Sump Pump Installation & Repair
SUMP PUMP INSTALLATION & REPAIR IN Reedsburg, WI.
Wisconsin's plumbing code keeps clear water out of the sanitary sewer, so a sump pump has to discharge to grade or a storm drain rather than a floor drain. Ernstmeyer Plumbing Co. LLC installs and repairs sump pumps, battery backups, and ejector pumps across Reedsburg, WI, and nearby Baraboo and Lake Delton. Where the discharge ends matters as much too.

A PUMP FAILS ON THE WORST POSSIBLE NIGHT.
That is not bad luck. A sump pump only runs hard during heavy rain or spring melt, which is exactly when a worn motor, a stuck float, or a power outage will show up. The pump that has cycled quietly for nine years is the one that gives out during the storm it was bought for.
So we look at age, cycle count, and whether there is any backup at all, not just whether the pump runs when you pour a bucket in the pit.

SUMP PUMP INSTALLATION & REPAIR
THE BACKUP MATTERS AS MUCH AS THE PUMP.
Heavy spring storms take out power and raise the water table at the same time. A primary pump on house current is useless in that exact combination, which is when most basements around here actually flood. A battery backup with its own float and its own charger is the difference between a wet floor and a dry one, and it is the upgrade homeowners regret skipping.
SPRING MELT IS THE REAL TEST HERE.
Snowpack sitting on frozen ground has nowhere to go but sideways and down along foundation walls, and it all arrives in the same week. Basements that stayed dry through a rainy summer take on water in March because the soil cannot absorb any of it. A pump sized for a rain event is not always sized for that, and we account for the difference.
EVERY SPRING TEACHES US SOMETHING ABOUT BASEMENTS.
You learn which neighborhoods sit low, which foundations weep at the cove joint, and which discharge lines freeze shut every February because they were run flat. You learn that a check valve installed backward is more common than anyone would guess. Thadd Ernstmeyer holds Wisconsin Master Plumber license 996751 and has pulled a lot of tired pumps out of a lot of pits. How old is yours?
WHAT A RELIABLE PUMP SYSTEM PROTECTS
A DRY FINISHED BASEMENT
Flooring, drywall, and everything stored down there depend on one small motor. Keeping that motor current is cheap insurance against a room that has to be rebuilt.
POWER OUTAGE PROTECTION
Storms that flood basements are the same storms that drop power lines. A battery backup runs when the grid does not, which is exactly when you need it.
NO MOLD PROBLEM LATER
Water that sits for a day starts a problem that lasts years. Keeping the pit ahead of the water table keeps humidity down and keeps mold out of the framing.
A QUIETER, STEADIER SYSTEM
An oversized pump short cycles and wears out early; an undersized one runs constantly. Matching the pump to the actual inflow makes the whole system quieter and longer lived.
CODE-COMPLIANT DISCHARGE
Routing clear water where it belongs keeps you clear of utility violations and keeps the sanitary system from being overloaded during a storm. It also keeps water away from the foundation.
CONFIDENCE DURING A STORM
Nobody should lie awake listening for a pump. A tested system with a backup and an alarm means the sound of rain stops being something you monitor.
WHAT WE INSTALL
OUR SUMP PUMP WORK
Six services cover the pit and everything connected to it. Whether the pump is dead or simply old enough to worry about, the assessment starts with how much water it actually has to move.
PRIMARY
Sump Pump Installation and Replacement
Submersible and pedestal pumps sized to the pit and the inflow, set on a solid base with a proper check valve. The discharge gets routed away from the foundation, not next to it.

BACKUP
Battery Backup Pump Systems
A second pump with its own battery and charger that takes over when power fails or the primary cannot keep up. Alarms let you know it engaged rather than leaving you to find out.

EJECTOR
Sewage and Effluent Ejector Pumps
Basement bathrooms and laundry below the sewer line need a sealed basin and an ejector pump. We install and repair them, including the vent that keeps the basin from gurgling.

REPAIRS
Pump Repair and Float Switch Service
Stuck floats, worn impellers, seized check valves, and pumps that run without moving water. Many failures are a part rather than the whole unit, and we will tell you which you have.

