Hi Y'all,
We finished our design, but we wanted to lower the design pressure for some heads. When we did so, all of the arcs defaulted to the non-adjusted arc which now shows them over-spraying onto the pavement significantly. We show our design arcs in our final drawings so that the contractor can adjust as we have shown (and to prove that we have coverage). What should we do now? We need to dial the arcs down so they are not shown over-spraying onto the street.

Jer,
That only worked PERFECTLY! This is since the whole median that we were treating was a uniform width. Thanks for the great suggestion. Now that was something that I expected from you.

You can use Move Piped Equipment to address this.
After clicking on a head, use the A and D keys to adjust the radius as desired, and then Right Click to put the head back to its same spot with the newly adjusted radius.
This sounds like it also might be a great case example of why Schematic should be used on every project. Hopefully with that area placed as a Schematic zone, the design pressure issue could be addressed long before all of those heads were placed and piped.

We’ll, thanks Jer. Obviously I’m not going to resize the radius of the hundreds of heads. I just wish that by adjusting the head pressure it wouldn’t disregard the previous manual adjustments and revert to the default non adjusted arc. Oh well. I guess that I should have used schematic design first. We’ll have to not show the arcs for this project. Thanks and have a good rest of the week.

One thing you could try, is to set a radius reduction percentage when selecting the new design pressure.
I just assumed that after changing the design pressure, that any number of heads would need to be repositioned or changed to a different nozzle. It's rare that changing design pressure is a "click it and done" sort of procedure.
But it's also something that helps for us to have the drawing, to see if we can come up with a better workflow. I would imagine that in dropping from an average of say 85% radii for 30psi heads, down to 25psi, that one would want the full 100% radius. As such, it's by design that the system restores the radius distance to 100% when changing pressure.
