Frequently Asked Questions (FAQ)
Who makes the best battery backup sump pump?
There are dozens if not hundreds of battery backup sump pumps from which to choose. Some are a one-time purchase while others last a lifetime. Which is the best to choose?
The most important factor is the pump itself. If you have a single-pump system, then the same backup unit could work just fine. If you have a dual-pump system, then make sure it supports both pumps.
Next, we suggest you look at the battery source. Most of these backup pumps are self-powered, but the self-powering options are generally a little more expensive. Instead, look for a model that uses standard AA or AAA batteries. They are cheaper, easier to find, and are faster to change out if your pump needs a quick recharge.
How long will Sump Pump Battery Backup Last?
Sump pumps are an essential piece of hardware in homes vulnerable to flooding and large amounts of rain during heavy storms. As you probably already know, the sump pump is a mechanical device that pushes water out of your basement and back into natural drainage.
Using a sump pump is much more effective than traditional drainage methods because it eliminates the need for gravity to push water away from your foundation. Sump pumps become even more helpful in homes that have basements that slope towards the outside. In these homes, water will begin to pool or run back towards the foundation unless something is done to keep it outside.
In the US, over 10,000 homes experience basement flooding annually. These numbers are staggering enough, but when you consider the immense damage losses, they are downright frightening.
Is a battery backup sump pump worth it?
Having a battery backup for your sump pump can be critical in protecting you home in the event of a prolonged power outage. When the power goes out, your primary pump will turn off and your battery backup will immediately kick on to protect your basement.
As long as the power outage doesn't last too long, the battery backup will keep your basement dry. However, if the power outage lasts longer than your battery is designed to handle, then you might find yourself in a bit of a predicament.
The first thing you should do is contact the makers of the battery backup and find out how long their batteries should ideally run continuously. If your brand is in line with that, then consider buying a new battery for the backup. However, if your brand is not ideal, then your battery might be aging. If this is the case, then you may want to have a professional company come and test your back-up pump and battery.
How often replace backup sump pump battery?
How often you need to replace the battery in your backup sump pump depends entirely on how often you use it. Having your battery tested and looked at by a professional in every 6 months is important to prevent any issues.
During the full test, professional will check the full battery and/or battery backup system to make sure there are no cracks, upgrade the backup pump and finally check the battery for charge. However, before that, the frequency of battery replacement depends on the use.
If you have to replace sump pump battery frequently, make sure you turn on the pump for several minutes every week and test it. Sometimes, the frequency of use makes the entire system becomes weak and you need to buy new battery.
It is always wise to buy a backup pump if you have a sump pump. It can give you peace of mind when a storm is brewing. You can use this buying guide to figure out which backup sump pump is best for your home use, be it a constant stream in heavy rains or the pump going off and on due to a heavy storm.
