When a leaking water heater means replacement
Water heater replacement means removing the failed tank and fitting a new one with new connections, a proper relief valve and a safe drain. It is the right call when the steel tank itself leaks. A tank liner that has corroded through cannot be sealed from outside, and a second leak usually follows within days.
If the leak is only at a fitting or valve, a water heater repair may be enough. We check that first so you do not buy a new tank you do not need.
Tank leaking: what to do right now
A tank leak gets worse as the water pressure keeps pushing. Hot water can scald, and standing water near electric wiring is dangerous. Treat any steady flow as an emergency and call the 24/7 line, nights and weekends included.
Steps while the plumber is on the way
If you smell gas, leave the home and call the gas utility or 911 before anything else. Do not turn on lights or appliances on the way out.
- Switch the electric heater off at the breaker, but only if the panel is dry and you can reach it safely.
- Close the cold water shutoff on the line above the tank.
- Open one hot tap to relieve pressure and slow the leak.
- Lift items off the floor and move vehicles away from a garage leak.
- Photograph the tank, label and water damage for your records.
Why tanks fail and what the leak tells us
Inside every tank, the anode rod sacrifices itself to protect the steel. Once the rod is spent, rust attacks the liner and tiny pinholes open near the base or the welds. Many tanks are at the end of their life after around a decade, though use and water conditions change that.
Sediment makes it worse. Minerals settle on the bottom, overheat the steel and crack the glass lining. Rumbling, popping and cloudy hot water are late warnings, and rusty drips at the base are the last one.
Choosing the new unit: gas, electric or hybrid heat pump
| Option | Best fit | Things to check |
|---|---|---|
| Same fuel, same size | Fastest swap, least change | Pan, relief pipe and venting meet current needs |
| Electric tank | Homes without gas service | Breaker size, wire condition, 240-volt circuit |
| Gas tank | Homes with a gas line and flue | Flue draft, gas connector, combustion air |
| Hybrid heat pump | Lower running cost where space allows | Open air around the unit and a condensate drain |
| Switching to tankless | Long-term space and standby savings | Gas line size, venting, electrical load |
A hybrid heat pump unit pulls heat from the air around it, so it needs open space and works best in a larger garage or utility room. A closet with little air flow is usually a poor fit. We will tell you if your room is wrong for it before you buy.
Sizing the new tank
Size follows how your household uses hot water, not the label on the old tank. Count bathrooms, showers that run together and big users such as soaking tubs. A 40-gallon tank often serves a small household, and larger homes tend to need 50 gallons or more.
A tank that is too small runs out mid-shower. One that is too big wastes energy keeping extra water hot. We go over the numbers with you and match the unit to the space.
What the replacement visit involves
- 1
Shut off and drain
We kill power or gas, close the cold supply and drain the old tank through a hose to a safe spot.
- 2
Remove and prepare
The old unit comes out. We inspect the shutoff valve, flexible connectors and drain pan, and replace anything worn.
- 3
Set and connect
The new tank goes on a level base with a new relief valve and discharge pipe. We add an expansion tank when the system calls for one.
- 4
Fill, test, explain
We fill the tank, purge air, light or energize it and check temperature, pressure and every joint. You get shown where the shutoffs and breaker are.
Permits, code and the building department
Most work in Royal Palm Beach requires a building permit, but the Village does not publish a water heater rule of its own. Call the Village building department at (561) 790-5128 before any replacement, and ask what it requires for your address. The Florida Building Code, Plumbing, 8th Edition (2023) is the edition in effect.
Palm Beach County has a like-for-like change-out form, but it applies to unincorporated areas, not the Village. If you live south of Southern Blvd, you may be dealing with Wellington and its own building department instead.
Repair or replace: a quick decision guide
Replace now
- Water leaks from the tank body or base seam
- Rust-colored water and a rusty tank
- The unit is old and the repair bill is high
- Repeated failures in a short time
Repair instead
- A fitting, valve or element is the only fault
- The tank is dry and intact
- A pilot or igniter has simply failed
- The unit is young and well kept
A newer unit still under warranty may need a different path. Check the paperwork before we start, and photograph the data label for any claim.
No two heaters cost the same, so we quote your actual job.
Tank size and type
A 50-gallon hybrid costs more than a basic 40-gallon electric tank.
Fuel and venting
Gas units need a flue, a gas connector and a draft check, which add time and parts.
Code upgrades
A missing pan, relief pipe or expansion tank may need to be added to meet current code.
Access and location
Attic, closet and second-floor installs take longer than a ground-level garage.
Permit and timing
A permit adds a step, and an after-hours dispatch costs more than a daytime appointment.
Insurance may cover sudden water damage but often not the heater itself. Call the 24/7 line and you get a clear price before work starts.
Call the 24/7 line, tell us the tank size and fuel, and we will send a licensed, insured plumber.
Water source and your new unit
Palm Beach County Water Utilities draws from the Biscayne Aquifer and uses chloramine. Hardness is not published in the reports we reviewed, so ask the utility at (561) 740-4600, because harder water means more scale and more frequent flushing.
Garage and closet installs
Many homes in the Village keep the heater in a garage or closet. A drain pan with a line to a safe spot protects drywall and flooring when the new tank eventually fails.
Check the license
Verify any plumber at MyFloridaLicense.com under Verify a License. Contractors are licensed under Chapter 489 by the Construction Industry Licensing Board.
Sources and standards
A replacement tank is installed to the Florida Building Code, Plumbing, 8th Edition (2023), the standard inspectors use. Palm Beach County publishes a like-for-like water heater change-out form for unincorporated areas, while the Village of Royal Palm Beach asks that you call (561) 790-5128 first.
Royal Palm Beach water heater replacement questions
Do you handle water heater replacement emergencies at night or on weekends in Royal Palm Beach?
Yes. The 24/7 line is answered through the night and on weekends, and we dispatch a licensed, insured plumber for failed or flooding tanks.
Same-day appointments are available when the schedule allows.
How do I know the tank itself is leaking?
Dry the unit and watch it. If water appears at the base, from the jacket or from the pan with no wet fitting above, the tank has failed.
Leaks that start at the top connections often turn out to be repairable.
How long does a replacement take?
It depends on the fuel, the access and any code upgrades. Many like-for-like swaps are a same-day job, but a fuel change or a venting fix takes longer.
We tell you the plan before we start.
Do I need a permit to replace a water heater?
Most work in the Village needs a building permit, and no water-heater-specific Village rule is published. Call the building department at (561) 790-5128 to confirm.
A county like-for-like form exists, but only for unincorporated areas.
Can I switch from a tank to a tankless unit?
Often, but gas line size, venting and electrical capacity must support it. See our tankless water heater page for what that conversion involves.
Should I replace the anode rod instead of the whole tank?
Only if the tank is still sound. A new rod slows corrosion but cannot reverse a liner that has already failed.
