Blue nozzles are just part of a sprinkler "beauty contest" that is going on these days. Even coverage has nothing to do with it. Every nozzle with good-looking close-in coverage is way overwatering that area. Ed Hunter got the nozzles right a very long time ago, and it takes someone overdrawing a water supply, and running heads at less than 30 psi or so, to get poor coverage from PGPs.

Here is what I can share off the top of my head. I am not looking at any charts so I may be corrected. The Blue nozzles are numbered with the gallons per minute on the nozzle like the rainbird nozzles for their rotors. The Red Nozzles on the older Rotors were not like that. What I generally do for residential is use 2 Blue for half circle, 4 for full circle and 1 for Quarter circle blue. This is matched precipitation with gallons per minute in a residential application. This is off the top of my head.
I have seen contractors that did replace the red nozzles with blue nozzles using the same number of the red corresponding to the new blue nozzles and that will kill every system that was designed to its capacity. I recommend that you avoid doing this.

Good Luck :thumbup: :thumbup: :thumbup: :thumbup:

There is not one competent professional that requires the blue nozzles to get good coverage from a PGP sprinkler.

I guess they could throw shorter.I thought the new blue nozzles had a better pattern for total coverage more similar to the rainbird rainjacket pattern.I thought I would try them out but I did not know that it would affect my system.I would like to try them but I am unsure how to match them up for replacement as I am not an expert on these things.

Can the system stand having the heads throw a shorter distance than they do right now? Standard PGP nozzles are just fine, so long as you have the correct ones installed.
