What it delivers
The QwikProducts QT7712 Tankless Descaling Solution is a descaling solution for tankless water heaters.
Descaler goes in the flush bucket in place of (or with) vinegar and is circulated through the heat exchanger by a flush pump.
Makers differ here. Rinnai's procedures use white vinegar and say never to use chemical solutions; follow your own heater's manual.
