When an Alpharetta sump pump quits, it's usually a stuck float, a failed check valve, a tripped outlet or a worn motor. A plumber can get it running and keep the discharge on the yard instead of in the Fulton County sewer. Call the number on this page to be connected with a local plumber in Alpharetta.

Alpharetta at a glance
Alpharetta is an established north Fulton suburb and tech hub, with mostly 1980s to 2000s subdivisions; about 57% of homes were built between 1980 and 1999, and the median build year is 1996, per census survey data. Many basements and crawl spaces still have the pump installed with the house. The city doesn't run water or sewer; Fulton County Public Works provides both, and the owner is responsible for the sewer lateral from the house to the property line. That's why pumped groundwater has to go to the yard rather than into a cleanout or laundry drain: it ends up in county sewer.
What to do right now
- Turn off power to the pump at the breaker if water is near the outlet or the pump. Don't step into standing water near electricity.
- Look into the pit. If the float is pinned against the wall or tangled in the cord, free it gently with a dry stick once power is off.
- Restore power and listen. A hum with no water moving points to a jammed impeller or failed motor.
- Go outside and check the discharge outlet for leaves, dirt or a crushed pipe.
- Move belongings off the basement floor and lift rugs.
- Take a photo of the pit and the outdoor outlet so you can show the plumber what you saw.
- If the pump still won't keep up, call for help.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Pit full, pump silent | Stuck float, tripped GFCI or dead motor |
| Pump runs, water level steady | Clogged intake, broken impeller or blocked discharge |

What affects the cost
- A single part versus a full pump replacement
- Pump capacity for the inflow on your lot
- Finished basement access
- Rerouting a discharge that ends too close to the house
- Battery backup and alarm; a water-powered backup brings Fulton County's annual certified backflow testing
- A city trade permit through Alpharetta's online portal if piping or wiring changes
- Replacing a cracked or silted basin
