After reading some of the technical problems that people have with their sprinkler systems, I'm not sure, but my question may seem silly.

I've had to replace a few of my Hunter PGP rotor heads. One of them I replaced with a Rain Bird 325AS. I'm beginning to think it puts out less water per min. than the Hunter PGP. I'm having some dry spots in the area where the Rain Bird irrigates. Should I be sticking with the same make heads throughout?

Thank you for your response.
