Pump suction inputs are often larger than the outputs, since a pump might be lifting water through the suction line, where friction losses could actually stop the pump from working. Lifting water is more complicated than pushing water.

Friction in reverse. Small pipe to large question

I understand the concept of friction when going from a larger pipe diameter to small. However, what happens in reverse?

For example, I have a well pump that has a 1 inch output and I have 1 1/4 sprinkler lines coming of that 1 inch pipe.

Since the well pump has 1 inch output does that mean i will never get to use the extra friction room that a 1 1/4 pipe gives over a 1 inch pipe?

Basically it goes: suctions up the well water via the pump at 1 1/4 then goes through the pump and discharges out of the pump orriface at 1 inch. It gets imediatley converted to a 1 1/4 pvc going to all the heads

Thanks all
