Hi there,
Two years back I installed Rainbird's rotary nozzles to replace the traditional Toro 570 sprinklers due to too low water pressure (around 20 psi) and lack of coverage. Things improved a lot after changing out to use the Rainbird's rotary nozzles as they could reach far greater distance given the same water pressure and the nozzles reduced water pressure much less (per nozzle) compared to the Toro's 570 nozzles. Water pressure was more usable -- around 28 psi with the Rainbird rotary nozzles.
This summer has been a hot summer, and I am starting to see dry patches -- right along the edge of the lawn.
When I looked closer, I realized the Rainbird's rotary nozzles shot out fairly far--except when the spray moved close to the edge--the spray length shortened significantly at that point (e.g. from 20 feet to 10 feet).
This resulted in a 6 inch wide of long dry strip along the edge. The hot summer exposed this problem as that area received less water than the rest.
I experimented by changing it out to use a Hunter MP Rotator MP3000 today. But the MP3000 exhibited the same problem where the spray length shortened when it got closer to the edge.
The only way I think I can solve this is to adjust the MP3000's arc to cover wider than the edge of the lawn, so that the last 6 inches where the spray length gets shorter as it would get close to the end of the arc is outside the lawn's edge. This would create an overspray problem however.
This sounds an odd solution -- and wastes much water. I wonder if anyone has any other suggestions?
Don't know if there's a better nozzle that provides these same benefits as the rotary nozzles and also keep the edge coverage even (heard about Toro's Precision Spray nozzles, but it can only reach 15 ft max -- I need something that can reach 24-26 ft).
Also the runtime with the Rainbird rotary is fairly long with the large lawn, so if I can improve to get a bit of shorter runtime to achieve the same precipitation that would be really helpful. It is taking 5 hours to irrigate the front lawn now.
Current sprinkler head-to-head distance is about 24 feet on the main lawn.
How about Toro Precision Stream Rotating Nozzle? Anyone knows if it covers the edge better than MP Rotator and Rainbird rotary nozzles? Or Rainbird's 3500, 5000 series?

Thx.
