What is a Battery Backup Sump Pump?

First of all, let us fill you in about what regular sump pumps are. They are one of the water extraction tools that are installed under the basement or on the top floor. These usually consist of a motor, an intake pipe, and a dispensing tube.

They are typically activated using a floating switch, which sends the signal to the engine when the water level is above the basement ground level.

And the motor gets activated, it will suck all of the water from the ground through the intake line and disperse it to the exhaust pipe. Also, the battery backup version has an additional cell, which will enable the tool to do all of that work even when there is a power outage.

How to Find the Right Battery Backup Sump Pump?

Going through the reviews will not be enough if you really want to get one of the well-performing ones. For that, you would have to keep some factors in mind alongside the reviews. The points that we are talking about are as follows:

Motors

First and foremost, you need to consider the motors that the unit is going to come with. For most of the cases, they are going to be well capable, but there are many that are not really that powerful.

And in the case of power, what you need to factor in is the amps. The higher the amps, the more powerful the motors are going to be.

Alongside the power, you should also consider whether the motors are efficient or not. As these are going to utilize battery power, you would be able to get longer runtime with efficient motors. For that reason, we would recommend you shoot for the ones with a higher level of efficiency.

Compatibility

Most of the kits are going to be a standalone battery type. For those kits, you will have to install the battery to your existing sump pump. And you will need to consider whether the current unit that you have is compatible with the cell or not.

If you happen to get something that is incompatible, you would have a useless battery lying in the basement, which would not be that much of a cost-efficient decision.

Controller Unit

The controller board is what is going to allow you to monitor the overall state of the battery and the motor. You would be able to see whether the cell is charged enough or not and whether the other components are working adequately. Without a proper controller board, you would not be able to do all of that.

Other than that, many will incorporate a Wi-Fi modem. With those, you would be able to monitor the device wirelessly and from a farther distance. You would not have to get to your basement just to check whether the unit is operating optimally or not.

However, you need to make sure that the app is refined, or else you are going to have trouble monitoring the machine.

Alongside that, ensure that the Wi-Fi signal can be accessed from a far distance. If the Wi-Fi chip is not that strong enough, you would have to get closer to the basement just to connect with the device.

Charging Mechanism

Most of the units are going to utilize AGM cells. And if they are not charged properly, the battery would degrade relatively quickly.

When that does occur, you would have to replace the cells, which means spending extra money. For that reason, you need to ensure that the unit can charge the cells adequately and does not overcharge the cells.

Capacity

Another thing that you need to consider is the capacity of the batteries. The higher the capacity, the longer the runtime is going to be.

And considering that there are possibilities that the power outage can last for more than one or two days, you would want to get something that has a higher capacity. With those, the device would be able to run for multiple days without any issues.

GPH Rating

The GPH rating is going to rely on the power of the cell and the power of the motor as well. If you happen to get something that has a powerful motor, but the battery cannot offer the power to the motor, the GPH rating would be pretty low.

Considering that, if you want to move all of the accumulated water in a short amount of time, you would have to factor in the power of both the components. The power of the battery is generally stated as Ah. And the higher that number is, the more powerful the cell is going to be.


Benefits of Having This Item

The battery backup version of the unit offers the same benefits as the regular versions but adds a few cherries on the top. That being said, the advantages that you are going to enjoy after getting this item are as follows:

Prevents Flooding

As we have mentioned above, the basement floors are prone to water accumulation. And with one of these installed on that floor, you would be able to prevent that from happening. Alongside that, you will also avoid the water damages that might occur when that flooding happens.

Protects the Electrical Lines

For most of the housings, the electrical lines are going to be on the basement floor. And electrical lines and water does not go that well. So, you can prevent electrical accidents from occurring during flooding and heavy rain seasons by getting one of these.

Reduces the Chances of Mold and Mildew Growth

Water accumulation can promote mildew and mold growth. And molds and mildews in the basement means your upper floors are not going to be that much hygienic. Well, you can prevent that from happening by installing these.

Stay Worry-free During Power Outages

As these are battery-powered, you would not have to worry about them when a power outage does occur. That means these will operate adequately even when the power lines are cut due to extreme flooding and heavy rains.

Cleaning and Maintenance of Battery Backup Sump Pumps

It goes without saying that if you want to get the most out of something, you would have to take proper care of it and maintain it properly. And the same thing goes for these as well. That being said, the steps that you would have to follow for maintenance and to clean these are:

  • First, you need to take off the opening screen of the inlet. After opening the inlet screen, you would have to disassemble the parts accordingly. Ensure that you use proper tools for this, or else there would be a chance of you damaging the mounts and the screws.
  • Now that you have taken off the inlet screen and disassembled the parts, you would have to check whether the line is clogged or not. If you notice any growth of molds and mildews, you would have to clean it. Use hot water and a cleaning solution for that.
  • After ensuring that the pipes are clean, you need to make sure that the power cord is in good shape. Check whether there is any wear or tear on the cable or not. If you notice any, we would recommend replacing it or taping the wear with PVC tape.
  • Then, you have to check whether the motor is performing adequately or not. Once everything is checked, you should assemble the parts and screw the fasteners in.

Installation of Battery Backup Sump Pumps

The installation procedure is crucial if you want your pumps to perform adequately. Without installing these properly, you would not be able to get a good performance out of it. And the installation procedure of these are as stated;

  1. 1
    First of all, you need to check whether the machine is assembled or not. If you happen to get a unit that does not come pre-assembled, you need to assemble the parts first. Most of the manufacturers will include a guideline, which would make the assembly process easy.
  2. 2
    After assembling it, you need to install the mounting hardware. Most of the packages should come with the required hardware. However, if you got something that does not come with them, you need to purchase them separately.
  3. 3
    Now that you have installed the mounting hardware, you would have to install the pump first. Screw it in the mounting hardware that you have installed. And then you need to connect the battery.
    On that note, some of the units might not include cells. For those, you would have to purchase a compatible cell first.
  4. 4
    After getting all of the things installed, you should connect an outlet pipe and place it outside your home. Once all of that is done, connect the power cord, and the device should start working.
