What is the best battery backup sump pump system for your home and why?

After a catastrophic flood, I need to purchase a backup system. Please only respond if you know what you are talking about.......a contractor or plumbing professional.....Thanks!

any brand , and a large GPM rateing, [gal per min] just be shure to add a solar panel or a good battery charger to keep the battery in top charge, and test it once a month,

why because if the power goes out and it is flooding the basment theres a way to pump it out,

The companies I recomend are RPT, the RPT-50 model and Eagle, the Eagle 1 Battery Back-up.

you can check them out on-line.

Both have high amp ratings, can add solar panels or trickle chargers for the battery lifecycle.

The best requires a lot of input as to your needs. How much are you willing to invest?estimated time pump will have to run on battery?estimated gallons per hr ? How high will the pump have to lift ?

Check the sight below good information:

the best thig would be to use the same 12 volt sump pump they use in boat bilges, you can keep a trickle charger on the battery all year long and it will pump just as well as a regular sump pump. Buy good deep draw battery and it will last for days after a power outage. A good battery back up or UPS

can cost as much as 5000.00 dollars and will only last and hour or two at most

You want a battery backup that uses a deepcycle battery and solar panel charging.

A cheap generator is always a handy choce too in case there is no sunlight.
