After a Water Main Break in Lake Mary: Emergency Plumber Help and What to Do Once the Boil Notice Lifts
A main break on a Friday afternoon can leave hundreds of homes without water, and it often leaves questions about the pipes inside. Call Oviedo FL Expert Plumbers with your address and what you have noticed at the taps, and we will tell you whether we can help at your location. This page covers the house-side checks after an outage or a boil notice.
When the street goes dry: what a Lake Mary main break looks like
On August 15, 2025, a water main break on S International Parkway near Lake Mary Boulevard and Interstate 4 left over 500 addresses without water, according to a local television news report. The report described a precautionary boil water notice for the affected addresses and directed residents to Seminole County Utilities at 407-665-2110, available weekdays during business hours.
That event shows how an outage reaches a house. The break is in the street, the notice comes from the utility, and your part is the house side. Our part starts after the water returns, when pressure, air in the lines and sediment can cause problems you did not have before.
| What you notice | Likely side | Who to call |
|---|---|---|
| No water to the whole street | Street side | The utility named on your bill |
| Water at a few taps but not others | House side | A plumber |
| Spitting faucets or cloudy water when service returns | Air or sediment in the lines | Run the taps; call us if it persists |
| Wet ground near the meter | Meter or street side | The utility first |
Water back on after a boil notice: a checklist for the house
Wait for the utility to lift the notice before relying on tap water. Then work through the house, because a few appliances and fittings keep a record of the outage.
- Open the cold taps one at a time, starting at the lowest point in the house, and let them run until the water is clear.
- Open the hot taps and run them the same way.
- Flush toilets and run the washer empty for a cycle.
- Follow the manufacturer's guidance for the ice maker, filters and any water treatment unit.
- Check under sinks and around the water heater for new drips.
Air in the lines can cause banging or spitting. It usually clears on its own. Pipes that bang at every use after the water returns should be looked at, and the pressure regulator, if there is one, may need a check.
- Do not use water you think is contaminated for drinking until the utility says it is safe.
- Replace filter cartridges if the manufacturer says to after an event like this.
- Keep the date and time the notice started and ended.
The street side, the meter and the house: where the utility stops
The utility owns the main and usually the meter. The pipe from the meter to the house is generally the homeowner's. We could not confirm a rule specific to Lake Mary, so ask the utility named on your bill where its responsibility ends at your address.
The meter test shows whether water is moving through the house with everything off. If it is, the leak is on your side of the meter or at it. See the meter test for finding a hidden leak for the steps, and call the utility if the meter itself looks damaged.
A water heater after an outage: what to check before relighting
A water heater that runs while the supply is off can overheat or draw air into the tank. After service returns, make sure the tank is full before it turns on. An electric heater with a dry tank can burn out its elements.
- Open a hot tap at the highest point in the house and let water run until it flows steadily.
- Only then switch an electric heater back on or relight a gas heater according to its label.
- Look for new drips at the relief valve and the fittings.
- Call us if the heater makes new noises or the water runs hot and cold.
If something looks wrong, the checks in diagnosing a heater that misbehaves after an outage are a good starting point.
Spitting faucets, banging pipes and air after the water returns
When service returns after a break, air is trapped in the pipes and comes out as spitting or sputtering. It usually clears after a few minutes with the taps open. A hammering sound when a valve closes is a different problem, and it may mean a loose pipe or a changed pressure.
- Open the taps wide, one at a time, and let them run until the flow is steady.
- Listen for banging when you close a tap or when the washer fills.
- Check for new drips at the washer hoses and under sinks.
- Call us if banging or low pressure continues after a day.
A pipe that bangs every time a valve closes may need securing, and a worn valve may be the cause. A plumber can find which.
Lake Mary outage preparation: shutoff, meter photo, utility number
A main break can leave a street dry for hours. A few preparations make the next one easier, and none of them cost much.
- Find the main shutoff and mark it so anyone in the house can find it.
- Photograph your meter on a quiet day so you have a baseline.
- Keep the utility's phone number from your bill where you can find it.
- Store a few days of drinking water if you want a margin.
- Know where the water heater shutoff and the irrigation shutoff are.
None of this prevents a main break. It lets you tell a street problem from a house problem quickly, which is what our first question will be.
