What this job involves
Sumps quit in a handful of predictable ways: the float snags on the crock wall, the switch wears out, gravel jams the impeller, the check valve sticks, or the motor simply gives up. Most of those announce themselves well before the flood. A repair visit begins by filling the crock and watching closely what the pump does, and does not, do.
How the job goes
- Unplug the pump and lift it to inspect the intake screen.
- Check the float travels freely and the switch clicks cleanly.
- Test the check valve by watching for backflow at shut-off.
- Shovel silt and gravel out of the crock floor.
- Reset, refill, and observe several cycles before packing up.
Warning signs on your pipes
- The motor hums but the level stays put.
- The pump runs with no water arriving.
- Water stands higher in the crock than it normally does.
- The breaker trips as the pump starts.
- Rattling or grinding during a cycle.
From the job notes
Many crocks we see in Oakville sit in unfinished corners where the float tether drifts and wedges against the liner.
Many crocks we see in Oakville sit in unfinished corners where the float tether drifts and wedges against the liner. A vertical float switch cures that in narrow pits. If the motor itself is the casualty, replacement nearly always beats repair, and we say so plainly.
We also look at the outside end. A crushed or frozen discharge line will cook a healthy pump in one storm, so a repair that ignores the outdoor pipe is only half done.
What comes off the truck
| Tool or part | What it does on the job |
|---|---|
| Discharge extension | Throws water clear of the foundation instead of back into the weeping tile |
| Check valve | Stops the discharge column from dropping back into the pit |
Questions we hear
Repair, or new pump?
Switches, floats and check valves are worth fixing. A burnt-out motor generally means a new pump.
Why won’t mine stop running?
Usually one of three: a high water table, a switch welded on, or a check valve letting the discharge column slump back. Each gets tested.
