Fort Lauderdale's aquifer water
The City of Fort Lauderdale pumps its water from the Biscayne aquifer, the shallow limestone layer that lies just beneath most of southeast Florida. Wellfields feed two treatment plants. The Fiveash plant, the older and larger of the two, uses lime softening, while the Peele-Dixie plant uses membrane treatment. Together they serve the city and several neighboring communities on contract.
Raw water from the limestone is naturally hard, and treatment removes a good share of that hardness without making it fully soft. A tank on city water collects a pale, sandy layer of calcium over several years, which can be heard as popping when the burner or element heats. Tankless units need regular descaling to stay efficient.
Because Fort Lauderdale's supply sits close to sea level, saltwater intrusion into the aquifer is a long-term concern for the utility. That has no direct effect on today's tap water, but it is one reason the city and Broward County watch their wellfields closely.
Canal homes, condos and older ranches
The Las Olas Isles, Rio Vista, Harbor Beach and Coral Ridge neighborhoods are lined with waterfront homes, many built in the 1950s and 1960s as single-story ranches and later expanded or replaced with two-story houses. Heaters in those homes typically stand in the garage or a utility room facing the canal side, where salt air reaches them easily.
Victoria Park, Sailboat Bend, Tarpon River and Colee Hammock have older cottages and small homes, sometimes with heaters in exterior closets accessed from the side yard. Imperial Point and Bermuda Riviera further north have mid-century ranches with garage installations, while the high-rise condos along A1A and downtown use small electric tanks in unit closets or central systems maintained by the building.
Since Florida homes are built on slabs, there are no basements, and heaters are generally installed at or near ground level. That matters a great deal in a city where some streets flood several times a year.
King tides, storms and salt
Each fall, the highest tides of the year push canal water over seawalls and up through storm drains in low parts of the city, including sections of Las Olas Isles and Rio Vista. Garages in these areas sometimes take on a few inches of salt water, which can ruin an electric heater's lower element housing or a gas burner sitting on the floor.
Hurricanes add their own risk. Wilma in 2005 and Irma in 2017 both brought long power outages to Broward County, and a few low neighborhoods saw storm surge. In April 2023, a rainstorm that dropped more than two feet of rain in a single day flooded homes and garages across Fort Lauderdale. A heater that stood in that water needs a licensed plumber's look before anyone powers it back up.
Even without flooding, salt air near the ocean and the Intracoastal attacks steel jackets, brass valves and electrical connections. Rust stains near the base of a heater in a canal-side garage are common long before a tank actually leaks.
The problems plumbers see most in Fort Lauderdale
- Corroded tank bottoms on garage heaters exposed to salt air for years.
- Burned-out lower elements after calcium settles over them.
- Flood-damaged controls after king tides or heavy storms reach the garage floor.
- Leaking relief valves that drip from heat and pressure.
- Condo closet heaters leaking into the unit below.
- Failed thermostats on electric heaters that are 10 years old or more.

| Job | Typical Fort Lauderdale range | Notes |
|---|---|---|
| Electric element and thermostat | $150–$350 | |
| Relief valve replacement | $150–$300 | |
| Gas control valve | $400–$625 | Gas homes are less common |

South Florida plumbing labor is costly, and Fort Lauderdale condo jobs often add building scheduling, elevator reservations and insurance paperwork. Flood-elevation requirements on canal homes can also add cost when a heater needs to be raised during replacement.
Licensing and permits in Fort Lauderdale
In Florida, the DBPR's construction licensing board certifies plumbing contractors statewide, and some contractors work under a county-level registration instead. Either kind of license can be looked up on the DBPR site in a few seconds.
Fort Lauderdale's building services office issues permits for water heater replacements, and an inspector looks at the relief valve line, strapping, electrical or gas connections and the pan. Condo associations often have their own rules, requiring the contractor to show insurance and sometimes a specific type of pan or leak shutoff. Neighboring Broward cities such as Wilton Manors and Oakland Park run separate permit offices.
Electric heaters and FPL
Florida Power & Light supplies electricity across Fort Lauderdale, and most homes here heat water with electricity. Natural gas from Peoples Gas reaches some neighborhoods, and propane is used in a few larger waterfront homes for tankless units and pool heaters.
A heat pump tank thrives in Fort Lauderdale's warmth, especially in a garage, where they also take some humidity out of the air. FPL has had efficiency programs at times, and it is worth asking what is available. Solar water heating, once common in South Florida, still turns up on older roofs, and plumbers sometimes service the storage tanks tied to those systems.
Protecting a heater near the water
If your garage has flooded during a king tide or a storm, raising the heater onto a platform during replacement is often the simplest protection. A plumber can also install an automatic leak shutoff valve, which closes the cold supply if the pan sensor gets wet. That is especially useful for condos and for homes where the heater is in an interior closet.
Wipe salt film off the heater jacket and valves a few times a year, and look for rust around the base and the relief valve. Catching corrosion early often buys time to plan a replacement instead of reacting to a sudden leak.
Repair or replace in Fort Lauderdale
Salt air and aquifer calcium shorten tank life here, and many heaters in canal-side garages last eight to ten years. Element or thermostat failures on a younger heater are worth repairing. A leaking tank, extensive rust on the base, or a unit that spent time submerged belongs on the curb. Condo owners should plan replacement before a tank reaches the end of its warranty, since leaks into a unit below can lead to costly claims.
Around Fort Lauderdale
Wilton Manors and Oakland Park border the city to the north and have their own building offices. Lauderdale-by-the-Sea sits right on the beach with similar salt exposure. Plantation and Davie to the west have their own utilities, and Dania Beach and Hollywood to the south handle permitting separately.
Water heater questions from Fort Lauderdale
Why is my Fort Lauderdale water heater rusting on the outside?
Salt air from the ocean and canals corrodes steel jackets and fittings. Rust near the base can mean the tank is close to leaking.
My garage took on water during a king tide. Is my heater safe?
Have it inspected. Salt water reaching the burner, elements or wiring can cause failures and safety issues.
Will Fort Lauderdale building services need to sign off on my swap?
Yes. The city's building services office issues the permit, and an inspection follows.
Where does Fort Lauderdale get its water?
From wells in the Biscayne aquifer, treated at the Fiveash and Peele-Dixie plants.
Does a heat pump unit pay off in a Fort Lauderdale garage?
Often, yes. The warm climate keeps them efficient, and FPL has offered incentives at times.
My condo heater leaked into the unit below. What now?
Shut off the water to the heater, call a plumber, notify your association, and contact your insurer with photos of the damage.
