Water in Your Sump Pump? Here Are 5 Possible Reasons Why and What You Should Do Next

On February 25, 2026  By newsroom   Topic: Home Services


1. Clogged Discharge Line

  • Problem: The discharge line, which moves water away from your home, may be blocked by dirt, pebbles, or debris.
  • Solution:
  • Disconnect the sump pump from its electrical source.
  • Attempt to manually unclog the discharge line.
  • If sediment buildup is deep within the pipe, call a professional with specialized tools.

2. Frozen Discharge Line

  • Problem: Freezing temperatures can turn water in the discharge line into ice, stopping drainage.
  • Solution:
  • Shut off the pump's power at the circuit breaker.
  • Use a wet vac or hand pump to remove standing water.
  • Place a space heater near the pump (at a safe distance).
  • Pour boiling water directly into the pit or discharge pipe to melt the ice.

3. Float Sensor Problem

  • Problem: The float sensor, which triggers the pump when water levels rise, may:
  • Be stuck on the pit's side.
  • Have failed due to age (typically lasts ~7 years).
  • Be affected by a power failure.
  • Solution:
  • Temporary fix: Manually turn the pump on to prevent overflow during heavy rainfall.
  • Permanent fix: Hire a pro to repair or replace the float sensor. Pros typically charge $45–$65/hour.

4. Faulty Valve

  • Problem: A malfunctioning valve can send drained water back into the sump pump pit, causing standing water.
  • Solution:
  • Hire a professional to inspect and replace the valve.
  • Valve replacement typically costs around $20, with labor being the primary expense.

5. High Water Table

  • Problem: If your home is positioned near a high water table, the sump pump may be overwhelmed during rain or snow.
  • Solutions:
  • Reposition the sump pit:
    • Relocate the pit further from the water table.
    • Cost: Approximately $1,300 (similar to sump pump installation costs).
  • Add a second sump pump:
    • Install another pump in the pit to handle excess water.
    • Costs range from $60 to $400 for the pump, plus increased electricity usage.

Summing it up

  • Regular maintenance is crucial to prevent clogs, freezing, and sensor issues.
  • Some problems, like frozen pipes, are DIY-friendly, while others (e.g., faulty valves or high water tables) require professional intervention.
  • Pro repair costs typically range from $45–$65/hour, and sump pump installations average around $1,275.
