Broken Sprinkler System Pipe? Here's How To Fix It

Posted on: 29 May 2017

If one of your sprinkler system's underground pipes has broken and is leaking water, then you need to repair it. Since most sprinkler systems use PVC pipe, this type of repair is simple and you can fix it yourself even if you do not have any plumbing experience, using this procedure:

Step 1: Turn Off the Water Main's Shut-Off Valve

Before you start repairing your sprinkler pipe, first you need to shut off the water using the water main's valve. This will prevent your pipe from leaking water while you are trying to repair it.

Step 2: Dig Out the Area Around the Broken Pipe

Carefully remove the grass above the leaking pipe using a shovel so it can be replanted when you are finished.

Dig out the pipe so that you have easy access to make your repair. You need at least a few inches on each side of the pipe and below it.

Step 3: Cut Out the Damaged Portion of PVC Pipe

Using a hacksaw or a PVC cutting tool, cut out the damaged section of pipe. Make sure you cut the pipe back far enough that there are no cracks or other damage.

Step 4: Prepare a Patching Piece of Pipe

Using a spare section of PVC pipe, cut a piece that is the right length to make the repair. Since you will need to attach the new section of pipe using couplers, make sure you leave enough room for them on each end.

Step 5: Sand and Prime Each Piece 

Before you can glue the new section of pipe into place, first you need to sand:

  • both ends of the old pipe
  • both ends of the new pipe
  • all four internal surfaces on the couplers

Once you have sanded each enough to rough them up, then you need to wipe them down with a damp cloth to remove any dust. Once cleaned, paint each piece with PVC primer and allow it to dry.

Step 6: Repair the Broken Pipe

Place PVC glue on each pipe end and inside of the couplers and patch the underground pipe. Hold the patch in place for a moment so it will cure correctly.

Step 7: Test the Repaired Pipe for Leaks

Let the PVC glue dry for a few minutes and then turn your water main back on and check the pipe for leaks. If you discover a leak then you need to cut the patched pipe section out and start again.

Step 8: Re-Bury the Sprinkler Pipe 

Finally, once you are certain that the repaired pipe will not leak water, then you need to re-bury it with soil. Using the soil you removed, refill the hole and then place the lawn back into place.

A Perfect Father’s Day Gift

Growing up, I was daddy’s little girl. I absolutely adored my father. Thankfully, I still enjoy spending quality time with this special man. Because Father’s Day always comes up fast, I’ve tried to come up with the perfect gift to give my dad. I've decided to hire a landscaper for my father. My dad’s farmhouse is situated on 70 acres of land. While his front yard is filled with shrubs and flowers, his back yard is relatively void of any vegetation and could use an update. A landscaper would make my father’s back yard as beautiful as his front yard. On this blog, I hope you will discover the benefits of hiring a landscaper for your dad for Father’s Day this year. Enjoy!
