Sump Pump Maintenance Checklist
What to check, and how often, to keep the system storm-ready.
Quick answer
A good sump pump maintenance checklist comes down to a few quarterly checks and one thorough annual service — ideally before spring snowmelt. Stay on this rhythm and your pump will be ready when the water arrives, instead of failing when you need it most.
Print this, or save it. Here's the routine.
- Local Littleton Service
- Professional Installation
- Clear, Upfront Estimates
- Battery Backup Options
- Careful, Clean Workmanship
- Emergency Help Available
Every few months
- Pour a bucket of water in to confirm the pump activates and shuts off
- Check the float moves freely and isn't tangled
- Listen for unusual grinding or humming
- Confirm water exits the discharge outside, away from the foundation
Once a year (before storm season)
- Clean silt and debris from the pit and intake screen
- Inspect and test the check valve
- Test the battery backup and check the battery's age (replace every 3–5 years)
- Inspect the discharge line for clogs and freeze damage
- Confirm the discharge still terminates well away from the house
- Verify the pump is level and seated correctly in the pit

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.
