Plenty of Granite Bay homes, especially those on sloped lots or with crawlspaces that took on water in past winters, rely on a sump pump. Because they sit dry for six months, the most common failure is simple: nobody knows it’s broken until it’s needed.
The 5-minute fall test
- Check power. Make sure the pump is plugged in and the outlet works. GFCI outlets trip and stay tripped unnoticed. Press reset.
- Look in the pit. Remove the lid and clear out debris, silt, or rodent nesting material. Anything that can jam the float or clog the intake will.
- Add water. Slowly pour a bucket or run a hose into the pit until the float rises. The pump should kick on, empty the pit, and shut off on its own.
- Follow the discharge. Go outside and confirm water is actually coming out where it should. A crushed, clogged, or disconnected discharge line means the pump just recirculates water back into the ground.
- Listen. Grinding, rattling, or a pump that runs but moves little water points to a worn impeller or failing motor.
Tip: make sure the discharge outlet isn’t right next to the house. If the pumped water lands near the foundation, it soaks back in and the pump just cycles the same water all night.
The most common sump pump failures
- Stuck float switch. The float gets hung up on the pit wall or cord and never triggers. It’s the most frequent issue and often an easy fix.
- Clogged or frozen discharge line. Roots, silt, or a collapsed buried line block the outlet.
- Missing or failed check valve. Without it, water in the discharge pipe falls back into the pit and the pump short-cycles.
- Power outage. Winter storms and power outages go together. A pump with no battery backup does nothing when the power is out.
- Old age. Many pumps last roughly 7–10 years. If yours is older and struggling, replacing it before the season is cheap insurance.
Should you add a battery backup?
If your crawlspace floods without the pump, a battery backup or secondary pump is worth considering. The worst storms are exactly when outages happen. It’s one of the few upgrades that only matters on the one night it matters most.
Is a sump pump the right fix at all?
Sometimes a pump is treating a symptom. If water reaches the crawlspace because downspouts dump at the foundation or the soil slopes toward the house, fixing that first can mean the pump barely runs. See downspout drainage, grading & slope, and water in the crawlspace.
