Can You Add Battery Backups To An Existing Sump Pump?

Almost every single sump pump can have a battery backup added to it, even if it wasn’t designed with one already included.

In fact, many homeowners are choosing to add battery backups to their sump pump because of the benefits they offer:

Protection Against Power Outages

Power outageshappen more frequently than youthink,disrupting yoursump pumps operation. If your power goesout,then your battery backup will kick in and keep it running until you can get the power going again. This means there are no gaps in protection for your home.

Protection Against Tripped Circuit

Your circuit trips as a precaution againstunexpected surges. This helps to protect your home fromelectrical fires and prevent damage to your appliances.It can take you a while to notice it's happened, but your sump pump won't have access to any power at that time. A battery backup will provide protection to cover these periods until you can reset the breaker and get power flowing again.

Protection Against Sump Pump Failure

If your sump pump becomes clogged or starts tofail,then the power can cut out. A battery backup will give an alternative power source to get it running again so it can keep removing water from your home.

Extra Protection During Extreme Weather

Unfortunately, power outages can often happen during periods of extremeweather,and this is where you need your sump pump the most. A battery backup will keep your pump runningduring these extreme conditions and keep floodwater out of your home.

4 Factors To Consider When Installing A Battery Backup

There are many different battery backups to choose from, and it can be challenging to know where to start.These are the key factors to consider which may help you narrow down the choices:

1. Alarm System

Part of the reason battery backup systems are so important is because you don't always notice that the sump pump has stopped working. Backups with built-in alarm systems will notify you when they kick in. This will let you know something iswrongand you need to take action, so it's definitely a feature to look out for.

2. Pump Capacity

Your pump capacity is the amount of water it can pump from your home in a given period. This is generally measured in gallons per minute orgallons per hourand gives you an idea of how much they can handle. If your battery backup kicks in, then it needs tobe able to provide the same amount of power so that the pump can keep working at the same pace. Look for a pump that offers the same gallons per hourso it will run properly.

3. Self-Test Feature

Your sump pump needs to run pretty frequently to keep it in working order. Some battery backups come with an automatictest feature which means they'll periodically switch on to test themselves. This activates your sump pump and keeps it running as it should, so it's a useful feature for a backup to have.

4. Battery Capacity

You should consider how often your sump pump runs and how much power you might need. The battery capacity is how long it will be able to run, and you need to pick a battery with enough capacity, or your pump will cut out before you can get the primary power source back on.

Battery Type

There are a few different types of batterybackups,but you should always opt for amarine battery(sometimes called a deep-cyclelead-acid battery). The output from this type of backup is measured in amps per hour and will give you a clear rating of how long it will run.
