When a failed tank is an emergency
A tank that is leaking from its body, flooding a utility room, or leaving a household with no hot water in cold weather is an emergency. Water heaters hold 40 to 50 gallons in a typical home, and a weeping seam can become a flood within hours.
Our crews carry or can source the common sizes, so a same-day swap is realistic for standard replacements. Specialty sizes, tight closets and venting changes can add a day. We will tell you at the first call which category you are in.
| Option | Good fit | Trade-off |
|---|---|---|
| Standard gas tank | Homes with a gas line and a working flue | Needs venting and a gas connection check |
| Standard electric tank | Homes without gas, or where the old unit was electric | Needs a correctly sized circuit |
| Hybrid heat pump tank | Homeowners focused on running cost | Needs clearance and air space, larger footprint |
| Tankless | Households wanting endless hot water and wall space | Higher installed cost, see tankless water heater |
What a replacement visit involves
Shut down
We isolate water, power or gas, and drain the old tank safely.
Remove
The old tank comes out of the house and is taken away.
Set and connect
The new unit is set on a pan or stand, with fresh supply lines, a relief valve and a discharge pipe.
Test
We fill the tank, purge air, check for leaks, test venting and gas connections, and show you the shutoffs.
Sizing the new heater for your household
A tank that is too small runs out of hot water by the second shower. One that is too large wastes energy keeping extra gallons hot. We size by number of people, number of bathrooms and whether you run a soaker tub, a dishwasher and a washer back to back.
Measure nothing yourself. Tell us what you have, and we will check the nameplate on the old unit and suggest an equal or better size. If you are weighing an upgrade, our water heater installation page covers how a planned installation differs from an emergency swap.
Venting, expansion tanks and code points that matter
A gas water heater has to vent its exhaust through a flue sized for the unit. A replacement that changes fuel type or capacity may require changes to that venting. Most homes also need a thermal expansion tank on the cold supply when a backflow device or pressure reducing valve closes the system, and a pan and drain line where a leak could damage finished space.
Georgia's state minimum plumbing code is built on the International Plumbing Code with Georgia amendments, and local jurisdictions inspect against it. Permit rules vary, so ask the City of Tucker permit team whether your swap needs a permit. Tucker's Building and Permitting office inspects work at different stages, and we can describe what we plan to do so you can ask the right question.
What to clear before the crew arrives
- A path from the front door to the heater, free of boxes and furniture.
- Floor space around the tank, since the old unit comes out in one piece.
- Pets secured. Doors will be open while the tank moves.
- The make and size printed on the old tank's label, if you can read it safely.
Replacement cost factors
Tank type and size
A 50-gallon gas unit and a hybrid heat pump unit are in different price classes.
Venting changes
A new flue liner or relocated vent adds parts and time.
Code items
Expansion tank, pan, drain line and updated shutoffs are added when the situation calls for them.
Access
Attic and crawlspace installs are slower than garage or closet installs.
Warranty term
Longer manufacturer warranties usually come with higher-grade tanks.
A sudden tank failure may be covered under homeowners insurance for water damage even when the heater itself is not. Take photos before cleanup. For your real number, call (770) 214-4545 and tell us the size, fuel and location of the old unit.
Tank down and no hot water?

Replacement in Tucker houses: what we see
Tank heaters in Tucker-area homes sit in garages, closets, basements and attics, and each spot changes the job. A unit in an interior closet needs a drain pan and clearance. One in a garage needs protection from impact. An attic unit needs a safe path for the old tank to come down.
If the heater serves a house in Lilburn or Norcross, the same crew and the same pricing approach apply, since we dispatch across the DeKalb and Gwinnett line from Tucker.
If your heater is still working but past its useful life, planning the replacement before it fails costs less and lets you pick the model. If it has already failed, the information above still applies, and the only difference is how fast we move. For a leak you are not sure about, first read about water heater repair.
Homeowners in the subdivisions around Idlewood can read the page for their area, since the houses there were built across several decades and heaters of different ages are common.
What to do before we arrive
- Turn off the power or gas to the heater and close the cold water valve.
- Open one hot tap in the house to relieve pressure.
- Move belongings away from the heater and place towels around the base.
- If you smell gas, leave the house and call the gas utility from outside.
Standards and sources
Plumbing work in Georgia follows the state minimum plumbing code, which is built on the International Plumbing Code (IPC) with Georgia amendments. Ask the City of Tucker permit team which edition and which local rules apply to your address. Plumbers are licensed through the Secretary of State's Division of Master and Journeyman Plumbers, and you can ask for a license number. Gas piping and venting for water heaters fall under the National Fuel Gas Code, NFPA 54, as adopted locally.

Questions we hear from homeowners
Yes. The line answers 24 hours a day, and a plumber can usually be scheduled the same day for standard replacements. The price is agreed before work begins.
A straightforward swap of the same type and size typically takes a few hours. Fuel changes, new venting and tight access take longer.
Yes. Removing the old unit is part of the job, and we confirm that when we quote the replacement.
Permit rules vary, so ask the City of Tucker permit team. We can describe the scope so your question to them is specific.
Only if the wall space, gas line size and budget fit. We compare both honestly on the tankless page, and many households are better served by a new tank.
