An automated call from Gainesville Regional Utilities saying your meter shows a possible leak is easy to dismiss. It should not be. GRU’s smart meters flag continuous water use, and continuous use in a house usually means water is going somewhere it should not: into an irrigation zone, down a running toilet, or into a wall, a slab or a cabinet base where nobody sees it yet. This guide covers what the alert actually means, how to confirm it at the meter, who is responsible for which part of the pipe, how GRU’s leak adjustment works, and when the leak has become a water damage problem rather than a billing one.
What the GRU leak alert means, and what it does not
According to GRU’s Water Leak Detections & Notifications page, the utility reviews smart meter data for unusual patterns, usually continuous use or a sudden, significant increase, and contacts residential customers with an automated phone call when a leak is suspected. The same page is careful about the limits:
- the alert means you may have a leak, not that you definitely do;
- GRU cannot tell you where the leak is;
- if the pattern continues, GRU may call again;
- water that passes through the meter is billable whether it was used or lost.
GRU lists the common culprits as a running toilet, a leaking flapper valve, a dripping faucet, a water softener malfunction, and irrigation system damage or stuck valves. Those are mostly nuisances. The ones that damage a house are the ones you cannot see: a supply line behind a vanity, a pipe under a slab, a water heater connection in a closet.
Confirm it at the meter in about 15 minutes
GRU’s notification page describes a simple meter check:
- Turn off all water inside and outside the home, including irrigation.
- Wait 10 to 15 minutes.
- Look at the leak indicator on the meter. If it keeps moving, there is a leak on your property.
GRU’s Leak Detection page adds that its meters read to tenths of a gallon, and gives its own example: movement of one-tenth of a gallon every five minutes works out to 868 gallons a month. For toilets, GRU suggests a dye test: a few drops of food coloring in the tank, no flushing, and a check of the bowl after about 30 minutes. The U.S. EPA’s WaterSense Fix a Leak Week materials describe the same dye method.
If the indicator moves with every fixture and the irrigation off, the next question is whether the water is leaving the house through a drain or staying in the structure.
Who is responsible for which section of pipe
GRU publishes the split on its Responsibility for Damaged Utilities page:
| Service | GRU’s responsibility | Customer’s responsibility |
|---|---|---|
| Water | Everything from the main service outlet up to the water meter | The pipe running from the water meter to the house |
| Wastewater | Damage to lines outside the property line | Repairs within the property line |
The leak notification page says the same thing in plainer terms: GRU maintains utility-owned lines and equipment up to the meter, and it does not fix leaks in your home. If water is bubbling up at the meter box or in the street, call GRU at 352-334-3434. If the meter check points to the house side, the repair is yours to arrange, and GRU’s own recommendation is to call a licensed plumber.
Florida licenses plumbing contractors through the Department of Business and Professional Regulation. Before hiring, you can look up a contractor’s license on the state’s DBPR license search.
When a leak alert becomes a water damage problem
A meter alert only tells you water is moving. These signs tell you it is staying in the house:
- stained or warm spots in flooring, or tile that sounds hollow;
- baseboards swelling, or paint bubbling low on a wall;
- a musty smell in a closet or under a sink cabinet;
- carpet that is damp with no spill to explain it;
- outside, a patch of grass that stays greener or soggier than the rest, which GRU lists as a warning sign.
Florida homes add one complication: high indoor humidity and air conditioning condensate can produce damp spots that are not plumbing at all. Our guide to telling condensation from a leak walks through how to separate the two before anything is opened up.
Timing matters once materials are wet. The EPA’s Brief Guide to Mold, Moisture and Your Home advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. A slow leak that has run for weeks has usually passed that window, which is why the repair and the drying are two separate jobs: the plumber stops the water, and drying the cavity, subfloor or cabinet base is what keeps the damage from spreading. Our page on what drying equipment actually does explains why fans alone rarely reach wet materials inside walls.
The GRU leak adjustment: what to keep
GRU’s Leak Detection page says that, under limited situations, it may adjust the rate charged for water and/or sewer for a billing period in which you had a leak at your service address. The request goes through GRU’s leak adjustment form and, according to GRU, must be made within 90 days of the billing period in question, with:
- the type of leak;
- the date the leak started;
- the repair date;
- proof of repair, such as a plumber’s statement or a receipt for repair supplies.
Two practical points follow. Keep the date of GRU’s alert call, since it helps establish when the leak started. And keep the plumber’s paperwork even if the water damage cleanup is handled by someone else: it is the document GRU asks for. The adjustment is GRU’s decision, and the page does not promise an outcome.
A short order of operations
- Do the meter check with everything off.
- If the indicator moves, close the main shut-off at the house and check the obvious fixtures and irrigation.
- Look for signs of water in the structure, room by room, and photograph what you find.
- Call a plumber for the repair on the house side of the meter; call GRU if the leak is at the meter or beyond it.
- If materials are wet, plan the drying the same day. Our checklist for the first 60 minutes of water damage covers what to do before anyone arrives.
- File the leak adjustment request within GRU’s 90-day window, with proof of repair.
Frequently asked questions
GRU called about a leak, but I can’t find one. What now?
Run the meter test with all water off. If the indicator does not move, the alert may have reflected a period of continuous use, such as irrigation. If it does move, the leak is on your property, and the absence of visible water often means it is inside a wall, under a slab or underground between the meter and the house.
Does GRU repair leaks on my side of the meter?
No. GRU says it maintains utility-owned lines and equipment up to the meter and does not fix leaks in your home. The pipe from the meter to the house is the customer’s responsibility.
Is the sewer line in my yard my responsibility?
Per GRU’s responsibility table, wastewater repairs within the property line are the customer’s; damage to lines outside the property line is GRU’s.
