PACKAGE CONTENTS
PERFORMANCE
Pump capacity will vary due to inlet water pressure, working
water pressure, discharge elevation, number of pipe ttings,
inlet and outlet pipe size, uid viscosity, degree of water
clarity and water temperature. The ow rates in the chart are
approximate values.
NOTE: Some districts may require a reduced pressure principle
backow preventer per ASSE Standards 1013. Check local
codes.
