If it's leaking
A. O. Smith says to cut power or gas and close the cold water valve at the top of the tank before anything else (A. O. Smith). Step-by-step: water heater leaking: what to do.
The relief valve
A. O. Smith's bulletin says the temperature and pressure relief valve is a safety device, normally rated for 210°F, with a pressure rating at or below the tank's working pressure, generally 150 psi. Intermittent weeping can come from thermal expansion in a closed system, while a large burst of hot water points to a malfunctioning thermostat (A. O. Smith).
Repair or replace
A. O. Smith says a leak from the base of the tank means corrosion has eaten through the steel and requires replacement, and that most leaks signal the heater is at the end of its life or needs immediate repair (A. O. Smith). Atlanta's plumbing permit form lists replacing a water heater as work that needs a permit (City of Atlanta).
Checking the plumber
Georgia licenses plumbers through the Secretary of State. The state does not register plumbing companies, and only licensed master plumbers may run a plumbing business (Georgia Secretary of State). A Class I master plumber license covers single-family homes and one-level homes for up to two families; Class II has no restrictions (Georgia Secretary of State). Ask for the master plumber's name and check it in the state's licensee search.
