23 spray heads!?

Question

23 spray heads?

I was walking with my friend when i saw someones underground sprinklers turn on and he had 23 sprinklers to 1 zone! how is this possible, it was just a residential no pump and they didn't have that much pressure but they still worked to do the small strip around his yard most of them were half rain bird sprayers, what size of pipe do you think they used, and do you think that funny pipe gives more pressure?

Answer 1

If you think about it, all that water has to go somewhere, the prssure will build up so it goes out. I am guesing they had 1 inch or 3/4 inch mainline and then 1/2 inch funny pipe. Those heads are designed to work at low pressure.
