Sump Pump Running Nonstop? Here’s the Alarming Truth

A sump pump is an essential tool for homeowners in areas prone to flooding. It helps keep basements and crawl spaces dry by pumping out excess water. However, when a sump pump runs excessively, it can be a cause for concern. In this blog post, we will delve into the various reasons why a sump pump might be running so frequently and explore potential solutions.

Clogged Discharge Line

One of the most common reasons for a sump pump running excessively is a clogged discharge line. Debris, such as leaves, dirt, or even small animals, can accumulate over time and obstruct the flow of water. This blockage prevents the pump from effectively draining water away from the basement or crawl space. Inspect the discharge line regularly and clear any obstructions to ensure proper water flow.

Faulty Check Valve

A check valve is a device installed in the discharge line that prevents water from flowing back into the sump basin. If the check valve fails or becomes damaged, water can flow back into the basin, causing the pump to run unnecessarily. Replace a faulty check valve to ensure proper water flow and prevent the pump from running excessively.

Oversized Sump Pump

An oversized sump pump can also contribute to excessive running. A pump that is too large for the size of the sump basin will cycle on and off frequently, even when there is minimal water accumulation. This can lead to premature wear and tear on the pump. Consider replacing an oversized sump pump with a smaller, more appropriately sized model.

High Water Table

In areas with a high water table, groundwater can seep into the sump basin and trigger the pump to run frequently. This is especially common during heavy rainfall or snowmelt. Installing a sump pump with a higher pumping capacity or a backup sump pump can help mitigate this issue.

Leaky Basement or Crawl Space

A leaky basement or crawl space can allow water to seep into the sump basin, causing the pump to run excessively. Inspect your basement or crawl space for cracks, holes, or other openings that may be allowing water to enter. Seal any leaks to prevent water from accumulating in the sump basin and triggering the pump.

Improper Sump Basin Depth

The depth of the sump basin can also affect the frequency with which the sump pump runs. A shallow sump basin will fill up more quickly, causing the pump to cycle on and off more often. Ensure that the sump basin is deep enough to accommodate the expected water accumulation and prevent the pump from running unnecessarily.

Float Switch Malfunction

A float switch is a device that detects the water level in the sump basin and triggers the pump to turn on when the water reaches a certain level. If the float switch malfunctions or becomes stuck, the pump may run excessively or not turn on when needed. Inspect the float switch regularly and replace it if it is faulty.

The Bottom Line: Uninterrupted Basement Protection

By understanding the various reasons why a sump pump might be running so much, homeowners can take proactive steps to address the issue and ensure uninterrupted basement or crawl space protection. Regular maintenance, addressing underlying problems, and installing an appropriately sized sump pump can help minimize excessive pump operation and safeguard your property from water damage.

Questions We Hear a Lot

Q: Why does my sump pump run for a few seconds and then stop?
A: This is likely due to a faulty float switch or a shallow sump basin. Inspect the float switch and ensure it is operating correctly. If the sump basin is too shallow, consider replacing it with a deeper one.

Q: How often should I inspect my sump pump?
A: It is recommended to inspect your sump pump every few months, especially before and after heavy rainfall or snowmelt.

Q: Can I install a sump pump myself?
A: While it is possible to install a sump pump yourself, it is recommended to hire a licensed plumber if you are not comfortable with electrical work or plumbing.
