Are rotors ok at 30 psi?

Do rotors perform well enough at 30 psi? My volume is 12 gpm. I am drawing from 1" indoor plumbing connected to a well. The pump is in the well. I am worried that by the time i run out to the heads I will only be at 25 psi. What are my options to increase pressure while maintaining my volume?

A booster pump would keep your pressure up.

You gotta have PSI to throw the water. Check the nozzle tree for the make and model.

What is the cost of a booster pump? If I add say 20 psi to bring the pressure up to 50 psi, will I still be at 12 gpm?

A booster pump is about $150. It will bring your pressure up, gpm is dependent on well pump so that would remain the same.. Booster will go on irrigation side.

Exactly...or a slight fluctuation (shower, toilet flushing or other demand) will decrease your pressure and spray patterns.

Still need to know how big an area he wants watered. I would not put an irrigation system on a well I used for drinking water unless I knew I was not going to run the well dry. What is the recharge rate of the well and how much area is to be watered. Type of grass and so forth.

The well production rate is 40 gpm. If I do not go with a booster pump, will the heads be ok with 30 psi static pressure at the source? Also, when you say design the zones at 10 gpm max, is that regardless of whether I use a booster pump or not?
