I did my tiny .17 acres with 7 zones (7500 sq ft including house, driveway, etc). Granted, two of those zones are just for a couple of small sidewalk strips.

not to beat a dead horse or something like that. How's that FREE design working out.

One of the common mistakes that home owners make when giving rainbird the information to use to make the design is that they tell Rainbird that they have a 3/4" mainline. The mainline is what the designer says it is. If you tell Rainbird that your mainline is 3/4 inch, you have just shot your self in the foot. A normal residential mainline in Houston is 1". This will allow more gallons per minute and flow than if you tell rainbird that you have a 3/4 inch mainline. I hope this is somewhat helpfull.

Why would I tell that my supply line 1" when it is REALLY 3/4"? It won't make things any better ?(

Upsizing the piping reduces friction loss . 1" is the industry standard

However you can never get more psi and water volume then what your water meter has the ability to supply

It just gives you a better ability to work with what you have

Were they asking for the main line size going into your house to the meter, or what size pipe you plan on using for your sprinkler system main line? Two different things that will each play a role in how much flow/pressure you can maintain for your zones.

Well, I did all designing by myself using irrigationtutorials.com I have 3/4" meter and supply line but went with 1 1/4" poly for mainline and 1" for laterals.
