Sump Pump Emergencies During Storms: What to Do Right Now

If the rain just hit hard and your sump pump went quiet, seconds matter. Rising water can damage floors, appliances, and your electrical system fast. Take a breath—we’ll walk you through what to do right now and how to keep the water down until help arrives.

Billy Rogers Plumbing handles emergency plumbing around the clock, including sump pumps, battery backups, drain issues, and water heater safety. Our licensed techs size pumps correctly, calculate head height, and document tests so you know your system can keep up in the next storm.

Immediate Triage ⚡

Move step by step. These quick checks often restore a stalled pump in minutes.

• Verify safe footing first
  • If water is near outlets, extension cords, or appliances, do not step in. Turn off power at the main only if you can do so without standing in water. When in doubt, stop and call.
• Confirm the pump has power
  • Check the GFCI outlet. Press RESET. Many basements require GFCI by local code (based on the National Electrical Code); a nuisance trip can stop the pump.
  • Check the breaker. If tripped, reset once. If it trips again, stop—there may be a fault.
  • Plug in a phone charger or lamp to confirm the outlet is live.
• Inspect the pit (with the pump unplugged)
  • Remove the lid. Scoop out leaves, gravel, toys, and sludge with a plastic cup. Debris can jam the impeller or float.
  • Find the float switch. Lift it by hand. Reconnect power and test. If the pump runs with the float raised, the switch may be sticking.
• Check the discharge line
  • Feel the vertical pipe above the pump. If it vibrates or warms up but no water moves, the line may be blocked or the check valve stuck.
  • Outside, confirm the discharge point isn’t buried in mulch, ice, or snow. Clear it so water can flow away from the foundation.
• Reset and retest
  • Plug the pump back in. Raise the float. Watch for a firm stream at the outside discharge. If water recirculates into the pit, the check valve may be installed backward or failed.

If the water keeps climbing after these steps, move to damage control and a temporary bypass.

Reduce Damage Fast 🛟

Cut losses while you troubleshoot or wait for help.

• Protect people first
  • Keep kids and pets away from standing water and cords.
  • Wear rubber boots and insulated gloves if you must enter a damp area. Don’t touch metal appliances while standing in water.
• Move valuables and raise equipment
  • Elevate washers, dryers, and water heaters on blocks if safe and practical.
  • Move boxes, furniture, and rugs to higher ground. Put plastic bins under legs.
• Use wet/dry vacs smartly
  • Empty the tank often and dump water outside, well away from the foundation—never into a floor drain tied to the sanitary sewer (often prohibited by local code).
  • Do not use a shop vac in deep water where the plug or motor could be submerged.
• Create flow paths
  • Place towels or squeegee water toward a floor drain connected to a storm system, if allowed locally.
  • Open low windows or exterior doors briefly to improve airflow—only if safe from wind and driving rain.
• Power safety
  • If you’re running a portable generator, keep it outdoors, 20+ feet from doors and windows. Carbon monoxide is deadly. The CDC and CPSC both warn against indoor generator use.
  • Use heavy-duty, outdoor-rated cords and keep all connections off the floor.

Common Failures and Quick Fixes 🔧

These problems cause most mid-storm sump failures. Many have fast workarounds.

• Stuck float switch
  • Symptom: Water rises, pump silent. Lifting the float by hand starts the pump.
  • Action: Reposition the pump so the float swings freely. Remove zip ties or cords snagging it. Vertical rod floats can bind against the liner—rotate the pump a few degrees. Replace worn switches soon.
• Clogged or failed check valve
  • Symptom: Pump runs, water rushes back into the pit when it stops, cycling every minute.
  • Action: Verify arrow on the check valve points up (away from the pump). If the valve chatters loudly or leaks back, replacement is usually fast. In a pinch, run the pump continuously while you monitor water level to offset backflow until the valve is replaced.
• Blocked or frozen discharge line
  • Symptom: Pump hums, discharge pipe shakes, but no water exits outside; the pit level doesn’t drop.
  • Action: Clear the exterior outlet. In freezing weather, warm the termination with safe, indirect heat (not open flame). Attach a temporary discharge hose to the pump or interior piping and route it out a window to daylight away from the foundation. Keep kinks out of the hose.
• Tripped GFCI or breaker
  • Symptom: No power to the pump after heavy splash or surge.
  • Action: Reset once. If it trips again, stop and call. Repeated trips can mean a ground fault or a short in the cord or windings.
• Impeller jam
  • Symptom: Pump hums but doesn’t move water; may overheat and shut off.
  • Action: Unplug the pump. Lift it out if you can do so safely. Clear gravel or hair from the intake screen. Avoid running the pump dry—submersible pumps use water for cooling.

