Is Your Water Heater Leaking? A Marietta Diagnostic Walkthrough
How to spot the source of a water heater leak in Marietta, GA and what each leak type means for your next move. Call (770) 555-0100.
Find the source first
A leaky water heater is rarely just one thing. The location of the drip tells you whether you need a $20 fitting or a full replacement. Wipe the unit dry, then check four spots: the cold inlet, the hot outlet, the T&P discharge line, and the floor under the tank.
Drip from the top connections
Water at the cold inlet, hot outlet, or along the supply lines usually points to a fitting, a flex connector, or a shutoff valve. Most of the time you are under $200 in parts and labor across Marietta. Older homes around the Marietta Square or off Whitlock Avenue still hide galvanized risers that corrode at the threads, and swapping the union usually clears it.
Drip from the T&P discharge
If the temperature and pressure relief valve is dripping, the system is either over-pressured or the water inside is too hot. Cobb County mains can sit above 80 PSI in pockets near Cumberland and Vinings, which makes the T&P weep. A pressure regulator on the main plus a properly sized expansion tank usually fixes it. If the valve still drips after that, the valve itself is done.
Drip from the base of the tank
This is the bad one. Water pooling on the slab under the tank means the tank wall has pitted through. There is no real fix. The unit gets replaced. If your tank is past 8 years old in Marietta, this is a common end. Cobb County water sits at 3 to 5 grains, which sounds harmless, but ten years of cycles is enough to eat the anode and start on the steel.
