... I notice there is somekind of set-screw sticking out the top of the sprinkler head. I am not familiar with the SAM's heads. Do I need to do anything differnt from the regualr 5004-PC's when I install the SAM's head? Do I need to amke any special kind of adjustment?
Thanks!!!!!
It sounds like your heads came with nozzles pre-installed. That's the only thing I can think of why there would be a set-screw sticking out of the top... some adjustment for the nozzle. When I bought the Rainbird SAM heads, they just came with orange caps to be replaced with nozzles.
The SAM doesn't need anything special. Its just something added to the bottom of the head to seal it when the head retracts. Nothing to set... it just seals. However, I do know that when I bought my SAM heads, one or two of them had some of the parts missing and I had to get them exchanged (it was obvious there was no seal happening before I even attempte to install them).
