bills. First, a once-a-year system evaluation ($75) catches a stuck valve or a weeping line before it becomes a summer-long leak. Second, a smart Wi-Fi controller waters based on the weather and skips cycles when it rains — which, in our unpredictable Gulf Coast weather, cuts a surprising amount of wasted watering. If your bill already jumped, though, start with the meter test above and get the leak found.
