Quick answers
- Primary sumps need electricity — no power, no pump.
- Battery backup and water-powered backup are different tools; compare before you buy.
- Never bypass a GFCI that trips on a sump circuit — find out why with an electrician.
- After the storm: check the pit, backup status, and discharge before you assume you are fine.
When to use this guide
Use before severe thunderstorm or high-wind watches, or after an outage when you are unsure whether the sump ran.
Definition: water systems that need power
Sump pumps, sewage ejectors, and some well pumps stop when the circuit dies. Water heaters and supply lines may still hold pressure, but basement protection does not. Generators and transfer switches are electrician territory; battery backup units are a common plumbing-side mitigation.
When to prepare (not during the flash)
Test the float, confirm a dedicated or appropriate receptacle strategy with an electrician if needed, install backup before peak season, and keep discharge clear of debris after wind events.
Failure modes
Assuming “we rarely lose power,” running extension cords through standing water, or resetting breakers in a wet basement. Those are life-safety failures, not DIY tips.
Action
Book a sump + backup inspection in calm weather. During/after an outage, follow the after-a-storm act page and call if water is rising.
Failure modes to avoid
Waiting until the watch is issued to buy a backup
Inventory sells out and install slots fill. Pre-season visits exist for a reason.

FAQs
Can you wire a new sump circuit?
No. We install/service the pump and plumbing. New circuits, GFCI replacement, and generator interlocks are licensed electrician work. We coordinate when both trades are needed.
Battery or water-powered backup?
Depends on water pressure, pit layout, and how long outages last on your block. See our compare page for a calm decision framework.
