You are welcome. After I decided just how much R.O. stuff I really needed, I started looking at all the home improvement and hardware websites To see if I could to a cash transaction in person to eliminate a paper trail. I hate that the gov’t can find out everything you do with your credit or debit card without even a warrant. I saw the Home Depot had the biggest selection of R.O. systems available through the website. My mouth dropped when I saw they had 2 systems that will add cal/mag. I bought the Gardener version. The kitchen version included a faucet, pressure tank and float controlled pump. It was more expensive by the cost of the included hardware.
I was buying for my grow water so I didn’t need the extra hardware. It was very easy to setup. It comes with an female hose end attachment so I screwed it on to my basement sink faucet and used it that way until I decided where and how I wanted to permanently mount it.
Making pH water shouldn’t be as hard as it is with r.o. and this system solves that problem. 
Edit: Distilled water acts the same as empty r.o.water, in case you ever have need to know that.
