Why Your Sump Pump Matters Most in Late Winter (And How to Test It)

February 11, 2026

Winter may be winding down, but in the NY Metro and Long Island area, February is still one of the most critical months for preventing flooding and water damage—especially for commercial properties. Snow, ice, and heavy winter storms often lead to melting snow and rising groundwater levels, increasing the risk of water intrusion in basements, mechanical rooms, elevator pits, and lower-level spaces.

That’s where your sump pump system becomes a key part of protecting your building and avoiding costly disruptions.

At Atlas Pump Repair Corp, we’ve been keeping pump systems running reliably since 1958. Here’s why late winter is such an important time for sump pump performance—and how to test your system to make sure it’s ready when it matters most.

Why Late Winter Is Critical for Sump Pumps

By February, accumulated snow and ice often begin to melt, increasing runoff and groundwater pressure around commercial foundations. Even a minor backup or pump failure can lead to major consequences, including:

  • Water damage to flooring, walls, equipment, or stored materials

  • Mold or mildew growth

  • Foundation or structural issues over time

  • Costly emergency repairs and downtime

  • Disruptions for tenants, staff, or building operations

In Long Island and the NY Metro region, properties located in low-lying areas or near high water tables are especially vulnerable. Heavy snowmelt and winter rainstorms can overwhelm older or poorly maintained sump pump systems, making preventative checks essential.

Signs Your Sump Pump Needs Attention

Before testing, look for these common warning signs:

  • Unusual Noises – Grinding, rattling, or humming may indicate mechanical issues

  • Visible Leaks or Corrosion – Check the pump and surrounding piping for rust or water staining

  • Frequent Cycling – A pump that runs constantly may be undersized or struggling to keep up

  • Power Issues – Tripped breakers, faulty outlets, or unreliable power can prevent activation during a surge event

How to Test Your Sump Pump

A quick test can help prevent expensive water damage and unexpected emergencies. Here’s a simple step-by-step process:

1) Check Power & Connection

Make sure the pump is plugged in and the circuit is functioning properly.
If your system includes a battery backup, confirm the battery is fully charged and operational.

2) Inspect the Discharge Line

Confirm the discharge pipe is clear of ice, snow, or debris, and that water is being directed safely away from the building.

3) Perform a Float Test

  • Slowly pour a bucket of water into the sump pit

  • Watch the float switch activate the pump

  • Confirm the pump discharges water properly

  • Make sure it shuts off once the pit empties

4) Clean the Pit and Pump Area

Remove dirt, gravel, or debris that could clog the intake or interfere with float movement. Keeping the pit clean helps the system perform during peak demand.

5) Schedule a Professional Inspection

If you notice unusual noises, slow performance, frequent cycling, or leaks, it’s time to call a professional. A trained technician can service, repair, or replace components before failure occurs.
