Why Invest in a Good Battery Backup Sump Pump?
A quality battery backup sump pump system is not inexpensive. It’s possible that you’ll never even need it. Here are some reasons to think about shelling out the cash:
Protect Your Home Investment
Your home is entirely shielded from intrusive water by your primary sump pump. But electricity from the grid is necessary. Storms are a frequent occasion when the grid’s power can be disrupted. It’s possible that the storm that cut the power also dumped a lot of rain. Rain that might end up in your crawl space or basement.
In addition to being capable of handling this challenge, a good battery backup sump pump will also keep you informed of any system issues while you’re waiting for the storm.
Unusual Rain Event Protection
Nature occasionally bestows upon us an unexpected gift. Having an emergency sump pump set up and ready to go could mean the difference between having a dry basement and one that is flooded should a rain event occur that is significant enough to overwhelm your main sump pump.
Peace of Mind
For peace of mind, any backup system is preferable to none at all. However, their capacity to communicate with their owner is frequently cited as the main distinction between different battery backup sump pumps.
Sending out alerts for things like low battery issues, high water warnings, and alarms that have been activated is important for maintaining confidence in your backup system. The more information the system can clearly convey to you, the better.
What Are the Advantages of Owning a Battery Backup Sump Pump?
The main benefit of owning a battery backup sump pump is peace of mind. Flooding may occur after an electrical outage if there is no backup pump to remove the water that collects in the sump pump basin.
- For peace of mind in the event of a power outage, consider installing a battery backup pump, a primary pump, and/or a float switch.
- Your smartphone can receive notifications from a connected backup sump pump informing you of the pump’s status.
- A primary pump and a backup pump are both included in a combination battery backup unit to simplify installation.
How to Determine Which Battery Backup Sump Pump is Best for You?
You won’t need to use your backup pump very often, hopefully. But when you do, it’s nice to know that the person you picked is capable. You should take into account the following elements to choose the best battery backup sump pump for your needs.
Price
There are typically two types of battery backup sump pumps. Metal-bodied pumps are both slightly more expensive and significantly more durable than thermoplastic-bodied pumps. The cost of a backup system primarily depends on the features that it has in addition to those two factors.
The price of an emergency sump pump system is increased by optional extras like home system connectivity, alarm systems, complex charging systems, battery compatibility, and all-around user-friendliness.
Examine the choices by weighing your desired level of convenience against a comfortable price point.
Capacity
Your home, its requirements, and your level of comfort are all particular. Homes located in areas that are particularly wet or where the water table is high will require very different sump pump capacities than homes that are surrounded by a desert.
For several days following a period of heavy rain, older homes may experience water seeping through the basement walls. It’s possible that newer homes were built to quickly flush out as much water as possible.
In the event of a protracted power outage, your backup sump pump may not be required to have as much water pumping capacity as your main sump pump, but it should be able to move enough water to keep things moist.
Battery Type
Deep-cycle batteries, which are typically sold separately, are required for use with battery backup sump pumps. They come in various shapes and sizes. Although the majority of emergency sump pumps can operate under emergency conditions with any 12-volt battery, some are more effective than others. The recommended deep-cycle lead-acid battery has a rating of at least 75 amp-hours. Batteries with a rating of 120 amp-hours are available for the greatest protection.
Keep in mind that maintenance-free batteries still require periodic inspections to make sure they are functioning properly and aren’t damaged in any way.
FAQ About Battery Backup Sump Pump
How Much Does a Battery Backup Sump Pump Cost?
A battery backup sump pump system costs an average of $900 to install professionally. The price of the primary sump pump is not included. The situation of the home and the features you want have a significant impact on the cost of installing a backup system.
What is the Lifespan of a Battery Backup Sump Pump?
Infrequent use, which is frequently the case, can extend the lifespan of a backup sump pump by several years. If the primary pump needs to be replaced, some homeowners also replace the backup pump. However, the battery only has a typical expected life of about four years.
How Long Does a Battery Run a Backup Sump Pump?
A backup sump pump can be operated continuously for about six hours on a new or well-maintained deep-cycle battery with a 75 amp-hour rating. That equates to about two days of sporadic real-world use. For every 10 amp-hours of higher or lower battery rating, add or subtract roughly one hour of continuous runtime. Older batteries and batteries that have not been properly maintained will perform less well.
Are Battery Backup Sump Pumps Worth It?
There is little doubt that having a backup for that pump is worthwhile if valuables are kept in a location that could flood if it didn’t have a sump pump. Some homes may not require a backup emergency pump because of solid walls, efficient floor drains, or large empty spaces. If the primary pump fails in those situations, a disaster may not be imminent.
An insurance policy provided by a battery backup sump pump is worth the price for the majority of homeowners who reside in areas where a sump pump is required because it lowers the possibility of avoidable water damage to the house and its contents.
Conclusion on Best Battery Backup Sump Pump
