I had a newly installed system 200 furnace with hot water heater around a year ago. I recently noticed that there is a green residue peeling off the pipe going into the hot water heater. I called the plumber who installed it but have not heard back. Is this something i should be concerned with and if so is there a fix without calling out another plumber?
It looks like the copper joint was not sweated properly and is leaking. You'll want to get the plumber to pull the coroded pipe (the green is what copper corosion looks like) and sweat a new pipe in there
If you want a DIY solution
- Shut the water off
- get a pipe cutter and cut the pipe off just before the elbow
- Buy some Sharkbite push connectors and replace the coroded section with PEX. Will probably run you about $20 (not including the cutter)
Make certain the PEX and connectors are the same diameter, and that your water heater is not putting out water above 180 degrees
