P.S. I am beginner.
1. If you are a beginner, this may be a difficult project.

2. On a water pipe network you have to place your sensor on the far most distant point. But given that the pipes are not 100% rigid, you understand that near your pump, pressure will be much higher than the last water outlet.

Add to that, you have to find optimal values for the P, I and D, you see that it is not as easy as a-b-c.
