If you depend on a sump pump to protect your home from flooding, experts recommend installing a backup sump pump that will kick on in the event that the primary sump pump fails due to a mechanical issue, a clog, or power outage. Your primary sump pump will get the job done the vast majority of the time, but a backup sump pump is essential for the best, most reliable protection against flooding
When choosing a backup sump pump, you have the option of a battery powered backup pump or a water powered backup sump pump. Each type has its advantages and disadvantages. Your plumber can help you decide which type will work best for your situation.
A water powered backup sump pump uses the pressure from your municipal water supply to power the pump. These pumps need no electricity and are not affected by power outages. They are also very simple and reliable pumps that can be depended on to operate properly when needed. They are plumbed directly into your household plumbing and don’t have any batteries to keep topped off.
Water powered emergency sump pumps are not a good choice if your home is not connected to a reliable municipal water supply. For example, they are not recommended for use with homes that use well water with an electric pump. Also, in some homes running the water supply line can be a problem. These pumps are usually installed in the basement ceiling and if you have a finished basement with limited access to the ceiling, a battery powered pump might be a better choice.
If a water powered pump will not work in your home, then choose a battery powered backup sump pump. These pumps are designed to run on a standby battery and can operate during a power outage. They are connected to an automatic battery charger to keep the battery full and require some battery maintenance. However, they are easier to install than a water powered pump and are typically capable of pumping a larger volume of water.
