  • 1 - 3.5 Gallon Bucket
  • 1 - 350 GPH Pump
  • 2 - 5 Foot Rubber Hoses
  • 1 - Quart Flow-Aide

Whitlam Flow-Aide System Descaler Kit has been designed to work in conjunction with isolation valves that provide 3/4" hot and cold service connections. If these valves have not been installed on your heater, then the heater must be disconnected from the plumbing and drained, and the Whitlam Flow-Aide System Descaler Kit must be connected directly to the cold and hot water connections. Whitlam Flow-Aide System Descaler is NSF approved and safe to dispose of in drains*.

Flow-Aide System Descaling Procedure:
  1. Disconnect power to water heater.
  2. Close hot and cold isolation and service valves and remove service caps.
  3. Pour 1 gallon of water into bucket and place under water heater.
  4. Connect one hose to pump, and other end of same hose to cold service valve. Place pump in bucket.
  5. Add contents of 1 quart bottle of Whitlam Flow-Aide to bucket (Liquid should just cover pump housing). Additional Flow-Aide may be necessary in larger or heavily scaled systems.
  6. Connect second hose to hot service valve. Place other end in bucket.
  7. Open both hot and cold service valves.
  8. Plug pump into grounded receptacle. Never allow pump to run without adequate liquid in bucket or damage to the pump will occur.
  9. Allow pump to circulate Whitlam Flow-Aide solution through heater for 30-45 minutes. Unplug pump.
  10. Close cold service valve. Remove hose from cold service valve, and replace service cap.
  11. Disconnect the hose from the pump and remove pump from bucket. Discard Whitlam Flow-Aide solution*.
  12. Flush tankless water heater for 3-5 minutes or until water flows clear by opening the cold isolation valve and allowing water to exit through the hot service valve into a drain (connect two hoses if necessary) or drain into a bucket. If using a bucket, empty periodically.
