Good morning,
So you will not need to worry about the flow going into the 1800RETRO as that is not really how it works. The inlet pressure that the 1800RETRO can handle is 15 to 70 PSI which you should not be going over or under. Therefore, the 1800RETRO will then convert that PSI to 30 PSI as it has a built in pressure regulator. It then supports a flow of .5 - 6 GPM depending on if you use emitterline or some sort of outlet device after the 1800RETRO.
So the flow is only referring to after the 1800RETRO if that makes sense.
Hope this information helps! Here is a link to the spec sheet in case you need to see it - https://www.rainbird.com/sites/defaul...
