Pipe Rise and Drop Wrong Size

I had a job the other day and my pipe rises were gigantic!

These are the annotation symbols in single line. To fix things, click on the little angle arrow next to the Plumbing and Piping group label and ensure annotation scaling is being used then change the Pipe Rise/Drop to a smaller scale. Fittings can be changed separately.

You may find that every time you change to a smaller scale it reverts back to the original scale. This is probably being caused by the fact that units for pipe size do not go to a scale that precise. To change that click "Project Units" on the Manage tab, set the discipline to "Piping" and set the rounding to the required precision.

Now take a look at your symbol. Hopefully, things have gotten a lot easier to read.
