Not at all. Plumbing can be very complex, digital ot otherwise. It's not as easy as "connect input to output and done", there are constraints on the system that need to be accounted for, and meaningful design decisions to be made especially with respect to expected volume.

But that doesn't mean it's creative. Plumbing, like web development, may have all of these complexities and constraints, but typically there is really only one solution that can be considered "right" and your job is to go through the steps and do the math to find it, there's not a lot of room for creative thinking, despite the complexity of the problem.
