I am a subcontractor for a home builder in Michigan. We use to install Bradford White heaters in all of the homes we plumbed. The problem started with some tanks leaking within a year after installation which I am responsible for the service call and the damage it does. We hard plumb all units with a union to the hot and cold water inlets. Changing Bradford heater anodes can't be done unless we put a flex line in which adds to the cost plus we have to order them since no store carries them. We switched to a Rheem system in all our installations and actually get better pricing. Now to the anode. I installed a D/C voltage monitor on the first system I installed in our home figuring I would check it out before I made a offer to my main contractor to install this type of unit. I purchased 4 other units from Amazon and tested them for 3 days each. My readings of the power going into the tank were: .9 volts .4 volts .5 volts and this product at 1.9 volts. It is worth mentioning the 1.9 volts fluctuated at times from 1.5 to 2.3 and back down, I use a water softener that cycles every day and figure the salt is a factor. The other products I installed for testing voltages remained the same. Conclusion. I am convinced that this products power supply is "smart" as the website says meaning it raises and lowers current based upon the electrical potential of the water. I can't speak for every customer or contractor but I can say I have not had a problem since I started implementing this product in my check list. Andrew
