How to choose the best battery backup sump pump

1. Consider the status of the battery

The first thing to consider when selecting a best sump pump battery backup. After all, these are battery-operated sump pumps. Therefore, you will need to get a reliable unit, and this should be in terms of the included battery.

Therefore, consider features such as,

• Power source

Battery backup sump pumps derive their power from two sources, where you can locate an AC/DC power source or a DC power source.

An AC/DC-powered sump pump derives its power from an AC or DC power source. Such pumps can operate from an AC power outlet when the power is on, leaving them to conserve the battery.

Once the power goes out, the pumps switch to the DC power source, as such, making them the best options when you want to ensure reliable performance.

On the other hand, DC-powered backup sump pumps derive their power from a battery, which means that such pumps are more likely to run on a low battery. Therefore, unless you will not forget to recharge your battery, you can rely on DC-powered backup sump pumps.

• Type of battery

There are different types of batteries used in a backup sump pump. For instance, you will come across the pump cycle batteries and the lead-acid batteries. Also referred to as maintenance-free batteries, the deep cycle batteries do not require any maintenance due to the fully-sealed design. As a result, you can set the batteries and forget about their existence.

On the other hand, well acid batteries, otherwise referred to as lead-acid batteries, require some maintenance since you will be required to add distilled water occasionally. Therefore, decide whether to opt for the deep cycle batteries or the lead-acid batteries.

  1. Flow Rate

A good backup sump pump system should stand up for the challenge that it is likely to face. For instance, if you will be dealing with a big area, you will need to get a pump designed to draw a lot of water at a time to protect the area from flooding.

On the other hand, if you will be dealing with a small area, a pump with an average flow rate will draw the water without resulting in floods. Therefore, ensure that the backup sump pump’s flow rate is consistent with the size of the area you will be dealing with.

  1. Float switch

If you want to acquire a reliable backup sump pump, you will need to get a pump that features a float switch. For those wondering what a float switch is, this is a kind of a level sensor that detects the level of the water. Once it detects too much water, it triggers the pump enabling it to draw the water out, which means less work.

Tips for a battery backup sump pump maintenance

1. Inspect the power cords– If you want to ensure that your backup sump pump runs effectively, you will need to inspect the power cords. In this case, ensure that the power cords aren’t tangled to prevent accidents. Also, inspect to ensure that they are not in a position where they are likely to get tangled with the float.

2. Clean the pit– You will need to ensure that the pit is clean at all times. The reason behind this is that you do not want the dirt in the pit to clog the impeller or discharge tube. So, be on the lookout to ensure that the pi is clean at all times.

3. Inspect the drain line– Besides the power cords, you will need to look at the drain line to ensure that it is not damaged or destroyed. Also, ensure that the drain line is free of damage so that you can keep the pump functioning effectively in all instances.

4. Ensure proper positioning of the float– The float should be positioned in such a way that it can move freely without being obstructed by other objects. So, ensure that it can move up and down freely to ensure that the sump pump is working effectively.

Final verdict

You do not want to be a homeowner who discovers that the primary sump pump has a problem only after a flooded basement. The reason I urge you to purchase the reviewed products.

The best sump pump with battery backup system, you can be sure to maintain a dry basement even after a power outage or a fail of the primary pump since the unit is designed to start up automatically after detecting a problem in the primary sump pump.