DISCHARGE
Discharge Line Repair and Rerouting
Lines that freeze, sag, or dump water right back against the foundation. We regrade the run, add freeze relief where it helps, and terminate it where code and common sense agree.

THE WORD ON OUR WORK
WHAT OUR CLIENTS SAY.
The calls that stay with us are the ones during a storm, when someone has water rising and a pump that will not start. Getting there before the water reaches the furnace is the kind of thing people remember for years.
★★★★★
I was thoroughly impressed by the remarkable level of care and foresight shown throughout the entire experience. Every stage reflected a deep understanding of what makes a process truly effective and enjoyable. The final outcome was exceptional and left me with complete satisfaction.
Andrew A.
★★★★★
Many plumbers to chose from, but the honest, friendly, knowledgeable approach is hard to beat. They have helped me out many times after being introduced during a 4000 sqft home build a few years back.

Common Questions
frequently asked
questions.
What homeowners ask about pits, pumps, and backups, usually right after a close call. Send anything this list leaves out through the contact page and we will answer it.
How long does a sump pump last?
Seven to 10 years is typical, less if it runs constantly. Age matters more than appearance, so if you cannot remember when it went in, it is probably time to plan a replacement. Replacing on schedule is cheaper.
How do I test my sump pump?
Pour a 5-gallon bucket of water into the pit slowly and watch. The float should rise, the pump should start, the water should drop, and the pump should shut off cleanly without chattering. Do that twice a year.
Do I really need a battery backup sump pump?
If losing the basement would be expensive, yes. Storms that overload a pit are the same storms that cut power, and a primary pump with no backup is offline exactly when it matters. It is the cheapest insurance available.
Why does my sump pump run constantly?
Either the water table is genuinely high, the float is stuck, or the check valve is letting discharged water fall back into the pit. The last one is common and simple to correct. Constant running kills pumps fast.
Where should a sump pump discharge?
Away from the foundation and onto grade or a storm connection, never into the sanitary sewer or a floor drain. 10 feet out is a reasonable minimum, further if the ground slopes back. Wisconsin code is specific here.
What is the difference between a sump pump and an ejector pump?
A sump pump moves groundwater; an ejector pump moves wastewater from fixtures below the sewer line and needs a sealed, vented basin. Ernstmeyer Plumbing Co. LLC installs both throughout Reedsburg, WI. The two are not interchangeable at all.
Why does my discharge line freeze in winter?
Flat runs hold residual water that freezes solid and blocks the next cycle. Sloping the line, shortening it, or adding a freeze-relief fitting near the house keeps the pump from deadheading against ice. That failure burns motors out.
Why have a plumber install a sump pump instead of doing it myself?
Because the discharge routing, the check valve, and the electrical all have code requirements a box store does not mention. Ernstmeyer Plumbing Co. LLC installs pumps to code around Reedsburg, WI, and stands behind the work. That matters during a storm.

HOW WE WORK
FROM RISING WATER TO A DRY PIT, HERE IS HOW.
STEP 01
Find Out How Much Water You Have
We look at how often the pump cycles, how fast the pit refills, and what the basement has done historically. Sizing anything before knowing that is a guess. Inflow drives every other decision.
STEP 02
Inspect the Pit and the Discharge
The basin, the check valve, the float clearance, and the entire discharge run all get looked at. Most pump failures we find were caused by something outside the pump itself. Replacing only the pump repeats it.
STEP 03
Recommend and Price in Writing
You get a written price covering the pump, any backup you want, and whatever the discharge needs. Options are priced side by side rather than bundled. Any work that is not included in the original estimate will be added as a separate line item.
STEP 04
Set the Pump and the Controls
The unit goes in level on a solid base with clearance for the float, and the check valve gets oriented correctly. Alarms and backup controls get mounted where you will actually hear them.
STEP 05
Route the Discharge Properly
The line gets pitched to drain, sized to the pump, and terminated well away from the foundation in a way that satisfies code. Freeze relief goes in where the run needs it. That step prevents winter callbacks.
STEP 06
Test It Under Load and Show You
We fill the pit and run the system through several cycles, including the backup on battery power. Then we show you the test procedure so you can repeat it yourself. Twice a year is enough.
