Water Heater Repair in Jacksonville, FL
Jacksonville's water comes from the Floridan Aquifer and is hard, so sediment and scale are behind many water heater problems here. A rotten-egg smell from the hot tap is also common and usually comes from the heater's anode rod reacting with sulfur compounds in the water.

What is different about water heater repair in Jacksonville?
The smell is the local signature. If only the hot water smells, the cause is inside the heater: the magnesium anode rod that protects the tank reacts with naturally occurring sulfur compounds. A plumber can flush and disinfect the tank and fit an anode made of a different material, which usually solves it without replacing the heater.
Most heaters here are electric tanks in a garage or utility closet. Hard water buries the lower element in sediment until it overheats and fails, giving a short burst of hot water and then cold. Flushing the tank and replacing elements is a routine repair. After any flooding, a heater that was underwater should be inspected before use.

Hard-water scale
Aquifer water leaves sediment in tank heaters and scale on tankless units.

Water Heater Repair questions from Jacksonville
Is sulfur-smelling hot water dangerous?
The odor is unpleasant but is usually a nuisance issue caused by the anode reaction inside the heater. If cold water also smells, or you have other concerns, contact JEA or your water provider.
Can I just remove the anode rod to stop the smell?
That is not recommended. The anode protects the tank from corrosion, and removing it shortens the tank's life and can void the warranty. Replacing it with a different type addresses the smell and keeps the protection.
