How Do You Turn Off the Water to a House in Port St. Lucie?
You turn off the water to a Port St. Lucie house at the house valve: the main, or master, shut-off on your side of the water meter. Close it and the supply to the house stops. Which other valves you may touch depends on your water utility, and the sections below cover both the City of Port St. Lucie and the St. Lucie West Services District.
If the valve will not budge, the utility can shut the water off at the meter, and we take emergency plumbing calls across St. Lucie and Martin counties.
Where Is the Valve to Shut Off the Water in a Port St. Lucie Home?
Start outside. Universal Property & Casualty Insurance Company, a Florida home insurer, says that in warmer climates the main shut-off is usually outdoors, where it could be on an exterior wall at the point the main water line enters, perhaps near a hose bib. On a slab-on-grade house, it adds, the valve may be inside instead, near the water heater, under the kitchen sink or elsewhere. In practice, check the wall where the line comes up, then the garage, water heater and kitchen sink.
The Florida Building Code, Residential, 8th Edition (2023), section P2903.9.1, requires an accessible main shutoff valve near the entrance of the water service, plus a valve at the curb or lot line in accordance with local requirements. An older house can predate it.
For St. Lucie West Services District customers, the District's leak page says the valve is usually outside, between its meter and your property, and offers to help you find it.
Which Water Valves Can a Port St. Lucie Homeowner Shut Off Themselves?
Your house valve. On City of Port St. Lucie water, the FAQ on the Utility Systems Department's New Customers page says you may shut off your own water only at the house valve: only authorized City personnel have access to the City's pipes and meters, and any loss or damage to City property is the customer's responsibility.
The City's Utility Customer Service Guide says the meter, in a plastic box in the ground outside your home, is City property like the mains and service lines feeding it, and that all lines and plumbing beyond it are the owner's to maintain and repair. Its 2024 Utility Standards Manual puts a curb stop on every water service at the property line, where the meter goes in, so that valve is the City's too. If the only valve you find is inside the meter box, ask the City before turning it.
The St. Lucie West Services District's leak page draws the line at its meter box too, sending home-side leaks to your HOA property manager or a contractor, handyman or plumber. Not sure which utility serves you? See which utility bills your home.
In Martin County, the county utility's water service line inventory page puts the boundary at the meter as well: the county owns the line through the meter and meter box. We cover homes across Martin County too. Private wells have no utility meter, so none of this applies to them.
How Do You Turn Off a Gate Valve or Ball Valve Without Breaking It?
First the rule. Universal Property's guide says that if a valve is difficult to turn, do not force it; call a plumber or the local public works authority, which here means your water utility. If it moves, the handle tells you how far to turn, and the same guide covers both types:
- Gate valve, round wheel handle: turn it to the right, clockwise. A few turns should stop the wheel.
- Ball valve, lever handle: turn it slowly, clockwise, a quarter turn, until the handle no longer runs parallel to the pipe.
With the valve closed, the water heater comes next, before you drain anything.
What Should You Do About the Water Heater Once the Water Is Shut Off?
Switch an electric water heater off at its breaker before you drain the pipes, and on again only when the tank is full. Gas heaters follow their own manuals.
Universal Property's guide sets the order:
- With the house valve closed, switch off the water heater's power before any water drains.
- Open the tub and sink faucets on the highest floor to relieve the pressure, then others as needed to drain the pipes.
- To restore water, close all but one or two faucets and turn the house valve counterclockwise slowly, slower still on a lever, stopping, Universal says, after half a revolution on a wheel handle or one-eighth of a turn on a lever.
- When the faucet noise settles, open the valve fully and bleed the air by opening each faucet slowly until the noise ends.
- Turn the heater on last. Rheem's use and care manual for its electric residential water heaters with electronic control says the tank must be full before the heater is turned on, and a steady flow from the hot water faucets shows that it is.
Universal also says to keep faucets open in an extended shutoff to prevent pressure build-up, which it says can help against freezing in cold climates. Close all but one or two before the water returns.
Should You Shut Off the Main Valve Before a Hurricane Hits Port St. Lucie?
Not by default: learn it before the storm and close it when something goes wrong. St. Lucie County's Disaster Preparedness Guide tells residents to know how, when and where to shut off the water at the main source of the home, and dates the Atlantic hurricane season from June 1 to November 30.
