Battery Operated Sump Pumps

If your home frequently loses electricity during storms, consider having a battery operated sump pump installed in your basement. With a sump pump fitted with a battery backup system, even when the power fails, you don't need to worry about water damaging your home.

How Battery Operated Sump Pumps Work

Battery backup sump pumps work identically to regular sump pumps when your power is on and functioning. When water enters the sump pit, it trips a switch in the pump, which sends the water up and out of your home.

The difference is that a battery backup pump will function even when there is a loss of power. When the power is off, the pump automatically switches to its backup system, so there is no lag in water removal. So a large storm that takes down power lines and leaves you without power will have no effect on whether or not your pump continues to function.

When You Need a Battery Backup Pump

Not everyone would truly benefit from having a battery backup system, which can cost significantly more than a standard sump pump. Consider getting a battery system if you fall into one of these categories.

Frequent Pump Use

If your home or yard is below the water table and your pump works nearly every time there is a storm, it's a good idea to have battery backup. Even if you only lose power infrequently, the fact that you rely heavily on a pump makes a backup system worthwhile.

Frequent Power Outages

If you live in a rural area, a heavily wooded area or an area that is prone to frequent power outages, a backup battery sump pump can be beneficial, even if you only need the pump once in a while. Because power outages are more likely to happen during storms or heavy rainfall, a battery backup system can give you peace of mind.

Types of Battery Backup Sump Pumps

Just like regular sump pumps, battery pumps come in a wide range of choices, from high capacity to those that will also pump out sewage in case of a septic failure. Be sure to measure the size of your sump pit and take into consideration how often the pump will be used, both with electricity and without before you buy.

Large Capacity Models

If your home is prone to flooding, you have a large sump pit or your basement is significantly below the water table, a large capacity model may be the right one for you. Models include:

Auxiliary Models

If you only need a sump pump to function once in a while, an auxiliary model can be the answer. These battery operated pumps are mounted next to the sump, rather than in it. This prevents clogs that could stop it from working when and if it is needed. Models include:

Extra Long Battery Use

If you live in an area that loses power for extended amounts of time, you may need a system that either has extended battery life, or the option to switch out batteries. This can help ensure your home stays dry no matter how long the power is out. Models include:

Avoid Storm Flooding

A sump pump with a battery backup can mean the difference between getting through a storm with your home intact, and emerging with flood or water damage. Consider replacing your standard sump pump with a battery backup model during your next renovation to help ensure its long life.
