What is a Vacuum Breaker Backflow Preventer?

Basepump models RB750-AVB, HB1000-AVB, and CB1500-AVB come with factory-installed vacuum breaker backflow preventers. These devices automatically protect your home's clean water source from cross-contamination with sump pit water. Here's how they work: In the unlikely event that, while the Basepump is operating, the mu

Practical Considerations in Pump Suction Arrangements

Check valves are installed on pump discharge lines to prevent liquid flow reversal with the succession of pumping. In a similar fashion, a foot valve is simply a form of check valve, usually in a vertical position, usually incorporating a strainer, installed in the pump suction line (see Figure 3). The purpose of the foot
