      • Direct connections to cisterns, hot water heaters, or softeners.
      • Leaky faucets
      • Taps near the ground (to prevent back splashing)
      • Threaded/swing taps
    • Allow water to run for 5-6 minutes to flush out static water. Adjust time based on piping configuration and use.
    • Remove any tap attachments before sampling.
  3. Bottle Filling:
    • Fill to the top to minimize headspace.
    • Seal tightly to prevent leakage.
  4. Storage & Shipment:
