Repairing a Drip System With Poly Pipe Repairing a Drip System With Poly Pipe

What You'll Need
2 1/2 inch couplings
Small hacksaw or knife
Tape measure
Poly pipe

Poly pipes help connect emitters to drippers in drip irrigation systems, also called trickle irrigation. This method saves fertilizer and water, by dripping the water slowly onto the roots of the plants, or the surface of soil, with the help of a network of emitters, pipes and valves. New technologies prevent the clogging of waste materials that block the dripping of water. Drip irrigation also helps in water conservation, by reducing the evaporation and deep drainage. The drip system should be properly managed and maintained once it is installed. These systems are more efficient than sprinkler systems, hence the are commonly adopted in places which suffer from scarcity of water.

Drip systems are not only used in farms but also in gardens. They are usually installed with, poly pipes as it is very flexible and easy to maintain and work with. No matter how good your materials are, repairing will be a part of maintenance. Repairing a drip system with poly pipes is a task made easy if the steps given below are followed.

Step 1: Locate the Damaged Section

First locate the section of the drip system that is damaged. It can be easily located because water will be leaking from the pipe and the pipe will be wet. Before you can proceed with the repairs, turn off the irrigation system. 

Step 2: Make Room for Repair

Use a shovel to dig around the area where the repair has to be done. Dig out either sides of the area to be repaired, as well as few inches below the poly pipe. Dig carefully, and do not damage the pipes.

Step 3: Cut the Damaged Pipe Section

Use a hack saw or knife to cut off the section of the damaged poly pipe.

Step 4: Measure the Damaged Pipe Section

Use a tape measure to measure the damaged section of the tubing that you removed. 

Step 5: Cut a New Piece of Poly Pipe

Use the measurements taken from the tubing that was removed, and cut a new piece of the poly tubing.

Step 6: Attach the New Pipe

Push a 1/2 inch coupling onto both the ends of the new piece of poly pipe. Push the other end of each coupling onto the poly tubing that already exists.

Step 7: Testing

Now, turn on the water flow through the irrigation system and check for leaks. If leaks are found, they must be repaired again. 

Step 8: Bury the Pipe Back to the Ground

After testing, if water does not leak from the repaired section, bury the repaired section properly. You have successfully repaired the poly pipe drip system. 

Tips and Warnings

  • You can use a capped 1/8 inch emitter line, if you are repairing a pinhole less than 1/8 inch in diameter, instead of cutting and replacing an entire section of poly pipe.
  • Remove any junk around the pipe that may have been the cause of the damage.
