Rain bird impact sprinklers quit rotating
I just replaced several Rain Bird Impact sprinkler heads and one of them always stops rotating. It rotates for a minute or so then always stops at one end of its rotation. Another sprinkler does the same thing but less frequently. On the one that does it all the time I changed the coupling that the head threads into because I thought maybe it was somehow impeding it, but that didn't help. Any ideas?
Are these Maxipaw impacts with blue nozzles? what's the water pressure?
Blue nozzles
They do have blue nozzles, but they are Rain Bird branded. I do not know what the water pressure is. I suppose I should figure out how to check that.
Maxipaws take smaller nozzles than the blues, if the water supply is too small, and there is a way to "reseat" the end of the arm spring, to make the head more reliable at low pressures.
