I was using water from our fridge. It has a filter in the fridge itself, as well as one where the water line meets the fridge. The filter in the fridge is no good anymore, and its ridiculously expensive to try to replace, and a replacement isn't even guaranteed as the model we need is no longer made. My dad said it will be fine since there is the main filter, but I'm not convinced. I had filled up a gallon jug (previously had the Walmart Nursery Water in it, but that is long gone), and after 2-3 days, the water had a weird smell. I will not give my chins that water. So I have been filling their water bottles up with bottled water (Walmart's brand, Great Value).
How can I convince my dad that it is not okay, and to either a) buy a new filter, b) buy a filtered pitcher (like the PUR brand), or c) buy a filter that connects to the tap? I tried to bring up all the different 'bad' points, especially since my mom drinks the tap water (it's municipal water) and I'm pretty sure they only filter out the major contaminants, and they add Fluoride.
Any ideas?
