What is a Backup Sump Pump?

In our last blog post, we talked about sump pumps, what they are, what they do and how they work. Before you keep reading, make sure you check it out so that you can get the most out of this week’s blog post as well.

Now, you might be thinking wait, there’s a backup sump pump, too? The short answer is, yes! If sump pumps are what keep your home dry and protect it from water damage, then the backup sump pump is your primary sump pump’s insurance policy; it keeps working when your primary sump pump might fail due to a power outage or even because it’s overwhelmed by too much water.

Why Do Homes Have Backup Sump Pumps?

The majority of primary sump pumps are hardwired to your home and run off of its electricity, the same electricity that powers your lights, your appliances and much more.

If a big storm comes through and knocks the power out, this can of course cause an electricity-powered sump pump to stop working, which in turn can potentially lead to a flooded basement or other water-related problems. Therefore, many homeowners opt for a battery or water-powered backup sump pump in case their primary sump pump fails or becomes overwhelmed.

Most primary sump pumps do have a battery backup of their own in case of electrical failure. However, having a totally separate backup system provides your home with additional protection from basement flooding and other issues, such as clogs or blockages, that can cause sump pump failure.

A backup sump pump can also assist the primary sump pump if and when it is overwhelmed by large amounts of water from a particularly severe storm.

Different Types of Backup Sump Pumps

Backup sump pumps are installed next to the primary pump, and they have their own float activation switch (the level sensor that alerts either pump of rising water levels in the sump pit and activates the pump to turn on).

The water line trigger for the backup pump is usually set slightly higher than the trigger for the primary pump so it works as a true backup option if and when water levels become higher than what the primary pump can handle.

Backup sump pumps are either battery-powered or powered by water to ensure that they stay working during power outages to continue protecting your home. While battery backup pumps are a common option for many homeowners, water-powered backup sump pumps run off of water pressure. So, they keep working even if your home is going through a longer power outage that might even outlast a battery.

To determine which type of backup sump pump is right for your home, consider consulting a licensed plumber for a professional opinion.

Should I get a Backup Sump Pump?

Backup sump pumps are totally optional but the general consensus, and the advice you’ll receive from most plumbers, is that you should definitely have one. When you consider the damage that can be caused by basement flooding, the choice to install a backup sump pump, even as a “just in case” option, is worth it.

Similar to primary sump pumps, there are numerous factors such as climate, home elevation, previous experience with moisture issues and the work that you’ve put into your basement that could help determine whether or not a backup sump pump is the right choice for your home. However, you should always consult with a professional plumber before making this decision.
