Is there a formula that can be used inorder to figure out how many zones there will be if you have the total square footage of the property being irrigated? Thanks for the help!

I remember some kind of formula years ago....wrong! Know your psi/gpm,
turf & plantings..don't "blanket", sun/shade?, most zones go (in our market)
7 to 12 gpm @ 50psi operating. Don't forget center heads as plants mature,
add mainline extensions to areas where you think future zones, add mucho
spare wire. Do provide "boiler plate" presentation folder & sell service!

I guess one could figure it out if you used the smallest spray pop-up available... say a 5' radius. However you'd be installing a gazillion of them for an average system. :)

What everyone is trying to tell you is that each system is so different based on so many factors that you have to make the sprinklers fit the area to be covered and what plant material and micro-environments you encounter on the site.

On a lot of our systems, where the planting plan is vague, or non-existant,
we will go 5' w/ our laterals & stub-outs & add/subtract heads as final
plantings come to existance; you'll never get caught with coverage issues
this way.

You're a smart man Mike. Heckuva a lot easier to cap than add. Otherwise you end up retrofitting some bizarre mix of spike sprays on 1/4" tubing with a popup zone. (We do a lot of that)

The only formula for calculating prices in any service or construction type industry is one that accounts for all costs of doing business, including profit. Basically materials, plus labor, plus labor burden, plus subs, plus equipment, plus over head and finally add a percentage to your costs for profit.

Once you learn, and it is taught is classes by a number of people, it is easy and makes sense. Your profit can be built and predicted reliably.

Well, I have not cracked open a cold Lawn Genie today, but I will now:
The sprinkler biz is NOT what all the other subs do..it's personality, it's
trust; I've watched my clients kids grow up...I've had keys & garage door
combos...showing up to check operation & dropping everything when they
have a "water feature" is this biz..It's not as anal as you describle.I think I'm
in the wrong post, but the word is still how to have fun w/sprinklers!
