Having a lawn sprinkler systems has many advantages. You don't have to drag a garden hose all over your yard and straighten out all all of the kinks and twists. You don't have to constant adjust the sprinkler head to prevent the water from hitting you house or watering your driveway. You don't have to remember to turn off the water, drag the garden hose back in and roll it up.

The irrigation system is more efficient and your water bills are often lower. It is better to water once a week for a long time than to water every day for a little bit. It is best you water your lawn early in the morning (3am- 8am). This time frame is good because it is the coolest temperature with the least amount of wind.

This DIY project will save your time and money. It will also be hundreds of dollars cheaper than hiring a professional.


These were purchased at Home Depot. The materials should be cheaper at Canadian Tire but usually Canadian Tire has less of a selection. Make sure that flex pipe is tough enough to be buried but flexible enough to be curved. You don't want to have to dig up a broken flex pipe after the winter.

Call your local utility companies before you dig. This is a free service and it will identify where utility lines are buried. Some housing developments have utility lines buried only 6-8 inches below the ground.

Measure and draw the area of your yard that needs to be watered. At this stage you can figure out the length of flex pipe, the number of pop up sprinkler heads, elbow and tee joints needed.

Each pop up sprinkler will cover a circular area of 6 feet from the center where the sprinkler head is located. As you add more sprinkler heads to the same flex pipe the pressure in flex pipe will drop. After adding three sprinkler heads the area of coverage had reduced to about 5 feet.

You have to take into account the drop in pressure when you plan out the system.


End of the sprinkler system. Buried sprinkler head and L joint.

Burying the flex pipe to the second sprinkler head.

Digging the hole for the T joint and the second sprinkler head.

A completed 3 head sprinkler system. An extra flex pipe is lying beside the buried system. This hose was used to add a second sprinkler system on the other side of the lawn.

Lay out the 1/2" x 50' Riser Flex Pipe along the path where the sprinkler system will be installed. Starting from the end of your sprinkler system, using a lawn edger or flat shovel cut your lawn where the flex pipe will be buried. You don't have a dig a trench. You only have to cut a path 2 inches wide.

Now dig a hole 5" by 5" and 6 inches deep. This is where the sprinkler head will be buried. Ensure that the sprinkler head is half an inch below the ground. If your sprinkler head stick up too far it will be beheaded by your lawn mower.

Connect the 1/2" pipe connector to the end of your flex pipe and connector to your water tap.

Wrap two turns of the pipe thread PVC tape around the connector end of the L joint and attach the sprinkler head. The pipe thread tape will secure a tight fit and help prevent future leaks. Attach the other end of the L joint to the flex pipe and test out the sprinkler head. Level the sprinkler head and tightly pack soil around it.

Bury the flex pipe down to the next point of the next sprinkler head. Cut the flex pipe using your utility knife. Attach the T joint to the two ends of the flex pipe. Again wrap two turns of the pipe thread PVC tape around the top of the T connector and attach the sprinkler head. Now bury and tightly pack soil around it.

Timers and fertilizer attachments can be added to your sprinkler system. Grass will grow over the cuts and holes on your lawn where the sprinkler system was installed.
