About The Maxi-Paw Seal-A-Matic Rotor From Rain Bird

This is the 2045 Maxi-Paw Seal A Matic rotor by Rain Bird. It’s an impact rotor that pops up similar to the way most gear-driven rotors do. Two of the main kinds of rotors that are used today are gear-driven and impact rotors. So, what’s the difference? Gear-driven rotors have all the mechanisms that turn the rotor, stashed away inside the body while Impact rotors have all the mechanisms outside of the sprinkler body.

Non-Potable Water Rotors Have A Purple Top

So, Impact rotors have a straight-through water flow with no gears getting in the way. And that makes them good for dirty water applications. This model of Maxi-Paw has a purple top to indicate that it is being used with a non-potable water source. Many local jurisdictions and water districts require irrigation equipment to be marked with the color purple. So that anyone working on the system will know that the water is not suitable for drinking and may contain contaminants.

The Maxi-Paw Rotor Includes A Check Valve

This model of Maxi-Paw also has a Seal-A-Matic check valve. Having a check valve prevents low head drainage. Here’s what that means: If there is a significant elevation difference within a zone when the sprinklers shut off, the lowest head often drains the water out of the piping within that zone. This can result in puddling and erosion. A check valve will prevent water from draining out of the head. The Seal-a-Matic check valve on the Maxi-Paw works with up to 10 feet of elevation change.

This Impact Rotor Accepts 1/2 Inch And 3/4 Inch Fittings

The rotor pops up three inches above the soil. This rotor has a combination inlet on the bottom that accepts both ½ inch and ¾ inch fittings and it has a ½ inch side inlet as well. Now note. In order for the Seal-a-Matic work, you have to use the inlet on the bottom. You cannot use the side inlet when you want the Seal-a-Matic function. The Maxi-Paw can be set to 360-degree full-circle OR arc adjustable from 20° to 340°. The rotor comes with 5 standard trajectory nozzles and 2 low-angle nozzles. It has a watering distance of 22 to 45 feet depending on the nozzle installed and how the adjustment screw is set. Let’s go outside and show the adjustments.

How To Change A Nozzle On The Maxi-Paw Impact Rotor

To change the nozzle, the water should be off. Pry up the cover on the Maxi Paw. While holding the cover up with one hand, swing the arm out of the way to reveal the nozzle. Grab the nozzle. On this tab to the left, apply forward pressure as you turn the nozzle counterclockwise. And the nozzle will slide right out. Put the new nozzle in place with the long tab down. Then twist clockwise until the nozzle locks into place. You can now release the arm. Rotate the nozzle counterclockwise and then it should pull off easily. Push the new nozzle in with the short angled tab toward the top. And turn it clockwise to snap into place.

You can adjust the diffusion screw to shorten or lengthen the watering distance, also called the radius. The diffusion screw also breaks up the spray to create a more even watering pattern. This little metal lever in the back, which I’m going to call the trip switch, switches the impact from a full circle to a partial circle pattern. When the trip switch hits each side of the wings of the trip collar, the impact reverses direction. To change the pattern, also called the arc, just move the trip collars. No tools are necessary. You can set the arc anywhere from 20 degrees to 340 degrees.
