I have a 12 year old house. The past couple of months a couple of hot water pipes have sprung pin-hole leaks at the solder joints. This has happened on four separate occasions.
I've had three different plumbers look at it .
- One thought just coincidence or bad luck.
- One suggested perhaps a bad ground. Disputed by the other
- One suggested water quality. Water was tested and appeared fine.
Wondering if anyone would have some thoughts / suggestions?
To update, the cause was a hot water re-circulator. Apparently the flow of water over the course of years can erode the solder around the pipe joints. The hot water fittings were replaced and a timer put on the re-circulator to run only in the mornings.
