Why Is My Sump Pump Constantly Running?

If your San Angelo sump pump seems like it never stops, you’re not alone — it’s a common concern for homeowners in the area. A pump that runs nonstop may just be doing its job. Although, it might be signaling a bigger issue that needs attention. At Lone Star Contracting, we’re here to help you understand the difference so you can protect your home and plumbing system.

Let’s break down the possible reasons why your pump runs continuously, when it’s normal and when it’s time to take action.

Is It Normal For A Sump Pump To Run All Day?

That depends on the situation. In some cases — especially after heavy rainfall — it’s normal for a sump pump to run all day. Your pump might be working overtime to keep groundwater from flooding your basement. However, if the weather is dry and your pump is still constantly running, it’s worth investigating.

A few situations where constant operation is expected include:

• Ongoing wet conditions or high groundwater levels
• A sump pit that fills quickly due to soil saturation
• A storm system that dumped inches of rain over several hours

If those conditions don’t apply, and your pump keeps running with no clear trigger, something may be off.

Common Reasons Your Sump Pump Keeps Running

There are several mechanical and environmental causes that can lead to a system that never seems to take a break. Let’s look at the most likely culprits.

Stuck Float Switch

The float switch signals your sump pump to turn on and off based on the amount of water in the pit. If it gets stuck in the “on” position due to debris, wear or misalignment, the pump won’t know when to stop.

Clogged Or Frozen Discharge Pipe

If the discharge pipe is blocked, water can’t leave the sump basin. Your pump will keep cycling in an attempt to remove water. However, if nothing is removed, the system will continue running.

Pump Too Small For the Job

If your pump isn’t sized correctly for the amount of water it needs to handle, it may run constantly and still struggle to keep up. This improper sizing can lead to system burnout and premature failure.

Incorrect Installation Or Poor Drainage

Improper grading, drainage issues around your home or even a poorly installed pump can cause water to flow continuously into the sump pit. This overflow can trigger nonstop activity. Our team can help you determine which sump pump type is best for your home, installing it according to industry-standard practices for best performance.

Why Sump Pump Runs Continuously Even Without Rain

If your system keeps running even when it’s not raining, that’s often a red flag. This issue could mean:

• A broken check valve is allowing water to backflow into the pit.
• A high water table in your area is causing persistent groundwater seepage.
• Plumbing leaks in the home are draining toward the sump pit.

It’s always a good idea to have a professional sump pump inspection if your system seems out of sync with the weather conditions.