If you stay on City water, the City's customer service guide says a power outage should have no impact on City water customers, since its treatment facilities run on generator power, and suggests filling containers with tap water before a storm.
Close the house valve when:
- a pipe breaks on the house side of the valve;
- lines may have cracked: Ready.gov, the U.S. Department of Homeland Security's preparedness site, says cracked lines may pollute a home's water supply and suggests shutting off the water until authorities say it is safe to drink;
- you evacuate, the house is damaged and you are instructed to, the two conditions Ready.gov's evacuation page sets for shutting off utilities before leaving.
If you leave the house empty, the seasonal steps below apply.
How Do Seasonal Port St. Lucie Residents Shut Off the House Valve Before Leaving?
Close the house valve on the way out, or ask the City to lock off the meter. Several replies in a widely read r/Home thread describe a toilet supply line bursting while the owners were away.
The City's customer service guide lets seasonal residents and extended travelers request that lock-off, to prevent unauthorized use or damage should a leak occur. The City's FAQ recommends having the water turned off to avoid possible water loss, with no charge for the turn-off and a charge for reconnection, and routine requests are handled the next business day. On St. Lucie West water, close the customer shut-off valve, usually between the District's meter and your property.
Rheem's manual says that if its heater will sit idle for an extended period, the power and water should be turned off, to save energy and prevent a build-up of dangerous hydrogen gas. Other brands' manuals carry their own versions, so check yours. When you come back:
- Refill the system with the breaker still off, as above.
- Before using any electrical appliance connected to the hot water system, open the kitchen hot water faucet for several minutes. Rheem warns that extremely flammable hydrogen can build up in a system unused for a long period, generally two weeks or more, and says not to smoke or use an open flame near the faucet while it is open.
- Rheem also says the heater's operation and controls should be checked by qualified service personnel after a long shutdown, with the tank completely full before it runs.
Who Can Shut Off the Water in Port St. Lucie When the Main Valve Is Stuck?
The utility. On City water, the FAQ leaves the meter side to authorized City personnel, so call the City: its customer service guide lists a phone option for reporting water and sewer emergencies, and its FAQ offers same-day turn-off for an extra charge, paid before the visit is scheduled. On St. Lucie West water, call the District. Its FAQ says that when the District notifies a customer of a leak on the customer's side of the water service line, the customer may request a temporary shutoff while the repair is scheduled, and that if you are not home when service is restored, the District needs a signed waiver on file to turn the water back on.
Once the water is off, the stuck valve is a repair on your side of the meter, and we take urgent plumbing calls. If water was escaping out of sight, leak detection comes next, and our guide to the signs of a hidden water leak covers a meter test you can run once the water is back on.
When Should Port St. Lucie Homeowners Replace a Leaking Shut-Off Valve?
When it will not close all the way or will not turn. Ready.gov's safety skills page says to make sure you can shut the valve off completely; it may be rusted open or may not close all the way, and if so, replace it. A drip at the handle or stem is a leak on your side of the meter, and it needs a repair or a new valve.
Test it before hurricane season opens on June 1, the start date in the county's guide. With the water heater handled as above, close the valve and open a cold faucet. Once the pipes drain, the flow should stop; water that keeps coming means the valve is not sealing. Reopen it with the same steps.
On City water, replacing it starts with asking the City to shut the water off at the meter. On St. Lucie West water, call the District first: its FAQ says you may request a temporary shutoff after the District notifies you of a leak on your side of the line.
A replacement should meet the Florida Building Code section quoted above, P2903.9.1: accessible, near the entrance of the water service, and of a full-open type with a way to drain the line, such as a bleed orifice or a separate drain valve.
The Recap
- The house valve is yours; on City water it is the only one. On St. Lucie West water, it is usually between the District's meter and the property.
- Wheel handle: clockwise until it stops. Lever: slowly, a quarter turn. Do not force a stiff one.
- Electric water heater: off before draining, back on only when the tank is full.
- Test the valve before hurricane season.
- Leaving for the season: close it or have the City lock off the meter. If the hot water system sat unused for a long period, generally two weeks or more, Rheem says to open the kitchen hot water faucet for several minutes before using any electrical appliance connected to it, with no smoking or open flame near the faucet.
- Stuck: call the utility. Not sealing: replace it. Dripping: repair or replace it.
