David Meiland Posted September 29, 2016 Report Share Posted September 29, 2016 Saw this today in a 2004 house. The copper has aged to an odd color, especially the flex connectors. Washer and dryer are in this room, which is in a walkout basement. Any explanation for this? Click to Enlarge 82.23 KB Quote Link to comment Share on other sites More sharing options...

David Meiland Posted September 29, 2016 Author Report Share Posted September 29, 2016 I was wondering about that. There were no laundry machines installed (they are being replaced), but the connection for the dryer vent looked poor, and I suspect a fair amount of the exhaust air ends up in the room.

Jim Katen Posted September 29, 2016 Report Share Posted September 29, 2016 You don't even need it to be in the exhaust. An open container is all it takes. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted September 29, 2016 Report Share Posted September 29, 2016 I had one house with a well and chlorinater where all the copper was black. Even the brass valves on the boiler were darker than your pics. Quote Link to comment Share on other sites More sharing options...
palmettoinspect Posted September 29, 2016 Report Share Posted September 29, 2016 Yep, looks to be the same type of corrosion you'd typically see under a bathroom sink where all the cleaning chemicals are stored. My wife spays this clearer (Scrub Free) on the tubs to clean them and they eat the drain to the point where it needs to be replaced. Works great at cleaning the tubs though.

Wow Jim I love a lot of your posts I never would have thought of that but it makes sense. If it does that to pipes just think what it does to us!!!
