Our water is quite good except if they flush pipes or something.
FYI, Most fish shops will test water for you (or at least here they do). I rarely test much anymore but usually check tap water every season change (they change water supply here). Main one I do is nitrate and phosphate for planted tank. Also I test after big filter cleans or tank all-nighter re-scapes
