He was able to take a look the equipment to determine the amount of bags needed and tested the water to make sure that the system was working properly and answered all of my questions.
Reliability. I was able to ask all my questions when I had a consult before getting the service. Since I signed up the service has worked pretty much like clockwork. I don't usually need to be involved unless I have a question or want to make a change. For a basic item like water I like that.
