Dry spots suck.
Your Sprinkler Design Has A Certain Number Of Zones And Sprinkler Heads
It would be really cheap and easy to just put all
your sprinkler heads on one zone, but your system would be highly
ineffective. The more sprinklers you put on a line, the less
pressure each head will be able to produce. That means that the
sprinkler heads won't be able to spray as far as they are designed -
leaving dry spots on your lawn.
Sprinkler Daddy incorporates the size of your water
supply line and the amount of water needed by each sprinkler to
determine the proper number of sprinkler heads to put on each
zone. This ensures that you'll get the best water coverage
