    My head is going to explode, and not just because I have the flu.

    Sorry about that, i should have been more thorough.

    I was also taught not to run the valves wide open. The throw is adjusted by throttling the valve, the diffuser, the supply or any combination of the above.

    I was taught to never use the flow control or diffuser screw because PSI and/or temp will have a huge impact on how it reacts at a given time.

    That's all too true, using a flow control as a prv is stupid. The only reason to use the flow control is to prevent the valve from not shutting down. I adjusted my valves by turning the the handle down until the sprinklers began to lose radius, then open the flow handle 1 1/2 turns.

    I don't have a problem with licensing or a reasonable fee. My problem with continuing education is... why? Anything you need know about any new regulations or innovations your friends at the irrigation shop will let you know or you can ask. It's not brain surgery. (no offense) Yes an over zealous inspector can be un predictable... For example your working in a municipality that states if the distance between the sidewalk and the curb is less than 4 ft you have to water it from across the side walk, anything more than 4 ft you have to punch under the sidewalk and water from between the sidewalk and curb. Your on a job where one end of the sidewalk 3'11' and the far end 4'1''
    What do you do... put half the heads between and the other half outside and create an ugly inconsistency with you lay out for no functional reason undoubtedly creating unnecessary hassles with the rest of the layout and likely more labor. Or do you do the reasonable thing and do it one way or the other hoping the inspector (who may very well be some city managers half wit brother-in-law that just lost his job at Lowe's) isn't on his high horse. Damned if you do damned if you don't.
    I always keep the costumers interest at heart and often times that is the cost, not everyone wants or needs a Cadillac irrigation system. If the municipality dictates a Cadillac the client wants a prious ethically your bound cast that revenue aside to the bottom feeders. You should know as well as I do there are different ways to irrigate a property sufficiently with cost being the main variable. What I mean by 100% overlapping coverage is head to head coverage, one head overlapping the impact of the adjacent head 100%.
    75 or 80 percent I think is ideal. Just don't stretch your water volume to the limit with the amount of heads you use to help compensate for volume decline and you can always put in smaller apertures down the road. An over zealous inspector can nit pic on a lot of things that make no difference like imetioned earlier. More gigs, more changes to make, more re inspections, more time, more money, less profits!

    And what if the neighbor stops irrigating? Never depend on the neighbor to complete the coverage.

    Even if the neighbors don't water, the grading and lack of sunlight keeps those areas wet. Putting the 2nd row in always creates a swamp, whether the neighbor waters or not. Often when both houses have irrigation, we end up shutting that zone off to keep it from being over watered.
