How a water heater repair & replacement call goes, start to finish
A water heater that has stopped making hot water is not always a water heater that needs replacing. A failed element, a burnt-out thermostat or a broken dip tube are all cheap repairs on a tank with years left in it, and we check before quoting a replacement.
When replacement is the right answer, the decision is tank against tankless. Tankless costs more to install, needs a larger gas line and correct venting, and never runs out. A tank is cheaper, simpler and perfectly good if your hot water demand is not the problem. We will price both.

Why Your Hot Water Smells Like Rotten Eggs
If the smell is only on the hot tap, the water is fine and the water heater is not. It is a reaction inside the tank, and it has a specific fix.

FAQ
Your water heater repair & replacement questions, answered by a plumber
Should I repair or replace my water heater?
Repair it if it is under about ten years old and the fault is a part — a thermocouple, an element, a thermostat, a gas valve. Replace it if the tank itself is leaking, because a tank cannot be repaired, or if it is past twelve years and the repair costs a large share of a new unit. Nashville hard water shortens tank life, so a heater here often reaches that point sooner than the label suggests.
How long does a water heater replacement take?
Most of a day for a like-for-like tank swap, including draining the old unit, fitting the new one, and bringing the connections up to current code — an expansion tank, a proper pan and drain, seismic strapping. Switching from tank to tankless takes longer because the gas line and venting usually need upsizing, and that can turn one visit into two.
Is a tankless water heater worth it in Nashville?
For a household that runs out of hot water, yes; for one that does not, the payback is slow. Tankless units heat on demand and never run out, but Middle Tennessee water is hard enough that the heat exchanger needs descaling every year or so, and skipping that is what kills them. Budget for a water softener or an annual flush as part of the decision, not after it.
