GrateSump™ Plus II Battery Backup System in Rochester, New York

The primary purpose of the sump pump is to suck up any excess water underneath your basement or crawl space floor, channeling it away from your home. It's the best way to make sure that your basement or crawl space remains nice and dry, despite a storm or power outage.

This is where the GrateSump™ Plus ll shines the most, because it has unique features that ensure its place as the most reliable sump pump battery backup system, unlike any other, where basements and crawl spaces are concerned. The GrateSump™ Plus ll is a battery back up system that automatically powers on when power goes out and provides double the work as it is a dual sump pump system. 

The sump pump works normally when your house has electricity, but if there is a time where a storm manages to take out your electricity, it could put you in danger of a flooded basement or crawl space -- just when you need it the most. This is why the GrateSump™ Plus ll Battery Backup Sump Pump System kicks in. When you get this battery backup sump pump system installed in your home, you're giving yourself double the protection and peace of mind, knowing that even without electricity, your basement or crawl space is never in danger of flooding.
