The install went very easily, and it is working well. My water was at pH 5.4, and now it is above 7.5, and it tastes great.
On thing I would add to the instructions; mention the O-Ring between the control head and the tank. I got my system installed and operating. As I went to dispose of the packaging, I found the 4″ O-ring under some of the packaging, in the box. I’ll wait to install it until I get a leak, or I need to take the head off for some other reason.
