In a townhouse, a leaking water heater is a problem for two homes, so act on a leak first: shut the valve on the cold pipe above the tank, cut the heater’s power at the panel or turn its gas knob to off, and check the floor along any shared wall. If there is no leak, only cold water, the breaker or the pilot is the first thing to look at. For water heater repair in Sunrise, One Call Home Pros then matches you with a vetted, licensed, insured local professional who works on tank and tankless heaters every day. You explain the problem once, and we handle it from there.


Why Sunrise homes need careful water heater repair
Sunrise is large and suburban, and most of it was built between the 1970s and the 1990s. It also holds a big share of Broward County’s townhouse stock. That last point shapes heater work here more than anything else.
Townhouses are built with common walls. The heater in one unit often sits a few inches of block or drywall away from the next unit’s living room, kitchen or own heater closet. Plumbing stacks, the vertical drain and vent pipes, can be shared between units, and in some buildings so are water shut-offs. A repair that would be simple in a detached house has to account for the neighbours on either side.
The single-family houses from the same decades bring their own issues: heaters on their second or third replacement, original valves and connectors, and closets built for smaller tanks. Both kinds of home are now at an age where water heaters fail regularly.
Heater faults a pro can look at
Stone-cold taps
A heater with no output at all. Often a breaker, an upper element, a thermostat or a gas pilot that has gone out.
Showers that cool too soon
A failed lower element, a broken dip tube or a tank lined with sediment.
Water where it should not be
A weeping relief valve, a loose connector or a rusted-through tank.
Knocking and crackling
Sediment hardening in the tank, often louder through a shared wall.
Discoloured or smelly hot water
A spent anode rod, or one reacting with standing water.
Time for a new heater
A tank or tankless unit chosen to fit a townhouse closet and the supply it has.
Common walls change the job
When a heater leaks in a detached house, the water stays on your property. In a townhouse it can run under the bottom plate of a common wall and appear in the next unit before it appears in yours. Drywall wicks it upwards, and baseboards and flooring next door can be damaged before anyone sees a puddle.
So check the wall, not only the floor in front of the heater. Look at the base of the wall behind and beside the closet, and if there is any doubt, tell your neighbour and ask them to look at their side. When you call One Call, mention that the heater backs onto another unit. The pro will check the wall and the floor around the heater as part of the diagnosis and tell you whether water has travelled.
Common walls also limit what can be changed. Cutting a new vent, moving the heater or running a larger gas line through a party wall is often restricted by the building code and by the association, and sometimes not allowed at all.
Shared stacks and shared shut-offs
In some townhouse buildings, a single main valve controls the water to more than one unit, or the valve for your unit sits in a neighbour’s space or a common utility room. Find out where yours is before you need it. The management office or the association can tell you.
Shared drain stacks matter too. A heater’s relief line and pan drain have to discharge somewhere safe, and in a townhouse that is sometimes an indirect connection near a shared stack. If the drain backs up when the heater’s pan drains, the problem may be in the stack, which is a plumbing matter and often the association’s responsibility. The heater pro checks that the heater’s own lines are correct and tells you where the fault lies.

Where townhouse heaters are tucked away
Floor plans from the 1970s to the 1990s put the heater wherever there was a spare corner. In Sunrise townhouses, look for it in one of these places:
- A closet under the stairs
- A utility closet off the kitchen or the laundry area
- A small closet on the upper floor, sometimes inside a bathroom or off the landing
- The single-car garage, where there is one
- An outside closet on a patio or by the front door
Tell One Call where yours is. Each location changes what the pro brings, how a new tank gets in, and how much damage a leak can do.
Heaters upstairs
An upstairs heater is the one that does the most damage when it leaks. Water goes straight down through the floor into the ceiling of the room below. A drain pan under the tank, with a line that actually runs to a drain, is the minimum protection. Many older installations have a pan that drains nowhere, or no pan at all.
If your heater is on the upper floor, ask the pro about a leak sensor that sounds an alarm, or an automatic valve that closes the cold supply when it detects water. On a replacement, the pan and its line should be part of the job. During any water heater repair in Sunrise townhouses with upstairs closets, the pro also checks the relief line, which should run to a safe point and never be capped.
Before the pro arrives
These steps keep things safe and help the pro arrive ready:
- Close the valve on the cold pipe entering the heater.
- Turn off the heater’s breaker, or set the gas knob to off.
- If water is still coming out, run a hose from the drain cock at the base of the tank to a floor drain or outside, and open it slowly.
- Check the shared wall and tell the neighbour if water may have reached them.
- Photograph the label for the make, model and serial number.
- Find out what the association needs from a contractor.
If you smell gas, leave the home and phone the gas utility from outdoors. An electric tank that has been drained must never be powered up again until it is full.

A gas heater needs air
A gas heater burns fuel inside the closet, so the closet needs a supply of air for combustion. That is why many gas heater closets in townhouses have louvred doors or vents in the wall or ceiling. When a louvred door is swapped for a solid one, or the vents are blocked by stored boxes, the burner starves. The flame turns lazy and yellow, the pilot goes out, soot gathers at the top of the heater, and in the worst case exhaust spills back into the home.
If your gas heater keeps losing its pilot, or you notice soot or a sharp smell near the closet, turn the gas control off and call rather than relighting it over and over. The pro checks the combustion air, the vent and the burner together. A carbon monoxide alarm near any gas appliance is a sensible companion to all of this.

