FAQ
Frequently asked questions
When do I need it?
If your basement or crawl space has a primary sump pump — during a storm power outage, the main pump stops and water rises. A battery backup keeps it running.
Battery or water-powered?
Battery backups work without municipal pressure; water-powered backups use water pressure but need good flow. Battery is more reliable overall.
How long does it take?
Installation takes 3-6 hours depending on the pit and plumbing configuration.
