Sump Pump Installation & Repair in Arlington, VA

Is a Sump Pump Right for Your Home?

Sump pumps aren't universal, but for the right home, they're one of the more valuable basement protection investments available. Properties with a history of basement moisture, homes on lower-lying lots relative to neighbors, and any home with a finished basement — where water damage is meaningfully more costly — are the strongest candidates.

Why Battery Backup Matters in Arlington

The scenario a primary electric sump pump can't handle — a power outage during a major storm — is exactly when a basement is most at risk. Heavy storms that overwhelm drainage are frequently the same storms that knock out power via downed lines or utility strain, leaving a primary pump offline exactly when it's needed most.

How Battery Backups Work

A battery backup system runs a secondary pump off a deep-cycle battery, automatically activating if the primary pump loses power or fails mechanically — buying critical hours during a storm rather than leaving the basement completely unprotected.

Water-Powered Alternatives

In homes on municipal water pressure (not well water), a water-powered backup pump is another option that doesn't rely on a battery at all, instead using household water pressure to eject sump water — a reasonable alternative for homes without a reliable way to maintain a battery.

Troubleshooting a Sump Pump That Won't Turn On

A non-functioning sump pump often goes unnoticed until the next heavy rain, which is exactly the wrong time to discover it.

Check the Float Switch

The float switch triggers the pump once water reaches a certain level — debris in the pit can obstruct its movement, preventing it from rising enough to trigger activation.

Check Power and the Outlet

Confirm the pump is plugged in, the outlet has power, and the breaker hasn't tripped — GFCI outlets in particular can trip silently without an obvious sign.

Test Manually

Pouring several gallons of water into the pit and watching whether the float rises and triggers the pump confirms whether the issue is mechanical or electrical before we even open a tool bag.

Discharge Line Issues, Including Winter Freezing

A frozen discharge line is a specifically winter problem — the pump works fine, but the water it's pumping has nowhere to go once the exit line freezes solid. The pump cycles on but the water level in the pit doesn't drop, or you'll hear it running longer than usual without the expected discharge sound outside. A properly sloped discharge line that drains fully after each cycle, rather than holding standing water, resists freezing far better than a flat or improperly graded line — worth checking during installation or a fall maintenance visit.

Sump Pump vs. Full Basement Waterproofing

These solve different parts of the same problem. A sump pump removes water that's already entered the basement — the last line of defense once water is inside. Exterior waterproofing and interior drain tile systems aim to prevent water from getting in at all, addressing the source rather than managing the symptom. Many homes genuinely need both: a sump pump without addressing why water keeps entering just means the pump works harder than it should, while waterproofing without a pump leaves no way to remove whatever still gets through during extreme events.