When to bypass with a portable utility pump

• If the primary pump won’t move water and a plumber can’t arrive before the level reaches equipment, a small utility pump can save the day.
  • Drop the utility pump into the pit or the lowest spot of water.
  • Attach a discharge hose and route it outside, downhill from the house.
  • Power it from a dry, GFCI-protected outlet using an outdoor-rated cord.
  • Monitor it. Many utility pumps aren’t automatic—don’t let them run dry.

Note: Follow manufacturer instructions. Many cities prohibit discharging to the sanitary sewer. When in doubt, discharge to the yard and keep flow away from your neighbors’ foundations.

Quick Safety Checklist ☑️

In a storm, speed matters—but safety matters more.

• If water is near electrical panels, outlets, or appliances, don’t wade in.
• Reset GFCI and breakers once only. Repeated trips mean stop and call.
• Keep generators outdoors. Carbon monoxide has no smell.
• Don’t combine extension cords. Use one long, heavy-duty cord.
• Keep children and pets upstairs.
• Wear boots and gloves; wash hands after cleanup. The CDC advises prompt drying to reduce mold growth.
• Never pump to a sanitary sewer. Many municipalities prohibit it.

DIY vs. Call a Pro 📞

Do-it-yourself you can try safely

• Reset a GFCI or breaker once.
• Manually raise a float with the pump unplugged, then test.
• Clear debris from the pit and the exterior discharge.
• Set up a portable utility pump bypass.
• Replace a surface-level check valve if you can shut off flow and keep fittings dry.

What Pros Do On Arrival 🧪

Here’s what our licensed sump specialists do to stop rising water and verify long-term reliability:

• Safety sweep
  • Check for electrical hazards, gas appliance clearance, and CO risks.
  • Confirm the pump circuit is safe to use or set up a GFCI-protected temporary circuit.
• Rapid pump diagnostics
  • Test voltage and amperage draw to spot motor issues.
  • Inspect the float, impeller, intake screen, and seals.
  • Open and test the check valve; replace if it’s chattering, stuck, or reversed.
• Head-height and capacity check
  • Measure vertical lift and horizontal run to calculate total dynamic head.
  • Compare your pump’s curve to the actual head and storm inflow rate.
  • If undersized, recommend a pump that matches the load with a safety margin.
• Restore flow
  • Clear or reroute a blocked discharge. Thaw frozen lines safely, add an exterior bypass if needed, and correct slope to reduce future freeze-ups.
  • Replace failed components with stocked parts (pump, check valve, unions, adapters).
• Backup and alerts
  • Install or service a battery backup or water-powered backup per local code and ASSE-listed backflow requirements.
  • Add a high-water alarm (audible + Wi‑Fi) and test it in front of you.
• Documented tests
  • Fill-test the pit to simulate a storm. Log pump start/stop levels, cycle rate, and run time.
  • Record amperage, head height, and discharge performance so you know the system can keep up.

Build Resilience 🔋

Storms will come again. Make your sump system tougher than the weather.

• Battery backup vs. water-powered backup
  • Battery backup
    • Pros: Works during power outages, doesn’t use city water, high flow with modern 12/24V systems, app alerts.
    • Cons: Batteries wear out (often 3–5 years). Needs charger and periodic tests.
  • Water-powered backup
    • Pros: No battery to maintain; runs as long as municipal pressure is stable.
    • Cons: Requires city water and a code-approved backflow preventer. Lower pumping rate. Adds to your water bill during use. Not allowed in some areas or on private well systems.
• Dual-pump setups
  • A larger primary pump plus a secondary (on a higher float) spreads the load when storms are extreme and reduces short-cycling.
• Dedicated electrical circuit
  • A properly grounded, dedicated circuit helps avoid nuisance trips. Many jurisdictions require GFCI in basements; check your local code based on the National Electrical Code and International Residential Code.
• High-water alarms
  • Add an alarm with a loud siren and a text/app alert. Place the sensor just above the normal pump-on level.
• Discharge routing
  • Ensure the outlet is at least several feet from the foundation, pitched to daylight, and not tied to the sanitary sewer. Splash blocks or solid pipe extensions help keep water away from the house.
• Sizing matters
  • Match pump flow to your worst-case inflow with a margin. Total dynamic head = vertical lift + friction losses + check valve lift. We size using manufacturer pump curves (Zoeller, Liberty, Wayne, etc.) and real measurements of your pit and piping.

Regional Nuance

Cold climates: freeze protection

• Use a larger-diameter discharge, minimize exterior runs, and include a slight downhill pitch so water doesn’t sit and freeze.
• Add a freeze guard or weep hole near the exterior termination so trapped water can escape.
• Insulate exposed piping and keep terminations clear of snow.

Coastal and hurricane-prone regions

• Expect long outages. Choose a high-capacity battery backup with extended runtime or a standby generator.
• Use check valves rated for salt-laden air and corrosion-resistant components.
• Elevate appliances and critical electrical components above historic high-water marks.

