Yard with quick elavtion change

Hi,
The house down the street from me sits about 35' from the street.
It is just your normal rectangle shaped yard but it slopes from the
street down to the house. I'm guessing the elevation change is about 6'
with most of that change being closest to the street. Yeah! Pretty
steep! Would you use a rotor as usual? It seems that any rotors at the
top would have a very high arch when pointing down hill and then the
lower rotors would have a very low arch when pointing up hill. What
would you do in a case like this?

Thanks for any advice,
Steve

Use heads with a low trajectory angle. Rainbird 5000 series rotors include some low-angle nozzles.

I was kinda thinking the same thing. Low angle for the rotors a the top and maybe high angle for the bottom rotors. Wanted to make sure though. Thanks for the reply and suggestion.

Not to hijack the thread, but I have a similar situation. What sprinklers have "high angle" nozzles? I see lots of sprinklers with low angle nozzles, but none with "high angle" nozzles?

I'm assuming the rotor has to be completely perpendicular to the ground, i.e. not angled...

Would you put check valves on the low rotors as well? Thanks!

No such thing as "high angle" rotors. In olden times, there were some brass nozzles that threw the water straight up, in order to fall back down and cover a strip of grass.

Thanks for that info, so what do you do if you have sprinklers at the bottom of a hill? In my case I probably have a 6' drop at the bottom right of the house, it's a little less on the left side, but still 4' drop. Should I just insert the sprinklers angled backwards a little so the top is perpendicular to the slop of the lawn?

Sprinklers' normal trajectory is 25 degrees, so you should not have issues with a little slope.
