Sump Pump Repair, Replacement, and Battery Backup in Metro Detroit
A sump pump is the only thing standing between a high water table and your basement floor, and it is a single mechanical device with a working life of roughly seven to ten years. Drain Detectives repairs, replaces, and installs sump pumps and backup systems across Macomb, Oakland, Wayne, and southern St. Clair County from our Fraser, Michigan shop, including emergency response when a pump quits mid-storm.

Water rising in the pit right now? If the pump is not running and the pit is filling, this is an emergency. Move anything valuable off the floor and call.
(586) 296-0036 (248) 645-2448Test Your Sump Pump Before You Need It
Almost every failed sump pump we are called to had been sitting unused since the last wet season. Do this now rather than finding out during a storm.
- Lift the lid and look in the pit. Clear out gravel, silt, or debris around the intake.
- Slowly pour a few gallons of water into the pit with a bucket until the float rises.
- The pump should switch on by itself, empty the pit, and switch off cleanly without chattering or short cycling.
- Go outside and confirm water is actually coming out of the discharge, well away from the foundation.
If it did not start, ran but moved nothing, kept running after the pit emptied, or you heard a hum with no water moving, it needs service before the next storm. A pump that fails this test in July is an inconvenience. The same pump failing in April is a finished basement.
What a Failing Sump Pump Does First
| What you notice | Usually means | What it needs |
|---|---|---|
| Runs constantly, even when it is dry outside | Stuck float, undersized pump, or groundwater entering faster than expected | Diagnosis before it burns out the motor |
| Switches on and off rapidly | Short cycling from a failed check valve, a pit that is too small, or float positioning | Check valve or float service |
| Hums but nothing moves | Jammed or seized impeller, often debris in the pit | Service, sometimes replacement |
| Runs but the pit stays full | Blocked or frozen discharge line, failed impeller, or a check valve stuck shut | Urgent. The pump is working and the water is not leaving |
| Vibrating or rattling loudly | Damaged impeller or a pump that has shifted in the pit | Inspection, likely replacement |
| Visible rust or staining in the pit | Corrosion, or iron bacteria in the groundwater fouling the pump | Assessment. Iron bacteria shortens pump life considerably |
| Silent when the pit is full | No power, tripped breaker, failed switch, or a dead motor | Emergency if water is rising |
| Seven to ten years old and untested | Statistically near the end of its service life | Test it now, budget for replacement |
Your Pump Fails Exactly When You Need It Most
This is the part homeowners underestimate. The heaviest rain of the year is also when the power is most likely to go out. A sump pump with no backup is a device that stops working at the precise moment groundwater peaks.
| Setup | How it works | Protects against | Limits |
|---|---|---|---|
| Single pump, no backup | One electric pump on household power | Normal groundwater only | No protection from outage, pump failure, or a stuck float |
| Battery backup system | A second DC pump on a deep cycle battery that takes over automatically | Power outages and primary pump failure | Runtime is limited by battery capacity, and the battery needs periodic replacement |
| Water-powered backup | Uses municipal water pressure to draw water out, with no electricity at all | Extended outages, since runtime is not limited by a battery | Requires adequate city water pressure, uses potable water while running, and is not permitted in every municipality |
| Dual primary pumps | Two pumps sharing the pit, the second staged higher | Mechanical failure and volume beyond one pump's capacity | Still both on household power, so an outage takes out both |
| Backup plus alarm | Any backup, paired with a high-water alarm or monitor | The failure happening while nobody is home | Only useful if somebody can act on the alert |
If your basement is finished, a backup system is not an upgrade. It is the difference between a pump repair and a flooring, drywall, and contents claim.
The Discharge Line Is Where Winter Gets You
A sump pump can be in perfect condition and still flood your basement if the water has nowhere to go. In Southeast Michigan the discharge line freezes, and it freezes at exactly the wrong time, when a thaw sends meltwater into a system whose outlet is still iced shut.
- The pump keeps running and the pit stays full. That combination almost always means a blocked or frozen discharge, not a bad pump.
- Slope and length matter. A line that holds standing water freezes solid. It needs to drain fully between cycles.
- Discharge point matters. Water dumped too close to the foundation runs straight back into the drain tile and returns to the pit, which is a loop that runs the pump to death.
- Check the outlet before winter. Clear the end of the line, make sure it is not buried under mulch, snow, or landscaping, and confirm it still drains freely.
If your pump is cycling constantly in winter or the pit is not clearing, have the discharge checked before you replace a pump that may be working fine.
What Actually Matters in a Replacement
-
Submersible or pedestal
Submersible pumps sit in the pit, run quieter, and handle debris better. Pedestal pumps keep the motor above the water and are easier to service. Most Metro Detroit basements get a submersible.
-
Capacity, not just horsepower
Horsepower alone tells you little. What matters is how much the pump moves against the height it has to lift and the length of the run. A pump that is oversized short cycles. Undersized, it never catches up.
-
Switch type
The float switch is the most common failure point in the whole system. Switch design and how it sits in the pit matter more to reliability than the brand on the housing.
-
Check valve and pit
A working check valve stops discharged water falling back into the pit, which prevents short cycling. Pit size and a proper lid affect performance, humidity, and safety.
