Why Is My Water Bill So High? Common Sprinkler Causes
If your JEA bill jumped this month and nothing else changed in your house, the sprinkler system is almost always where to look first. We've diagnosed thousands of these in Jacksonville — and 95% of the time, the culprit is one of four things.
1. A Stuck or Leaking Valve
Sprinkler valves open to start a zone and close to stop it. When a valve sticks open — usually from worn diaphragm rubber or a piece of debris — that zone keeps running. Sometimes it's obvious (a section of lawn that's constantly wet), and sometimes the valve is partially open enough that water trickles 24/7 without any visible puddle. Either way, the meter keeps spinning.
How to spot it: Walk every valve box. Any soggy ground near a valve, or any zone that's noticeably greener than the rest, is your tell.
2. A Broken Underground Pipe
PVC and poly pipe crack. Tree roots invade. Tree removal contractors hit lines. Freeze cycles split pipe at the joints. When this happens, every time the system runs, water pours into the ground at the break instead of out through the heads — and the affected zone loses pressure on the heads farther down the line.
How to spot it: A zone where some heads barely pop up while others run normally, plus a soft, soggy patch in the lawn somewhere along that zone's path.
3. A Missing or Broken Sprinkler Head
This is the dramatic one — a head that's been broken off (often by a mower) turns into a fountain when the zone runs. A 1" pipe with no head on it dumps an astonishing amount of water in 15 minutes. Three weeks of that and your bill doubles.
How to spot it: Run each zone manually and walk the yard. Look for geysers, missing heads, or heads spraying way past the lawn.
4. A Failed Rain Sensor or Bad Schedule
Sometimes there's no leak at all — the system is just running too often or for too long. Common reasons:
- The rain sensor failed and is no longer skipping cycles after Florida thunderstorms.
- Someone "borrowed" extra runtime during a dry stretch and never turned it back down.
- The controller battery died, defaulted back to the factory schedule, and the system is now running every zone every day.
How to spot it: Open your controller and look at the program. If every zone is set to run every day, that's almost certainly the problem.
How to Run a Quick At-Home Check
- Turn off all water inside the house.
- Find your water meter and watch the leak indicator (the small triangle or gear).
- If it's spinning, you have a leak somewhere — and if the sprinkler isn't running, the leak is in a valve or pipe.
- Shut off the main sprinkler valve. If the meter stops spinning, the leak is in the irrigation system.
One stuck valve can add $200+ per month to a Jacksonville water bill. Almost every "my bill is crazy high" call we run ends with a single, fixable problem.
