Sump Pump Float Switch Repair
The most common reason a pump runs nonstop — or won't run at all.
The float switch is the most common point of failure on a sump pump. When it sticks, the pump either runs constantly (burning out the motor) or never turns on at all (letting the pit overflow). Littleton Sump Pump Pros repairs and replaces float switches across the Littleton area.
It's a small part with an outsized job — telling the pump when to run.

Signs of a float switch problem
- Pump runs constantly even when the pit is low
- Pump never turns on while water rises
- Pump short-cycles on and off rapidly
- The float is visibly tangled, jammed against the pit wall, or waterlogged
- Debris in the pit is interfering with float movement
Float switch types we service
We work with tethered, vertical, and electronic float switches. Sometimes the fix is freeing a jammed float and cleaning the pit; sometimes the switch itself is worn and needs replacement. We'll match the right switch to your pump and pit size.
A pit that's too narrow for a tethered float is a frequent culprit — switching to a vertical float often solves chronic sticking.

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.
