What to Look for While Buying the Best Battery Backup for Existing Sump Pump

Here are some things that you must consider while buying the best battery backup for an existing sump pump;

Material Construction

The first thing you should consider while buying the best battery backup for your sump pump is its construction as it is the determinant of the life of this system. For this purpose, I would recommend you go for thermoplastic construction as it is waterproof and resistant to corrosion. If you are restrained by budget, you can go for stainless steel, however, make sure it is water-resistant to make sure it prevents moisture from getting into the element.

Flow Rate

It is equally important to consider the flow rate or capacity of your battery backup as it primarily determines the time and efficiency of your pump. In simple words, it is measured in GPH or gallons per hour and is the value with which your water is removed from the pump while your battery is fully charged. For this purpose, the first thing you should look into is your individual requirements.

Most commonly, you can remove average water between 1800 and 2400 GPH, be it a primary pump or a backup system. This range comes with an average length of 10 ft lift that makes it easy to remove water from below the basement to ground level. If you are only looking for something for emergency situations, it is ideal that you at least have something above 1800 GPH to ensure consistent power and flow rate.

Battery and Runtime

Another thing that can make a huge influence on the performance of your battery backup is the battery life. For this purpose, it is important to consider that a quality backup system would have a 12V acid-free battery as it provides you with a power range between 40 and 100 amp-hours. It is equally significant to note that the life of the battery depends on how much water is entering the pump.

In simple words, the rule of thumb says the more the power, the better the flow rate and longer the time run your backup system has. Also, if you are restrained by budget, I would recommend you at least go for 40 amp hours as it can make the process fast and can save you from the struggle during emergencies. All in all, it must be compatible with your needs. Also, check out the best generators for sump pumps if you want longer runtime.

Installation and Convenience

Last but not least, while buying a battery backup, it is ideal that you make sure it is easy to install. For this purpose, I would suggest you go for something that demands basic plumbing techniques. However, if you have no previous experience, it is ideal that you go for professional help for installation. Also, it becomes extremely important when you have a combination system as it can directly impact the drain pipes and already existing pumps.

In the end, I hope you soon will find the best battery backup for your existing sump pump, with the help of these instructions, as per your liking.

FAQs regarding Sump Pump Battery Backup System

Can you add battery backup to an existing sump pump?

Yes, the new battery backup pumps are installed in the same sump basin where it was originally placed. Likewise, when the power goes out, these pumps and basins are used to pump out the water. Hence, if you are looking for an upgrade for your existing sump pump, you can always go for options like Basement Watchdog and PumpSpy PS2000 for their enhanced flow rate and consistent power supply.

How long does the battery backup last for the sump pump?

Well, it primarily depends on the battery originally used for the sump pump. Most commonly, you can find 12V batteries for these pumps that are designed to last you for 90 hours or even longer. However, it is equally important to consider your individual requirements as the life of your battery depends on how much water is entering the pump.

Do I need a plumber to install a battery backup?

It primarily depends on the design of your battery backup. On average, you most probably would need a plumber service as it demands connecting new pipes and preventing moisture from getting in. Hence, it becomes ideal that you check for some professionals that help you in checking the valves and making sure that all pipes are watertight.
