Hunter MP Rotators

Can I use 30PRS heads and 40PRS heads on the same zone with Hunter MP Rotators?

I would say Yes, because the precipitation rate for all MP Rotators are pretty close regardless of the pressure.

(See Nozzle Performance @

The precipitation rate (with square spacing) for most MP Rotators is 0.39"/hr at 40psi, and 0.43 at 30psi.
