Our Sump Pump Installation & Repair Process

01

Assessment

We evaluate your existing system (or determine if a new pit needs to be dug), check discharge routing, and identify the right pump capacity for your water table.

02

Pump Selection

We recommend the appropriate primary pump HP, backup system type (battery, water-powered), and smart monitoring options.

03

Installation

The pump is installed in the pit, discharge pipe is connected and routed to a proper discharge point, and check valves are installed.

04

Testing

The system is tested by adding water to the pit, confirming the pump activates at the proper level, runs correctly, and discharges water away from the foundation.

Sump Pump Installation & Repair FAQ for Seattle Homeowners

How often should Seattle homeowners get sump pump installation & repair?
Given Seattle's 160+ rain days per year averaging 38 inches, most homeowners benefit from sump pump installation & repair at least once a year. Year-round moss and algae on roofs and driveways often makes spring or fall the optimal time to schedule service.
What home types in Seattle most need sump pump installation & repair?
Craftsman bungalows and Mid-century ranches are the most common home types in Seattle and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How long do sump pumps last?
Most sump pumps last 7–10 years with moderate use. In areas with high water tables or frequent cycling, 5–7 years is more typical. Replace proactively rather than waiting for failure.
Do I need a backup sump pump?
A battery backup is strongly recommended. Most basement flooding events happen during storms — exactly when power outages also occur, disabling your primary pump. A backup provides critical protection.
Where should sump pump water discharge?
Discharge should be piped at least 10 feet from the foundation, ideally to a dry well, drainage ditch, or storm drain. Discharging too close to the house just recirculates the same water back into the pit.
My sump pump is running constantly — is that normal?
Continuous running indicates either a very high water table (may be normal in spring), a stuck float switch, a failed check valve allowing water to drain back in, or an undersized pump.
