Called and set an appointment up for 2 pm, it is now 7:15 pm and nobody has shown up. Called every hour only to be told that someone would be there in an hour, customer service sucks. I had new copper pipes put in my home with this water filter and it does not work properly, *** water all over the basement. They got their money and now I have to wait like everyone else who has paid and now considered second class. Very short with you when you call like you are bothering them. Go somewhere else for a plumber.
