Pin hole leaks in copper pipes

15 years ago

My home is 3.5 years old. Recently myself and my neighbor (his house is 6 months older) began experiencing pin-hole leaks in copper elbows. We had the same builder, plumber, electrician for both homes. Copper elbows tested by manufacturer who blames poor installation (too much flux). Plumber blames electrician claiming that system wasn't properly grounded. We have each had about 8-10 leaks. Both started near hot water heater. We both have recirculating pumps (we switched them out from cast iron to stainless steel). I don't trust this system and think plumber should re-plumb. Don't know where to turn with everyone pointing fingers. Any thoughts? Thanks
