Basements & sump pumps in Cincinnati, OH

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 Cincinnati

Sump pump service

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 Cincinnati: what's different

Low areas near the Ohio River can see backups during river flooding. Backwater valves and sump pumps help keep basements dry.

Older basements often have floor drains tied directly to the main.

Hilly lots mean many Cincinnati homes have walk-out basements where groundwater and storm runoff collect. A working sump pump handles groundwater; a backwater valve stops sewer water from coming up through the floor drain. MSD has programs to help with backups in flood-prone areas, and testing the pump each spring prevents most surprises.

Basements & sump pumps questions in Cincinnati

Do Cincinnati basements need backwater valves?

In flood-prone areas, they help prevent sewer backups.

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.
