Why not fix a leak instead of removing all the hot & cold water piping in your house? Answer: Like a dentist filling a cavity,sometimes all this does is buy you a little time. When you have hot or cold water leaks, poor flow, low water pressure and other symptoms starting to appear in your home, a whole-house repipe is usually the best solution. Engaging in ‘endless” small repairs, over time will cost you far more than a repipe done in one day.
