Leaks in hot water circulating system
This system is about ten years old and six leaks have occurred in the last two years. All leaks have been in the 1/2" copper return line at or near joints. The return to the gas water heater is at a check valve at the cold water inlet. One plummer suggested that it might be electrolysis. One leak occurred at the water heater and the others several feet away. No leaks have occurred in any of thr other copper pipes. Any suggestions?
