What Size Backup Sump Pump Do I Need

What’s the Best Type of Backup Sump Pump Battery?

An average-sized home in an area with a normal water table will benefit from an annual irrigation system with a 1/3 horsepower sump pump that should suffice. Generally, 1/3 HP pumps can handle vertical lifts between 7 to 10 of water from the sump pit as long as the pipe run is between 3 and 25 long.

Is A Battery Backup Sump Pump Worth It

Whether or not a battery backup sump pump is worth it, and whether or not you should get a battery backup, depends on your situation and preferences. There is not a one-size-fits-all that will work for everyone, and there isnt a guarantee that a product that works great for someone else will work for you. The same goes for battery backups for sump pumps.

In general, emergency battery backups are worth it for people in rural areas or that live on the city outskirts. In fact, they are pretty much mandatory for people located in areas prone to natural disasters where power cuts often happen.

To determine whether you need a battery backup, try imagining this situation: A heavy rain happens, causing power outtakes. Is this something that is likely to happen in your area? If your answer is affirmative, then you certainly need a battery backup.

Sump Pump Battery Boxes And Chargers

Sump Pump battery chargers operate as both chargers and maintainers, keeping the battery fully charged and in optimal condition over a long period of time.

If the sump pump doesn’t have a reliable battery charger/maintainer, consider buying a dedicated one and connecting it to the battery.

Note: battery-powered sump pumps and similar emergency equipment MUST work reliably in the case of emergencies – if they don’t operate reliably, what’s the point of having them? Thus, any work on the sump pumps and their electric and electronic systems should be done by certified personnel or at least by someone who actually knows what to do. Seriously!

The preferred battery types of sump pump batteries are dual-purpose or deep-cycle AGM SLA batteries or Gel-CellSLA batteries.

Note: Car batteries are designed as starting/cranking batteries, being able to provide short bursts of power for shorter periods of time and thus are not the best choice for, what is easily possible, deep cycle applications. However, if your sump pump battery is dead for who knows what reason, hook your charged car battery and let it work – one deep discharge cycle will not harm starting battery, but the cycle use may shorten its operating life significantly.

Thus, when choosing a sump pump battery, go for a reliable deep cycle AGM battery from a reputable brand.

Most sump pump battery boxes accept Group or BCI Group .

Their sizes are:

– Group 27 batteries : 12.0625 x 6.8125 x 8.875 inches, 30.6 x 17.3 x 22.5 cm,

If youre reading this article, you likely understand why sump pumps are essential and might even have one in your basement already. However, its crucial to realize that sump pumps, on their own, have several limitations.

Here are 4 quick reasons why a sump pump with a battery backup makes for a much better investment for your home:

  • Power-independent: The first and most apparent difference with a battery backup sump pump is that its battery operated, making it power-independent. Suppose a heavy storm is simultaneously causing a power disruption and basement flooding. In that case, the battery-powered sump pump can still operate to keep your basement dry.
  • Additional protection: Battery backup sump pumps are often used alongside a primary pump plugged into the wall socket. Even with a stable power supply, these pumps could potentially fail. If that happens, the battery-powered sump pump can act as a backup, continuing to remove water from your basement.
  • Connectivity for monitoring: These days, sump pumps with backup batteries have plenty of high-tech features, such as modern connectivity. Unlike older pumps that you might still rely on, newer ones allow for remote monitoring and diagnostics. So, whether youre upstairs in the bedroom or halfway around the world, youll be the first to know when the pump activates and if it has any problems.
  • Peace of mind: Lastly, these battery backup pumps offer you something that all homeowners want, and thats peace of mind.

The Definitive Sump Pump Guide

Any building that has an elevation below ground level needs some way of removing water from this area. A basement cannot drain water naturally, so a sump pump is an absolute necessity. Without it, a basement will quickly become flooded, causing damage to your possessions and, possibly, thousands of dollars in repair bills to your home.

If you are not too knowledgeable about sump pumps, this guide is going to explain everything you need to know. Form a basic definition to what a sump pump is, all the way to installation and the details pertaining to battery backup sump pumps. Ill be giving you the low down on these valuable household safety devices.

What is a sump pump?

Because a basement cannot naturally drain itself, runoff water can easily accumulate. Water may also seep into the basement from external drainage, the water table and, sometimes, even the drains inside the home. Being the lowest point of the home, all excess water will eventually make its way to the basement.

To prevent the basement from flooding, a sump is built. This is a small basin that is situated below the floor level of the basement. All water that collects in the basement will naturally flow into the sump. In order to remove this water from the sump basin a sump pump is used to lift the water out of the basement sump to a place where it can drain naturally and safely.

Maintaining Your Battery Backup Sump Pump

With any sump pump you need to occasionally check that there isnt too much debris in the sump basin and that all your pipes and fittings are in good condition. When youre using a battery backup sump pump, there are a few additional maintenance procedures that you should be aware of. This is not time consuming or difficult to do.

Id recommend doing a system check at least once a month in the rainy season. If you have water in your basement all year round, do this every month. All you need do is switch the main supply to your primary pump and check that the battery pump is functioning properly and that all warning systems are working as they should. When you switch the power back on, make sure the battery is charging by checking the control box charge indicator.
