if you have a sump pit, it is a good idea to have a battery powered backup
pump. It costs 200 dollars but can save you lots of headache.
it can help if
1. there is power outage, which is possible if there is a thunder storm when
you need pump the most
2. there is lots of rain and it overwhelms your main pump
3. main pump just failed
don't wait until you got water in the basement to think about backup.
