In Seattle, your sump pump is one of the few things standing between heavy winter rain and a flooded basement. When it fails, you usually find out the hard way. All Phase Plumbing installs, repairs, and replaces sump pumps to keep your basement and crawl space dry year-round.

Whether your existing pump is humming but not pumping, cycling constantly, or it's simply time for an upgrade, our licensed plumbers will get you a system you can rely on.

Call (206) 772-6077 to schedule sump pump service.

Sump Pump Repair

Common sump pump problems we fix:

Pump runs constantly or short-cycles
Pump hums but doesn't pump water
Float switch stuck or damaged
Discharge line frozen or blocked
Power or wiring issues
Loud grinding or rattling noises

Sump Pump Replacement

Most sump pumps last 7–10 years. If yours is older, struggling, or failed during a recent storm, replacement is usually more cost-effective than chasing repairs. We'll size the new pump to your basin and discharge run, and offer battery-backup options so a power outage doesn't equal a flooded basement.

Sump Pump Installation

New installations include:

Basin and pit installation if needed
Primary submersible or pedestal pump
Optional battery-backup secondary pump
Check valve and discharge plumbing
Outdoor termination away from the foundation

Schedule Sump Pump Service

Don't wait for the next big storm to find out your pump can't keep up. Call (206) 772-6077 for a sump pump check, repair, or new install.
