The wind made a difference, and it appears that you were absolutely
right. In 12 min of sprinkling, I collected .132" at the bad spot and .305" in the good spot. Several of the bad spots are about 3 ft from a 12 ft spray nozzle, which makes me suspect overspraying. I just measured my pressure, and got 62 psi upstream of the solenoids. I set the pressure high because I have 16 sprinklers each in 2 of my sections. It would be very difficult to add more sections. I am using the better Rainbird sprinklers -- not the Home Depot version. What would be the best approach? a. Reduce the pressure? If so, what to? b. Change the sprinkler nozzles? If so, what to? c. Something else. "Tom Jaszewski" wrote in message ... On Sun, 7 Aug 2005 13:09:59 -0700, "G Burton" wrote: I've checked that, and I am within spec. In fact, the problem is just a few feet from the head. Once more....you have problem with uniformity. After hundreds of homeowners consultations over 20 years I'm stilling willing to bet you have a coverage and not a soil problem!!!
