Have a problem with debris in hot water only in residential application. Roman Tub filler does not have an aerator and debris is alway showing up when running hot water. Have changed anode rods to aluminum and still have debris, it's just a lighter color debris than the original magnesium rods. We have done extensive water tests and they all look good. We put a 10 micron filter on the main water line coming in and added a water softner just to make sure water quality was high. There are 2 hot water tanks in the system, one wired and the other is a holding tank which is looped through the Water Furnace Geo (desuperheater loop). 4 days ago we removed the aluminum anode rod completely just to see what would happen. Also flushed the tanks. Now, the hot water is yellow, and the debris is just as bad, or worse. Any ideas?
