Leaks in underground piping systems can cause significant damage and lead to costly repairs if not detected early. Hydrostatic pressure leak detection is an advanced method used to identify leaks in various types of underground pipes, including water supply lines, sewer lines, and irrigation systems. This non-invasive technique is both effective and precise, ensuring that leaks are detected promptly to prevent further damage. In this article, we will explore the hydrostatic pressure leak detection process, provide three examples of its application, and explain how AnyLeak can help you address these issues.

What is Hydrostatic Pressure Leak Detection?

Hydrostatic pressure leak detection involves pressurizing a pipe system with water to identify leaks based on pressure loss. Here’s how it works:

  1. Isolation: The section of the pipe suspected to have a leak is isolated.
  2. Pressurization: The isolated section is filled with water and pressurized to a level higher than its normal operating pressure.
  3. Monitoring: The pressure is monitored over a period of time. A drop in pressure indicates the presence of a leak.

This method is highly effective for detecting leaks in complex and extensive piping systems, providing accurate results without extensive excavation.

Example 1: Residential Water Supply Line Leak


A homeowner in Burnaby noticed a sudden increase in their water bill and unexplained damp patches in their front yard. Suspecting an underground leak in their water supply line, they reached out to AnyLeak for professional assistance.


Our team used Hydrostatic Pressure Testing to identify the leak. We isolated the section of the water supply line running through the yard and pressurized it with water. The pressure test revealed a significant drop, confirming the presence of a leak.


Once the leak was identified, we used Trenchless Pipe Repair techniques to fix the issue. This involved inserting a new pipe lining into the existing pipe, creating a durable and seamless barrier without the need for extensive digging. The homeowner’s water bill returned to normal, and the damp patches in the yard dried up, indicating a successful repair.

Example 2: Commercial Sewer Line Leak


A restaurant owner in Richmond experienced frequent plumbing issues, including slow drains and unpleasant odors. Suspecting a sewer line leak, they contacted AnyLeak to investigate the problem.


Using Hydrostatic Pressure Leak Detection, we isolated the section of the sewer line beneath the restaurant and pressurized it. The pressure test indicated a loss, confirming a leak in the underground sewer line.


To address the issue, we employed Pipe Bursting technology. This method involves pulling a new pipe through the existing one while simultaneously breaking the old pipe apart. The new pipe is highly durable and resistant to future leaks, ensuring the restaurant’s plumbing system operates smoothly.

Example 3: Agricultural Irrigation System Leak


A large vineyard in Kelowna noticed uneven water distribution and reduced crop yield in certain areas. They suspected a leak in their underground irrigation system and needed a quick, non-invasive solution to minimize disruption to their operations.


We conducted Hydrostatic Pressure Testing on the suspected sections of the irrigation system. By pressurizing the isolated sections and monitoring for pressure loss, we accurately identified the location of the leak.


We performed a Spot Repair to fix the leak. This involved excavating a small area around the leak site and replacing the damaged section of the irrigation pipe. The repair was completed efficiently, ensuring the vineyard’s irrigation system was restored to optimal performance and minimizing impact on their crops.
