Sump Pump Cleaning and Repair Done Right

Yes, a sump pump can be repaired, and in many cases, repair is the smarter call over replacement. Most failures come down to a few predictable problems: a stuck or failed float switch, a clogged intake screen, a burned-out motor, or a check valve that's letting water flow back down the discharge line. A proper sump pump cleaning service clears the pit and the intake before anything else, because a pump running against debris or pulling through a fouled screen will fail again inside a year no matter what else you do. Thomas Plumbing works through those diagnostics in order and tells you straight whether repair makes sense or whether the pump's age and condition put replacement ahead. Call for an honest look at what's actually wrong.

What drives cost on a sump pump job is mostly how complicated the situation is. A float switch swap or a quick cleaning is at the low end. A full pump replacement with a new discharge line run to daylight and a check valve installed correctly is at the higher end. Homes with old pits, cracked liners, or no pit cover at all add time and materials. Pedestal versus submersible pumps also affect the scope. Battery backup systems, if yours doesn't have one and you want one added, change the job entirely. Every job is different, contact Thomas Plumbing & Construction for an accurate estimate.

What Sump Pump Failure Actually Looks Like

Most homeowners notice the symptom before they identify the cause. Here's how to read what your pump is telling you.

01

Pump Runs But Moves No Water

This almost always points to a failed impeller or a blocked intake. The motor fires but nothing comes up the discharge line. Running the pump in this condition burns the motor out fast, so cut power and call before it turns into a full replacement.

02

Pump Won't Turn On

Float switch failure is the most common cause. The float gets stuck against the pit wall or the switch mechanism itself wears out. It can also be a tripped breaker or a dead GFCI outlet. Check those first, but if they're fine, the switch is the next suspect.

03

Pump Runs Constantly

A pump that never stops is either fighting a failed check valve (water cycles back in after each pump cycle) or the pit is taking on groundwater faster than the pump can handle. Either way, you're shortening the motor's life. Don't ignore it.

04

Strange Noise or Vibration

Rattling usually means debris in the impeller. A grinding or humming with no discharge means the motor's trying to work against a jam. Submersible pumps sitting directly on pit floor sediment often develop this, a cleaning fixes it when caught early.

05

Water in the Pit but Pump Doesn't Cycle

The float trigger level may be set too high, or the float is waterlogged and riding low. On older pedestal pumps the mechanical arm gets bent or corroded. This is one of the easiest fixes on the list, but only if someone actually checks it.

06

Discharge Line Frozen or Blocked

In cold snaps, discharge lines that terminate low to the ground can freeze solid. The pump fires, pressure builds, and either the check valve blows or the pipe joints separate. Crawl space flooding from a frozen discharge line is avoidable with the right termination setup.

How We Work

The Repair Process, Step by Step

  1. 01

    Inspect and Clean the Pit First

    We pull the pump, clear the pit of sediment and debris, and inspect the liner before we diagnose anything else. A dirty pit gives you wrong readings and hides cracks. This is where a sump pump cleaning service starts, not at the pump itself.

  2. 02

    Diagnose the Specific Failure

    Float switch, impeller, motor, check valve, discharge line, we test each component in order and identify exactly what failed and why. You get a straight answer on whether repair or replacement makes more sense before any work starts.

  3. 03

    Fix It and Confirm It's Working

    We do the repair, reinstall the pump correctly (not just sitting on the pit floor), and manually cycle it with water before we leave. The check valve gets checked. The discharge path gets confirmed. We don't call it done until we've watched it run.

Know the Difference

Repair vs. Replace: How to Think About It

A sump pump that's under five years old and failing because of a switch or a clogged screen is almost always worth repairing. Parts are cheap relative to a new pump, and the motor has years of life left if the underlying problem gets fixed. A pump that's ten or more years old, showing corrosion, running hot, or failing for the second time in two seasons is usually better replaced. Repairing an aging pump buys you time, not reliability. Honest answer: we'll tell you which situation you're in. We're not going to push a replacement when a forty-dollar switch is the real fix. That's not how you build a relationship with the people in your community. If you've also got a slow drain or a plumbing leak showing up around the same time, it's worth getting both looked at in one visit.

