If the system uses, for instance, Hunter PGP heads and a Pro-C controller, you can fit the watering to most any well supply. As much as a comprehensive well test might be desired, it's just as easy to swap rotor nozzles if the first set doesn't match the supply.
The one thing to ask about, is if there is going to be a strainer in the sprinkler supply. A 100-mesh Vu-Flow strainer is not too expensive, and it keeps any particles out of the system.
