I've heard there can be a few causes to pipes that develop pinhole leaks . Most of the time I see this phenomenon , it's almost always the hot domestic pipe . And always towards the bottom of the pipe . This job had pinholes on the cold pipe going to the oil fired heater also . But nowhere near as severe as the hot pipe . The heater and pipes were 10 years old . Could something be happening to the water after it heats up to cause the pinholes ?