Our Process

Does Your Property Actually Need a Sump Pump?

  1. 01

    Crawl Space or Basement with Moisture History

    If you've had standing water, efflorescence on block walls, or that damp smell after heavy rain, a sump pump is the right fix. Rural properties on low-lying ground in Alamance, Chatham, and Orange County deal with this regularly, especially after the kind of soaking rains the region gets in spring.

  2. 02

    No Pump Installed Yet

    Older homes throughout the area were built without sump pits. If you're experiencing crawl space flooding and there's no pump in place, we can assess whether drain cleaning and grading fixes the issue or whether a full sump installation is the right call. We don't recommend pumps to people who don't need them.

  3. 03

    Battery Backup: Worth Adding

    The worst flooding happens during storms when the power goes out. A primary sump pump with no backup is useless right when you need it most. If your current setup has no battery backup, it's worth discussing when we're already on site. It's a straightforward addition and the cost is reasonable compared to what a flooded crawl space costs to remediate.

Sump Pump Problems We Fix

  1. 01

    Failed or stuck float switch

    The most common single-point failure on any sump pump.

  2. 02

    Burned-out or seized motor

    Usually caused by running dry, debris, or years of continuous cycling.

  3. 03

    Clogged intake and pit sediment buildup

    A full sump pump cleaning clears this and extends pump life significantly.

  4. 04

    Check valve failure and discharge line issues

    Backflow and blockages that make the pump work twice as hard.

Frequently asked questions

Can a sump pump be repaired, or does it always need to be replaced?
Most sump pumps can be repaired, especially when the failure is a float switch, check valve, or clogged intake rather than a dead motor. Age matters, a pump under five or six years old with a failed component is almost always worth fixing. One that's ten-plus years old and failing repeatedly is a different conversation. We'll tell you which situation you're in and let you decide.
What is the typical lifespan of a sump pump?
A submersible sump pump in normal residential use lasts roughly seven to ten years. Pedestal pumps often run longer because the motor sits above water, but the float mechanism and linkage wear out on their own schedule. Pumps that run constantly due to a high water table or a failed check valve burn out faster. Annual cleaning and inspection extend that lifespan noticeably.
What does a sump pump cleaning service actually involve?
A proper cleaning means pulling the pump out of the pit, clearing accumulated sediment and debris from the pit floor and walls, cleaning the intake screen, and inspecting the discharge line and check valve. Then the pump goes back in correctly, not just dropped on the pit floor where it sits in the muck it was just cleaned out of. We also cycle the pump manually to confirm it's working before we leave.
Do I call a plumber or a different contractor to fix a sump pump?
A licensed plumber handles sump pump repair and installation. It's plumbing work, the discharge line, the pit, the drainage path, and sometimes the connection to a drain cleaning or pipe repair situation are all in a plumber's scope. Thomas Plumbing handles the full job, including any related water issues around the crawl space or basement.
Why does my sump pump run constantly even when it hasn't rained?
A continuously running pump almost always means the check valve has failed. Water the pump pushed up the discharge line flows back into the pit once the pump stops, triggering the float again immediately. The pump never actually wins. Replacing the check valve fixes it. Less commonly, a high groundwater table during wet seasons can genuinely overwhelm a pump, but the check valve is the first thing to test.
How do I know if my sump pump discharge line is set up correctly?
The discharge line should terminate at least ten feet from the foundation, pitched downhill the whole way, and above grade so it drains clear rather than pooling near the house. Lines that terminate too close to the foundation just pump the same water back toward the pit. Lines that run underground and freeze in winter are a separate problem. If yours isn't draining cleanly away from the structure, that's worth addressing when you're already having the pump serviced.
