General Information about the Battery Backup Sump Pump

As you can notice, your sump is normally down below the floor level. It has the main sump pump at the bottom. You can have the battery backup sump pump sitting a little bit higher than the primary one. Moreover, you need to have the check valves and the connections.

In many cases, you can have the power come from the battery which is sitting in the protective case. On the other hand, they may frequently be in some types of case, so that you are protecting the battery as well as the floor.

In case there are any acids that come out of the battery, you can prevent a big accident from happening. Besides, the power is coming from the battery that is in the case. You only need to lift up the lid, and you can see the posts where the power comes from. This component helps to operate the backup sump pump.

The trickle charger has another cord that goes over and is plugged into the wall. Therefore, it is very important for us to verify the whole system is operating. You need to check the water level in the battery. Also, check the sump to make sure that the backup sump pump switch does turn the pump on.

Make sure that we are keeping the charge adequate. In some charges, there is a light readout that will indicate the level of charge. Thanks to this element, this will provide some backup protection for the home in case the primary sump pump fails or if the power goes out. This backup system will start operating and keep your basement dry.

What Should You Look For when Finding the Best Battery Backup Sump Pump?

Identify your demand

Before deciding to buy anything, you need to know your need first since it can help you make the right decision. Therefore, you should write down your purpose when purchasing the battery backup sump pump.

For instance, you want to protect the items in your basement, avoid the damage from flooding or sudden power cut. By asking yourself this question, you can know clearly what kind of product you should aim.

The types of battery for the backup sump pump

These days, there are mainly 2 types of batteries that you need to consider. I am talking about the AGM as well as the Deep Cycle Marine. You can relate the Deep Cycle Marine to the system of the older cars. Therefore, this kind of battery needs adding water for the best result.

On the other hand, the AGM does not need additional water thanks to the improvement in its technology. As a result, the AGM can last for about 5 to 7 years. Also, it tends to offer more run time than the Deep Cycle Marine.

The materials

When mentioning the materials of the battery backup sump pump, I highly recommend the cast iron. After using many models in a long time, I am sure that cast iron is more durable and rugged than the plastic components.

The capacity

After going through the materials, you need to look at the working capacity of the battery backup sump pump. This factor is essential since it will affect your whole system. In case you buy a backup sump pump that provides less capacity than the primary one, it will make a burden on you.

In this situation, the backup system cannot replace the primary pump when needed. As a consequence, make sure that you do not make this silly mistake since you have to buy another one for sure.
