Why do my pipes creak 10 minutes after using them?
I don't see why not.

The creaking is caused by the pipes rubbing on the joists as they expand and contract when first the pipe heats up as hot water runs through and then cools down as the water left in the pipe cools down.

If you wrap the pipes in insulation this will have the dual effect of stopping the creaking and keeping the hot water in the pipes warmer for longer.
