Sump Pump Emergencies During Storms: What to Do Right Now

When a storm hits and your sump pump stalls, every minute matters. Rising water can damage floors, drywall, appliances, and wiring. We understand the stress of watching water creep toward the furnace or water heater—especially in the middle of the night.

H.I.S. Plumbing provides 24/7 emergency plumbing service for storm-related sump pump failures. Below you’ll find immediate steps to protect your family and home, safe backup options during a power outage, and a storm-readiness plan to prevent the next emergency.

🌧️ The Problem: Storm Surge + Sump Pump Failure

Heavy rain, snowmelt, and high water tables push groundwater against your foundation. Your sump pump is the last line of defense. Common storm failures include:

• Loss of power to the pump or GFCI trip
• Stuck float switch or failed check valve
• Clogged intake screen or blocked discharge line
• Overwhelmed pump (capacity too low for the inflow)
• Discharge frozen or buried under debris

The result: water rises in the pit, overtops the basin, and floods the floor. The goal is to slow the water, restore safe pumping fast, and keep you safe around electricity and contaminated water.

✅ Quick Safety Checklist

• Keep people and pets away from standing water near electrical outlets, appliances, or the panel.
• Do not wade into water if you can’t confirm power is off to that area.
• Wear rubber boots and gloves if you must enter a damp area.
• Ventilate the space; avoid breathing in fumes from ozone generators or fuel-based equipment.
• If you smell gas, leave the area and call your gas utility and 911.

Authoritative references for safety include the National Electrical Code (NFPA 70), OSHA electrical safety in wet locations, and FEMA flood safety guidance.

⚠️ Immediate Actions

Personal safety comes first. Then move to fast fixes that can restore pumping or slow the rise.

• Cut power if cords or outlets are submerged

  • If water reached outlets, cords, or the power strip, shut off the circuit at the breaker panel. Do not touch cords in water.
  • If the electrical panel is wet or inaccessible due to water, do not attempt to reach it—call your utility or emergency services.

• Check the float, discharge line, and reset GFCI

  • Unplug the pump while you inspect. Lift the float by hand; if it’s stuck against the basin wall, re-position it so it moves freely.
  • Inspect the intake screen; remove leaves, silt, or hair.
  • Press the GFCI reset on the outlet that feeds the pump. GFCI protection is recommended by the National Electrical Code for basement outlets near moisture.
  • Follow the discharge line outside. Clear snow, ice, mulch, or debris that may block the outlet. Make sure the line slopes to drain away from the foundation.

• Use a backup pump or wet/dry vacuum

  • If the primary pump is down, set a portable utility pump or battery backup pump in the pit. Discharge water outside and away from the foundation.
  • You can also wet-vac the pit to buy time, emptying the tank outside between fills. Avoid sending flood water into floor drains if your sewer is stressed—it can back up.

• Avoid overloading circuits

  • Do not plug multiple pumps into one extension cord or power strip. High startup amperage can trip breakers and overheat cords. Use heavy-duty, grounded extension cords rated for wet locations.

• If water is approaching utilities

  • Turn off gas to appliances if safe to do so. Keep clear of submerged furnaces and water heaters. If the water reaches the gas valve, call a professional.

• Remove valuables

  • Elevate boxes, electronics, and furniture. Move stored items to higher shelves. Place drywall-edged items on blocks to avoid wicking.

Insurance and Documentation

• Photograph the water level, damaged items, and the failed pump.
• Keep receipts for pumps, hoses, generator fuel, and professional service.
• Note dates/times of peak water and when power was lost or restored.
• Save any model/serial tags from damaged equipment.
• Contact your insurer promptly; many policies require quick notice. Don’t discard damaged items until your adjuster advises.

⚡ Power Outage Options

Storms often knock out power right when groundwater surges. Plan for one of these:

• Battery backup systems

  • A battery backup sump pump sits in the basin beside the primary pump. When power fails, it kicks on automatically.
  • Choose a system with a high-capacity, deep-cycle battery (often AGM). Expect 4–12 hours of runtime depending on battery, inflow, and pipe height.
  • Keep the charger and control panel off the floor. Test monthly.

• Water-powered backups (where allowed)

  • These use municipal water pressure to eject sump water via an ejector venturi. They require proper backflow prevention and are not permitted everywhere.
  • Verify local code requirements (Uniform Plumbing Code/IAPMO or International Plumbing Code). Backflow testing may be required to protect the drinking water supply.

