Sump Pump Type
Combination Sump Pump Systems
Primary plus backup, engineered to work together in one pit.
A combination sump pump system puts a primary pump and a battery backup in the same pit, engineered to work as one. The primary handles everyday water; the backup takes over automatically during a power outage or if the primary can't keep up. For finished basements, it's the most dependable setup we install.
If a failure would ruin your lower level, this is the protection to ask about.

How a combination system works
Both pumps share the pit. The primary runs on household power for normal water removal. The controller monitors for power loss or rising water and switches to the battery-powered backup automatically, sounding an alarm so you know it engaged.
Who should consider one
Finished basements, homes with a high water table, and anyone who has lost power during a storm. The combination removes the single biggest risk — the primary pump having nothing to run on when the power's out.
We size both pumps to your water load and confirm the pit can house the pair.

What Homeowners Say
A few illustrative examples of the basement-water problems we help solve across the Littleton area.
Our sump pump quit during a spring storm and the basement started taking on water. They walked us through what to do, got out quickly, and replaced the pump with a backup. Dry ever since.
We were finishing our basement and wanted to do it right. They sized a system for our clay soil, added a battery backup, and ran the discharge well away from the house. Clear estimate, clean work.
The discharge line kept freezing every winter. They re-routed it below the frost line and the problem is gone. Friendly, local, and they explained everything.
Our older home always smelled musty downstairs. They found water wicking up where the wall meets the floor, put in a proper pit and pump, and the smell is finally gone.
I got three quotes, and theirs was the only one that actually explained what I was paying for. No pressure, tidy work, and they tested everything before they left.
The pump was cycling every couple of minutes and driving us crazy. Turned out the pit was undersized. They fixed it right and showed me how to test it myself.
