No hot water: what to check before you call
A water heater that stops making hot water, or makes only lukewarm water, usually has a short list of causes. Checking a few things first can tell you whether the fix is a reset or a repair, and it gives the plumber a head start.
| Check | Gas water heater | Electric water heater |
|---|---|---|
| Power or fuel | Is the pilot lit, and does the gas supply valve sit open? | Has the breaker tripped, and is the reset button on the unit popped? |
| Thermostat | Is the dial set to a working temperature? | Are both thermostats set the same, and is the upper one working? |
| Sound | A click with no flame points to the igniter or thermocouple | Silence with a warm tank points to a failed lower element |
| Water at the base | Moisture can be condensation or a real tank leak | Moisture around the base points to a leak, not a power fault |
If a pilot will not stay lit or you smell gas at any point, stop and treat it as a gas emergency.
Gas vs electric water heater repair
Gas water heater repair and electric water heater repair share a tank but not much else. Gas units depend on a burner, a pilot or igniter, a thermocouple or flame sensor and a flue that carries exhaust out. Electric units depend on heating elements, thermostats and a breaker. Hot water heater repair starts by identifying which one you own, since the label on the tank names the fuel.
Thermostat, element and electric faults
A thermostat or element failure on an electric unit is a common reason for warm-but-not-hot water, and both parts are replaceable. A tripped breaker that trips again points to a shorted element, which a plumber should confirm before resetting it repeatedly.
Pilot, igniter and burner faults
Pilot light and igniter problems, a dirty burner or a failing flame sensor are the usual causes on a gas unit, and burner heater service includes cleaning and testing the safety shutoff. Water heater plumber calls for gas units also check the flue and the vent, because a poor draft is a safety problem as well as a performance one.
Water heater leaking right now?
Call the dispatch line and say whether the unit is gas or electric. A plumber serving your area takes it from there.
Leaking tank versus leaking fitting
A leaking water heater can have a simple cause or a final one, and telling them apart is the whole decision. Check where the water starts: a drip at the inlet, outlet or relief valve is a fitting or valve problem, while water coming out of the tank's body or seam, or pooling under the unit with no fitting wet, is a leaking tank.
| Where it leaks | Likely cause | Typical outcome |
|---|---|---|
| Supply connections at the top | A loose or worn fitting or flex line | Repair the connection |
| Temperature and pressure relief valve | A worn valve, or pressure or heat that is too high | Replace the valve and look for the cause |
| Drain valve at the bottom | A weeping valve | Replace the valve |
| The tank itself, around the base or a seam | Corrosion has breached the tank | Replace the water heater, since a breached tank cannot be patched |
Picture a 15-year-old tank with rust streaks and a puddle that returns every morning. That is a corroded tank, and no repair outlasts it. In that case plan for water heater replacement instead of paying for another visit. If the floor is wet or carpet is soaked, water damage restoration information handles the drying.
While you wait for a plumber, turn off the cold supply valve on top of the tank, cut power or gas to the unit and place a pan or towels at the base. Appliance water heater leaks do their worst damage when a tank empties quickly, so shut the water off before anything else.
Repair or replace? How long water heaters last
How long do water heaters last? A typical gas or oil-fired storage tank lasts about 8 to 12 years, according to InspectApedia's review of sources, and tankless units run longer. A unit near the top of that range that needs a part is a reason to compare a repair with a hot water tank replacement. A newer unit with a failed thermostat is a straightforward repair.
Source: InspectApedia.Replacement needs a permit in Roswell
A new tank in Roswell triggers the city's plumbing and gas code review, with a permit and an inspection attached. Georgia licensing rules apply to the tradesman as well. A part repair leaves the unit in place, but ask the person quoting whether any gas or venting changes come with it.

Water heater repair install questions, such as whether to move to a high efficiency water heater or a tankless model, are covered on the tankless water heater page. Cost is discussed on the cost factors page.
Flushing, sediment and noises
Water heater maintenance is short and worth doing. Flushing a tank clears sediment that settles at the bottom, which insulates the water from the burner or element and causes popping or rumbling as it heats. Popping noise is a sediment sign, not usually a failure, but a tank that has never been flushed can be hard to drain. A plumber can flush the tank, check the anode rod and test the relief valve in one visit.
Roswell water is soft
Hardness scale is an uncommon cause of heater trouble here because the utility's own report calls the supply soft. Age, sediment and worn parts matter more.

Emergency water heater repair is available through the 24/7 emergency plumber line when a tank is leaking or there is no hot water at night.
No hot water and it is after hours?

Water on the floor that is not the water heater
Not every wet floor near a water heater is the water heater. North metro Atlanta homes often have basements, and a wet basement after a storm may be groundwater coming through the wall, not a plumbing leak. Check whether the water appears only when it rains, whether the water meter moves with everything off and whether the tank and pipes are dry.

Roswell water heater repair questions
How long do water heaters last in Roswell?
About 8 to 12 years for a typical gas storage tank, with electric units often a few years longer. Soft supply water makes scale less of a factor here, so age and sediment matter most. A unit past ten years that needs a repair is worth comparing with replacement.
I have a wet basement after a storm. Is it the water heater?
Local fact first: north metro Atlanta homes often have basements, and groundwater after heavy rain can seep through the wall or floor joint. The water heater is the cause only if the water appears without rain, the meter moves with everything off or water is coming from the tank or its pipes. Dry the area and call if the tank is wet.
My 15-year-old tank is rusty and leaking. Can it be repaired?
Picture rust streaks down the tank and a puddle that returns each morning. A tank that leaks from its body cannot be patched, and at that age a new unit is the sensible answer. Close the cold water valve above the tank, cut the power or gas and call. A leak from a fitting or valve is a different case and often repairable.
There is an outdoor water leak. What should I do now, and what can wait?
Right away: watch the meter with every fixture off, and close the main valve if it moves. Later: a slow drip at a hose bibb or a wet patch with no meter movement can be booked as a scheduled repair. A leak between the meter and the house is on your side, and the yard line is a separate job from the water heater.
