Hey everybody, Just my 2 cents worth. I had a new irrigation system
installed this spring. (24 zones total) What I have found out with
irrigation people is that most don't have a grasp on watering times. My
installer, which is a large company in our area, set all zones at 20
minutes. He didn't take into account soil types, whether it was sun or shade
beds or lawn. He also set all zones to run every other day. I actually had
to rewire my controller because the arangement of zones made no sense
whatsoever. I had to regroup all lawn zones, shade beds and sun beds so all
could be watered properly. A drip zone with emiters putting out 1 gallon per
hour would certainly have to run longer than a spray head putting out 3
gallon per minute.
I think the best test is to actually measure the water being applied and
adjust watering times accordingly.
