If your sump basin is filling and the pump is silent, call now. The line is answered 24/7, and the first thing to do is keep yourself and your belongings out of the water. Our plumbers handle pump failures at night and on weekends, and same-day appointments are available when the schedule allows.
Most sump failures come down to a few causes: a stuck float, a clogged intake, a failed check valve, a dead motor or a lost power supply. Some of these take minutes to fix. Others mean a new pump, and we will say which one it is before any work starts.
Basin Rising Right Now? Do These Things First
Water that has reached the top third of the basin needs attention today. These steps protect you while the plumber is on the way.
- Stay out of standing water.If water covers the floor near outlets, a power strip or the panel, do not walk through it. Electricity and wet concrete are a bad mix.
- Check the power the safe way.If the cord is dry and you can reach the outlet without wading, look for a tripped GFCI button or breaker. Reset it once. If it trips again, leave it off and tell us.
- Lift valuables and clear the floor.Move boxes, stored paper and electronics up onto shelves or tables. Pull up area rugs so water does not wick into them.
- Look at the float and the discharge pipe.With the lid off and the pump unplugged, check whether the float arm is stuck against the wall. Do not reach into the basin while the pump is plugged in.
- Call and describe what you see.Tell the plumber whether the pump hums, runs without moving water, or makes no sound at all. That helps us arrive with the right parts.
If water is entering fast from a burst pipe rather than the ground, shut off the main water valve and read our page on burst pipe repair while you wait.
Signs Your Sump Pump Is Failing
A pump rarely dies without warning. Most give one or more of these signals, and a thaw or a heavy storm is when the weak ones quit.
Runs constantly.
A pump that never shuts off may have a stuck float, a failed check valve or a basin too small for the water coming in. Constant running also wears out the motor.
Cycles on and off in seconds.
Short cycling usually means water is flowing back down the discharge pipe because the check valve is bad. The pump pushes the same water out again and again.
Loud grinding or rattling.
Noise often means debris in the impeller or worn bearings. A rattle can also come from a loose discharge pipe.
Basin water keeps rising.
If the pump runs and the level still climbs, the intake may be clogged or the pump is too weak for the load.
Hums but moves no water.
A humming pump with no discharge can have a seized impeller or a frozen or blocked outside pipe.
Nothing happens at all.
No sound and no movement points to power loss, a dead motor or a float that is not switching on.
Pump quiet and basin rising?
Call now. We answer 24/7 and can often schedule a same-day visit for a failed sump pump.
Sump Pump Problems and the Usual Fix
This table shows what we find most often and what the repair usually involves.
| What you notice | Likely cause | Typical repair |
|---|---|---|
| Pump runs nonstop | Stuck float or failed check valve | Free or replace the float switch, or replace the check valve. |
| Pump hums, no flow | Seized impeller or blocked discharge | Clear the intake, thaw or clear the outside pipe, or replace the pump. |
| Short, rapid cycles | Backflow through a bad check valve | Install a new check valve and confirm the pipe slope. |
| No power, no sound | Tripped GFCI, dead motor or lost power | Reset once, test the outlet, or replace the pump. |
| Loud grinding | Debris or worn bearings | Clean the basin and intake, or replace the pump. |
| Water rises in a storm | Pump undersized or no backup | Size a stronger pump and add a battery backup. |
A plumber confirms the cause on site, so treat this table as a guide and not a diagnosis.
A basin that stays wet after the pump runs can also point to a drainage problem outside the home. Our basement waterproofing page explains when the pump is only part of the answer.
Where the Water Goes After the Pump Matters in Rosemount
Discharge rules vary from city to city, and we do not quote a Rosemount rule here because the city's own pages do not spell one out. A common restriction in many places is that a sump pump may not connect to the sanitary sewer. Before you connect or reroute a discharge line, confirm the requirement with the city Building Permits and Inspections office at 651-322-2024.
The city's 2007 sanitary sewer plan lists sump pumps and roof drains as inflow into the sanitary system. That is a planning statement and not an ordinance, but it shows why the city cares where this water ends up. Clean groundwater in the sewer takes up capacity that the city and the Metropolitan Council pay to move and treat.
Twin Puddles Park on Dodd Boulevard is named for the lack of storm sewer in that neighborhood, according to the city. If your home sits in an area like that, a discharge line that dumps near the foundation can send water straight back to the basin. We plan the outlet so water travels away from the house and does not freeze in the pipe.

Repair the Pump or Replace It
A pump is a wear item. Here is how we think about the choice.
Repair makes sense when.
- The problem is a stuck float, a clogged intake or a bad check valve.
- The pump is quiet and moves water well once cleared.
- The motor is not overheating or tripping the breaker.
Replace makes sense when.
- The motor hums but will not turn, or trips the breaker.
- The pump runs constantly and the basin still rises.
- It is old enough that another failure in the next storm is likely.
Replacing in the same visit usually costs less than a repair followed by a second emergency call. We tell you which path fits before we start.
How a Sump Pump Visit Goes
The visit follows the same order every time so nothing is missed.
Find out why it stopped.
We check power, the float, the intake and the pump body. We also look at the basin size and the pipe leaving it.
Clear and test.
We clear debris, pour water into the basin and watch the full cycle. A pump that starts and stops cleanly passes.
Check the check valve.
We confirm the valve holds water in the pipe and does not let it fall back. A failed valve is a common reason a good pump still struggles.
Review the discharge line.
We trace the pipe outside, look for kinks or freeze risk, and check where the water lands.
Explain the options.
You hear the repair choices and the price before work starts. Nothing is replaced without your approval.
Battery Backup and Check Valves: The Two Upgrades That Pay Off
Storms often knock out power at the same moment the pump is working hardest. A battery backup pump sits in the basin beside the main pump and takes over if power fails or the main pump quits. It does not run forever, so it buys time and does not replace the grid.
A good check valve keeps discharged water from flowing back into the basin. It is cheap compared with a pump and it saves wear on the motor. We install them with a union fitting so they can be replaced without cutting pipe later.
What Changes the Price of Sump Pump Work
We give a clear price before work starts. These are the things that move it.
Ask your homeowner policy provider whether water from a failed sump pump is covered, because many policies treat it differently from other leaks. We can describe what we found in plain language for your claim.
Sump pump questions from Rosemount homeowners
Yes. The line is answered 24/7. If the basin is rising, stay out of any standing water, check that the cord is dry before touching it, and call. We schedule same-day visits when available.
There is no single number. A pump that runs often in a wet spot wears out sooner than one that only works in spring. If yours is failing or noisy, replacement is often cheaper than repeated repairs.
That is a common restriction in many cities, and we cannot confirm a Rosemount rule. Call the city Building Permits and Inspections office before you connect anything.
If you have had water in the basement during a power outage, yes. The backup runs only for a limited time, so it is a bridge and not a full replacement for grid power.
A stuck float, a failed check valve or high groundwater can all cause it. A plumber can tell which by watching the pump cycle.
A frozen pipe can leave the pump humming with no flow. Do not pour boiling water on it. Turn the pump off and call so we can clear it and fix the cause.
We handle the plumbing side, including pumps, drains and supply leaks. Foundation cracks and exterior waterproofing are often a foundation contractor's work, and we will tell you if that is what you need.
