sprinkler heads uphill

I am helping my brother install a system. His front yard slopes uphill from his house. The road is elevated about 5 feet higher than what he wants his Pressure Vaccuum Breaker to be at the house. We thought of putting one anti-siphon valve up by the road to supply those higher heads, and using regular valves for the rest of the zones. Does this sound reasonable or do you have any other suggestions?

Never had this situation. I would maybe suggest a master valve, with AVB (Atmospheric Vacuum Breaker) after the master valve once you get out of the mainline in your house, what I'm saying is put the master valve in the house, and the AVB outside. I'm not sure if this would be the correct design, because I have never dealt with this before. I will research and get back to you on this.

Feel free to ask any questions.
Thanks!

I did some reading on some of the links and the Online Store. When I looked at the double check valves for sale on Sprinklerwarehouse.com it says that terrain need not be considered and can be placed underground. Does that mean that a double check valve can be place at house 5 feet lower than the highest head? If so, is there significant loss of pressure with double check valve?

Yes a double check valve will reduce the pressure more than a PVB, but I suggest that you use one of those rather than the AVB that I suggested before, because I read in on info also. I would suggest the double check valve. What is your pressure?

Double check valves can be installed above ground, below ground, instide, and outside. I use the DC, and i know that some say that they reduce pressure, the ones i use really don thave an effect on pressure. I would use the DC
