If you determine that the pinholes in your copper pipes have been caused by a ph of 6.2 and you have corrected the problem with a neutralizer; must all of the pipes now be replaced, or will the neutralizer stop the corrosion in its tracks and prevent future pinholes?

The correction will slow the erosion but may not totally halt it. In other words, don't be surprised at a few more pinholes down the road. Much depends on the present state of your copper plumbing right now.

It should stop further degradation, but will not cure whatever has already happened, therefore there is no way to give a good answer. Some spots could be deteriorated to the point that it will only take a small amount of erosion to cause a leak.

ditto above answers
plus
ideally the water should be SLIGHTLY alkaline for best Cu life (7.4 is perfect just like a swimming pool)

Thanks guys, I kind of thought that would be the answer. The house is my son's house that he purchased 3 years ago. Its 30 years old and its the money pit. Evidently the ph of the well has been low since it was built, but has never had a neutralizer. we are rehabbing the entire house. unfortunately we are past the sheet roc stage.
It looks like the only way I can be sure that my son won't come home one day and find serious water damage is to replace every pipe in the house.
