Regarding PH, for soil grows it's possibly the most over hyped issue. Unless you're heavily acidic which is highly unlikely for tap water (we have to be able to drink it ya know) I would just roll with the tap water and call it a day.
Talk to any big monster outdoor grower and they will tell you they all use tap water with no PH adjusting. Plus adjusting PH on a small scale is a bitch.
I think my PH tap water is near 8. It' a little on the basic side but so what.

Until you go hydro or something don't worry about your PH too much. Def find out what it is.
Go to Kelly's Pool Supply. They are a national retailer they test water for free. Get your tap water there ASAP (as soon as poured) as PH changes with time.
