In Morrow, a failing water heater usually needs one part, such as an element, a thermostat, a thermocouple or a relief valve, and a plumber can generally replace it in one visit. A tank leaking through its own wall must be replaced. Call the number on this page to be connected with a local plumber in Morrow.

Morrow is a small, diverse city along I-75, anchored by Southlake Mall and Clayton State University and home to the Georgia Archives. Its housing is older than average: census estimates put the median build year at 1971, with roughly 62% of homes built before 1980. Clayton County Water Authority, headquartered in Morrow, supplies water and sewer and installs a backflow device at every customer connection, testing it each year with its own staff. That device keeps heated water from expanding back into the main, so homes without a thermal expansion tank often see the relief valve drip after each heating cycle.
Do these things first
- Gas smell first. If you smell gas, leave the house without touching switches, then call 911 and Atlanta Gas Light at 877.427.4321 from outside.
- Stop the water. Close the valve on the cold line feeding the top of the tank. For a large leak, shut the main at the meter.
- Cut the energy. Switch off the heater's breaker, or turn a gas control to off or pilot.
- Find the source. Note whether water comes from the relief pipe, the drain valve, a top fitting or the tank bottom.
- Look for an expansion tank. It is a small tank on the cold line near the heater. Tell the plumber whether you have one.
- Read the label. Model, serial number and fuel help the plumber bring the right parts.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Relief valve drips after heating | No expansion tank, or a waterlogged one |
| Steady drip from the relief pipe | Worn valve |
| No hot water | Element, thermostat, pilot or thermocouple |
| Hot water runs short | Lower element, sediment, dip tube |
| Water under the tank | Drain valve, fittings or failed tank |
| Rusty hot water | Anode rod or internal corrosion |
What affects the cost
- The part. Elements and thermocouples are routine; gas valves cost more.
- Pressure control. Adding or recharging an expansion tank adds parts and time.
- Older connections. Original valves and nipples in 1960s and 1970s homes often need replacing.
- Permit. The City of Morrow's Planning & Economic Development Department issues plumbing permits through Community Core or paper forms at City Hall.
CCWA owns the service line to the meter; from the meter to the house is the owner's. For a large leak on the authority's side, its line is 770-960-5200.
