Whitlam FLOW-KIT Flow-Aide Complete Descaler Kit
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.
