A properly functioning sump pump is your first line of defense against water intrusion.

Frequently Asked Questions
How often should I test my sump pump?
We recommend testing your sump pump every 3-4 months by pouring water into the pit to ensure it activates properly. Test more frequently during rainy season.
Do I need a battery backup sump pump?
In the Pacific Northwest, power outages often coincide with heavy storms—exactly when you need your pump most. A battery backup provides peace of mind during outages.
How long do sump pumps last?
Most sump pumps last 7-10 years with proper maintenance. Heavy usage or poor water quality can shorten lifespan.
What size sump pump do I need?
Pump size depends on your home's water table, basement size, and drainage conditions. Our technicians can assess your needs and recommend the right pump.
Why is my sump pump running constantly?
Continuous running may indicate a stuck float switch, undersized pump, high water table, or plumbing issue. Call us for a diagnosis before the motor burns out.
