Rainbird 5004 sprinkler range

Hello

I was adviced to use Rainbird 5004 sprinklers with nozzle 1.0 in my garden. When I check the tables, it should get a range of 8.8m at 3 bar.

The shop is telling me, that in reality I would get only 6 - 6.5m range with 5 sprinklers on 1 string (at 3-4bar with max capacity of 2000L per hour).

I’m looking for users who can confirm or deny this. Your help is much appreciated. I’m starting to doubt the shop a bit as they foresee more sprinklers than another shop…

Are there people on here who want to review the plan? I’ve got 2 plans from 2 different shops, which are totally different.

Regards, Jonas
