Sump pump service in Portland, OR
A sump pump that won't run usually has a stuck float switch or a failed motor. One that runs constantly may have a bad check valve or a high water table. In cold winters, a frozen discharge line outside is a common cause of a pump that runs but doesn't empty the pit.

Sump pump service for Portland homes
Homes with basements in the Midwest, Northeast and Mountain West often have a perimeter drain feeding a sump pit. Spring snowmelt, heavy storms and high water tables are when pumps get tested, and a failure during either one can flood a finished basement fast.

Local conditions
Sump pump service in Portland: what's different
Portland's long rainy season, from fall through spring, saturates soil and tests sump pumps and foundation drains in older basements. Many basements in Laurelhurst and Irvington were finished long after the house was built, sometimes over an old pit with a pump that is rarely tested.
A plumber tests the pump and float, checks the discharge line and check valve, and recommends replacing pumps more than seven to ten years old. A battery backup helps during winter storms and the occasional ice storm that knocks out power.
