How to find and repair a leak in a sprinkler system

In June 20, 2016

One of the biggest tell-tale signs that your sprinkler system has a leak is your increasing water bill! Of course there are other signs that indicate a leak in a sprinkler system. These include the following:

  • Sprinkler system heads have reduced pressure, when compared to normal flow.
  • Damp or mold in your basement or lower walls. This can happen if your sprinkler system pipes run close to the foundations of your home.
  • Waterlogged lawn or soggy lawn that never really dries out.

Here’s what to do if you suspect a leak in your sprinkler system:

  • Determine if there is a leak by looking for tell-tale signs. Find where the leak is coming from. Keep in mind that this doesn’t always mean that the leak is located where you find excess water. Gravity plays a role in where water runs to and settles.
  • Finding the leak is typically easier to do if it is above ground. Unfortunately, leaks below the ground aren’t easily seen and can be a challenge to locate. You would definitely need a professional to assist you. The first step is to turn the sprinkler on and check that all sprinkler heads have the same pressure. If one has less pressure, then you’ll know that the leak exists between the previous sprinkler head and that one. Now you can examine the lawn in this area, for water bubbling or an area that seems soggier than the rest of the lawn.
  • If all the sprinkler heads have the same pressure, you might be dealing with a leak that’s quite small and not easy to locate. To find this leak you will need to put in a little more effort. Replace all the sprinkler heads with capped heads. These are screwed into the sprinkler rises and increase water pressure. Turn the water on once more and re-check the heads for pressure.

Some leaks, such as in the case of bad pipe joint seals, seal clamps can merely be tightened or replaced to solve the problem. In other instances, the leak might be coming from a broken riser or pipe which means that the piping will need to be replaced. Always ensure that the leak is in fact repaired, before you start using the irrigation or sprinkler system again. If you want to ensure that the repair is corrected and that you can avoid future costly leaks and maintenance efforts, have an irrigation expert come in to assist you.
