Rick, there are many theories regarding what causes internal corrosion in copper piping. You may re pipe with copper and have the same problems all over again. You treat your boiler and cooling tower water to prevent scale and corrosion, why not treat your potable water with a phosphate feeder. Check out http://www.aquasmartinc.com they sell these types of products. You also might want to talk to Bud at Suncoast plumbing, http://www.copperknight.com he sells a cathodic protection device.
