 So this is the first filter system here? Correct. So the way the softener works, as the water comes in from your pressure system, the water comes down and the first thing it hits is a 20 micron pre-filter. We're gonna capture any sediment, silt, sand, or anything in the water. 20 microns are larger, protecting the inner working components of the valve and protecting the media and everything inside. One tank is always in service while the other is in standby. So when one tank is exhausted and you are out of your softened water, this system will regenerate immediately. My skin, I'm telling you, the hard water that I've had in my house, my skin is so rough. I'm looking forward to this. I'm really excited because not only do I get to shower again, I mean, I get to have clean water. I don't have to worry about the hardness in the water, like in my humidifier, not to mention the hot water heater that I've already replaced because of scale, hardness, ridiculousness.