High water table or clay soils

• Consider a deeper pit with a sealed lid and a radon-rated, gasketed cover when required locally. A larger basin reduces short cycling and noise.

Prevention & Maintenance 🗓️

A simple routine keeps pumps reliable when storms hit.

Monthly (or before forecasted storms)

• Lift the float to verify the pump runs and the discharge flows.
• Check the pit for debris; clean the intake screen.
• Listen for chattering or banging in the check valve.

Quarterly

• Fill-test the pit with a few buckets to confirm start/stop levels.
• Inspect the exterior discharge for blockages and proper slope.
• Test the high-water alarm and app notifications.

Twice per year

• If you have a battery backup, test on battery power. Verify the charger and replace batteries per manufacturer guidance (often 3–5 years).
• Inspect union fittings and supports for leaks and vibration.

Annually

• Have a licensed plumber perform a documented system check:
  • Electrical safety and amperage draw
  • Head-height measurement and pump curve review
  • Check valve performance
  • Discharge routing and freeze protection
  • Backup system capacity test and backflow preventer inspection (where installed)

Costs & Time Factors ⏱️

Every home is different, but here’s what affects cost and timing during a storm:

• Access and water level
  • Deeper water, tight pits, or corroded fittings take longer to service.
• Parts and pump type
  • Pedestal vs. submersible, 1/3 HP vs. 1/2 HP or larger, cast iron vs. thermoplastic, and whether a special check valve or unions are needed.
• Electrical and discharge corrections
  • Adding a dedicated circuit or rerouting a discharge takes additional labor and materials.
• Backup systems
  • Battery backups vary by capacity and monitoring features.
  • Water-powered backups need a code-approved backflow device and proper tie‑in.
• After-hours demand
  • Peak storms push many homes into emergency at once. We’ll give clear arrival windows and temporary steps to keep water down.

Typical ranges (parts and labor; not quotes)

• Primary pump replacement: often in the $450–$1,200 range depending on size and materials.
• Check valve replacement or reorientation: often $150–$350.
• Discharge thawing and repair: often $200–$600, more if re-routing outside.
• Battery backup systems: often $800–$2,500 depending on capacity and alerts.
• Water-powered backup (where allowed): often $900–$2,800 including backflow protection.
• Temporary utility pump setup: varies; many customers purchase in the $100–$300 range.

We’ll explain options and get your approval before work proceeds.

When It’s an Emergency 🚨

Treat it as an immediate emergency if:

• Water is within a few inches of your furnace, water heater, boiler, or electrical panel.
• You smell smoke or see sparks, or breakers won’t reset.
• The sump pit fills faster than the pump can empty.
• The discharge line has burst inside the house.
• You have only one pump and no backup during a known long outage.

Call as soon as you notice rising water. Early calls help us route techs and get you on the board before conditions worsen.

Local/Seasonal Considerations

Power-outage–prone neighborhoods

• Add a battery backup with extended runtime or a properly sized standby generator installed to code by a licensed electrician. Use an interlock or transfer switch—backfeeding is dangerous and illegal.

Homes with combined interior drains

• If your laundry sink or floor drain ties into storm piping, heavy rain can reverse flow. We can add check protection or reconfigure drains to reduce risk.

High-silt or iron-rich water

• Sediment and iron bacteria can gum up floats and impellers. More frequent cleaning and an intake screen help. We may recommend a pump model better suited to your water chemistry.

Basements finished with carpet and drywall

• Install a high-water alarm that notifies your phone. Consider a water sensor strip under baseboards in the lowest room.

Rental properties and multi-family buildings

• Add tamper-resistant covers and signage. Post the emergency plumbing number in common areas.

FAQ ❓

How long can a sump pump run continuously?

• Many units can run for extended periods if fully submerged and cool. Short cycling (rapid on/off) shortens life. If your pump runs non-stop for hours, consider upsizing or adding a second pump and a larger basin.

Should my sump pump be on a GFCI?

• Many jurisdictions require GFCI protection in unfinished basements. Some local codes have exceptions for dedicated sump circuits. Follow local code and manufacturer guidance. If a GFCI trips repeatedly, call a pro—there may be a ground fault.

Can I discharge to a laundry sink or floor drain?

• Usually no. Many municipalities prohibit pumping to the sanitary sewer. Discharge to daylight or a storm system if allowed. We can reroute your discharge legally and safely.

Why does my basement smell musty after a flood?

• Moisture feeds mold. The CDC advises drying within 24–48 hours. Run fans and dehumidifiers, remove wet materials, and clean hard surfaces with appropriate disinfectants. If water touched insulation or drywall, replacement is often needed.

How often should I replace the pump?

• Many pumps last 5–10 years, but runtime, water chemistry, and maintenance matter. Annual testing and documentation help you replace on schedule, not in a crisis.
