[color=#0000ff][color=#000000][font='Calibri']Thanks guys for the quick responses. I thought 17 zones
seemed like a lot. Do you think the 61 sprinklers heads seem excessive? I know
it is somewhat hard to comment without seeing my yard layout. I also did the
free design service from Home Depot (Orbits) web site and it came up with
almost exactly the same results. I am bound and determined to do this all
myself and am trying to learn all I can before starting the project. I hate to
ask a professional to come out and give an estimate because I would feel guilty
because I have no intention on hiring someone. I have already learned a lot by
this and other great websites/forums.

I would sure like to be able to cut my plan back to 12 zones but that is such a
big drop from 17. It just doesn't seem like I have enough GPM to power 61 heads
on only 12 valves. One of my problems is I have a 4 ft. wide part that goes the
whole distant of my yard. (168 ft) And according to rain bird design it
requires 13 heads. This sound right?

Thanks again![/font][/color]

Distance from meter to the street is 30 feet. Probably like 35-40'.

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.

How long is that 3/4" supply line from the street to you meter? Just curious.

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.

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

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.

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

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
