Q. Does the Auto Rain Lawn Gear® Irrigation System need to be winterized?
A. No. This system has been thoroughly tested in the harshest climates and, if installed properly, will not have to be blown out. There is no need for costly service calls to blow out in the fall and turn on in the spring. Simply disconnect the irrigation line (s) from the spigot (s) and insert the plastic end cap (included in kits) to prevent debris from entering. The system will self-drain. Be sure to add the in line King Drain with tee for any low lying areas where a sprinkler head will not be.

Q. Is a timer an option for Auto Rain Lawn Gear® Irrigation Systems?
A. Yes. There are several available options to choose from. .

Q. How many Auto Rain Lawn Gear® systems have been sold?
A. There are thousands of these systems in place, working exceptionally well for customers..

Q. How many spray heads can I install per zone?
A. The Auto Rain Gear Lawn® irrigation system is available in One Zone, Two Zone or Three Zone kits. They are designed for three Rain Bird® Rotor spray heads with 1.5 gpm nozzle or four Rain Bird® #1806 pop-up spray heads per zone. Your water spigot needs to produce a minimum of 5 gpm for optimal results. You can determine your gpm by placing a metered bucket (5 gallon most common) into the water flow of your spigot and timing how long it takes to fill. Be sure no water is running anywhere inside or outside the house while testing. If the 5 gallon pail is filled in one minute you have 5 gpm. If you fill the bucket in less than one minute you have water flow that exceeds 5 gpm which is fine for these systems.

Q. Where do I start, and how do I install the Auto Rain Lawn Gear® Irrigation system?
A. For your safety it is imperative that you call Miss Dig or your Utility Companies to mark all underground lines prior to any excavation work!

1. Check the gpm (gallons per minute) at your water source or spigot (s) to be sure there is at least 5 gpm. Most households have at least this amount.

2. Plan where you will place the spray heads from the examples illustrated on this site. The Rain Bird® rotor spray heads have a radius of 20-30 feet and Rain Bird® Pop-Ups have 3‘ to 8‘, so plan to position spray heads away from areas you do not want watered such as your home, driveways, etc. You can shorten the spray radius by turning the screw at the top of the spray head until you achieve your desired distance.

The possibilities are endless, a system can be set up for any shape or size yard!

3. Order your kit (s) accordingly from the web site to do any or all of your irrigating needs. You can add on to your lawn anytime so doing a portion now is fine.

4. It is best to roll the poly pipe out in the sun to allow for ease in installation. A heavy object or duct tape can hold either end from recoiling until you are ready to use.

5. Assemble Rain Bird® rotor or pop-up spray heads as noted on the Rain Bird® instructions using the 1.5 gpm nozzle. Be sure not to use the 1.5 gpm LA nozzle. This is to be used in areas that require a low angle of water for under low hanging trees, etc. The distance of the water with this nozzle is much shorter.

6. Following the above diagram, assemble the rest of the Rain Bird® rotors using the Teflon tape and pliers to tighten fittings.

7. From your outdoor tap or spigot, create a guide line with lawn marking spray paint or string to all Rain Bird® rotors or pop-ups. Assemble entire zone above ground from spigot to last spray head being certain to keep entire system free of any dirt. Dirt must be cleaned out before going any further. Use a mild dish soap to lubricate barbed fittings and allow for ease in assembly. Be sure to cut the pipe to the desired length, put the clamp over the pipe, add soap, press together and tighten clamp.

8. Using a flat blade shovel, drive down about five (5) inches, staying on the same side of the guide lines you have drawn. Rock the shovel back and forth to create a channel for the poly pipe to be installed. The area where the spray heads are located will need to be opened about one foot square which will allow you to position the head squarely in the ground when installing. Renting a small trencher will speed up the installation.

9. Take two flat blade shovels in the beginning of the trench near the spigot. The two shovels can be rocked back and forth to create the opening for the poly pipe to be installed. An additional person will be helpful here: one to create and open the trench, and the other to push the poly pipe into position. Take one shovel at a time over the next in the direction you are headed tucking the poly pipe into the trench.  Replace soil over the freshly laid poly pipe and compact firmly over trenched areas.  Replace the earth around the spray heads and carefully compact the soil to ensure proper alignment of spray heads.

10. Adjust the settings on Rain Bird® rotors and/or pop-ups via the Rain Bird® instructions.

11. Turn water spigot on. Turn zone (s) on. Make any necessary adjustments with zone off. Repeat this process until the adjustments meet your irrigation needs.



Q. How can I install under a paved area?
A. Run a 1 1/4 " PVC pipe under the sidewalk. It may need the help of a garden hose which will also help clean it out allowing for the poly pipe to be fed through. You can also buy tunnel kits at home improvement centers.

Q. Can the Auto Rain Lawn Gear® Irrigation System be tied directly to a water supply?
A. Yes. Contact your city code for back flow prevention devices.

Q. How can I cut through the sod / grass?
A. You need sharp square shovels and thoroughly water the area of installation to soften the sod before beginning.

Q. How can I adjust the Rain Bird® 5006 Rotor?
A. See Rain Bird 5000 Series instructions in the kits or on the web page.

Q. How do I get dirt out of the sprinkler line? I had to repair a section and some spray heads are not working properly.
A. You can unscrew the top of the spray head and remove it from the base which is in the ground. Be sure to clear away earth from this area so dirt does not fall back in after flushing. Turn the water on briefly to flush out the dirt. Reassemble promptly to prevent dirt from entering.

Q. Can I aerate my lawn with the Auto Rain Lawn Gear® system?
A. Yes. Be careful not to aerate over the spray heads and not to have the aerator setting more than 2.5 inches deep.

Q. Is a permit required?
A. Contact your local city code requirements for back flow prevention devices.

Q. I don’t have a lawn yet. When do I install the Auto Rain Lawn Gear® Irrigation system?
A. The best time to install is after you have a finished grade. Install the system with Rain Bird® rotors and/or pop-ups flush with the ground if seeding and 1 inch above ground if you are going to sod.


Q. There is a low spot in my lawn where there will not be a spray head. Do I need to worry about this freezing?
A. The systems are designed to have all spray heads self drain the entire system from the spigot. If there is a dip in the yard you should install a King Auto Drain with tee from the Options page. It is a tee with an auto drain on it which will prevent that section from freezing.

Q. What if I encounter rocks or roots?
A. Rocks should be removed. Large roots can be tunneled under which is why the whole zone should be dug open in case the poly pipe need be backed up to allow room to go under roots without kinking the pipe.

Q. What if I kink the pipe?
A. There is a repair kit coupler from the Options page if the kink is bad enough. If it is slight you can form it back into shape with your finger.

Zones are designed to be in line with three rotors for LA kits and four pop ups for SA kits. Any changes to this may require a " barbed tee to split the supply line for rotors or pop ups leading in separate directions from the spigot.

A " insert tee or " insert male adapter may be needed to change the layout design for LA kits.

A " X " X " insert reducing tee or ? X ? reducing male adapter may be needed to change the layout design for the SA kits.

-Check to be sure no other water is running in the house and the spigot (water supply) is completely open.


-Try removing one of the rotors/pop ups from the zone to see if performance improves.

If so you will need to omit one of them. You can omit one of the rotors/pop ups with a " coupling or a " plug for the last rotor/pop up.
