What is a commercial system?

Rainbird, hunter, and Toro are all good products. Your best bet is to go to an irrigation supply store. Im an ast. manager for one and if you bring in the precise measurments of what needs to be watered along with the amount of pressure and gallons per minute we will design it for you as long as you buy the parts from us. Almost all irrigation supply stores have a liscensed irrigator on hand so you know the system will work and be up to all of you local codes.
