If the sprinkler line breaks, you have a couple of options for fixing it. The method used to fix a broken underground sprinkler line depends on the location of the leak or split in the line. For example, clean breaks that occur before valves typically require a hard bridge repair. However, if it’s further along the line, you have many different types of repair jobs available for the task.

How Do You Fix a Broken Underground Sprinkler Line?

Locate the Damaged Pipe

First, you need to find the leak in the broken sprinkler pipe. This is the most challenging part of repairing the damaged section. Some leaks are easier to source than others.

You might notice a loss of water pressure in one watering zone or a geyser popping through your lawn. If there’s a pressure loss between sprinkler heads, examine the line in that area and look for signs of moist soil.

PVC Saddles & Clamps

The PVC saddle is the most common repair kit for connecting standard plumbing pipes. The components in the repair kit hug the line, not the fittings. If the fitting is leaking, you’ll need a hard bridge repair. Some repair kits use PVC saddles, while others use metal clamps and rubber gasket replacement parts to resolve the issue.

Flexible Couplings

Most homes have trees on their property. While they give us glorious shade in the summer heat, their roots can also interfere with irrigation system lines. A tree root can easily puncture a pipe, leading to a broken pipe and a leak.

Since most roots create an upward force on the pipe, the break might be challenging to fix a broken sprinkler using a hard bridge. Therefore, a flexible coupling is ideal in this type of pipe repair. This is the best way to resolve the issue without damaging the tree.

Expanding Couplings

Telescopic coupling is another term for expanding coupling. This is ideal for the replacement of a leaking fitting in a tight spot. For instance, if the fitting is inside a sprinkler valve box, you might use this method.

The fitting has a stationary end you attach to a section of pipe. The movable shaft on the fitting slips into another pipework fitting.

Sometimes, a repair might involve a hard bridge combined with an expandable coupling, but this strategy adds to the repair bill.

Compression Couplings

Many irrigation repair specialists use no-glue pipes and fittings for jobs wherever possible. A PVC compression coupling offers the ideal solution for this case. Also known as a dresser coupling, the compression coupling uses gaskets as a mechanical seal.

Irrigation technicians tighten the nuts on the fitting. They force the rubber O-rings into the empty space between the fitting and the pipe’s outer surface. If there’s a leak, tightening the clamp another half-turn will stop the problem.

PVC Pipe Bridge

The PVC hard bridge is a common fix for leaking sprinkler lines. This method involves building a bridge using hard PVC pipe and fittings.

This method is utilized when:

  • The sprinkler line passes over growing roots
  • You locate a leak in a small area, that isn’t suitable for the other methods

The amount and type of fittings required depend on the merits of the situation. However, most hard PVC pipe bridges utilize a series of 90-degree fittings and a section of PVC pipe.
