Get a Brita filter. I have a 1.5 gallon jug with a Britia filter in it. It helps a lot. Then get a bunch of plastic milk jugs. Wash them out, and put the tap water in them. Let it sit for at least 4 hours, preferably over night, then through the filter. The Chlorine and Florine will leave the water when left in the open over night, and the filter gets the rest.Water.
I miss my parents water (or hard water in general) so much. I have gotten to the point I can't even drink the water at my house. It smells like a freaking pool.
