The pH has changed or not. Maybe pH has been 5 during a lot of time and you haven't noticed. Have you noticed the problems at the same time you change the pipes? You must investigate what is happening. To adjust the pH I prefer sodium bicarbonate food grade. Strong alkalis have chemical dangers and are more dificult to manege and achieve a fine adjust. The pH curve change very quick with these products.
