Batteries and Sump Pumps
Back up sump pumps are available in two types: DC and AC/DC. The battery back up system will switch to the DC battery power when the AC power has gone out and/or if your primary pump should fail. Some pumps can run directly off the AC wall current without depleting the battery while the power is working steadily, and other back up sump pumps will run only off the DC battery once the power is off.
Which Battery Back Up is Right For You?
It’s important to note that there is a further division in the types of batteries as follows:
- Deep-cycle maintenance-free batteries, also known as marine batteries. These batteries are sealed so that you can set them in place and not worry about them.
- Lead-acid batteries, also known as wet cell batteries. These batteries so require a bit of maintenance in that you will need to add distilled water occasionally to keep the lead from drying out. Lead acid batteries are most commonly found in vehicles.
Your Float Switch
Your float switch is an important piece as it will trigger your sump pump when the water level rises high enough above your water table. Most switches will come with your pump (primary or battery back up), but separate ones can be purchased and installed to give you that added layer of protection. Smart float switches now exist as well; this technology will send an alert to your phone to let you know something is up – it doesn’t get any easier than that!
Some sump pumps have long been designed with an alarm set to go off if there’s an issue, and technology has improved this feature greatly over time. Similar to the float switch we just described, you now have the option to have an alert sent to your phone should there be cause for alarm.
