No, you are supposed to save nozzle trees from the cases of PGP's you install.
True but it does not matter. He wants many of the same kinds...The Blue nozzles are nothing special other then a up-sell for Hunter vs Rainbird...
He can buy a blue nozzles cheap online..I still use the red ones since I have cases of them and they work just fine.
Ps. Most installers, rip off, will NOT give the homeowners the nozzles since it cost them most...
