A Definitive Guide of How To Find Broken Sprinkler Pipe Underground?

Before you know how to deal with leaks in the underground pipe for your sprinkler system, you must first find out exactly where it has occurred. But the pipe is buried underground, so finding it may take time.

Here is a step-by-step guide on how to identify the broken underground house:

Most domestic water meters are situated near the road in front of the house. They are usually buried in a box with a cap covering the ground surface or home sidewall.

Many of these water meter boxes, including their caps, are made of concrete, which can be quite heavy to lift. Using a small hook system will help you easily lift the cover.

With the cap lifted off, you can now see the meter that controls water entering your home. Remove any dirt that might have accumulated on the meter to make it visible. Close off the main water supply valve in the meter box.

2. Inspect your lawn

You can also check if some of your sprinkler heads seem to have pressure differences, though this won’t tell exactly where the source is.

Cover all of your sprinkler heads with caps, then turn on all sprinkler locations and observe where water emerges from the soil.

Mark the muddy and more wet parts on the lawn and give the lawn a few days to dry to make digging easier.
