I irrigate my lawn using surface water pumped out of a shallow lake behind my home.  The additional solids present (i.e. algae, sand, debris, grit), as well as the inconsistent pressures seem to play havoc with most of the impact sprinklers I have tried.  Many store brand sprinklers will not even oscillate right out of the box, as they often hit the first stop and stop, literally.  I finally found the Orbit 56667N Tripod Base Impact Sprinkler on Amazon, which worked at the required pressures; but then it stopped oscillating after the first season.  I ordered this Rainbird (with  inch male fitting) to replace the Orbit head on the tripod, and the difference is staggering.  The Rainbird is by far the highest quality sprinkler head I have tried yet.  I have used specialty Rainbird heads in industrial applications, so I knew they were a well-made product.  Rainbird doesnt make many sprinklers that aren't for use in irrigation systems, which is why I didn't go with Rainbird from the beginning.  I am glad I found this replacement head, and I will be making another base connection, so that I can order an additional Rainbird head for use at my second spigot feed.  See below for additional details of the Rainbird 25PJDAC.
