Are you measuring the pH on your tap immediately?
Try waiting for 24 hours and then check...
Golden rule: NEVER let water chemistry worries stop you performing basic maintenance. Way too much emphasis is placed on pH in this hobby when fresh water fish are just not that sensitive to pH...
That isn't to say it can be completely ignored either... just not the primary focus in fresh water.
One way to compensate for low pH tap water is to change the same amount of water per week as you usually do, but do so in many smaller changes as opposed to one or two big ones.
Hope that helps.
