I purchased 2 of these units in June 2020 to replace 2 units of another name I purchased on Amazon that was turning my water a yellow/orange tint. I checked the power output to the anode on both units and got a reading of only .03 volts which tells me the both power supplies could not keep up after 4 months even though the bright green LED was lit. I have an AO smith 40 gallon and a Bradford 40 gallon. After the installation the Bradford tank power supply LED stayed red and would not turn green even though it was hooked up per instructions. I contacted Matt and after some photo exchanges I had to change the Bradford tank T setup to a smaller pipe length coming out of the tank. After the change the LED turned green in about 4 seconds and has been working fine since. After installing these units, the water has returned to clear once again. One power supply going to the Bradford tank is now 1.8 to 2.1 volts and the newer AO smith tank is 1.0 to 1.2. Very pleased with this product and the customer service.
