Answer 2

the trick to a sprinkler system is to figure ur gpm ( gallons per min. ) from where ur getting ur water supply. take a 5 gal. bucket, time how long it takes u to fill it up. lets say it takes 20 seconds to fill up the 5 gal bucket then u r working with :

20 secs = 5 gals
60 ( 1 min. ) divided by 20 ( secs to fill 5 gal bucket )= 3
3 x 5 gal= 15 gals. per min.

then u have to buy ur sprinkler heads and make sure they dont add up past 15 gals a min. all heads r sold that way.

so if ur getting 15 gpm supply, then u can use something like:

5- 3 gpm heads or 7- 2 gpm heads.

then u have to figure zones. and u have to know how far each head will " throw" their water.

go to lowes or similar, write down what there heads r in gpm and how far each head will throw. then take a sheet of graph paper and scale ur yard. then stating in a corner of ur graph draw in a head and scale the throw. at the end of the throw place another head working down one side of the graph paper.

email me if u need to.......

First thing is to find out how much pressure you have coming out of your outside water faucet. Best way to find out the psi is to get a pressure gauge and hook it up to faucet and turn it on. If you have more than 60 psi, you can run up to 3 rainbird ( 5000 series) heads per zone. You would need 6 heads total. The 5000 series can shoot up to 40 ft. per head with different size nozzles. My company usually uses a 2 gal per min nozzle. This nozzle will shoot up to 35 ft. Rainbird has the best type of sprinkler heads because it has a rain curtain design. these heads can be adjusted from 90 degrees to 360 degrees and can be baffled down to different spray patterns.
