Thanks all for the encouraging comments!
My crash project this week is to re-design the lawn irrigation system away from the wasteful and inefficient spray type heads, to the newer rotating multiple streams design nozzles.

Spent the day today measuring with a yardstick the current sprinkler installation and then matching the flow rate and emitter distance needs with dozens of nozzle options from Hunter Industries. So, in addition to a more uniform lawn watering pattern, I should be able to reduce my water consumption by 30%. Kind of important during this California drought we are in. But I am $200 poorer this evening after placing an online order for the new sprinklers.
