What Happens to Your Sump Pump During a Power Outage?

A sump pump is the first line of defense against indoor flooding and water damage, especially in areas prone to heavy rainfall or storms. These systems are designed to remove accumulated water in basements and crawlspaces by pumping it away from the foundation. However, mechanical systems can fail when needed the most, and a sump pump is no exception. This is where Rooter Man comes in as your trusted plumbing service provider. We believe that integrating a battery backup can ensure your unit functions as expected during outages, providing peace of mind throughout.

How a Sump Pump Works

As mentioned, sump pumps are designed to remove water in low areas like basements and crawlspaces. With this in mind, a professional sump pump installation is crucial in ensuring optimal and reliable function when you need it the most. A strategically placed unit automatically activates when water exceeds a certain level in the pit, pumping it away from the foundation and into a septic tank or sewer line.

Although most systems are powered by electricity, some models are powered by other energy sources, such as water pressure. The pump’s motor pushes water through interconnected pipes, keeping the basement dry and preventing water damage. If this process fails, early intervention by a plumbing repair service provider can help restore functionality.

Why Sump Pumps Need a Battery Backup?

While professional sump pump installation is crucial in preventing water damage, your system only remains useful if it continues to function when needed. This means a reliable and steady power supply even during storm-related outages. If you want to upgrade an existing system or install a new one, addressing power failures can give you peace of mind that your basement is flood-proof.

Traditional sump pumps cannot work effectively without power, hence the need to invest in an extra layer of security. By working with a licensed plumbing service provider, you can install the right backup battery to keep water at bay and protect low areas on the property from potential flooding.

Common Causes of Sump Pump Failures

Sump pumps often fail for several reasons, and familiarizing yourself with these causes can help you prepare for potential issues. Let’s explore some of the common causes of system failure to ensure you make informed decisions.

Power Outages

As stated, power loss is a significant cause of sump pump malfunction when you need it the most. Once the power goes out, electric-powered systems cannot pump out water in the basin or pit quickly, leading to potential flooding. Power outages are common during high winds, storms, or other weather-related events, making a battery backup system crucial.

Mechanical Failures

Some sump pump systems are mechanical devices, which means that they can wear out over time if left unattended. Whether it is clogged, corroded, or damaged parts, delaying professional plumbing repair services can cause a malfunction. Nothing is more frustrating than a sudden system failure, especially during heavy use.

Overwhelmed Pump

Another reason for sump pump failure is when too much water in the pit overwhelms the pump. This is a common occurrence during heavy rains or adverse weather conditions, as more water is entering the pit than the pump can remove. In such cases, installing a backup pump that can handle the increased water flow while utilizing the available power effectively can make a big difference.

Now that you know what happens to a sump pump during a power outage and viable solutions to ensure reliable performance, you can protect your home from flooding. Contact Rooter Man to book a consultation with our licensed plumbers and enjoy peace of mind during storms or emergencies.
