  1. Backflow prevention • Why the changes? • Greater emphasis on protection of the water supply • FDA also focuses heavily on product protection • In some places it may have been overlooked.

  2. Placement of Backflow Prevention Devices on Plate Coolers • 5 or 3 point debit • 5 Point Water Protection • 3 Point Product Protection

  3. PLATE COOLER – NO SUBMERGED DISCHARGE – NO BY-PASS WATER AND MILK PROTECTED OPEN TO ATMOSPHERE (NO SUBMERGED OUTLET) POTABLE WATER SUPPLY

  4. PLATE COOLER – NO SUBMERGED DISCHARGE – BYPASS WATER & MILK PROTECTED OPEN TO ATMOSPHERE (NO SUBMERGED OUTLET) POTABLE WATER SUPPLY

  5. PLATE COOLER – NO SUBMERGED DISCHARGE – SEPARATE BY-PASS WATER & MILK PROTECTED OPEN TO ATMOSPHERE (NO SUBMERGED OUTLETS) POTABLE WATER SUPPLY

  6. PLATE COOLER – PRESSURIZED DISCHARGE (VALVE IN LINE) WATER & MILK PROTECTED PRESSURIZED DISCHARGE – ball valve in discharge line, solenoid valve in discharge line, non-siphon stock tank float at end of line, etc. POTABLE WATER SUPPLY backflow preventer required in supply line

  7. PLATE COOLER – PRESSURIZED DISCHARGE (NEW REQUIREMENT) WATER & MILK PROTECTED POTABLE WATER SUPPLY backflow preventer required in supply line and in by-pass line PRESSURIZED DISCHARGE ball valve in discharge line, solenoid valve in discharge line, stock tank float at end of line, etc.

  8. PLATE COOLER – PRESSURIZED DISCHARGE WITH SUBMERGED INLET WATER & MILK PROTECTED SUBMERGED OUTLET Line submerged in stock tank, float mounted below flood rim of stock tank, etc. POTABLE WATER SUPPLY backflow preventer required in supply line, if outlet is pressurized Backflow protection required

  9. PLATE COOLER – PRESSURIZED DISCHARGE & SUBMERGED INLET WITH BY-PASS (NEW REQUIREMENT) WATER & MILK PROTECTED PRESSURIZED DISCHARGE WITH SUBMERGED OUTLET Discharge line with valve; line submerged in stock tank, float mounted below flood rim of stock tank, etc. POTABLE WATER SUPPLY backflow preventer required in supply line, if outlet is pressurized & in by-pass line, if outlet is pressurized (float, ball valve, etc.) Backflow protection required

  10. Other Backflow device issues • RPZ Valves require Annual Testing and Documentation • Tag on the RPZ • Or Sheet or Log signed by certified tester
