Over Claustrophobia

We admit that we've gotten our money's worth from this picture; it appears three times on our site, each illustrating something different and bad.

What is bad here is a utility room with such a low ceiling that there's not enough room to properly run the vent pipe, so that it pursues a meandering course guaranteed to cause problems. And working space is nonexistent, as well, should someone want to service it for longevity.
