Sump Pump Repair in Wauwatosa, WI
A sump pump is the last line of defense between your basement and the water that builds up under and around your foundation. When it stops working — or runs nonstop, or cycles constantly, or fails the moment a storm hits — your basement can flood within hours. We repair and replace sump pumps across Wauwatosa and Greater Milwaukee, from a stuck float switch to a full new installation with a battery backup. We'll test the pump, the switch, the check valve, and the discharge line, tell you exactly what's wrong, and give you a clear, written estimate before any work starts.
Proud to Serve Wauwatosa & Greater Milwaukee
We help homeowners across Wauwatosa and the surrounding Milwaukee County and Waukesha County communities.
What's Included
Pump diagnosis & repair
Pumps that won't turn on, run nonstop, cycle constantly, or make noise — tested and repaired or replaced.
Float switches & check valves
Stuck, misadjusted, or failed float switches and check valves that let water cycle back in.
Discharge lines
Frozen, blocked, or poorly routed discharge lines cleared and corrected so water moves away from the house.
Battery backup systems
Backup pumps and battery systems that keep your basement dry when the power goes out in a storm.
New installation
New sump pump and basin installation, including homes still draining through an old Palmer valve in the floor drain.
Why This Happens in Wauwatosa
In Wauwatosa and the surrounding Milwaukee County and Waukesha County communities, sump pumps work hard. The heavy glacial clay soil under this area holds water against basement walls instead of draining freely, so a lot of groundwater ends up in the sump pit — especially in spring when snowmelt saturates the ground and during intense summer thunderstorms. The area has seen severe flooding from storms like those in July 2010 and August 2025, and those events push pumps past their limits. Winters are long and the ground freezes several feet deep, so a discharge line that exits too close to the house or isn't sloped right can freeze solid and force water back in. Many homes here date from the 1910s to the 1950s, and some older ones still drain through a Palmer valve in the floor drain rather than a sump pump — a setup that often can't keep up with today's water table.
How to Help Prevent It
- Test your sump pump before spring thaw and again before storm season — pour a bucket of water in the pit and confirm it kicks on and empties.
- Make sure the discharge line exits well away from the foundation (at least 10–15 feet) and is sloped so it can't pool or freeze.
- Check that the discharge line isn't blocked, crushed, or frozen in winter, and consider a buried or insulated line if it freezes regularly.
- Clean the sump pit of debris so the float switch can move freely and the pump intake doesn't clog.
- Install a battery backup so the pump still runs when the power goes out during a storm — exactly when you need it most.
Cost Guide
Every home is different, so we price every job after a free inspection. Here's what shapes the cost.
| Repair type | Typical price | What affects cost |
|---|---|---|
| Float switch / check valve repair | Free quote after inspection | Parts are modest; cost depends on access to the pit and whether the discharge line needs rerouting. |
| Sump pump replacement | Free quote after inspection | Driven by pump horsepower, brand, and whether the basin or discharge line also needs work. |
| Battery backup system | Free quote after inspection | Depends on backup pump size, battery capacity, and existing pit wiring. |
| New sump pump installation | Free quote after inspection | Higher when we're cutting a pit, running a discharge line through the foundation, or replacing an old Palmer valve setup. |

Sump Pump Repair FAQ
Why does my sump pump run nonstop?
Usually it's one of three things: a lot of groundwater getting in (common here in spring), a float switch that's stuck or misadjusted, or a check valve that's failing and letting water cycle back into the pit. A blocked or frozen discharge line can also cause it. We test each one to find the cause and tell you whether it's a repair or a replacement.
Should I repair or replace my sump pump?
If the pump is relatively new and the problem is a float switch, check valve, or discharge line, a repair usually makes sense. If the pump is older, has failed during a storm, or is undersized for your home's water load, replacement is often the better long-term call. We'll give you an honest read on which way to go and why.
Do I need a battery backup?
If your basement is finished or you store anything of value down there, yes. Power outages and storms tend to arrive together, and that's exactly when your pump matters most. A battery backup keeps the pump running when the power is out, and many systems add a second pump for extra capacity.
My older home has a Palmer valve, not a sump pump — what should I do?
Some older Wauwatosa-area homes still drain through a Palmer valve in the floor drain instead of a sump pump. That setup often can't keep up with today's water table, especially in storms. We can install a proper sump pump and basin and route a discharge line away from the foundation, which gives you real protection instead of relying on an old floor-drain valve.
