Sump Pump Type
Submersible Sump Pump Installation
Quiet, powerful, and sealed underwater — the workhorse of most basements.
A submersible sump pump sits down inside the pit, fully sealed, with the motor underwater. It's the type we install most often in Littleton basements — quiet, powerful, and out of the way. If you have a finished basement or a real water load, this is usually the right starting point.
Because the whole unit lives in the basin, it runs quietly and handles small debris better than a pedestal pump.

How a submersible pump works
Water enters the pit, lifts a float switch, and the submerged motor drives an impeller that pushes water up the discharge line and out of the house. When the pit drops, the float shuts it off. Because it's sealed and underwater, it stays quiet and cool.
Is it right for your Littleton home?
For most homes here — especially finished basements and lots with a real water load — yes. We typically pair a cast-iron submersible with a check valve, a sealed lid, and a battery backup for a complete, dependable system.
If your pit is unusually narrow or shallow, a pedestal pump may fit better. We'll confirm during the estimate.
Best For, Pros & Cons
A clear, honest look at where this pump shines — and where another type fits better.
Best for
Most Littleton basements, finished spaces, and higher water loads
Ideal property: Finished or unfinished basements where quiet operation and capacity matter
Pros
- Runs quietly because the motor sits underwater in the pit
- Handles higher water loads and small debris well
- Takes up no floor space — fully contained in the basin
- Pairs cleanly with a sealed lid and battery backup
Cons
- Slightly harder to service since it sits in the pit
- Quality varies widely — a cast-iron unit outlasts a cheap thermoplastic one

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.
