Any tips for fine-tuning pipe pitch?

I've been checking out the pitch of all of my steam mains, and I've discovered that my slowest main is sagging. It doesn't hammer but my level shows that the pitch is off in a few spots. It looks like the previous owners cut most of the hangers for some unknown reason. I've restored the missing hangers, but I have this existing one that I need to raise just a little bit. I've considered removing the bolt and moving it to the next hole up, but I think this might move the pipe too far. Are there any better ways to adjust the pitch?

    Can you get under the insulation, under the hanger and put in some shims?

    Good call--I could easily remove that insulation and see if there's room. I do remember that this hanger is tightly wrapped, though, so there might not be much room for shimming.

    You can also buy an adjustable pipe hanger (clevis hanger) and mount it in that are. It has a pipe loop that screws onto a threaded rod and you can adjust the loop up or down as needed by turning a nut.

    Thanks, Fred. Sounds like a great idea.
