When we first brought this system home, we were so happy with it. the tap water in our area is questionable at best so it was very nice not having to stock up on water every few days, we are also expecting so its a big weight off knowing my wife is getting the best water she can. Here is where the bad part comes in, WE HAVEN'T EVEN HAD IT 3 WEEKS and the filter has already gone???? All yesterday it was fine, then I filled it up before bed, like I do every night. Then when I get up to get some, it tastes like battery acid. My wife checks it this morning and it jumped all the way up to 189! After it was at zero, just yesterday! I mean seriously? if it was months old than sure, I would understand. But it isn't even a month old. Was this filter defective or??