• Portable generator safety

  • Operate outdoors at least 20 feet from doors and windows. The CDC warns of deadly carbon monoxide from generators placed in garages or near openings.
  • Use a transfer switch or interlock kit installed to code by a licensed electrician, per NEC and manufacturer instructions. Avoid backfeeding through dryer or range outlets.
  • Fuel safely—cool before refueling and store fuel in approved containers away from ignition sources.
  • Protect cords from water and trip hazards; use GFCI protection.

If you’re unsure which backup fits your home, H.I.S. Plumbing installs code-compliant sump systems and can coordinate with electricians for dedicated circuits or transfer switches.

🛠️ Prevent the Next Emergency

A little prevention goes a long way—especially in regions with high water tables and frequent storms.

• Annual service essentials

  • Clean the pit: remove silt, gravel, and debris so the float and impeller move freely.
  • Test the check valve: confirm the arrow points away from the pump and listen for short run times (a failed valve causes water to fall back and rapid cycling).
  • Verify discharge distance: discharge outdoors, downslope, and at least several feet from the foundation so water doesn’t return.

• Upgrade smart safeguards

  • High-water alarms: audible siren plus text/app notifications warn you early.
  • Dedicated circuit and GFCI: reduce nuisance trips and keep the pump on a protected circuit as required by code.
  • Redundant pumping: pair a primary pump with a secondary pump on a separate float. Add a battery or water-powered backup where allowed.
  • Freeze protection: insulate or upsize exterior discharge and use a freeze-resistant outlet.

• Storm-readiness checklist

  • Test pump and alarm before storm season.
  • Clear gutters, downspouts, and yard drains; extend downspouts well away from the house.
  • Confirm the sump lid seals to limit debris and humidity.
  • Keep spare parts: float switch, hose clamps, and a short length of discharge hose.
  • Store a wet/dry vac and utility pump where you can reach them quickly.

• Whole-home protection

  • Seal foundation cracks, add interior drain tile where needed, and consider a backup power plan.
  • If your area sees frequent sewer surges, ask about backwater valves and backflow prevention—H.I.S. Plumbing performs backflow testing and installs prevention devices.

🚨 When It’s an Emergency

Call immediately if:

• Water reaches the furnace, water heater, electrical panel, or finished walls.
• You hear arcing, smell burning, or see smoke at outlets.
• The pump runs continuously without lowering water (possible failed check valve or blocked discharge).
• Sewer water backs up through drains. That requires urgent sewer line inspection and may involve backflow issues.
• You have an infant, older adults, or anyone with respiratory conditions at home—standing water can promote mold within 24–48 hours (CDC guidance).

H.I.S. Plumbing is available 24/7 for emergency plumbing. We also handle leak detection, toilet repair, drain cleaning, water heater repair, and more while we’re on site.

❓ FAQ

• Why is the pump running but the water isn’t going down?

  • The impeller may be jammed, the check valve stuck, or the discharge blocked or frozen. The pump could also be undersized for the inflow.

• Can I run my sump pump on an extension cord?

  • Only as a short-term measure using a heavy-duty, grounded cord suited for wet locations. Avoid daisy-chaining or lightweight cords. Permanent setups should use a dedicated, properly grounded circuit.

• How long should a sump pump last?

  • Many last 5–10 years depending on cycles and water conditions. If yours is older than 7 years or runs constantly during storms, plan for replacement and add a backup.

• Should the discharge line freeze in winter?

  • It shouldn’t. Insulate exposed sections, upsize the pipe if needed, and use a freeze-resistant outlet. Ensure the pipe has continuous slope to drain.

🗺️ Local and Seasonal Considerations

• High water table areas
  • Homes built on clay soils or near lakes and rivers see frequent inflow. Redundant pumps and battery backups are especially important.
• Hurricane and monsoon seasons
  • Stacked storms mean days of saturated soil. Ensure daily tests and keep batteries fully charged.
• Spring snowmelt
  • Warm snaps can overload pumps for weeks. Add an alarm and consider a second discharge line to reduce backpressure.
• Freezing climates
  • Protect exterior discharge from ice dams. Consider a cold-weather check valve and a bypass to an alternate outlet.

🧼 After the Water Recedes: Clean-Up Notes

• Remove wet drywall at least 12 inches above the waterline to prevent mold wicking.
• Disinfect hard surfaces and dry the area within 24–48 hours (CDC mold remediation guidance).
• Run a dehumidifier; keep relative humidity below 50%.
• Inspect gas appliances before re-lighting; call for service if controls were submerged.
