My tap is right at 7.0, however our water system uses well water that's been treated, and has a high chlorine content, but the ppms are still only around 276ppm on any given day. I have very neutral water, but ironically enough, we've noticed that if we pull water from our outside faucet (hose attached) the pH is 6.6, which is very strange considering it's from the same source and we don't have any filters in the house at all.
8.0 is not BAD, since you adjust it, but it's just one of those luck of the draw type things. Sometimes you get fairly close to neutral, others, not so lucky.
I always recommend getting a 5 gallon ozarka bottle or two and keeping those full of water.
Don't forget to let the tap water sit overnight to allow for more chemical evaporation.
