What's actually causing this
Toilets run when water continuously trickles from the tank into the bowl. The two most common culprits are a worn-out flapper that doesn't seal properly, and a fill valve that's stuck open or set too high.

Step-by-step fix
-
1
Diagnose the problem
Lift the tank lid and add a few drops of food coloring. If color appears in the bowl within 10 minutes without flushing, the flapper is leaking.
-
2
Turn off the water supply
Turn the shutoff valve behind the toilet clockwise. Flush once to empty the tank.
-
3
Replace the flapper
Unhook the old flapper from the overflow tube pegs. Snap the new flapper in place and reconnect the chain — leave about half an inch of slack.
-
4
Adjust the fill valve
If water is running over the overflow tube, the water level is too high. Adjust the float arm or float ball downward until the water sits 1 inch below the top of the overflow tube.
-
5
Turn water back on and test
Slowly open the shutoff valve. Let the tank fill and listen for any continued running after the fill cycle completes.
In Atlanta, tap water is soft (50–90 ppm). Atlanta's water is soft, sourced from the Chattahoochee River. Mineral buildup on fixtures is minimal. Corrosion from soft water (pin-holing in copper) is a concern in older homes. Water softeners are less common than in hard-water areas.
Plumbers in Atlanta typically charge $90–150/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Georgia requires state licensing for master plumbers. Homeowner exemptions exist for minor work. Atlanta requires city permits and inspections.
Mix of pre-1950s and post-1960s construction. Older homes may have galvanized piping with corrosion. Soft water can cause pin-holing in copper piping. Most newer homes have copper or PVC. Humidity means condensation and mold risk on exposed pipes.
Freeze risk in Atlanta is minimal — hard freezes are rare. Pipe insulation is generally not a concern, though occasional cold snaps can surprise under-prepared homes.
DIY in Atlanta: Atlanta's moderate licensing requirements and growing DIY culture make it reasonably friendly for homeowner repairs. Humidity management and moisture prevention are key DIY focuses. Most people hire contractors for major electrical and HVAC work.
- The tank or bowl has visible cracks.
- The toilet rocks or is loose at the base — this may indicate a wax ring failure.
- Water appears on the floor around the base after flushing.
