About Sump Pump Repair Guys in Janesville
We repair sump pumps and nothing else. No waterproofing upsell, no membership plan. You get a diagnosis, a written price, and a full-cycle test before we leave.
People are often told their pump is undersized when the real problem is the hole it sits in. There is a minimum size, and it is easy to measure.
The numbers your pit has to meet
State code sets a floor on sump size, and no manufacturer requirement below it counts either. A basin under these dimensions makes any pump fitted into it cycle too often.
- Measure
Short cycling has a cause
If your pump starts every thirty seconds in ordinary weather, measure the basin before anyone sells you a bigger motor.
- Roots
The usual cause of a backup
The city puts roots in the sewer main or service lateral at the top of the list, ahead of grease, rags and other objects that should never be there.
- Grease
Jar it, then bin it
Pouring cooking grease down the sink is named directly. It cools, coats the pipe, and gives roots and rags something to hold onto.
- Never flush
Wipes, nappies, paper towels
All listed as backup causes. They pass your own trap easily and then stop at the first root intrusion downstream.
One pipe gets treated. The other does not.
The city is blunt about this. Water in a storm sewer is never treated. It flows to local waterways carrying whatever it picked up, which is why only rain should ever be in it.
-
It cuts both ways
Clear water in the sanitary sewer wastes treatment capacity and causes backups. Dirty water in the storm sewer goes straight to the river. Each pipe has one job.
-
Call the utility, not just a plumber
Janesville runs a daytime line and a separate 24 hour emergency number for sewer backups. Reporting it lets them check the main before you spend anything.
-
Repeat blockages point at roots
If the same stretch clears and then blocks again within months, something is growing into the pipe. Rodding treats the symptom, a camera finds the joint.
-
Protecting the Rock River is the point
The utility states water quality in the river as part of its purpose, which is the reason behind most of the rules on this page.
What we repair
- 01
Float switch
The most common failure, and the first casualty of a basin that is too small.
- 02
Check valve
Failed valves drop the discharge column back into the pit seconds after shutoff.
- 03
Impeller and motor
Grinding, humming or tripping. We test under load before recommending replacement.
- 04
Undersized basins
Measuring the pit against the minimum, and replacing it where the numbers explain the short cycling.
- 05
Discharge line and outlet
Blocked, crushed, frozen, or ending where the water simply returns to the footing drains.
- 06
Backup systems
Battery load testing and changeover checks, because storms take the power out.

Janesville sump pump questions, answered
How big does a sump pit have to be?
State code sets a minimum of 16 inches across the top, 14 inches across the bottom and 22 inches deep, and never smaller than the pump manufacturer requires. Anything less makes the pump cycle far more often than it should.
My pump starts every thirty seconds. Is it failing?
Measure the basin first. Short cycling in ordinary weather usually means too little volume between the on and off levels, or a check valve letting the column fall back. A bigger motor makes both worse.
What causes most sewer backups here?
Roots in the sewer main or service lateral, according to the city. Grease, rags and other foreign objects account for much of the rest, and they tend to collect at the point where roots have already got in.
Does it matter what I put down the storm drain?
Very much. Water in a storm sewer is never treated and flows to local waterways carrying whatever it collected. Only rain and clean groundwater should ever go into it.
Should I report a backup to the city?
Yes. There is a daytime utility line and a separate 24 hour emergency number for evenings, weekends and holidays. Reporting it means the main gets checked before you commit to work on your own lateral.
How fast can someone come out?
Same day across most of Rock County, and after hours when water is already coming in. Most parts-level repairs finish in the same visit.
Measure the pit before you replace the pump.
Emergency repair, diagnostics, pit and valve testing, or a dry-weather inspection. Serving Janesville and all of Rock County.
