KNOW WHAT TO LOOK FOR the Best Battery Backup Sump Pump

Here are the important features and factors you need to look for when choosing for the best battery backup sump pump.

1. Type: Pedestal or Submersible

Choosing between the two types has its respective pros and cons. Pedestal sump pumps are more affordable compared to submersible types. They are also easier to maintain and repair.

In contrast, submersible types can be hidden and have a low noise level. Submersible sump pumps are also safer because children won’t be able to play with it. This is ideal when the basement is used as your main living area.

In terms of durability, a submersible sump pump can last around 5 to 15 years. Whereas, pedestal type lasts longer, approximately 25 to 30 years. Submersible types have shorter life span because of their nature of being always in contact with water. This speeds up the wearing of the parts of the pump.

2. Horsepower

Typically, sump pumps have horsepower ranging from 1/6 to ½ hp. The horsepower rating exhibits the pump's strength. Likewise, the higher the hp rating, the more expensive is the unit.

3. Gallons per Minute (GPM) or Gallons per Hour (GPH)

Next thing to consider, the capacity or rate of the sump pump. This feature entails the efficiency of the sump pump. The efficiency is reflected on the GPM or GPH rating and the respective vertical distance between the pump’s base up to the highest vertical point of discharge.

A pump may have a GPM rating of 2400GPM but that might be measured from a vertical height of 1 foot. If you plan to throw the water to a higher vertical distance, then the GPM rating will surely decrease.

4. Battery

A battery backup sump pumps are run by two kinds of batteries: AC/DC and DC battery. These kinds of sump pumps only run when the AC power is off or the main pump doesn't work.

Meanwhile, for units who runs on both AC and DC, it can run on AC power if electricity is present while not consuming the DC power. Once, AC is out power source switches on DC and runs again.

Other considerations, you can also categorize batteries as lead-acid batteries and maintenance-free batteries. Choosing which one will greatly depend on your preference and convenience.

5. Float Switch

Mostly, a backup battery sump pump is used to supplement the primary pump in case its capacity cannot hold the water level. Having a float switch is ideal to automatically activate your backup battery sump pump whenever the water level rises quickly.

6. Wifi and Smartphone Connectivity

The advent of new technology paved the way for smarter innovations with this device. A few modern units are already wifi capable and can connect with other gadgets and devices. Once, the backup battery sump pump is activated, it sends an email or SMS to the owner’s smartphone or device to alert them of the emergency.
