The water here in Mount Pleasant, NC is notorious for ruining hot water heaters. I was replacing my electric heating element every six months. When I bought the HardnessMaster, my heating element was already six months old. So, even after I installed the HardnessMaster, I was certain that my water heater would still fail on schedule because the element was already completely encrusted to an inch and a half thick. Well, after another six months went by with my water heater working perfectly, I realized that something amazing had happened! The HardnessMaster had actually removed that calcium crust and restored the heating element. My water heater with that same element has been working perfectly, non-stop, ever since! Next month it will be three years since I installed the the HardnessMaster! All I can say is that it is a miracle of technology! What used to be a maintenance nightmare for me before, is now no maintenance effort at all. And it only took me 20 minutes to install it.
