" If they were dirty I’d just take the filters off. That typically solves that problem."
I did this and it destroyed the low flow rotators.
So it appears that we have more than one condition going on:
* Irrigation water in northern section is drinkable, and one does not need a main filter.
* Southern sections where the water delivered has some sediment, but little green scum.
* Southern section, worst case scenario, evidently where I am, where a great deal of sand and green scum are reaching the sprinkler heads
So if you unscrew your sprinkler head and see the previously mentioned amalgam of sand and green scum, it would behoove you to get a main filter. You will not be able to pump it through. Removing the individual screen will not solve your problem. Constantly cleaning and realigning all 30 is arduous.
I do not know the intricacies of what southern village gets what pond water, or what level of light filtering, but it would appear that it is not uniform.
