Flow-Aide System Descaler Safely removes scale, lime and rust from Gas Tankless Water Heaters and all On Demand Hot Water Heaters
Whitlam Flow-Aide System Descaler for Tankless Water Heaters
Scale, lime and rust buildup decreases the efficiency of tankless water heaters and other
appliances. Buildup can restrict flow and ultimately shut down a unit. Flow-Aide System Descaler
quickly dissolves water scale, lime, rust, and other water formed deposits, restoring efficiency
to most all appliances. Flow-Aide System Descaler is a non-acid, non-toxic concentrate which
is certified to NSF/ANSI 60 for use as a cleaner in potable water systems.

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*.
Pour 1 gallon of water into bucket and place under water heater.
Connect one hose to pump, and other end of same hose to cold service
valve. Place pump in bucket.
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.
Connect second hose to hot service valve. Place other end in bucket.
Open both hot and cold service valves.
Plug pump into grounded receptacle. Never allow pump to run without
adequate liquid in bucket or damage to the pump will occur.
Allow pump to circulate Whitlam Flow-Aide solution through heater for
30-45 minutes. Unplug pump.
Close cold service valve. Remove hose from cold service valve, and
replace service cap.
Disconnect the hose from the pump and remove pump from bucket. Discard
Whitlam Flow-Aide solution*.
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.
Close hot service valve. Remove hose from service valve and replace
service cap; then open hot isolation valve.
Connect power to water heater and return appliance to service.
