Advice needed! My husband found and removed a small section of pipe from the kitchen wall after removing some boxing where what looks like an old boiler was. He has said it slid out from the wall easily and was fully in tact and in good condition. However I'm just worried about the potential dust or particles that may have been released from doing so. Is there any need to be worried? any advice on what I should do next, is it worth arranging a test to be carried out on the pipe for peace of mind?