Why Metro Detroit Basements Take On Water
- Clay soil and a high water table. Much of Macomb and Oakland County sits on heavy clay that drains slowly. Water does not soak away, it sits against your foundation and finds the path of least resistance.
- Spring thaw stacked on spring rain. Frozen ground cannot absorb meltwater, so it runs sideways. Add a April storm on top and groundwater rises fast.
- Older drain tile. Footing drains in older homes silt up over decades, so water that should be intercepted and routed to the pit finds the floor instead.
- Combined and surcharged sewers. Parts of the older regional system carry both storm and sanitary flow. During heavy rain the public main can surcharge, and the lowest opening in your house is where that shows up. A sump pump does not solve that particular problem, which is worth understanding before you buy one.
What a Sump Pump Will Not Fix
Basement water has more than one cause, and a pump only addresses one of them. Knowing which problem you have saves you from buying the wrong solution.
-
It does not stop a sewer backup
A sump handles groundwater. Sewage coming up through a floor drain is a sanitary line problem, and the defense against that is a backwater valve and a healthy sewer lateral, not a bigger pump.
Sewer repair -
It does not seal a leaking foundation
Water entering through a wall crack or at the wall-floor joint needs the crack addressed or proper drainage installed. A pump can only remove what actually reaches the pit.
Waterproofing -
It does not fix bad exterior drainage
Downspouts discharging at the foundation and grading that slopes toward the house send water straight down against the wall. That is a yard problem, and no pump size compensates for it.
-
It does not work without drain tile
A pit with no drain tile feeding it only collects what happens to reach that one spot. If your basement takes water in a corner far from the pit, the collection system is the issue.
Where Your Discharge Is Allowed to Go
Many Metro Detroit municipalities prohibit connecting sump pump or footing drain discharge into the sanitary sewer, and several communities in this region have run disconnection programs over the years. Sump water is groundwater, and sending it into the sanitary system contributes to the same surcharging that backs sewage into basements during heavy rain.
Rules vary by city, and so do requirements about how far discharge must be from the foundation and whether it can cross onto a neighboring property. If you are having a system installed or a discharge rerouted, we confirm the local requirement for your address as part of the work. If you inherited an existing connection when you bought the house, it is worth finding out what you have.
What Drives the Price
- Repair versus full replacement, and whether the pit and discharge are reusable
- Pump capacity needed for your water volume and lift height
- Whether you are adding a backup system, and which type
- Condition of the existing pit, lid, check valve, and discharge line
- Whether discharge needs rerouting to meet local requirements
- Emergency response during a storm versus scheduled work
We charge a service call fee to come out, diagnose the problem, and quote it. That fee is applied to the work if you go ahead, and you approve the price before anything starts. Tell us what your pump is doing, or check current coupons.

Sump Pump FAQ
How long does a sump pump last?
Typically seven to ten years, though a pump running hard through wet seasons, or one dealing with iron bacteria in the groundwater, can fall short of that. If yours is past seven years and has never been tested, test it now rather than during the next storm.
How do I test my sump pump?
Pour a few gallons of water slowly into the pit until the float rises. The pump should start on its own, empty the pit, and shut off cleanly. Then go outside and confirm water is actually leaving the discharge. If it fails any part of that, have it looked at before wet weather.
Do I need a battery backup?
If your basement is finished, or if losing it would be genuinely costly, yes. The storms that produce the most groundwater are the storms that knock out power, so a pump with no backup is offline at the exact moment it matters most. If the basement is unfinished storage on a concrete floor, it is a judgment call about what is down there.
Why does my sump pump run constantly?
Common causes are a stuck or badly positioned float, a failed check valve letting discharged water fall back into the pit, discharge routed too close to the foundation so the same water keeps returning, or a pump undersized for the groundwater volume. Constant running wears out the motor quickly, so it is worth diagnosing rather than waiting.
My pump is running but the pit is not emptying. What is wrong?
That combination usually points at the discharge rather than the pump. A blocked or frozen line, or a check valve stuck closed, means the pump works and the water has nowhere to go. In winter a frozen discharge is the most likely cause, and it is urgent, because the pump is running against a closed outlet.
Can a sump pump stop sewage backing up into my basement?
No. A sump handles groundwater. Sewage surfacing at a floor drain is a sanitary sewer problem, and the defense is a backwater valve and a sound sewer lateral. Those are different systems and different fixes. See sewer cleaning and repair.
Can I discharge my sump pump into the sewer?
Many Metro Detroit municipalities prohibit it, and several communities in this region have run programs specifically to disconnect sump and footing drain connections from the sanitary sewer. Rules vary by city. If you are unsure what your house is connected to, ask us and we can confirm the requirement for your address.
How often should a sump pump be serviced?
Test it yourself each spring and again before winter. A professional check is worth scheduling annually if the basement is finished, if the pump runs frequently, or if the system includes a battery backup, since batteries degrade and need replacing on their own schedule.
Do you replace pumps during a storm?
Yes. Sump pump failure during heavy rain or snowmelt is one of the most common emergency calls we take, and it is prioritized because water is actively rising. Call (586) 296-0036 or (248) 645-2448. See emergency plumbing.
