Pump doesn't turn on when the pit fills. Here's what to do about sump pump problems in San Francisco Bay Area — including the local factors that change the advice.
Do this right now
Test it right now
Pour a bucket of water into the pit. The float should rise and the pump should kick on, drain the pit, and shut off. If any step fails, you found your problem.
Check power
Make sure it's plugged in, the outlet works, and the breaker hasn't tripped. Storms trip breakers at the worst moment.
Free the float
The float switch jams on pit walls and debris more than anything else. Clear the pit and make sure the float moves freely.
Check the discharge line
Follow the pipe outside — it should be clear and directing water away from the foundation. A frozen or clogged discharge line makes the pump run forever.
Call for service or backup
Call (844) 699-1165. A pro can replace a dead pump in one visit — and ask about battery backup systems, because pumps love failing during power outages.
