What Your Sump Pump Actually Does (And Why It Matters)

If you’ve ever wondered what that weird pit in your basement is for, you’re not alone. That’s your sump pit, and if water starts collecting under your home (from heavy rain, melting snow, or rising groundwater), the sump pump’s job is to pump it away from your foundation before it causes damage.

A working sump pump can protect your home from:

• Costly water damage
• Mold and mildew growth
• Foundation cracks
• Ruined flooring and drywall

But when that pump is dead, clogged, or incorrectly installed, water wins. And water always finds a way. That’s why it’s so important to test your system, keep it maintained, and replace it before disaster strikes, not after.

Common Sump Pump Issues We Fix All the Time

You’d be surprised how often people think their pump is fine—until it’s not. The good news? We’ve seen it all and know exactly what to look for. Whether it’s a worn-out float switch or a motor that gave up mid-storm, we’ll figure it out and get things back on track.

Here are some common problems we fix:

• Sump pump won’t turn on
• Runs constantly, even when it’s dry
• Strange noises during operation
• Water collecting around the pit
• Backup battery isn’t working
• System wasn’t installed correctly

Sometimes it’s a quick fix. Other times, it makes more sense to replace the whole unit—especially if yours is over 10 years old or struggling to keep up. We’ll walk you through the options and give you one clear price before we do anything.
