Unusual Sump Pump Issues You Need To Know About

A home's basement is an essential part of the house for many families. It is a great space for extra storage, laundry, or even a cozy living area. However, having a damp and flooded basement can be a homeowner's nightmare.



Fortunately, sump pumps can help keep basements dry by collecting groundwater and pumping it outside the house. Although sump pumps are relatively simple devices, they can still experience issues that can cause flooding. This blog post will discuss unusual sump pump issues that you need to know about.

Malfunctioning Float Switches

The float switch, a crucial component of a sump pump, plays a pivotal role in its operation. This device functions by precisely rising and falling in response to changes in the water level, effectively triggering the pump to either turn on or off.

However, when the float switch malfunctions, it can lead to undesirable outcomes. For instance, if the switch fails to activate, the pump will remain dormant, potentially causing water damage.

On the other hand, a malfunctioning float switch may cause the pump to turn on and off erratically, leading to unnecessary wear and tear. Such malfunctions can arise from various factors, including debris buildup within the switch mechanism or underlying wiring problems. Therefore, ensuring the proper functioning of the float switch is essential for the optimal performance and reliability of the sump pump.

Blocked Discharge Pipe

When installing a sump pump, one critical component is the discharge pipe. A blocked pipe will cause the water to back up and overflow the basin, resulting in flooding. The debris that gets trapped along the way can cause blockages, but they can also be a result of soil erosion, frost heave, or damaged pipes. Regular cleaning of the discharge pipe and the installation of a check valve to prevent backflow can help resolve this issue.

Frozen Discharge Lines

In colder climates, sump pump discharge lines can freeze due to low temperatures. This occurs when the water inside the line cools and forms ice, blocking the flow and preventing the pump from effectively removing water from the basement. As a result, there is an increased risk of flooding and water damage. To prevent this issue, homeowners can take proactive measures such as burying the discharge line deeper to ensure it is below the frost line or insulating the line with materials that provide additional protection against freezing temperatures. These preventive steps help to maintain the functionality of the sump pump and minimize the potential for basement flooding during cold weather conditions.

Irregular Cycling

A sump pump that switches on and off irregularly can be a sign of several issues. For example, the pump may be too small, the float might be defective, or the check valve may not be working adequately. Any of these issues can cause the pump to overwork and eventually break down. If you notice your sump pump is cycling irregularly or constantly running, it's best to have it professionally inspected to prevent long-term damage.

Switch Failure

Sump pumps are equipped with different types of switches, such as float switches, electronic sensors, or pressure switches, that trigger the pump to turn on when the water reaches a specific level inside the basin. A fault in the switch can cause the pump to malfunction, leading to flooding in the basement. Regular monitoring and inspection of the switch are necessary. If you suspect a malfunction, seek professional help promptly.

Power Failure

Power outages can happen anytime, and they tend to coincide with severe weather conditions. In such events, your sump pump will not be able to function until the power is restored. The solution is to install a backup battery pump system or generator that immediately restores the power supply and allows the pump to continue operating. Consider obtaining an alternative source of power to maintain your sump pump's functionality, even in the event of a power failure.

Banging Noises

While it's normal for sump pumps to produce some level of noise during operation, a persistent banging noise is not typical and should be addressed immediately. This sound could indicate several problems. One common cause is the water hammer effect, which occurs when the water flow is suddenly shut off. This creates a pressure surge or wave, often a result of a faulty check valve.

A loose impeller, the component that pushes the water out of the pump, can also cause banging noises. It's best to seek professional help if you encounter this issue. Ignoring it could lead to severe damage to the sump pump and even flooding in your basement. Regular maintenance and inspections can help prevent such problems and ensure the longevity of your sump pump.
