Factors to Consider When Choosing the Best Battery Backup Sump Pump

1. Flow Rate

Always keep in mind that the backup pump is not designed to take the place of the primary model. Therefore, having a model with the same flow rate as the primary model can be the best idea, just in case your primary pump fails.

When thinking of the flow rate, consider the amount of lift needed in your setup too. Because these pumps are drafted to draw water out of the basement, so you will possibly have to be moving it vertically by some few feet. These matters too when choosing the battery backup sump pump.

In some cases, the flow rate is usually the number of gallons moved at zero feet. The further vertical lift needed, the lower the number of gallons will get. You need a backup pump that can do at least 600 gallons per hour to make sure that it will always keep your basement dry. Luckily, most of the backup sump pump surpasses that therefore you should be fine.

2. Technology

When choosing the best battery backup sump pump consider the technology that comes with it. Choose one with an alarm so that you can stay aware of any issue with the pump. In case you end up buying a backup sump pump without an alarm, don’t worry because you can install a new one in the future.

Choose a backup sump pump that is compatible with a vertical float switch. The best electronic switches are the one with an internal sensor and detect water. When the water levels drop that pulls down the lever, which turns off the pump. Besides, when the water levels rise in the sump pit, the alarm will sound off.

Consider the piggyback prong too; if there are one or two cords in the back of the backup sump pump, you can assess them yourself. Examine them for piggyback compatibility. A tether float switch will initiate the pump when the float rises.

The piggyback prong is an incredible addition, for it controls the submersible pumps that do not have an automatic feature to control themselves. It is perfect for a pump with a failed switch. This low-cost alternative is better than having to replace the whole pump.

3. Material Used

Consider the material housing the battery. The best battery backup sump pump has thick thermoplastic. Also when choosing, you need to be aware of the material, whether it is waterproof or not. In case it isn’t, then it is your responsibility to place the battery above the pump.  The material should repel water so that the pump can still function when the basement flood.

Another thing concerning the material is whether it is rust-resistant. Cast iron and steel need to have coverings to shield them from rusting, but that can wear off over a period. Plastic housings are considered the best because they cannot corrode even though they are more prone to damage.

4. AC and DC power

We prefer backup pumps that can use the battery as well as runoff AC power. The reason for this is that you can lower the inclusive wear and tear on the battery since the pump will function when power is accessible.

The other advantage is that when the power resume, the system automatically recharges the battery. In case you had a pump that was relying on battery only, then you would have to recall doing this yourself. In some situations, if you did not even know that the pump is active, then you might not have the knowledge that the battery is drained, which could place you in a bad situation next time.

The best battery backup sump pump should have both AC and DC power inlet so that they can still function in case of a power outage.

A flooding basement is expensive, frustrating and the last thing any homeowner wishes to come home to, however, without the information of battery backup for the sump pumping system responsible for eliminating water, in cases such as power outage, the unwanted occurrence will continue taking place. We did look at the best battery backup sump pump in the market and factors to consider when choosing them.
