Yes, Just make sure that they have ABOUT the same GPM and precip rate, or you might get some dry spots here and there. Also make sure there is adequete coverage so you do not get dry spots, also.

Thanks,

Mixing sprays with rotors is not a generally accepted practice. The precipitation rates vary too widely. Typically installed residential rotors will yield a precipitaion rate of .3-.4+ inches per hr. Sprays ofter run 1-2 inches per hr, generally averaging 1.5 in/hr.

The best solution is to install a Hunter I20 or PGM (or equal) rotor with a very low gallon nozzle proportionate to the arc and radius to be covered if at all possible. These nozzles can be squeezed down in the teens of feet and run as low as .75 gpm. For example, a 1/2 circle 15 ft radius radius spray nozzle from RainBird willrun about 1.9 gpm @ 30psi at the head.

Hello,
Generally mixing sprays and rotors is a bad idea, although with carful planning of the precipation rates you may be able to do this. If you do this you may expect overwatering (or more watering fromt he spray headS) because they water quicker than rotors. I would take HArolds advice and install PGM rotors, which are known as "mini rotors" and with the new .5 nozzle you can adjust these to rotate about 10 feet (and thats pushing it) I would do that in your case, because both heads are rotors and will operate the same. If you cannot get these, i would use the Toro 570 spray with rotors

Thanks
