Closed Cell spray foam and wet return pipes

Greetings all!
When I was getting my basement remodeled and was way more ignorant than I am now I had closed cell spray foam applied to the basement walls. Now, the original wet return lines were in poor condition so I had those replaced. My concern now is if the spray foam that was applied over those wet return lines will cause problems down the road. When it was getting done at the time I didn't think anything of it or knew very little about my heating system. thx

    It might. Then again, it might not. I wouldn't worry about it. The biggest single problem I can think of would be the possibility of a leak in the wet return which you wouldn't be able to see as easily.

    Is the spray foam of the close cell variety? If so, it may actually protect the lines from external corrosion.

    What material was used for the new wet returns?

    Jamie,

    The spray foam is the closed cell type and the material to the best of my understanding is black steel piping.

    I daresay if you are talking about new black pipe wet returns, then you won't be living at that house when a problem occurs.
