Chicago homes — especially in neighborhoods near Lake Michigan, the Chicago River, and low-lying areas — are particularly susceptible to basement flooding. A properly installed sump pump is the single most effective defense against water damage. This guide covers how sump pump installation works, what it costs in Chicago, and how to choose the right system for your home.
How Sump Pump Installation Works
- Excavate the sump pit — A pit (typically 18″ diameter x 24″ deep) is dug at the lowest point of the basement floor, usually in a corner.
- Install the liner — A perforated plastic or concrete liner is placed in the pit to allow water to enter while keeping soil out.
- Install the pump — The sump pump (submersible or pedestal) is placed in the liner with the float set at the appropriate level.
- Run the discharge line — PVC pipe carries water from the pump out through the basement wall and away from the foundation (minimum 10 feet from the house).
- Add a check valve — Prevents backflow when the pump shuts off.
- Connect to power — Requires a dedicated GFCI-protected outlet. Battery backup systems add a second pump for power outage protection.
Sump Pump Installation Cost in Chicago
| Service | Typical Cost Range |
|---|---|
| Sump pump replacement (existing pit) | $300–$600 |
| New sump pump installation (new pit) | $800–$1,500 |
| Battery backup system addition | $200–$500 |
| Water-powered backup system | $300–$600 |
| Combination primary + backup | $500–$1,200 |
Submersible vs. Pedestal Sump Pumps
- Submersible pumps — Sit inside the pit under water. Quieter, more powerful, longer lifespan (10–15 years). Better for larger pits and homes with significant water issues. More expensive ($100–$400 for the unit).
- Pedestal pumps — Motor sits above the pit on a pedestal. Cheaper ($50–$200), easier to service, but noisier and less powerful. Better for smaller pits and lighter duty use.
Why Chicago Homes Need Sump Pumps
Chicago receives about 38 inches of precipitation annually, with spring storms often delivering 2–4 inches of rain in 24 hours. The city’s flat topography and clay-heavy soil mean water has nowhere to go quickly. Neighborhoods including Jefferson Park, Portage Park, Norwood Park, Dunning, Avondale, Logan Square, Bridgeport, Canaryville, and many western suburbs see basement flooding regularly. A sump pump with a battery backup is essential in these areas.
