High Volume Backup Sump Pump with Vacuum Breaker

High volume water powered backup sump pump with Atmospheric Vacuum Breaker for back-flow prevention, removes 1,000-1,400 Gallons per Hour of sump water using your home's water supply. It includes a battery powered high water ALARM and safely protects your home's water supply from back-flow. With no batteries or chargers, there is nothing to wear out or replace. Once installed, it will last a lifetime with zero maintenance. On top of all that, many areas require back-flow protection for these devices and Basepump HB1000-AVB has what you need. Make sure you can fill a 5 gallon bucket at your outside hose spigot, without the hose, in less than 30 seconds for this pump so you know you have enough water flow to feed it properly. When testing your water supply, if you have a water softener, filter, or frost-proof spigot, the test will be inaccurate. This model MUST be installed using a separate discharge pipe to the outside.
