With your purchase of a Care-Free Conditioner, you will need one of the following power supplies.
When installing into a copper or gal pipeline such as a water meter, EK1 can be used.
The magnesium rod will create an electrical current to the conditioner, provided the copper or gal water pipe is located underground.
When installing into a PVC or poly line EK2 can be used.
The magnesium and copper rods act like a small battery and create an electrical current to the conditioner.
