It is not uncommon, while inspecting roofs, to find the test caps still in place on plumbing vents. Part of inspecting the original installation of the plumbing system for leaks requires that all openings be capped off. After the test, the test caps are removed so that the plumbing system can function properly. Here is a picture of a test cap I found still in place on a roof—-most likely it had been there since 1980 when the building was built.
Even 30 years later, the “instructions” for how to remove the cap are clearly visible. Given the “obviousness” of the instructions, I got a good giggle out of how the problem was resolved—-as shows in the next picture.
Holy vent pipe Batman!
Sometimes it is difficult to figure out the thought processes behind how things end up the way they do, and fortunately, as inspectors, we do not really have to. It sure is good for the funny bone however.
