How the job is handled
Float switches cause many failures: they jam against the pit wall or the cord tangles. Clogged intake screens, a stuck check valve or a frozen discharge line outdoors are next on the list. We test each part in sequence, clean the pit, and replace the pump when the motor itself has worn out.
We also check the outlet and circuit. A pump on a shared circuit with a freezer or a ground-fault outlet that has tripped can stop without warning.

Local card: Whitby houses
Discharge pipes that run across a Whitby lawn can freeze solid in January, forcing water back into the pit. A freeze-protection fitting near the house lets water escape if the line ices up.
The visit, in order
- Power and outlet checked
- Float, intake and check valve tested
- Pit cleaned and discharge checked outside
- Repair or replacement and fill test
Ring us when
Call as soon as the pump stops or acts strangely, especially before a storm forecast.
Common questions
Why does my pump run when it is not raining?
Groundwater can stay high for days after rain or thaw. A pump that runs constantly with no water entering may have a check valve problem.
Should I keep a spare pump?
For basements with frequent pump activity, a spare or a backup unit is good insurance.
