When rain starts coming down, most homeowners think about their roof and gutters. But if water collects beneath your home, your sump pump deserves attention, too.
A working sump pump helps move collected water out of a crawl space or basement. If it fails during a storm, that water can build up quickly, potentially damaging insulation, stored belongings, and building materials.
For Marin County homeowners, checking the system before heavy rain arrives is a practical way to get ahead of a messy problem.
What Does El Niño Mean for Your Home?
El Niño can influence winter weather, but it does not guarantee a wet season in Marin County. You don’t need a dramatic forecast to make storm preparation worthwhile. A few heavy storms can expose drainage problems that go unnoticed during dry weather.
If your crawl space has flooded before, water pools around your foundation, or your sump pump struggled through the last rainy season, now is a good time to have the setup checked.
How Does a Sump Pump Work?
A sump pump typically sits inside a collection basin at a low point beneath the home. As water enters the basin, a float switch activates the pump. The pump then pushes water through a discharge pipe to an appropriate drainage location.
For the system to work properly, water needs to reach the basin, the switch needs to move freely, and the discharge line needs to stay clear. The pump also needs a reliable power source.
A problem with any of those parts can leave water sitting where it shouldn’t.
Signs Your Sump Pump Needs Attention
Some problems are obvious. Others are easy to miss until the pump is under pressure.
Watch for:
Grinding, rattling, or unusual vibration while the pump runs.
Repeated starting and stopping or running continuously.
Water remaining in the basin while the pump struggles to lower it.
A stuck or obstructed float switch.
Leaks or visible damage along the discharge pipe.
Water returning toward the foundation after being pumped out.
If you moved into a home with an existing sump pump and don’t know its maintenance history, an inspection can help establish whether it is ready for the season.
Check the Pump Before the Next Storm
Start with a visual check from a dry, safely accessible location. Look for visible debris, damaged piping, and anything obstructing the float.
Follow the manufacturer’s instructions for testing your particular pump. A proper check should confirm that the pump activates, moves water out, and shuts off correctly afterward.
Avoid entering a flooded crawl space or handling electrical equipment around standing water. If access is difficult or the system’s condition is uncertain, have a professional inspect it.
Think About Backup Power
A standard electric sump pump stops working when its power supply fails. That matters during storms, when you may need the pump most.
A compatible battery backup system can provide additional protection during an outage. The right setup depends on how much water enters the space, the pump’s requirements, and how long backup operation may be needed. Backup batteries also need periodic checks and maintenance.
A Sump Pump Is Part of the Drainage Plan
A pump can help manage water that collects beneath your home, but the surrounding drainage matters, too.
Overflowing gutters, downspouts emptying beside the foundation, and blocked exterior drains can all contribute to water problems. Addressing those issues may reduce the amount of water your sump pump needs to handle.
If water keeps returning, it’s worth identifying where it comes from before simply installing a larger pump.
