In Alexandria, a sump pump that stops working tends to show itself in a heavy storm, when an older basement starts collecting water at the walls or the floor joint. A plumber can sort out whether you need a part, a new pump, a backup or protection against sewer backups. Call the number on this page to be connected with a local plumber in Alexandria.
Alexandria conditions
Alexandria grew from an 18th-century river port, and the city still mixes Old Town rowhouses and older close-in neighborhoods like Del Ray with denser West End and Potomac Yard buildings. The median home was built in 1974. Basements are common in the detached houses and older rowhouses, and many of them were finished long after the original drainage was put in.
The City owns the sanitary sewers and the City-owned portions of laterals, and AlexRenew treats the wastewater. Part of Old Town is served by a combined sewer area, where storm runoff and sewage share pipes. That matters in a big storm, because water in a basement can come from groundwater, from a backed-up sewer line, or both. The City also offers homeowners a reimbursement for backflow preventers installed on their sewer laterals, which is worth asking about if a floor drain has ever backed up.
One boundary note: Alexandria mailing addresses in ZIPs such as 22306 through 22312 and 22315 are largely unincorporated Fairfax County. Those homes follow Fairfax County permit and sewer rules, not the City's.
Comparing your options
| Option | Good fit when | Alexandria angle |
|---|---|---|
| Replace a part | Stuck float, failed check valve, tripped outlet | Quickest fix before the next storm |
| New pump | Seized motor, cracked housing, constant cycling | Older basements often have undersized original pumps |
| Battery backup | Power drops during summer storms | No connection to drinking water |
| Sewer lateral backflow preventer | A floor drain has pushed up sewage before | The City offers a reimbursement for these |
Signs it needs attention
- Water sits in the basin and the pump stays silent
- Rapid on-off cycling during light rain
- A grinding or rattling motor
- A wet strip where the floor meets the wall
- Sewage odor or gray water around a basement floor drain
Seasonal timing
Test the pump in spring, before the heavy thunderstorms that roll through the region in summer, and again in late fall. Winter brings a different issue: a discharge line that runs across the yard can freeze shut, which leaves the pump pushing against ice. A plumber can reroute or slope the line so it drains out between cycles.
