Gresham
The Gresham angle on sump pumps
Multnomah County County's water table writes the rules here. Crawl-space foundations stay damp through the long wet season. Add aging pipe stock: Gresham's older homes still run galvanized and cast-iron systems that corrode from the inside and fail with little warning., and the pump is not an accessory; it is infrastructure.
In Gresham, sump pumps earn their keep against local water. Crawl-space foundations stay damp through the long wet season. Newer subdivisions can have immature grading that pools stormwater at foundations. Aging pipe stock: Gresham's older homes still run galvanized and cast-iron systems that corrode from the inside and fail with little warning. — that is the arithmetic that makes a working pump non-negotiable.

Sump pump warning signs
A pump that cannot keep up is barely better than no pump. Watch for these.
- The pump runs constantly or never turns on during heavy rain.
- Water pooling around the sump pit or on the basement floor.
- Strange noises — grinding, rattling, or gurgling from the pit.
- The pump is more than 7–10 years old.
- No battery backup — a single power outage during a storm means no protection.
What the pro does on a sump call
Expect the pro to think in systems — because floods do not care which part failed.
- Testing of the existing pump under load — not just a float wiggle.
- Diagnosis: failed switch, burned motor, stuck float, or discharge problem.
- Replacement with a correctly sized pump for the pit and inflow.
- Check-valve inspection and replacement so water does not flow back.
- Battery backup options for homes where outages coincide with storms.
- Discharge-line check: clear routing that moves water away from the foundation.
Test your pump today
The single most valuable thing you can do is test the pump before you need it. These safe checks take minutes.
Safe to do now
- Pour a bucket of water into the pit periodically to confirm the pump cycles on and off.
- Keep the pit clear of debris that can jam the float switch.
- Check the discharge outlet outside — it should drain well away from the foundation.
- Test the battery backup monthly and replace batteries on schedule.
Stop — call a pro
- A pump that trips the breaker or smells like burning — unplug it and call a pro.
- Extending or rerouting the discharge line without checking local code.
- Sizing and installing a new pump yourself — an undersized pump fails when you need it most.
- Ignoring a pump that runs constantly — it may be undersized or the check valve may have failed.
The process, step by step
From the first test to a pump you can trust in a storm — how it unfolds.
System test: the pro fills the pit and watches the pump cycle — switch action, pump-out rate, and shutoff.
Find the failure: float switch, check valve, discharge line, or the pump itself.
Repair or replace: stuck switches and clogged lines get fixed; failed pumps get swapped for a correctly sized unit.
Backup and discharge check: battery backup tested, discharge line cleared, and the outlet positioned to drain away from the foundation.
Sizing and backup: what matters
Horsepower, switch type, and battery backup are the three decisions that matter. Understand them.
- Repair versus full pump replacement.
- Pump type and capacity — pedestal versus submersible, and horsepower sizing.
- Battery backup system — add-on unit versus integrated.
- Discharge line work — length, freeze protection, and routing away from the house.
- Whether a new pit needs to be dug for a first-time installation.
