Well we are very happy with our water filtration unit, but the service / warranty leaves something to be desired. The water spout for our unit has a water quality monitor which quit working, no problem as it is on warranty right? The problem there is that they would not give you the new tap without a house call of 129.00. So now he arrives and confirms it is the tap and states as it is on warranty it will be replaced at no charge for the tap, but the labor is 60.00. So I find out that the tap would cost 100.00 to purchase, but with the warranty it will cost 129.00 for the house call and 60.00 to install for a total of 189.00 ?? for a 100.00 tap that I could easily replace in 15 minutes. So moral of the story is beware of the warranty
