Factors To Look For in a Battery Backup Sump Pump:

We can’t ignore that backup sump pumps are necessary to get rid of unwanted water. No matter what brand you choose, there are always some crucial factors you need to consider before making the final purchase; let’s make it easier for you to understand more thoroughly what to look for in a backup sump pump.

1. Size

The size of the backup sump pump matters a lot, depending on the sump. If the size of your sump is small, you would need to consider a small backup pump. Moreover, you are the one to be sure if you have enough space at home for its installation. Ideally, people prefer backup pumps with space efficiency.

2. Power

The product should have enough capacity to supply the required daily energy. However, this is always there in the product description part. The powerful backup pump saves both time and energy.

3. Quality

Quality, of course, is the most important factor one considers making a purchase, no matter what the product is. The same is the case with a backup pump. It would help if you saw whether the material is durable or not. Units made of cast irons are durable and come with complete longevity. However, some people also go for plastic units, but they are not as durable as cast iron. That is dependent upon your budget.

4. The safety features and installation

You need to consider the safety features before your final purchase. Safety matters most when you have children at home. A product with maximum protection is all you need.

5. The Installation

You don’t want a product with a tricky installation process. Avoid buying units that need extra tools for their installation. That is how you would save both time and money.

6. The battery charging capacity

The battery charging is another vital factor to be considered. You need to check the voltage of the charger that complements the pump. Some take more time to charge the batteries. You need to purchase a considerably large battery in critical cases, such as frequent power outages.

7. The Pump Capacity

Pumps exceeding 35 to 6o gallons per minute or, in other words, pumps that exceed about 36,000 gallons per hour is a pump with ideal pumping capacity. So, going for a perfect pump with an excellent capacity is always the rational choice.

One mostly ponders if a battery backup sump pump is worth it. If you frequently face flooding issues and power outages, i.e., once a year or more, the investment in a battery backup is worth it. That is how you would be able to provide enough safety to your house.

Another confusion may arise about how long sump pump backup batteries last. Well, it depends as some of them last up to 53 hours with a pumping rate of 2,300. On the contrary, in case of severe water issues, it may last only 12 hours as the pump functions every other minute. Lastly, if you have confused about if you can use a car battery for a backup sump pump, let me make it clear. A car battery would never last long.
