A sump pump only matters on the day it has to work — which in western Oregon means the atmospheric-river stretch of the rainy season, when the water table rises and the pit fills for days at a time. The maintenance that keeps it ready takes about twenty minutes a season, and the core of it is embarrassingly simple: pour water in the pit and watch what happens.
Restoration crews meet the alternative every winter: a finished basement, a quiet pump that seized months earlier, and a storm that found out. The routine below is what we'd do in our own homes.
How do I test a sump pump?
Pour a bucket of water into the pit — enough to raise the float. A healthy pump kicks on within seconds, evacuates the water quickly, and shuts off without short-cycling or grinding. That single test exercises the float switch, the motor, and the discharge path together, which is why it beats any amount of visual inspection.
While you're there: unplug the pump and clear the pit of sediment and debris (float switches jam on gravel and children's toys with equal enthusiasm), confirm the check valve on the discharge line is oriented correctly and holding (water shouldn't pour back into the pit when the pump stops), and follow the discharge line outside to make sure it daylights well away from the foundation and isn't crushed, clogged, or — in a cold snap — frozen solid.
How often, and when, should I do this?
Test quarterly, with two non-negotiable dates: early fall before the Pacific Northwest rainy season arrives in earnest, and midwinter ahead of the biggest storm stretches. Pumps that sat idle all summer are exactly the ones that seize when October delivers the first real load.
The seasonal checklist:
- Bucket test the float and pump (every quarter).
- Clean the pit and intake screen (fall, and after any sediment-heavy event).
- Verify the check valve holds and the discharge daylights clear of the foundation (fall).
- Confirm the outlet is GFCI-protected and the cord isn't sharing an overloaded circuit (annually).
- Test the battery backup if you have one, and replace its battery on the manufacturer's schedule (typically every few years).
Do I need a battery backup sump pump?
Ask one question: what happens here during a storm that takes the power out? In much of Oregon the honest answer is that the pump dies at the exact moment inflow peaks — the storm that floods your pit is the storm that drops your line. A battery backup (or water-powered backup where municipal pressure allows) exists purely for that hour, and for finished basements it's the difference between an inconvenience and an insurance claim.
The other failure the backup covers is the primary pump itself — floats stick and motors quit, usually mid-storm, because that's when they're working hardest. If your basement is finished or stores anything you'd grieve, run a primary with a backup and test both. If it's a bare crawl-height space that's seen a century of moisture, a reliable primary plus quarterly tests may honestly be enough.
Questions we hear about this
How long do sump pumps last?
Roughly a decade is the common design life, but duty cycle rules everything — a pump in a high-water-table pit works harder and ages faster. Grinding, short-cycling, rust, or hesitation on the bucket test are replace-now signals regardless of age.
My sump pump runs constantly. Is that normal?
During a Pacific storm stretch, frequent cycling can be normal. Constant running in dry weather usually means a stuck float, a failed check valve recycling the same water, or genuine groundwater intrusion — the first two are quick fixes, the third is a drainage conversation worth having before winter.
The pump failed and the basement flooded. Now what?
Kill power to affected circuits if safe, don't wade into standing water, and call for extraction fast — basement floods migrate into framing and drywall within hours. Our flooded-basement first hour playbook walks the immediate steps, and Summit's line is answered 24/7.
