The spray arm has a ferrule and an O-ring seal on it, and it screws into the body of the sprinkler. Pull out the filter and clean it in a bucket of water. There is also the spray arm itself, which is a hollow aluminum tube with holes in it (on some sprinklers there are nozzles on this tube): While you have the sprinkler in hand, disassemble the head, which you can usually do by removing a few screws. When the sprinkler is running, the cam rotates slowly - at roughly 1 revolution per minute (rpm) - this is what causes the arm to oscillate back and forth. For outdoor irrigation use with cold water only.Connected to the knob there is small arm that gets pushed and pulled by a heart-shaped cam. Recommended operating pressure is 40 PSI. The Saturn IV replaces rotors from Orbit, Hydro-Rain, and other major brands. MPT Funny Pipe fittings, swing fittings and risers. male pipe thread (MPT) Blu-Lock combination swing joint, although it is compatible with 1/2-in. The state-of-the-art approach to mounting a Saturn IV is on a 1/2-in. The can and riser stem are made from high impact ABS and metal components are made from stainless steel.Īdjustment of both the radius and arc requires the included gear-drive rotor key. It also includes a bottom inlet filter which helps prevent clogging of the nozzle. I was unable to get it working correctly again.Go see my new video th. Deflector Shield Assembly Push deflector shield into stream to reduce coverage. ![]() It includes a radius adjustment screw which allows you to reduce the rotor throw down to 75% of its rated distance.

It also includes a matched-precipitation nozzle rack with 0.5, 1.0, 1.5, 2.0, 3.0 and 5.0 GPM nozzles featuring a unique keyway design to ensure highly uniform close-in and far-out watering. By simply unscrewing the top, the shaft can be replaced or repaired. This very low rate reduces the risk of runoff or puddling for many soil types and conditions. The rotor sprinkler head uses water pressure that pushes the head out of the ground, as well as rotates the gears. It comes with a pre-installed 2-gallon-per-minute (GPM) nozzle which results in a full-pattern precipitation rate of 0.30 in. Inlet Connection: ½-inch threaded National Pipe Thread (NPT) Sprinkler Connected: ½-inch threaded Male Pipe Thread. pop-up height ensures that the nozzle clears tall grass. Its arc is adjustable from 40 to 360 degrees in precise increments, which gives you the ability to aim it so that the water hits the landscape only and avoids any hardscape surfaces.