What the pro tests
Diagnosis follows the fuel. On an electric tank, the pro checks the supply voltage at the heater, then each element and thermostat in turn, and the high-limit switch. A heater with no hot water usually has a problem with the upper half of that circuit; one with too little usually has a problem with the lower.
On a gas tank, the pro checks the pilot or igniter, the thermocouple or flame sensor, the gas valve and the burner, and looks at the vent to be sure the flue gases are leaving the house. In a townhouse, the vent path may be long and run through an upper floor, and the pro will check it end to end.
On a tankless unit, the error code is the starting point, then the inlet filter, the heat exchanger, the flame rod and the flow sensor. Most faults on any of these heaters are repairs. Only a tank that leaks from its body is beyond one.
Getting a new tank through a narrow doorway
Townhouse closets and stairs were not designed with heater replacement in mind. A new tank has to travel through the front door, along a hall, sometimes up a flight of stairs, and into a closet with little clearance. Current tanks meet newer efficiency rules and can be wider or taller than the old one.
The pro measures the closet, the door and the route before choosing the replacement. Sometimes a slightly smaller or a lowboy tank is the right answer; sometimes the closet door frame has to come off for the swap. Clearing a path from the door to the closet before the visit saves time.
Single-family houses from the same decades
Not every home in Sunrise is a townhouse. The detached houses from the 1970s to the 1990s usually keep the heater in the garage or a utility room, which makes access easy and a leak less costly. Their issues are those of age: valves that have not been turned in years, galvanized or corroded fittings at the tank, no expansion tank, and pans that drain nowhere.
Water heater repair in Sunrise single-family homes is often a good moment to deal with these. Replacing a stiff valve or adding an expansion tank while the water is off is a small addition to the visit, and the pro will tell you what they found and what each item involves before doing it.

Rows built together, heaters failing together
Townhouse rows went up as a single project, and the heaters in them were often fitted within weeks of each other. Replacements since then have scattered the dates a little, but in many rows a cluster of heaters reaches the end at around the same time. If your neighbour’s tank has just failed and yours is of similar age, take it as a warning.
Planning a replacement before the tank leaks is usually easier than reacting to one, especially in a home where a leak reaches next door. The pro can look at a heater that is still working and tell you how it is doing: the state of the anode rod, the amount of sediment, any rust at the fittings and how well it recovers after use. That gives you time to choose a replacement and arrange the association paperwork without a cold shower forcing the timing.
If you rent the townhouse
If you rent, the heater usually belongs to the owner, and the repair is the owner’s decision. Tell the owner or the managing agent straight away, make the heater safe with the steps above, and pass on what you have seen. The owner can then call One Call, or ask you to, and we arrange the visit with whoever needs to give access and approve the work.
Tankless in a townhouse
Tankless heaters are appealing in a townhouse because they free up a closet. The practical hurdles are real, though. A gas tankless unit needs a gas line sized for it and its own vent to the outside, and a townhouse may have no route for either that does not cross a common wall or the roof the association controls. An electric tankless unit needs a large electrical supply, often more than a townhouse panel can give.
The pro can tell you what your unit could support, including the gas meter’s capacity, the panel’s spare capacity and where a vent could legally end. In many townhouses, a well-sized tank in the existing closet is the realistic option, and that is worth knowing before you plan around a tankless unit.
Noise through a shared wall
Heaters make noise, and common walls carry it. Sediment pops and rumbles as the burner or element heats the water under it. Pipes tick as they expand. A relief valve that hisses or a tank that knocks at night can be heard next door.
Most of these noises point to something the pro can deal with. A sediment flush quietens a popping tank. An expansion tank stops the pressure surges that make pipes bang. Pipe clips and padding stop ticking where pipes touch framing. If a neighbour has mentioned noise, say so when you call. Note when it happens, too: a rumble only while the heater is firing points to sediment, a bang just after a tap closes points to water hammer, and a hiss or a trickle when nothing is running can mean the relief valve is letting by. Each has a different fix, and the timing helps the pro tell them apart before opening anything up.
Keeping a townhouse heater healthy
A heater in a tight closet is easy to ignore. A few habits help it last:
- Keep the closet clear so the valves, the panel covers and the pan are reachable
- Have the tank flushed and the anode rod checked during any visit
- Test the relief valve lever now and then, with a bucket under the line
- Know where your unit’s main shut-off is and make sure it turns
- Look at the floor around the heater whenever you open the closet

Paying, financing and permits
You pay One Call, and One Call pays the pro. Ask what the price covers before work begins, including removing the old tank, a new pan and line, new valves and connectors. Financing is available on a replacement; ask about it when you call.
A replacement usually needs a permit and an inspection, which the licensed pro arranges under their own licence. One Call holds no trade licence. In a townhouse community, the association may need notice or paperwork as well.
How One Call matches you
When you call, One Call asks what the heater is doing, its fuel, its location in the home and whether it shares a wall with a neighbour. We choose a vetted, licensed, insured local professional who works on heaters in homes like yours, and stay with the job until it is done. For water heater repair in Sunrise, as for water heater repair in Tamarac and water heaters in Plantation, the process starts with one call.
Questions from Sunrise
My heater leaked and the neighbour’s wall is wet. What now?
Shut off the heater’s water and power, tell the neighbour and the association, and call. The pro confirms the source and whether water has travelled.
Can I move my townhouse heater to free up a closet?
Sometimes, but moving it means new water, power or gas and venting, often through common walls. The pro checks what the building allows.
Why can my neighbour hear my water heater?
Common walls carry sound. Popping usually means sediment, and banging can mean pressure surges. Both can usually be fixed.
Will a new tank fit up my stairs and into the closet?
The pro measures the route and the closet first, and chooses a tank that fits, sometimes a lowboy or a slightly smaller one.
