If your tap water is bad you may find it best in the long run to invest in a inline water filtration system. You could probably find one for under $100.

Now I've read from a few places that say distilled water makes sense in a small grow situation. Surprised to hear you say this. Perhaps spring water ?

I'm very paranoid about what is in the water these days, from pharmaceuticals to toxic waste turned fluoride synthetic.
