AO Smith TAC Filter

I think a great test for this (we have hard water) was when I used it in the Vicks Steam inhaler wherein it heats the water you give it (should be distilled, but wanted to see what the tap would leave behind). Our water, instead of scaling up the inside of the heating chamber there is floating white stuff that is very small. This is EXACTLY what should be happening. The calcium and such bind with themselves instead of the fixtures or heaters, so if you see them they should be more like a powder. When I fill the chamber all that scale floats up to the top and I dumped it out. Way easier than CLR and a much better way to clean it as well. I am going to go with a tankless heater soon. I will report back on how this does, but I am expecting to need to do more to condition the water. As nice as this filter is, I live in an area where they fracked and blew up the landscape for natural gas (and pipelines after) so we have a ton of minerals in the water from it being disturbed below many years ago, but the water still has high amounts of various components. I have noticed the fixtures are staying clean as well, and I just replaced them so it's easy to see build up.

Since I happen to have Pex starting at the incoming water line, installation was really quick and painless.
