Basements & sump pumps in Milwaukee, WI

A sump pump keeps groundwater from rising into a basement or crawl space. Most last about 7 to 10 years. Replacing an aging pump before storm season, and adding a battery backup or alarm, is far cheaper than cleaning up a flooded basement.

Basements & sump pumps services in Milwaukee

Sump pump service in Milwaukee

Urgent

A sump pump that won't run usually has a stuck float switch or a failed motor. One that runs constantly may have a bad check valve or a high water table. In cold winters, a frozen discharge line outside is a common cause of a pump that runs but doesn't empty the pit.

Local conditions

Basements & sump pumps in Milwaukee: what's different

MMSD's Deep Tunnel stores stormwater, but intense storms can still back up basements. Older homes have basement floor drains beside water heaters and laundry tubs.

Backwater valves and sump pumps help.

Testing the sump pump each spring, keeping the floor drain clear and adding a backwater valve where sewer water has come up in storms are the main protections. Older duplexes often have separate water heaters for each unit in the same basement, so one backup can affect both units' equipment.

A battery backup helps during storms that cut power.

Water and sewer in Milwaukee: Milwaukee Water Works supplies water; the Milwaukee Metropolitan Sewerage District (MMSD) handles regional wastewater.
Permits in Milwaukee: Plumbing permits are issued by the City of Milwaukee Department of Neighborhood Services.

Basements & sump pumps questions in Milwaukee

Can Milwaukee basements still flood with the Deep Tunnel?

Yes, during intense storms.

How do I test a sump pump?

Slowly pour a bucket of water into the pit. The pump should start, empty the pit and shut off. If it doesn't start, check that it's plugged in and the float can move freely.
