About 62% of Morrow homes were built before 1980, with a median year of 1971, so a water heater replacement here often includes new valves, vent parts or pipe. The city's Planning and Economic Development Department issues plumbing permits. 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 Clayton County Water Authority's headquarters. Its housing is mostly from the 1960s and 1970s, so many heaters are on their fourth or fifth tank with original fittings still in place.
What to do now
- Close the cold supply on the pipe entering the top of the heater.
- Turn off the power or gas to the heater.
- Clear the area and soak up water before it reaches flooring or walls.
- Do not relight a gas heater that has been sitting in water; let the plumber check it.
- Smell gas? Leave first, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. Marketers on your bill do not handle leaks.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water leaking from the bottom | Rusted-through tank |
| Rusty hot water | Internal corrosion or old galvanized pipe |
| Pilot keeps going out | Thermocouple, draft or control valve |
| Hot water runs out fast | Sediment or a broken dip tube |
| Corrosion at the top fittings | Old dielectric unions or galvanized nipples |
Cost factors
- Type, fuel and capacity of the new heater
- Replacing old valves, nipples and connectors
- Vent connector updates on gas units
- Closet or utility room access
- City permit and old-tank disposal
The City of Morrow Planning and Economic Development Department issues plumbing permits; applications go through a Community Core online account or paper forms at City Hall, and the department number is 770-961-4002. Clayton County Water Authority provides water and sewer; its service line runs to the meter, and the line from the meter to the house is the customer's. CCWA tests residential backflow devices itself, so that is not part of your heater job. Ask the plumber whether the city permit is included in the quote, and whether the price assumes the old vent and gas cock can be reused. In homes this age they often cannot, and listing those parts up front keeps the final bill predictable. If you have been thinking about a tankless unit or moving the heater out of a cramped closet, raise it on the first call so both options can be priced on one visit.
