(Also, I know how to install push on pvc, but welding PE for a pressure...- Sterilecuckoo58

Calibrating a model in WaterCAD using Flow Test Data
There are two things flow tests are good for - approximate assessment of system condition and identification of gross inadequacy. To perform the assessment on paper you need two flow rates and two pressures. Doing the test during the day means you have background flow, do it 3 a.m. and you may...- Sterilecuckoo58

Pump operating outside the characteristic curve
Don't extrapolate a curve... there's a reason the pump manufacturers stop drawing the curve where they do.

Submersible pumps and Vertical lineshaft turbine pumps
To learn about pumps and pumping stations I would suggest "Pumping Station Design" by Jones, Sanks, Tchobanoglous and Bosserman... the book is eminently readable (not a snoozer so don't use it as a sleep aid) and you'll learn plenty. Then you have a more focused approach to your assignment...- Sterilecuckoo58
