Sump Pump Issues We Fix

If your sump pump is showing signs of failure, don’t wait for a major storm to find out it’s not working. Here are some of the most common issues we fix:

  • Sump Pump Not Turning On: This may be caused by a faulty float switch, electrical issue, or motor failure.
  • Frequent Cycling On and Off: Short cycling often results from an incorrectly sized pump or a bad pressure switch.
  • Strange Noises or Vibrations: Grinding, rattling, or humming could indicate debris inside the pump or a failing motor.
  • Standing Water in the Pit: If water isn’t being discharged, the pump may be clogged, burnt out, or the check valve may have failed.
  • Air Lock in Discharge Line: This prevents proper water flow and can cause backup even when the pump is running.
  • Discharge Line Leaks: Cracks or loose fittings can reduce pumping efficiency or cause water to leak near your foundation.

A One Stop Shop for All Sump Pump Repairs

Whether your sump pump has stopped working or just doesn’t seem to be keeping up, we’re here to help. Our experienced technicians diagnose the issue quickly and make sure you’re protected from the next storm.
  • Sump Pump Diagnostics

    Not sure what’s wrong? We start with a full system inspection—including the pump, float switch, electrical connections, and discharge line—to pinpoint the issue.

    Common diagnostic findings include:
    • Jammed or misaligned floats
    • Burned-out motors
    • Tripped circuit breakers
    • Improper pump sizing or placement

    Once we’ve identified the problem, we’ll explain your options clearly and provide a fast path forward.

  • Float Switch Repairs

    The float switch is the part of your sump pump that tells it when to turn on and off. If it gets stuck or wears out, your pump won’t activate properly—or may run nonstop.

    We’ll test the float mechanism and:
    • Adjust or clean it for free movement
    • Replace worn-out switches
    • Secure the switch to prevent tangling

    Many sump pump failures can be traced back to float switch issues—and we’ll get yours working again fast.

  • Clog & Obstruction Removal

    Sump pumps often fail because debris blocks the intake or impeller. If your pump hums but doesn’t pump, this is usually the issue.

    Our team will:
    • Disconnect and inspect the pump housing
    • Clear sediment, gravel, or sludge buildup
    • Flush and test the system for flow

    We’ll also recommend a cover or screen if your pit lacks protection from debris.

  • Check Valve & Discharge Repairs

    The check valve keeps water from flowing back into the pit once the pump shuts off. If this valve fails or the discharge line leaks, your system won’t perform efficiently.

    We repair or replace:
    • Broken or stuck check valves
    • Leaking discharge pipe connections
    • Frozen or cracked exterior piping

    We’ll ensure water is flowing safely away from your home.

  • Battery Backup Troubleshooting

    If you have a secondary pump and it’s not activating, we’ll inspect the battery, charger, and controller system.

    Typical issues include:
    • Dead or corroded batteries
    • Faulty float activation
    • Loose or damaged wiring

    We’ll restore your backup system so you’re covered during power outages and heavy storms.

Karen Helsel

We found Crystal Water Plumbing when our well pump stopped working. They came out, diagnosed and gave us an estimate, and then repaired the two-fold problem (both the pressure switch and the pump itself had failed) within the day. They also noticed other items, and quickly addressed all of the issues, and now we have a well that should give us decades of worry-free service.
