Are Battery Backup Sump Pumps Necessary?

This is a very common question among homeowners that are hiring a contractor to install a new waterproofing system. Often the contractor will sell them the pump giving them no idea of how to service or maintain them. Overall battery backup sump pumps are quite finicky beasts. Batteries and water are not great pals to begin with. Most pumps come with alarms that will sound if the pump is low on charge. The problem is with enough of these soundings the alarm itself dies. Then when the power goes out (and your in Hawaii) your basement floods and guess what doesn’t kick on? The battery back up!

The best bet is to install a sump pump with a self contained trickle charger that will recharge the battery naturally with the flow of water. Ask your contractor about this and they will look into it/learn about them. Anything less than this will certainly result in a mess.. eventually.
