Villages Sprinkler Repair Water bill spike or hidden leak: what's wrong and what it costs
A water bill that jumped with no obvious wet spot in the yard is one of the more common ways a hidden leak actually gets discovered, since a lateral or mainline break underground doesn’t always surface visibly, especially in Florida’s sandy soil. The other common cause is a valve that isn’t fully closing, leaking continuously even when the system should be off. Diagnosis is included in the $75 to $150 service call; fixes run $100 to $600 depending on what’s found.
Check this first (before calling)
- Isolate your irrigation system at its shutoff for a day if you can, and compare your water usage with it off versus a normal day with it running its schedule. A big drop with the system off points squarely at irrigation, not indoor plumbing.
- Check every valve box for standing water between scheduled cycles, a sign a valve is leaking continuously rather than just during its run time.
- Walk the yard looking for any soft, spongy, or unusually green patch, even a small one away from any head, which can indicate an underground leak that hasn’t fully surfaced.
- Listen at the valve boxes and near buried lines for hissing, particularly right after the system has run and pressure is still up.
What’s usually wrong
| What you notice | Likely cause | Fix and cost |
|---|---|---|
| Valve box stays full of water between cycles | Valve not fully closing, leaking continuously | Valve repair, $150 to $350; see valve box full of water |
| Soft or soggy patch away from any head | Lateral line leak underground | Lateral line repair, $100 to $300 |
| No visible wet spot at all, bill still spiked | Leak below grade in sandy soil, or a mainline issue | Line repair, $100 to $600 depending on location |
| Usage normal with irrigation shut off, spike continues | Not the irrigation system; check indoor plumbing | Outside irrigation scope |

Why this happens here
Florida’s sandy soil is part of the reason a leak here can run longer before anyone notices it than in a place with denser clay soil: water spreads out and drains below grade more readily instead of pooling visibly at the surface. A meaningful share of Villages-area homes also water on a non-potable system rather than the metered potable supply, which changes the bill-spike math (a non-potable irrigation leak may show up as a spike on a separate irrigation utility charge rather than the main water bill, depending on your district’s billing structure), so check the specific line item that jumped, not just your total bill.
When to call
Reasonably soon, not a same-day emergency unless you’ve also found active pooling somewhere. A leak that’s been running for weeks before showing up on a bill is unlikely to become a true emergency overnight, but every additional billing cycle it runs costs real money, so it’s worth scheduling within a few days of noticing the spike.
Related problems
If you’ve already narrowed it to a specific valve box staying full, go straight to valve box full of water. If the spike came with a zone that clearly won’t shut off, see zone won’t shut off instead, since that’s a more obvious version of the same underlying issue.

Frequently Asked Questions
How do I know if the spike is my irrigation system versus my house?
If you can isolate your irrigation system at its own shutoff and your indoor usage still shows normal for a day with the system off, the irrigation side is cleared and the leak is elsewhere. If usage drops significantly with the system shut off, the irrigation side is the culprit.
Why wouldn't I see any wet spot with an underground leak?
Florida's sandy soil lets water spread out and drain below grade more than denser soil types, so a leak can run for a while before it ever surfaces visibly, especially a smaller leak on a lateral line rather than a full mainline break.
Is a slow valve leak enough to cause a real bill spike?
Yes. A valve that's weeping continuously, even a small amount, adds up over a full billing cycle, especially since it's leaking around the clock rather than only during scheduled watering windows.
