Many knowledgeable homeowners choose to maximize the protection against foundation damage and basement flooding provided by a sump pump system by installing a backup sump pump. Adding a backup sump pump provides an additional level of insurance against flooding and foundation damage. In the event of a sump pump failure, the backup sump pump will take over and pump out the water until the primary sump pump can be repaired.
Backup sump pumps are designed to operate without the need for household electricity so they work in the event of a power failure. There are two basic types of backup sump pumps. One design uses household water pressure to operate while the other design relies on a battery for power.
If access to a water supply line is not a concern, a water powered backup sump pump is an excellent choice. They need very little maintenance and can run almost indefinitely. They are not a good choice for homes on a well that use an electric well pump. In the event of a power failure, there would not be any water pressure to operate the pump. Also, these pumps have to be connected to a pressurized water line. If there is limited access to nearby plumbing, installation of the water line can be a problem.
If installation of a water powered pump is impractical or too expensive, a battery powered backup pump might be a better choice. These pumps use a dedicated battery that is kept topped off with a small battery charger. There are few installation concerns with these types of pumps, but they unlike water powered pumps, the battery requires regular maintenance. In addition, they will only run until the battery wears down.
