Home - Diy How to Move a Sprinkler System Line Rachel Murdock By Rachel Murdock Updated July 18, 2017

Well-designed sprinkler systems make it an easy process to keep a residential lawn green. Landscapers arrange the pipes and sprinkler heads in a way that gives full coverage to an entire yard, allowing the recommended amount of water to soak into the ground each week.

Landscaping changes such as a new flowerbed, pool or pond, may require rerouting irrigation pipes.

However, landscaping changes may necessitate moving a sprinkler line after the system has been installed. The process is not very complicated, but it does require attention to detail.

Things You Will Need

+
  • Replacement PVC pipe
  • PVC fittings
  • PVC pipe caps
  • Sprinkler heads as needed
  • Hacksaw or PVC pipe cutters
  • Shovel
  • Rags
  • PVC cement
  • PVC solvent

Tip

Consider PVC telescoping repair fittings when you need to move a sprinkler line. They are easier to use when pipes are already in the ground, and require less digging.

Warning

Do not reuse old PVC pipe or sprinkler heads. Buy new parts when moving a sprinkler line.

  1. Lay out the location for the new sprinkler line. Determine which line needs to move and where the new line needs to go. Measure and draw a diagram.

  2. Turn the water to the system off.

  3. Dig a trench to remove the old line and a trench for the new line. Be sure the location and length of the line will provide enough pressure in the new location. Avoid 90-degree turns as much as possible when moving a sprinkler line.

  4. Cut the old pipe where it needs to be moved using a hacksaw or PVC cutters. Place caps on any ends that will no longer be connected to the sprinkler system. Clean the end thoroughly with a rag first, then install the cap with PVC cement and allow it to dry completely.

  5. Install the new pipe and fixtures using PVC cement. Consider using telescoping repair fittings for easier rerouting. Be sure to apply cement, put the pieces together, then the rotate pipe 1/4 of a turn and hold in place for 10 seconds to prevent the joints from falling apart.

  6. Install any new sprinkler heads in the correct position, if needed.

  7. Allow the joints to dry completely, then test the system. If there are leaks, repair and re-test. When there are no leaks and the sprinklers cover the ground correctly, fill the trenches in with dirt. Add seed or sod to the dirt over the trenches.
